When it comes to impressing, enter-taining and in some cases scaring the living daylights out of exhibitors and visitors, the recent bC India show in Mumbai will take some beating.
The forthcoming bauma construc-tion equipment jamboree in Munich will have to come up with something spe-cial to top the entertainment offered in one of the Indian halls.
You see, some person seems to have arranged for a very large, aggressive- looking bird of prey (I think it was a kite of some sort) to spend the duration of the show flying from rafter to rafter, and regularly swooping down, stopping visitors in their tracks and occasionally causing amazement.
He would descend spectacularly but harmlessly from his lofty perch, pre-sumably to take a closer look at the construction equipment components on the stands below or perhaps just to grab a cookie from the coffee stand. Whatever, it was good to watch.
It was a terrific ruse. If the show got a little slow, then endless minutes of fun could be enjoyed watching the feathered exhibitor performing his aerial routine.
Which raises the bar for the bauma trade show in Munich in April. It prom-ises to be a mega, unmissable event for the sector with a host of new prod-ucts to be unveiled.
But what if there is a lull in the action at bauma? What if the aisles become quiet and attentions wander? Pre-sumably some forward-thinking bright spark will have arranged for an impres-sively huge German vulture (are there any?) to be ready to fly into action and soar among the grand halls entertain-ing the masses below.
The Mumbai bird show was impres-sive. The heat is now on bauma.
And for news of any bird sightings at the show you can follow us, where else and quite appropriately, on Twitter. dpi
A Mark Twain character once ut-tered what might be a seminal truth concerning humanity. “Faith,” said Pudd’nhead Wilson, “is believing what you know ain’t so.”
All of us believe in things that “ain’t so.” Often the real issue is determin-ing what’s so and what isn’t. That came to mind on seeing an analysis of the environmental impact of indi-viduals driving automobiles vs. using public transportation (buses or trains).
Clearly, public transit would be one of those things we know is bet-ter for the environment — how could it not be? — since it moves many people at a time vs. cars that carry far fewer (1.59 people per trip, ac-cording to the U.S. government). Yet the potential of mass transit is seldom fulfilled. The average U.S. bus carries 10 people per trip, while rail systems carry an average of 25. The question then becomes what’s better for the earth, operat-ing small, unfilled vehicles or large unfilled vehicles?
Government data indicates that traveling a mile by car uses 3447 Btu of energy per person. By train, it’s 2520 Btu per person/mile, with buses at 4118 Btu. The train is the clearly the “greenest” choice. But trains can’t go everywhere.
And if they’re powered by electric-ity (often the case in light rail), there might not be much emissions reduc-tion. A lot of power here is still gener-ated from coal. So is shifting a number of small emitters to fewer big emitters really a net gain?
This isn’t to suggest that mov-ing the greatest number of people in the most efficient manner isn’t a really good idea. It’s just that when it comes to weighing options, some fundamental rethinking might be in order so we all understand what’s truly so and what ain’t. dpi

Reducing PM Hazards
Aftertreatment technology being used to cut particulates at urban construction sites
While diesel exhaust has long been known to be generally harmful to human health, some of the latest indications are that it could be more dangerous than previously thought. Information
from the World Health Organization suggests that the car-cinogenic link between diesel exhaust and cancer might be more significant and direct than suspected.
In particular, construction machines operating in urban ar-eas have been identified as significant concerns, as they are major emitters of particulate matter (PM) and responsible for an estimated 25% of all such air pollution in inner city areas. This machinery can have a very long service life and is of-ten utilized many hours a day, over many years. Much of this equipment is without suitable exhaust gas treatment tech-nology, and studies have revealed that construction workers who are exposed to high concentrations of PM may be twice as likely to develop cancer as the average person.
As that has become more widely known, a greater num-bers of builders, developers and estate owners have begun stipulating in their invitations to bid that all construction ma-chines used in their building projects must be equipped with appropriate emissions reduction technology.
Among the companies supplying that technology is Ger-many’s HJS Emission Technology GmbH & Co. KG. Among its systems designed to reduce harmful emissions from diesel exhaust gases is the modular Sintered Metal Filter (SMF) system, which was specifically developed for appli-cations in the medium to high power range.
The SMF filters, which will be on display at bauma 2013, utilize Continuous Regeneration Technology (CRT) to break down the particulates that collect on the SMF substrate. HJS said the system combines an efficient diesel oxidation catalyst (DOC) position upstream of the sintered metal filter. Optimized tuning results in the soot being continuously and passively regenerated from the sintered metal filter.
HJS has also developed active technologies such as a sintered metal filter with autarkic thermoelectric regenera-tion (SMF-AR) designed for systems operated for long pe-riods at low loads where exhaust temperatures remain low. HJS said the SMF-AR system is capable of removing 100% of the soot particles from the exhaust gases. Through resis-tance heating, it generates the temperatures necessary to burn off the particulate matter, enabling regeneration under practically any engine load, from idling to full throttle.
As a rule, HJS’s aftertreatment systems replace the ma-chine’s original silencer and they can be customized as re-
quired to match specific equipment. HJS said its systems are VERT-certified and have been installed in more than 20 000 vehicles and machines. The company also offers retrofit solu-tions for construction machines that are tailored to the specific requirements of the machine’s make and model.
In cooperation with construction companies and filter manufacturers, the German Senate Dept. for Urban Devel-opment and the Environment has initiated a field trial for die-sel particulate filters in construction machinery. According to HJS, the aim of this initiative is to cut particulate emissions from all mobile machines in operation in Berlin. From 2014 on, all construction machines used in the fulfilment of public construction projects in Germany’s capital city will be fitted with a diesel particulate filter.
This program follows Berlin’s establishment of a Low Emis-sions Zone for road vehicles through which more than 60 000 diesel vehicles have been retrofitted with a particulate filter. Results have shown that particulate emissions from diesel-powered vehicles have been cut in half. dpi

A Model Of EfficiEncy
Linde Hydraulics’ new LSC+, monoblock and stop/start system all aimed to enhance machine operation
Linde Hydraulics is focusing its presence at bauma 2013 on efficiency. Highlighting that fo-cus will be a live demonstra-
tion, using a model excavator, of the company’s new LSC+ control system.
The company said the LSC+ system brings together the properties of the established Linde Synchron Control system with the benefits offered by an electronic control. The electronics are designed to identify the operator’s in-tentions and set the pump and valves to a high dynamic or fine control range, depending on the requirement.
In addition to automatically detect-ing the working situation, the LSC+ system enables operating modes to be selected manually via the operator display. The conventional load-sensing control, which operates on top of this function, means that sensors are not required, Linde said.
tronic LINC controller detects a de-fined standstill in driving functions, the machine’s engine is shut down. As soon as the operator depresses the accelerator pedal or moves the steering wheel or joystick, the hy-draulic pump — fed by the charged accumulator — begins operating and the engine starts and is ramped up to a preset speed.
This starting procedure is four times quicker than starting using an electric motor, Linde said, ensuring the ma-chine is immediately ready for opera-tion. The intelligent automated start/stop system not only saves energy, but also reduces the amount of noise produced by the machine, the com-pany said. dpi
The monoblock valve system is an-other new product that was specially developed for the LSC. Linde said the monoblock system integrates all key hydraulic control functions within a single cast housing. This system was developed by Linde Hydraulics based on the design principle of its VT modular series. An optimized flow path ensures the minimization of pressure losses, while additional functions can easily be added by valves in sandwich design.
Linde Hydraulics is also unveiling another energy-saving function for the first time at bauma 2013 — a hydraulic start/stop system that can be used in wheeled loaders, telescopic handlers and other construction machines.
The system works with a compact hydraulic accumulator charged via a Linde Hydraulics MPR 50 medium-pressure pump. When Linde’s elec-

Cleaner Fuel VIA NANotechNology
Cummins Filtration develops new fuel filtration media based on nanotechnology
By RoBeRta PRandi
Cummins Filtration has devel-oped a new line of fuel filtration products that utilize nanotech-nology in the filtration media to
provide enhanced levels of efficiency and removal of harmful particulates from diesel fuel. The company said its NanoNet filters mark the first time that a nanotechnology-based filtration media has been commercially developed for fuel filtration within the industry.
The new filtration media has de-buted in Cummins Filtration’s Fleet-guard products, but starting early this year, it will also be available for other Cummins Filtration product segments.
“Cummins Filtration utilizes several types of patented media technology,” said Loick Menez, Director Engineer-ing Europe, Middle East, Africa and India at Cummins Filtration. “Prior to NanoNet we developed and patented StrataPore — a multilayered synthetic media offering three layers of gradient protection which is used both for fuel and lube applications — that still is the benchmark within the filtration indus-try for mobile applications.”
Cummins Filtration said the NanoNet advanced media represents the next frontier in filtration efficiency and has
or water droplets, and the quality of fuel is seldom granted, the capabilities of NanoNet are a must to protect the injec-tion components and the whole engine from any damage,” he said.
Cummins Filtration said the World Wide Fuel Charter (WWFC) has de-termined that 50% of the fuel dis-pensed at retail fuel pumps around the globe does not meet the neces-sary cleanliness of ISO standards recommended by ISO 18/16/13 (ISO 4406 Contamination Code).
Cummins Filtration said it under-took rigorous testing during the devel-opment of NanoNet, not only in labo-ratory but also in real-life applications where an engine and filter are subject to exposure to dirt, dust infiltration and extreme vibration.
Menez added that, for some applica-tions, it could also be recommended to adopt two-stage filtration system where stage one uses a conventional filter, and a second stage with a NanoNet-based filter would be used to assure the removal of microparticles. dpi
been engineered to meet the require-ments of advanced engines utilizing high-pressure, common-rail, fuel-injec-tion systems, working at pressures up to and beyond 2000 bar.
“The media traps 98.7% of all parti-cles as small as 4 µm (12 times smaller than the smallest particle visible to the human eye), to deliver superior protec-tion and performance critical to today’s high pressure common rail engines,” Menez said. “In fact, NanoNet fuel fil-tration products exhibit between seven and 13 times greater retention of harm-ful particles within the fuel filtration media during engine vibration and fuel surge than the closest competitor.”
Fuel surge results in a fluctuation of fuel flow within the system whenever the engine’s output is increased or de-creased through throttling.
Menez said the actual performance of the filter media is given not only by the size of the pore (efficiency) — thus the smaller size of the particles which are allowed through — but also from its porosity, or the number of pores in a layer of media (capacity). “As modern engines using sophisticated injection systems do not particularly love a con-taminated fuel, either by solid particles

Unlike conventional synthetic and cellulose me-dia, the new NanoNet filter media by Cummins Fil-tration is designed to have a consistent pore size due to its small fibers. Thus, its filtration capability is better shown by the number of particles which are captured by the media over the number of particles sent to the system (Beta ratio measure-ment), instead of efficiency percentage. NanoNet provides a beta ratio of 1000 at particles down to 4 µm or, 98.7% filtration efficiency with particles down to 4 µm.

New Power From Scania
Company launches new range of Scania diesel-powered generator sets from 250 to 665 kVA
By Bo SvenSSon
It’s rare when an established com-pany in a mature industry launches itself into an entirely different mar-ket segment. Now Scania, best
known for its long history of manufac-turing trucks, buses and marine and industrial diesel engines, is doing just that with the debut of a new range of generator sets for standby and prime power applications.
The new Scania Gensets are all pow-ered by Scania engines and will cover 250 to 665 kVA for prime power and standby applications. For higher power
vide comprehensive solutions closely adapted to customer needs. Customers in mining and construction operating on remote sites were already getting Sca-nia support through trucks and Scania-powered off-road equipment. Adding generator sets was a logical step.
The Scania Gensets will be offered exclusively with the company’s latest 9, 13, and 16 L diesel engines. The 16 L engine is a V8 configuration, while the 9 and 13 L diesels are inline five- or six-cylinder engines.

The new gen-sets will be available in open or closed units in 50 or 60 Hz con-figurations and will be offered in select-ed markets, with a number of units hav-ing already been delivered to the UAE, Southeast Asia, Japan and Norway.
While the Scania Genset range is new, the company does have power generation experience, as it is a long-time supplier of engines for power gen-eration. The move also came naturally in light of the company’s strategy to pro-

A new V8 engine with Scania com-mon rail fuel injection and power out-put up to 800 kVA will be added to the generator set range by the end of 2013, the company said.
“We are now starting to sell com-plete Scania Gensets via our distribu-tor network,” said Robert Sobocki, se-nior vice president, Scania Engines. “Being a Scania product means that it will have the same support as a Sca-nia engine or a Scania truck, including technical documentation, parts sup-ply, service and repair for the entire product, including the electrical com-ponents such as the alternator.
“Gaining experience from selling complete products instead of being a component supplier will serve to enhance the offer to existing gen-set manufacturers. They will get even bet-ter adapted engines and even better support in the future.”
Scania said its new gen-sets are a perfect fit for continuous operation and unlimited yearly operation time at varying loads. The units are capa-ble of providing 10% overload power for one hour in a 12 hour period, the company said and are available in fuel optimized versions or Stage 3a compliant versions.
“Even if prime power is the main tar-get for the Scania Gensets, they can also be used for standby power applica-tions,” Sobocki said. “In case of power loss, the gen-set will respond instantly.
“The sets are designed to handle high load variations effectively and the Scania engines make a true difference when power supply is imperative.”
Scania’s own systems for engine management and emissions control ensure an attractive blend of perfor-mance and operating economy, said Lars Eklund, Scania’s sales director, Power Generation Engines.
“Scania’s solid reputation for oper-ating economy and durability, coupled to easy installation and emission com-pliance, fits perfectly in power genera-tion,” Eklund said. “With the support of our global sales and service network, it’s a strong and flexible offering.”
The alternators used with the Sca-nia diesels are to be supplied by Mecc Alte and Stamford. The brushless alternators incorporate fully digitally controlled voltage regulators with an accuracy of ±1%, Scania said. Robust alternator winding protection is de-signed to ensure reliable operation in the harshest conditions.
Following Scania tradition, the con-trol panels are engineered to be intui-tive and user-friendly, ensuring swift and secure operation. Data is clearly visible and readable also in dark con-ditions, and the display is designed to withstand tough treatment and foul weather. Control panels for multiple and synchronized gen-set installa-tions are optional, as is remote com-munication and monitoring.
“Scalability and flexibility is excel-lent, and up to 32 Scania Gensets with the same or different power outputs can be combined in order to match both the given load require-ments and the demand for backup power,” Eklund said. “Furthermore, relatively small units that are easy to handle and to synchronize mean a powerful advantage when time-to-business is a crucial factor.
“Expanding the system when needed is also easy and the modular design of the engine allows for cost-efficient maintenance and high parts availability.”
Scania Gensets are based on a modular design, which is intended to simplify installation, service, mainte-nance and upgrading. The gen-sets can be configured in two versions, open or closed canopy, either tailored to meet specific application demands.
“Multiple installations of Scania Gensets are the most modern and flexible way to meet large power re-quirements,” Sobocki said. “Compared to bigger and more costly generators, multiple installations can excel in ev-ery discipline — from availability, re-dundancy and ease of maintenance to overall system reliability.
“Furthermore, load variations can be handled more effectively and in a way that optimizes fuel economy, power output and engine service life.”

deutz’s Future After guiding company through economic crisis,
Deutz AG Chairman Helmut Leube sees global challenges, opportunities
By Mike Osenga
Dr. Ing. Helmut Leube became chairman of the man-agement board of Deutz AG, the Cologne, Germany- based engine manufacturer, in February 2008. This meant that Leube arrived just in time to guide Deutz
through the global economic crisis of that year and the most-ly tepid recovery of the world engine markets since.
With a doctorate in mechanical engineering from RWTH Aachen University in Germany, Leube joined BMW in 1987 and was department manager for engine production at the company’s Munich, Germany plant. He was later depart-ment manager for purchasing engine and suspension, and project leader for production of the BMW 5-series. Subse-quent stops included vice president of BMW Group logis-tics, president of BMW Manufacturing Corp. in the U.S. and chief operating officer of Webasto AG.

“We build no two engines the same. I would call us a mass manufacturer of
individual engines. Further, the production we have put in can be easily expanded, it is a modular design and we can easily
expand it with the same concept. It provides us with an opportunity to
add capacity where needed.”— Dr. Ing. Helmut Leubechairman of the management board, Deutz AG
Since Leube’s arrival at Deutz, the German manufac-turer has expanded and changed its ownership struc-ture with its major shareholders AB Volvo Group and the SAME Deutz-Fahr Group; expanded significantly in China
through a variety of joint ventures including its recent Deutz Engine (Shandong) Co. Ltd. venture with Shandong Chan-glin Machinery Group Co. Ltd., a Chinese manufacturer of agricultural machinery and construction equipment that will build the model 2011 diesel in China.
Deutz Engine (Shandong) is the third joint venture that Deutz AG has set up in China. Deutz AG and FAW Jiefang Au-tomotive Co. Ltd. operate the Dalian-based joint venture Deutz (Dalian) Engine Co. Ltd., while Deutz and Weichai Power oper-ate their Weifang Weichai-Deutz Diesel Engine Co. Ltd. joint venture in Weifang. Deutz AG also has a sales and service company in Beijing.
Further Deutz supply agreements with partners Volvo and SAME have also expanded and changed significantly over the four years he has been chairman.
Leube spoke with Diesel Progress about the status of Deutz today and the direction in which the historic German engine manufacturer may be headed.
Regarding the change in Deutz’s ownership structure, specifically Volvo assuming the strategically important 25% (plus 1 share) position:
“Volvo now is our biggest shareholder,” Leube said. “It is important to mention that we have had a very stable share-holder structure for many years with Volvo, and with SAME being our strong supporters during the financial crisis.
“What happened was a switching of positions. SAME re-sumed its 8.6% ownership stake and Volvo moved to the 25%-plus level. This underlines and strengthens our inde-pendence as an engine manufacturer. That is very impor-tant for us — to remain and stay as an independent engine manufacturer in the future.

“But it is also important to have two strong anchor shareholders, which rely on our supply role in both the cur-rent business and the future business.
“Volvo is our biggest customer, SAME is our third-largest customer. Thus the share structure now also more reflects the business structure.
“For Volvo it is very important to underline our strategic partnership for the future. As you know we have some quite interesting plans ahead of us for expanding our current business relationship specifically in Asia.”
Regarding balancing Deutz’s market segments:
“This is a strategic focus — lessons learned from the financial crisis, if you like.” Leube said. “We are a cyclical company, but we also want to reduce our cyclicality to a certain feasible de-gree and we are looking in-depth at ex-panding our global customer structure.
We looked into the cycles of ag-riculture, the cycles of off-highway mobile machinery business and we saw that they follow more or less the same pattern, but with a certain de-lay. This gives us a certain degree of counter-cyclicality.
“In a normal crisis like those we have seen in the past (not the most

recent one) we also see regional dif-ferences. That’s why we also want to expand regionally, or globally, in order to become less cyclical.”
On the company’s position in the commercial vehicle markets:
“In automotive we have two big
customers, Volvo and FAW (the joint venture in Dalian, China), plus many smaller customers with specialty ve-hicles,” Leube said. “Our relationship with Volvo Truck will now change. They decided, two years ago that they will use their own medium-duty platform from Euro 6 onwards. This will shift our main focus in the automotive business more towards China and FAW, so our venture in Dalian with FAW, which is a 50/50 joint venture, already has 80% automotive engines today.”
Deutz is currently finishing a signifi-cant expansion of production and engineering in Germany. Why now and why in Germany?
“We are very proud of the fact that we designed and developed sub-4.0 L engines at the lowest point of the financial crisis,” Leube said. “As a re-sult, we are now coming to the market with new engines, just in time, at the right point in time.
“We are proud of the new engine design, the new engine platform, and the new engine performance … these new engines provide us with a lot of opportunities for the future.
“These engines are designed for both industrial and agricultural use

and they are structural engines, com-pared to our model 2011 engine, which while very successful in the market, was never designed for agri-cultural tractor applications.
“So with these engines we are ac-quiring new customers and new proj-ects with existing customers.
“As to why now and why in Ger-many: We are on a journey of continu-ous improvement. We have improved our product quality. We have improved profitability and in addition to that we have also changed our production system, logistic systems, and the new assembly line for new 2.9/3.6 L die-sels, and later on for 2011 engines.
“It is a completely different ap-proach in assembly compared to the processes you might have seen in the past, which were highly automated processes, installed in the mid-1990s.
“Now we are looking at less auto-mated processes, lean processes, flexible processes. The new 2.9/3.6 line is designed in a modular ap-proach, decreasing cycle time, in-creasing efficiency. This concept, which you could call lean process, has been seen throughout the indus-try, but we modified it to fit our needs.
“We build no two engines the same — I would call us a mass manufactur-er of individual engines. This modular assembly line design serves also as a copy/paste model for the production system which we will install in our two new joint ventures in China.
“Besides the changes in production in Germany, we have recently completed a €6 million investment in a new R&D facility in Cologne. Our main engineer-ing center for our base engine design is here and will remain here in the future.
“But we want to be closer to the cus-tomers with application engineering. We already do this in Atlanta for our American customers and in Beijing for our Chinese customers. We will ex-pand this concept further through our growth and expansion within China.
“But the idea is that our base engine design will be here in Cologne, keep it

centralized, but taking application en-gineering out to the major markets.”
Regarding China and Asia:“We are following our customers,”
Leube said. “So Asia is priority num-ber one. Within that, China is the num-ber one priority.
“We not only want to expand our global footprint, but also to expand our research and development footprint, as well as our purchasing footprint, in Asia.
“One of those ventures has been announced with the Shandong Chan-glin Machinery Group Co. Ltd. This is a different venture from the past. This is a production joint venture only and we are the majority shareholder. This joint venture will produce the model 2011 engines and will bring this very, very successful engine to China.
“The thinking is that we will build the model 2011 engine for European and American needs here in Cologne and the 2011 engines for China and Asian needs will be built there. This is a good step forward for us.
“The general trend of growth for Chi-na is still there. The expectations of two to three years ago were perhaps too overly optimistic. Currently they might be overly pessimistic. We expect a steady growth and it will certainly be the most important area in the world.
“We will certainly watch all that quite closely to ensure we install the right capacity, but we will create a produc-tion environment where we can add ad-ditional capacity if needed. This is also part of our production philosophy and our production design that we have put in here in Germany. The production we have put in here can be easily expanded — as I said it is a modular design — and we can easily expand it with the same concept. It provides us with an opportu-nity to add capacity where needed.”
Regarding the future for Deutz:“First of all, it is taking our exist-
ing technology into new projects with existing customers, as well as new customers with our Tier 3, Tier 4 final, ‘Tier 5’ engines, in addition to our new medium-duty engine platform with Volvo,” Leube said.
“Then part of our product strategy is to further provide what we call sys-tems solutions in the future. The idea is not new. If you want to have an ef-ficient machine, you not only need an efficient engine, you need an efficient powertrain. Our big customers do that systems integration or systems de-sign on their own. Many of our smaller customers don’t do it to that degree.
The focus of Deutz’s most re-cent joint venture in China in-cludes bringing production the company’s popular model 2011 diesel to the venture for the Chinese and Asian markets.
“So here, we are looking into what further engineering services we can provide for our customer base. Part of this systems approach is also thinking about the new products we can add to the engine — aftertreatment, instru-ments, telematics and so on to further this business.
“This is part of our strategy as well … moving more toward systems inte-gration, providing engineering servic-es on one side and other products on the other side.”
Will Deutz still be independent 10 years from now?
“Yes, of course,” Leube said. “We do have a globally known brand, a high-quality reputation. A reputation for premium product, excellent fuel consumption, good noise emissions, high-power density, good response, and with our new products we will fur-ther support this brand image.”
How will Deutz be different 10 years from now?
“The biggest change I see is our organization,” Leube said. “We will drive the whole organization more internationally. We will increase our R&D footprint, our production foot-print, our logistics footprint with our joint ventures.
“I do see the company much more internationally focused in 10 years than I see it today — much more global.
“Talking about the organization be-ing more global, our share of Asian sales will be much higher in the future. If you take our Deutz AG financial fig-ures today and add the figures from our existing joint ventures which are not consolidated in our balance sheet, we are already quite well balanced.
“Europe no longer remains the main region where we sell products. If you look at it that way, it is already quite well-balanced. But there is no doubt Asia will become more important for us.” dpi

Bomag Keeps Cool on Emissions Compaction equipment specialist adopts MTU diesels with specialized
cooling system for refuse compactorsBy RoBeRta PRandi
Like all global manufacturers of construction equipment, Bomag is facing a challenge when it comes to diesel en-
gines. While ever more stringent emissions levels are coming into play in much of Europe and the U.S., other regions are nowhere even close to being on the same levels, not to men-tion the myriad differences related to logistics, distribution, etc., related to operating in different countries.
As Bomag noted in its testing, new engines developed to meet EU and U.S. Environmental Protection Agency emis-sions standards are highly sensitive to water and dirt and must operate on ultralow sulfur diesel (ULSD) fuel. The availability of optimized fuels such as ULSD represents a great challenge to many countries around the globe.
Yet Bomag decided that rather than view that emissions paradox as simply a challenge, it could serve as an opportunity as well. Thus the manufacturer has already placed its
Bomag Telematic monitoring system, which is designed to enable the user to determine the machine’s fuel con-sumption at any time and analyze this in detail over weeks and months. Ac-cording to Bomag, its customers can pay off the additional outlay at the time of purchase with the savings on diesel fuel alone, in a little over two years on average.
Bomag said it would modify all of its refuse compactors with engine out-puts over 130 kW and release them into markets adopting the newest emission regulations. Current Bomag machines will still be offered on other international markets that do not have the appropriate fuel available.
Within the next six months, Bomag said all machines from 56 to 130 kW would follow suit, while those from 37 to 56 kW would follow later. dpi
first Stage 3b machines in the mar-ket. The BC 1172 RB-3 refuse com-pactor incorporates an MTU Series 500 diesel, based on the Mercedes-Benz eight-cylinder vee configura-tion OM 502 LA diesel. Bomag said it is using MTU/Mercedes engine technology for the first time and will adopt MTU Series 400 and 500 en-gines for other machines in its re-fuse compactor range.
The engines deliver power outputs up to 440 kW and are based on the commercial vehicle engines OM 460 LA and OM 502 LA from Mercedes-Benz. In particular, these engines incorporate a cooling system that has been engi-neered specifically for this application, Bomag said. The company reported that, in the course of a field analysis in the northern part of the U.S.A., fuel con-sumption for the BC 1172 RB-3 refuse compactor was reduced by as much as 16.5% compared to the previous mod-el, reducing costs by 13.3%.

Tier 4 Crawler Excavator
New Holland using cooled EGR with a DPF on new midsize machines
By Ian Cameron
New Holland will introduce what it called the industry’s first Tier 4 final compliant midsize crawler excavators
at bauma 2013.The new E75C SR and E85C MSR
excavators are powered by Isuzu AU-4LE2X engines producing 42 kW net power. Both models meet Tier 4 fi-nal emissions standards through use of cooled exhaust gas recirculation (CEGR) technology combined with a diesel oxidation catalyst (DOC) after-treatment system and do not require ac-tive regeneration of the particulate filter, New Holland said.
The company said it based its Tier 4 final solution on CEGR technology for light-duty engines below 75 kW, where the compact dimensions of the machines create a space constraint.
The two machines also incorporate
well as enhancing operator comfort, said the company.
To complete New Holland’s new crawler excavator range, the company is also unveiling three short-radius ma-chines, the E230C SR, E260C SR and E160C Blade Runner. The E230C SR and E260C SR are powered by Hino diesels rated 124 kW, while the E160C is driven by a 74 kW Mitsubishi diesel.
New Holland said all three crawler excavators meet Tier 4 interim emis-sions standards with CEGR technol-ogy and a DPF.
New Holland is also taking the wraps off a new Tier 4 interim FPT-powered W170C wheel loader for the recycling industry at bauma. dpi
a new version of the company’s Intel-ligent Total Control System (ITCS) that operates all machine functions.

The result is up to 31.4% fuel savings with variable power control, optimized engine speed and pump torque in all operating condi-tions, the company said.
Other launches at the show in-clude the L230 skid-steer loader and C238 compact track loader. Both machines use Stage 3a compliant FPT diesel engine rated 67 kW to compete in the high-end segment of the market.

EnginE control Made easier New electronic engine control panel from LOFA aims to
make things simpler for operators
LOFA Industries Inc., Roswell, Georgia, U.S.A., has an-nounced the addition of the new operator-centric control
panel to its line of electronic engine controls. The new model CP620 panel uses SAE J1939 protocol and is con-figurable to most engine manufactur-ers’ application requirements and com-patible with Euro Stage 3b/4 and EPA Tier 3, Tier 4 interim and Tier 4 final requirements, the company said.
The CP620 is designed to mini-mize operator training and confusion, especially regarding operator inputs required for Tier 4 interim and Tier 4 final engines, LOFA said, adding that the CP620 Tier 4 panel has been de-signed to assist operators in the man-agement of regeneration.
A three-position rocker switch on the panel facilitates automatic and stationary regeneration, and inhibits regeneration commands without hav-ing to navigate through display menus that could require intensive training. LOFA said the operator activates the rocker switch in response to the pan-el’s displayed emissions-related icons and/or messages.
An optional interlock rocker switch is also available in both CANbus and
password protected. The display has four pages with four gauges on each page that can be rearranged by the user. Engine J1939 generated alarms and codes are stored in the panel’s memory for diagnostics and review.
The CP620 features custom configu-ration on two levels, depending on the frequency of needed changes, security requirements, and application or cus-tomer requirements. The display pro-vides what LOFA said is user-friendly configurability and is password pro-tected. Its options include (but are not limited to): customization of 16-digital or analog gauges, unit selection (English/metric), backlight contrast, service tim-ers and language selection.
Further, with LOFA’s CANbus con-figuration kit, custom application and customer-specific parameters such as splash screens, custom functionality, and maximum engine speed settings (within ECU default limits) are eas-ily facilitated, the company said. The CANbus configuration system also provides for easy updates to firmware and allows for custom configurations to be saved and populated to multiple CP620 panels. dpi
hardwire configurations for engines requiring operator confirmation of a machine’s readiness for regeneration.
The design of the CP620 includes a corrosion-resistant enclosure with a powder coating and IP-rated com-ponents. It also has a three-point vi-bration isolation system and simple mounting bracket to facilitate multiple mounting positions/locations.
In addition, the CP620 has heavy-duty, weather-resistant switches, includ-ing a key switch and single momentary switch that adjusts the engine speed for most electronically governed engines using CANbus throttle controls. Con-nection to the engine harness is via a 21-pin Deutsch connector mounted on the bottom of the panel. Custom adapt-er harnesses are also available, the company said.
The display on the new CP620 is designed to provide a clear, concise display of J1939 diagnostic codes and emissions icons. The Tier 4 interim and Tier 4 final version of the CP620 features industry-familiar red and am-ber LED indication of alarm and/or warning conditions.

Providing The Muscle For Machines
Sweden’s Stacke Hydraulik focuses on engineered cylinders for mobile equipment
By Bo SvenSSon
Hydraulics play an important role in mobile equipment used worldwide. One of the most widely used hydraulic compo-
nents are cylinders, which provide the muscle to drive machine functions such as lifting and steering across a broad range of engine-powered equipment and vehicles. Swedish manufacturer Stacke Hydraulik AB is a specialist in hydraulic cylinder technology and said it has found growing applications from a range of manufacturers.
“You can find our cylinders in ev-erything from construction equipment, trucks and forest machinery, cranes, mining equipment and in a variety of industrial applications,” said Anders Stacke, managing director, Stacke Hydraulik AB. “Most of the products are developed in close cooperation with our customers and this way the cylinders are tailored for high stan-dards and our customers’ needs.”
With a broad program of standard hydraulic cylinders as a base, the
with a built-in linear encoder, which gives direct position feedback during the cylinder stroke. The linear sensors are built into the cylinder, a design that protects them from external damage. These types of cylinders are used in a variety of applications, particularly where there is a need to know the exact position of the cylinders, such as steer-ing cylinders, positioning cylinders and in many industrial applications.
The advantage of the linear encod-er cylinder is that there can also be an adjustable cushioning function that can be programmed into wherever it is needed in the stroke.
Cylinders with valve functions are used in a variety of areas with a need for increased safety and performance. The valve functions can be built into the cylinder or mounted directly on the cylinder to ensure that a lifted load does not fall if there is a failure in the system, such as a hose break. Com-mon types of valves are safety valves, check valves and load holding valves.
company also designs and manu-factures customer-specific solutions. “For us it is important to know how the cylinder is expected to perform and in what environment it will be used,” Stacke said. “Then we can assist in choosing the right cylinder and adjust it to a unique product for best results.
“We design and manufacture every-thing from control cylinders, telescopic cylinders and cylinders with cushion-ing, linear sensor and valve functions.”
In trucks, there is often a need for high lift heights. For this reason, the company manufactures cylinders with strokes up to 6500 mm. Hoists are often single-act-ing, either an in-the-flask sealed design or plunge configuration. Tilt, extension and outrigger cylinders are also pro-duced for these applications.
Large forklifts also need cylinders that can accommodate high lift demands, and Stacke Hydraulik manufactures cyl-inders with a maximum length of 6000 mm for such applications.
A more delicate product is a cylinder

Stacke Hydraulik de-signs and manufactures all of its products in Skill-ingaryd, Sweden. All the important steps in the manufacturing process of the cylinders, such as machining, welding, as-sembly and painting, are made in the factory. A large part of every step in the process is computer-ized and automated, us-ing advanced robotics.

Another high-technology product is cylinders with end cushioning, which Stacke said are used to achieve a softer running in the cylinder lock. The at-tenuation can be applied on the traction side, pressure side or in both directions. To provide a dampening effect, the flow of oil is decreased during the last part of the cylinder stroke, which increases the oil pressure in the chamber and slows down the cylinder movement.
Vehicle-mounted systems can be used on all types of vehicles and mobile machinery. One example is the load-ing dock on the back of a truck, where the cylinders are often placed in tight enclosures. Both single- and double-acting telescopic cylinders are suitable for these applications, Stacke said. The standard series DA250 (double-acting) offers working pressures up to 250 bar,
with diameters from 25 to 250 mm and stroke lengths from 10 to 6000 mm. Since cylinders used in these applica-tions are often exposed to a “blast ef-fect” and road salt spray, the surface of the piston rods are typically treated with a corrosion protection.
Forestry machines, which are ex-posed to extreme stresses, are an-other difficult application for hydrau-lic cylinders. Because of the remote areas the machines typically work in only a minimum of downtime is acceptable. For these applications, Stacke Hydraulik produces cylinders from its standard DA250 series with an enhanced seal development and additional mounting variants.
Construction equipment normally uses double-acting cylinders, which often operate with pressures up to

400 bar. These cylinders are de-signed to withstand many cycles, tolerate high mechanical loads and face the likelihood that the piston rods will be subject to external forc-es. Because of this, it is important that the cylinder design allows easy removal and maintenance, which can often be achieved through use of a bolted fitting. The piston rods are often induction-hardened to re-sist external impact and strain.
Mining is another area where the operating environment is harsh and cyl-inders can be exposed to high cycling and high mechanical loading. For these applications, Stacke Hydraulik offers heavy-duty cylinders with bolted-joint designs, friction welded piston rod heads and induction hardened piston rods for such services.
“We view ourselves as a strong partner in the hydraulics, a market which for Stacke Hydraulik is char-acterized by long collaborations with many well known companies in vari-ous industries,” Stacke said. “The core of Stacke Hydraulik is our design de-partment, which houses priceless ex-perience and thorough knowledge of hydraulics and mechanics.” dpi

Back In The Family Business
Magni Telescopic Handlers launching new machines to the market; new brand for veterans in material handling business
Eugenio Magni is the third gen-eration of entrepreneur in his family — and he is now head of sales in the newly founded
Magni Telescopic Handlers company. “My family looks back to a few de-cades of activity in the field of material handling, starting with granddad Pi-etro, who founded Fargh SpA in Italy in 1972 and started producing tele-scopic forklifts in 1980,” he said.
Eugenio’s father, Riccardo Magni, succeeded his father in the company business and started a cooperation with the Manitou group that lasted more than 27 years until he left his position as managing director of Manitou Costruzi-oni Industriali in 2009. In the second half of 2012, Magni created his own com-pany, Magni Telescopic Handlers, along with his sons and daughters.
Now that company will introduce its brand new vehicles at bauma 2013. The telehandlers are divided into two main ranges — the RTH range, com-posed of seven rotating telehandlers and the HTH range, composed of two heavy-duty machines for the mining and oil industry, with one additional model in development.
The RTH range covers from 4.0 to
range, Magni Telescopic Handlers has just signed a long-term agreement with JCB for the exclusive supply of their Ecomax Tier 4 interim engines.”
JCB said one of the major Ecomax benefits is low fuel consumption and the engine, which has no diesel par-ticulate filter, achieves savings of up to 10% compared to its Tier 3 counter-part, the company said.
The engines are teamed with elec-tronically controlled Bosch Rexroth hydrostatic transmissions and two os-
6.0 tonnes maximum loading capacity and from 17.50 to 29.90 m maximum lifting heights. The HTH range will ul-timately cover from 15 to 30 tonnes maximum loading capacity, with the smaller 15 tonne machine still cur-rently in the development phase.
“All these machines utilize Stage 3b compliant Mercedes-Benz engines, industrialized by MTU Friedrich-shafen, with 95, 115, 150 and 240 kW output power,” Magni said. “For Stage 4 emissions regulations in the RTH

cillating steering axles from Dana. The drivetrain is engineered to provide fast travel speed on the road — up to 40 kph — while still providing an improvement in fuel consumption of 10 to 15% over competitive systems, Magni said.
The load-sensing hydraulic circuit includes a Bosch Rexroth main vari-able displacement pump and Sauer-Danfoss’ latest SIL 2 valve system with electro-proportional control and instan-taneous spool position detection.
All the machines in Magni’s RTH rotating range are assembled on two basic chassis models that incorporate
a rigid structure designed to prevent the frame members from twisting, even when subjected to considerable stress, thereby increasing the stability of the machine.
Furthermore, the company has intro-duced a newly patented stabilizing sys-tem, which utilizes outriggers that com-bine a pivoting end and an extendable end. Both outriggers are connected to the frame ends on the same axis with-out overlapping, which allows them to retract into the frame structure, length-ening the wheelbase of the machine. This, Magni explained, improves load

capacity and facilitates the installation of Stage 4 engines, which are more bulky than earlier engines that did not require space for urea reservoirs.
Dedicated software developed by Magni controls the active dynamic stabilizing system based on the extension length measurement of each outrigger. When the machine is insufficiently stable on its four feet, the system constantly calculates the bearing capacity and adapts the load chart of the machine to its real stability requirements.
Magni Telescopic Handlers is head-quartered near Modena, Italy, in a new 6000 m2 factory with an annual pro-duction capacity of 1000 machines. The company also developed and manufactures two special machine ranges. The Boat Eagle 509 and 512 marine lifting and handling systems have 9 and 12 m lifting heights and are able to handle and store boats up to 10 m in length in dry dock. The Rickilif 13, 15 and 18 machines, which are designed to manage the produc-tion process for palm dates, from pol-lination of the trees to harvesting the dates, have 13, 15 and 18 m working heights, respectively. dpi

New Course For Comer
Powertrain system specialist’s reorganization highlighted by launch of new generation of axles, planetary drives
By RoBeRta PRandi
A visitor to Comer Industries can immediately sense that things have changed for the Italian manufacturer of powertrain
components for the global equipment markets. The company has charted a new course in nearly every aspect of its business, from supply chain to quality, from product design to manu-facturing operations.
For the company’s Planetary Drives and Axles operating unit, this has cul-minated in a completely reorganized and dedicated plant in Cavriago, near Reggio Emilia, Italy, and the launch of a new generation of axles and plane-tary drives rounding off the higher end of the company’s ranges.
Comer Industries has dedicated three years and substantial invest-ments to carrying out a bold im-provement plan, supported by Kai-zen methods with more than 1100 employees involved in Kaizen train-
applications. The plant covers an area of 15 000 m2 and employs more than 210 people.
The highlight of the facility is the new assembly line for Comer’s new generation of rigid and steering ax-les; a modern and state-of-the-art area that will allow Comer Industries to serve its global customer base with quality products and the neces-sary flexibility at the same time. A new paint shop is also going to be put in operation in the course of 2013.
The new assembly line is dedicat-ed to the new generation axles, start-ing with the S-128 model already in series production. That is being fol-lowed by the new S-228 and S-238 rigid and steering differential axles that will premiere at bauma 2013, after completion of a full program of successful customer field tests, Comer said.
The S-228 axle is available with a
ing. In the manufacturing area, the course changes have been enhanced by the Comer Production System (CPS), an integrated methodol-ogy that encourages people to sup-port daily continuous improvement, which has been introduced into all business areas.
In parallel, the company’s industrial plan has put the strategy in practice with a program of rationalization and simplification of the operating units — investments to this end have been €16 million in 2012 alone, a figure that is expected to increase in 2013 and 2014.
A glimpse of the innovation wave that has swept through the com-pany can be appreciated in the new Cavriago plant that has been trans-formed from a multifunctional site to an assembly facility fully dedicated to the axle and planetary drive plat-form for construction and industrial

chines and agricultural vehicles with gross vehicle weights up to 24 tonnes and 100 kW engine power. However, the axles’ braking systems and the capability of versions for ve-hicle suspensions with leaf and air springs, make it possible to use these axles on a variety of applications, including road-going vehicles, the company said.
Completing its product program for the heavy-duty range, Comer Industries will also introduce a new track drive series at bauma 2013. The PGRF 7003, PGRF 9003 and PGRF 11003 have peak output torques of 70 000, 90 000 and 110 000 Nm respectively. The new PG 3503 PR slew drive with a peak output torque of 35 000 Nm.
The new drives all feature three planetary stages reduc-tion and have a wide range of ratios — from 70 to 250 — to fit a number of different applications beside the typical track mobile equipment, such as winches, milling devices and drilling rigs.
All models are designed for the most common axial pis-ton motors from 90 to 160 cm3, with variable or fixed dis-placement. A SAHR brake option is available as well and so is a disconnect option, for mechanical disconnect from the hydraulic brake. dpi

A Liquid Situation
Hatz unveiling first in new liquid-cooled, common rail diesel engines, along with liquid-cooled, single-cylinder prototype
Motorenfabrik Hatz is using bauma 2013 as the launching pad for a new generation of water-cooled industrial diesel engines. The new H-series engine family of multicylinder engines will incor-
porate an electronically controlled common rail fuel system and is designed to meet stringent diesel emissions stan-dards without a diesel particulate filter.
Hatz, long recognized as a pioneer in air-cooled en-gines, will also display a liquid-cooled, single-cylinder die-sel concept.
The first model in the new H-series engine family is the H50, which will become available in early 2014. The H50 is an inline four-cylinder diesel with a displacement of 1.951 L that Hatz said is engineered to be the most compact, high-power den-sity engine in its class.
The engine will have a maximum power output of 56 kW at 2800 r/min, with a peak torque output of 240 Nm, which is available at speeds as low as 1600 r/min.
The H50 incorporates a Bosch high-pressure, common rail system that can deliver injection pressures as high as 1800 bar. This, combined with an optimized combustion chamber geometry, results in reduced PM emissions and enables the engine to meet EU Stage 3b and Tier 4 final emissions regu-lations without using a DPF.
At the same time, Hatz said the engine offers low fuel consumption — 210 g/kWh at the optimum point of the op-erating range, the company said.
With low total cost of ownership as a key design goal in the development of the new engine, the H-series diesels will have service intervals of 500 hours. This is thanks in large measure to features such as a maintenance-free hydraulic valve train adjustment and a 7.0 L oil sump.
Along with the H-series engines, Hatz will also show its 1D81 Hydro concept at bauma 2013. The prototype en-gine is based on the existing Hatz air-cooled 1D81 single- cylinder diesel engine, but incorporates a water-cooled cyl-inder and cylinder head and a compact radiator with no ex-ternal water hoses.
Even with the new liquid-cooling system, Hatz said the engine remains compact — only slightly larger than its air-cooled sibling.
Hatz said that the purpose of the prototype development is to examine the effects of water-cooled technology on en-gine performance, noise and exhaust emissions. dpi

Backhoe Taking CenTer STage
New TLB890 among the highlighted machines for Terex Construction in Munich
By Ian Cameron
The new TLB890 backhoe loader will be one of the high-lights of the 20-plus machine lineup from Terex Construc-
tion at bauma 2013 in Munich. The machine is powered by a Perkins 1104D-44TA diesel engine that in-corporates a wastegate turbocharg-er and charge-air cooling.
The engine, which meets EPA Tier 3 emissions levels, is rated 74.5 kW. It drives a Carraro transmission and a new high-pressure hydraulic sys-tem based on a Bosch Rexroth piston pump that helps deliver high breakout force on the boom, dipper and buck-et services and is key to what Terex called the machine’s “excellent pro-ductivity levels.”
Terex said the design improvements also result in impressive slew torque, which provides powerful and quick backfilling, especially when working
Terex uses a variety of engines in its German-made compact machines including Yanmar, Mitsubishi, Deutz and Perkins.
In addition, the TC10 micro excava-tor, which was launched in 2012 and is driven by a Yanmar diesel, will make its first appearance at bauma, along with the TR60 rigid truck. The TR60 has a new integrated dashboard designed to provide more machine feedback capa-bility and production data to help cus-tomers manage fleets better, Terex said.
The truck also has a new modular rear-brake retardation system that al-lows the operator to modulate pres-sure in six stages instead of two, al-lowing for a controlled descent, the company said. dpi
on cross slopes. The curved boom design also allows trucks to be posi-tioned closer to the machine for short loading cycles, the company said.
Another machine under the spot-light at the Terex stand is the Fuchs MHL350 E material handler. Powered by a Deutz 6.1 L6 diesel rated 160 kW, it incorporates a Linde transmis-sion and Linde hydraulic system with load limit control.
For the first time, the German-man-ufactured Terex compact machines will be exhibited with Tier 4 interim/Stage 3b compliant engines. Visitors to the Terex stand will be able to see the Deutz-powered TW85 wheeled exca-vator and the TL120, Perkins-powered wheel loader’s new ergonomically de-signed operator interface, which has more electronic functions including new display and control functions to increase operator productivity.

Targeting medium-duty mobile ma-chines, the first orbital motor and steer-ing unit in the new V-Series will also debut at bauma.
The first V-Series orbital motor is the VMP. Covering a displacement range of 50 to 315 cm3 and with a pressure capability up to 140 bar, the VMP offers the same space-saving and features as the Sauer-Danfoss O-Series orbital mo-tors and is lighter, the company said.
It added that by focusing on hydrau-lic work functions in the medium-duty range, Sauer-Danfoss has given the VMP the durability to last the lifetime of the overall machine. The result, Sauer-Danfoss said, is an optimized motor that reduces the total system cost of the entire hydraulic system.
“The VMP has been designed with less demanding or infrequent tasks in mind,” said Knud Meldgaard, Sauer-Danfoss product marketing manager. “That makes it of particular interest to manufacturers of seasonal machines, such as harvesters, and for medium-duty tasks, such as driving the con-veyors on agricultural equipment and the brushes on sweepers.”
Other application opportunities in-clude cranes, aerial lifts, seeders and spreaders. The VMP incorporates a high-pressure shaft seal, which elimi-nates the need to connect a drain line to the tank in many applications, sig-nificantly reducing installation costs, Sauer-Danfoss said.
Other products at Munich include the Plus+1 controllers, the JS7000 joystick, the PVG16 valve, the new PVE-EX electrohydraulic actuator designed for mining and offshore applications, the EMD speed sensor and the H1 family of pumps and motors. dpi

The Korean-built mini excavator has been fitted with a long life plastic air filter for easier maintenance and the company added that the long service life of hydraulic filters (1000 hours) and hydraulic oil (5000 hours) helps reduce operating costs. Lubrication intervals have been also increased from 50 to 250 operating hours due to the use of self-lubricating bushings, Hyundai said.
The R25Z-9A has two travel speeds — 2.5 and 4.5 kph — which Hyundai said enables it to be used more slowly in a delicate work environment as well as be driven at higher speed to the work site.

GivinG powertrains a Boost
Spicer PowerBoost hydraulic hybrid technology offers significant fuel economy improvements in broad range of equipment applications
By RoBeRta PRandi
Dana has developed a new line of integrated hydraulic hybrid powertrain concepts for the off-highway market that will be
introduced at bauma 2013. The Spicer PowerBoost system is the result of a three-year development program at Dana’s advanced technology centers in Belgium, Italy, and the U.S.A.
The manufacturer explained that Spicer PowerBoost is a system for se-ries or parallel hybrid configurations that supplements all types of transmission architectures and needs little adaptation work to fit into existing vehicle designs.
Ettore Cosoli, head of the off-highway and specialty vehicle hybrid program at Dana Holding Corp. in Arco, Italy, said Spicer PowerBoost technology is ideally suited to applications that have frequent, intense bursts of accel-eration, deceleration, lifting and low-ering during cyclic maneuvering that support the recuperation of working and braking energy. These applica-tions include construction equipment, material handling machines and on- highway vocational vehicles, all of which will be the initial target markets for the technology.
The key function of the Spicer Power-Boost design is the capture of kinetic
gine at or slightly above the EPA Tier 4 final or Euro Stage 3b emissions threshold of 56 kW. The PowerBoost technology could allow a manufac-turer to select a smaller engine for its machine, potentially avoiding issues surrounding exhaust aftertreatement.
The Spicer PowerBoost system can also be configured to minimize idling by shutting down the diesel engine and uti-lizing stored energy captured in the ac-cumulators to operate vehicle functions that consume low amounts of energy, such as inching, light working condi-tions and low travel speeds. Vehicle productivity could also be improved by shortening the length of time to com-plete a “Y” cycle, reducing the number of fuel stops and extending the period for brake maintenance, thanks to the dynamic braking effects of recuperation.
The Spicer PowerBoost will be fea-tured at bauma 2013 on the Dana stand as part of a compact 5.5 to 9 tonne front-end loader drive. In the second quarter of 2013, functional prototypes will be available for field-testing by OEMs, Dana said. dpi
energy from the drivetrain and working hydraulics, which is recovered and used to help power vehicle functions. Dana calculated that Spicer PowerBoost technology could reduce fuel consump-tion in a typical front-end loader by 20 to 40% compared to conventional drive-train concepts. The results, Dana said, were dependent on the specific applica-tion and the vehicle duty cycle.
Cosoli said that at the core of Spicer PowerBoost is an advanced energy-management system that evaluates the levels of power needed in the entire vehicle system, predicts operating demands, and determines the most efficient means of opera-tion. Hydrostatic energy is captured in an accumulator from the pow-ertrain during low power operation of the engine and also recuperated from the braking and work circuits.
“This smart use of hydrostatic en-ergy can help reduce total owning and operating costs,” Cosoli said. “In ad-dition to that, the Spicer PowerBoost offers a great potential for the employ-ment of a downsized engine.”
The chance to reduce engine size for power outputs from 55 to 250 kW will be especially interesting for appli-cations that currently require an en-

Caterpillar to have more than 70 machines at bauma, including new hybrid excavator and roadbuilding machines
By Ian Cameron
It is appropriate that for the biggest show in the equipment industry, Cat-erpillar will offer one of its biggest machine displays ever, totaling more
than 70 machines, including three new paving products, at bauma in Munich.
In all, Cat will have three different ex-hibit areas totaling more 12000 m3, with its main indoor stand in hall B6 encom-passing more than 50 machines.
Among the highlights is the new Cat 336E H hybrid excavator (see March Diesel Progress International), and three new models in the Cat paving
cavators (the Cat 302.2D, 302.4D and the compact radius 301.7D and 308E2), the 444F equal size tire backhoe loader and the D6K2 track-type tractor. Also on site will be the recently introduced 318E hydraulic excavator and M313D wheeled excavator, the 120M2 AWD motor grader and the 91 tonne capacity 777G off-highway truck.

Engineers and purchasing managers worldwide have found their way through a maze of regulations — emissions and
operator safety standards, the Restrictions of Hazardous Substances (RoHS) directives, etc. — that have changed the course of supply chains and even the physical composition of the products themselves.
U.S. disclose the presence of certain minerals used in their products and whether they were sourced from mines in the Democratic Republic of Congo (DRC), Africa. Many mines in the mineralrich nation are controlled by rebels or corrupt armies that have done terrible things to the people of Congo. While the worldwide popularity of electronic technology — which utilizes the ores from that region — should be a boon to Congolese mine operators and villagers, much of the money from the mineral trade reportedly never reaches the populace. Instead it’s often used to build a weapons arsenal. Section 1502 seeks to disarm DRC’s violence by restricting the market for “minerals of conflict.”
Although there is a tendency to group REACH and Conflict Minerals together, they are two different regulations with entirely different impacts.
“I believe Conflict Minerals is going to be very important for North American manufacturers,” said Mike Pankonin, senior director, Technical & Safety Services, Association of Equipment Manufacturers (AEM), Milwaukee, Wisconsin, U.S.A. “For manufacturers that are exporting to Europe, REACH is going to be very important, and they will need to develop a plan for compliance.”
But over the past several years, two new directives from the European Union and the United States could very well move the complexity of today’s global business environment to entirely new levels.
From the EU, there is the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) directive. And in the U.S., there is a new law that passed as part of the DoddFrank Wall Street Reform and Consumer Protection Act in 2010.
Much like the RoHS and Waste Electrical and Electronic Equipment (WEEE) material directives, companies selling into the EU must also comply with REACH, which seeks to protect human health and the environment by identifying dangerous chemicals used in all types of products. Lacking proper documentation could mean that whole goods may not be permitted to leave the ship at a European port of entry.
DoddFrank’s Section 1502 requires that publicly traded companies in the

Following the passage of the Dodd-Frank Act, the U.S. Securities and Ex-change Commission (SEC) adopted its specific rules concerning Conflict Min-erals on August 22, 2012. It includes a disclosure requirement that stipulates companies must perform supply chain due diligence in order to determine whether their products contain miner-als from the DRC or adjoining countries. Their findings must then be reported to the SEC and the public. The act does not ban the use of the minerals, nor does it penalize manufacturers.
Companies are required to file their reports for the same period — a cal-endar year — regardless of when their fiscal year ends. The first Conflict Min-eral disclosure report is due on May 31, 2014 (for the 2013 calendar year) and annually on May 31 thereafter.
This means companies need to be working on their Conflict Minerals re-port for the SEC right now. Decision makers at equipment OEMs will prob-ably shortly need to become familiar with who their smelter is, along with what mine supplies the ore known as wolframite.
The SEC identifies wolframite, along with cassiterite, columbite-tantalite, gold and their derivatives as minerals of conflict. Cassiterite is an ore that’s used to produce tin, a material found in alloys, plating and solders for elec-tronic circuits. Columbite-tantalite (or coltan) is the ore from which tantalum is extracted. Tantalum is used as an alloy as well as in electronic compo-nents — tantalum capacitors are com-
mon. Gold, due to its superior electric conductivity and corrosion resistance, is also found in electronics. Wolframite is the principle ore of tungsten, used in wires and contacts in lights, electron-ics, heating and welding applications.
The SEC provision also reserves the right to add new minerals, stating that the regulation can relate to “any other minerals or their derivatives determined by the U.S. secretary of state to be financing conflict.” In other words, stay tuned.
The U.S. isn’t alone in its effort to stop the carnage occurring in the DRC. The EU is considering similar measures, as is Canada.
As part of the directive, publicly traded companies must demonstrate a good faith effort to identify where the minerals are coming from. “This will be a challenge,” Pankonin said. “A large company may be using dozens if not hundreds of suppliers, and those sup-pliers are going be collecting this data for other customers at the same time.”
Supply chain due diligence means researching the chain all the way to a smelter. From there, filing companies and their suppliers must determine from what mine that smelter has ac-quired its minerals. The Congolese army has taken control of some “clean” mines in the DRC.
“Companies must go back through their entire supply chain, sometimes 10 layers deep,” Pankonin said. “It’s a new process manufacturers must em-brace — one for which they must be able to demonstrate reliability and re-peatability in finding the source of the material they’re using.”
The chance that the purchase of a new mobile phone could help fund a humanitarian nightmare in central Afri-ca has brought the violence to the con-sciousness of the general public. The problem certainly isn’t limited to con-sumer electronics. Manufacturers of farm and construction equipment “must also be able to eventually document where their materials come from,” Pan-konin said. “The larger the company and the wider their supplier base, the
more important and complex this job becomes. OEMs are now sending out inquiries to their supply base to initiate a process to collect that information.”
Member companies in the U.S.-based Automotive Industry Action Group (AIAG) include car and mobile equipment OEMs and suppliers of all sizes. The group started early to find a common solution for supply chain transparency. A Conflict Minerals group composed of member companies such as Bosch, Navistar and Dana has been meeting every two weeks since 2010.
“The member companies realize they all have some degree of exposure in this legislation,” said Tanya Bolden, development manager, Corporate Re-sponsibility Program, AIAG, Southfield, Michigan, U.S.A. “Even if they don’t report to the SEC or are not publicly traded, many of their customers are.”
According to Bolden, the electron-ics industry was further along this path due to the use of the specific minerals in its products and had a good tem-plate for collecting data. The Electronic Industry Citizenship Coalition (EICC) and the Global e-Sustainability Initia-tive (GeSI) developed the EICC-GeSI Conflict-Free Smelter assessment pro-gram system for data collection.
The Conflict-Free Smelter program audits smelters worldwide and as-signs a status that can be used by downstream manufacturers. Smelter information is the key to creating the Conflict Minerals declaration.
AIAG and its Conflict Minerals group have collaborated with supply chain software developer iPoint-systems GmbH, Reutlingen, Germany, in the development of a software tool to help streamline the process. iPCMP (iPoint Conflict Minerals Platform) is a web-based data management tool that AIAG said will help supply chain partic-ipants in all industries identify whether their products contain these minerals and thus meet due diligence require-ments. EICC-GeSI also provided input in the project.
“The Conflict Minerals requirements are generally viewed as quite oner-

ous,” said Thomas Bley, project manager, Sustainability, iPoint. “Companies are struggling to find strategies that will enable them to reach down into their supply chain across several tiers to get the data. In most cases, the OEM has no idea where the minerals originate.
“There can also be an issue of secrecy among suppliers. It may not be possible for the OEM to reach down to the third tier and get this information.”
The iPCMP software enables companies to send invitations to all suppliers, allowing them to answer requests efficiently, Bley said. “A large OEM will send a request to a Tier 1 supplier to collect the declaration from their suppliers, but it may be a Tier 3 supplier that has access to smelter information and source minerals,” he said. “They’ll create a declaration and send it to the Tier 1 supplier, which will roll it up with others and send the Conflict Mineral declaration to the OEM.”
“In the time since Dodd-Frank passed, many companies have worked hard to understand what is required,” Bolden said. Many suppliers have taken a proactive approach, pro-viding information about their minerals strategy online, often under “sustainability” or “investor” headings.
“Kemet’s tantalum capacitors are conflict-free,” said Daniel F. Persico, vice president of Special Projects at Kemet Corp., a Greenville, South Carolina, U.S.A., manufacturer of tanta-lum capacitors. “As the world’s largest user of tantalum, Kemet took an early leadership position in the industry on the issue of obtaining certified conflict-free minerals.

of life for the people of the DRC and a more stable supply of conflict-free ca-pacitors for our customers.”
Other industry groups are also in-volved. The Tin Supply Chain Initiative (iTSCi) is a project run by England-based International Tin Research Institute (ITRI) that helps companies from the mine to the smelter establish processes necessary to perform due diligence at a practical level. iTSCi of-fers mineral chain information in keep-ing with the requirements of the EICC-GeSI Conflict-Free Smelter program to help companies report on their due diligence efforts.
AEM has also “brought its members together to work toward meeting these types of regulations,” Pankonin said. The danger when it comes to per-forming due diligence would be that each manufacturer develops a unique supplier form, saddling downstream companies with the unenviable task of filling out hundreds of different forms.
“Many small companies can be challenged in terms of the time they need to spend on compliance,” Pan-konin said. “AEM is proposing to ad-dress these challenges as an industry as opposed to having each company work on its own.”
“While there is no financial penalty, companies have to publicly report if the material they are buying may have helped fund violence in the DRC,” said Dick Christensen, director for iPoint’s U.S.-based Sales Midwest office. “Competitors that have done their due diligence will have a field day over those who fail to file with the SEC. Those that have done their due diligence will have a
great competitive advantage over those who have not, or are slow to start.”
Bolden recommended that these tasks be made a “coordinated internal effort, not just the job of the purchasing department. We encourage them to in-clude engineers, material managers and legal staff. And that’s not even talking about the executive suite, as the CFO must sign SEC reports. Cross-functional meetings must be held for companies to begin to get at these issues.”
“The ultimate goal is to drive compli-ance into product development, which is very important,” Christensen said. “When engineers design an engine they are charged with designing one with a particular output and size. Now they also must ensure the components they’re spec’ing are free of conflict minerals. And if the engine is going to be sold in Italy, they must also have an efficient way to determine if it’s RoHS compliant and REACH reportable.”
REACH is a chemical regulation. EC 1907/2006 went into force in June 2007 and is to be phased in over 11 years, after which thousands of
chemicals will have been registered with the European Chemicals Agency (ECHA) in Helsinki, Finland. The di-rective includes a list of Substances of Very High Concern (SVHC), material that has been identified as hazardous to humans or the environment.
For example, the ECHA recently rec-ommended that formaldehyde, used as a hardener in epoxy resins, be placed on the SVHC list because it’s a carcino-gen. If and when the chemical gets put on the SVHC list, it becomes a candi-date for even further review and can find its way to the authorized use-only list.
At the beginning of 2013, there were more than 130 SVHC substances list-ed and that number is likely to grow steadily. This will require manufacturing companies to track an expanding num-ber of substances in their products.
“The Conflict Minerals regulation is a legal and financially driven initia-tive, while RoHS and REACH are EU substance-control directives and are more business-driven initiatives,” Chris-tensen said. “RoHS said ‘thou shall not use lead in solder,’ for example. With REACH you may use cadmium paint, but you ‘shall tell the customer you’re using it,’ and pay for the authorization to do so if the substance is included in the ever-expanding authorization list, which now includes 14 substances.”
The regulation requires that all sub-stances manufactured or imported into the EU on their own and in products be registered when certain criteria are met. Under REACH, substances man-ufactured or imported on their own or

in mixtures, as well as substances intended to be released from articles, need to be registered based on hazard clas-sifications and annual volume.
The registration of a substance is complex, requiring sig-nificant effort on the part of manufacturers and importers. It requires an understanding of how chemical substances are handled throughout their life cycle, and for hazardous chem-icals a risk assessment is required. Manufacturers and im-porters must register the information with the ECHA, which is building a public database for the hazard information.
REACH applies to legal entities established in the EU. Com-panies established outside the EU are not bound by its obliga-tions, even if their products are exported there. In that case, the responsibility for fulfilling the requirements lies with im-porters established in the EU. Those importers will likely look to their non-EU suppliers for the information required to fulfil regulatory obligations.
“REACH rules clearly state that if there’s no data, there’s no market,” Christensen said. “You don’t get to pay a fine and sell the equipment anyway — it simply won’t get unloaded without the proper documentation and declaration.
“For longer-lived goods such as construction equipment, compliance may be a little easier. It’s consumables such as shoes and phones that may end up in a landfill or incinera-tor that the ECHA is most worried about.”
For SVHC chemicals, a threshold of 0.1% wt/wt is the limit of the total of each product for an entire year; if the substance is below 0.1% wt/wt the obligation does not apply. Suppliers must inform their customers about the use of SVHC in their products and OEMs must report that to its customers.
In a January 2013 statement to a customer, Axiomatic Tech-nologies Corp., an electronics specialist with operations in Mississauga, Ontario, Canada, and Lempäälä, Finland, wrote that it “has reviewed all chemistries used in the manufacturing of [the products in question] and no SVHC (Substance of Very High Concern) are used or added in our processes.
“We do not supply articles containing substances on the REACH SVHC candidate list in a concentration above 0.1% wt/wt. When updated candidate lists are published by the ECHA (European Chemicals Agency), we will review the process chemistries of our articles to identify any parts con-taining SVHC. Any articles with content above 0.1% wt/wt will be reported and customers receiving articles containing SVHC will be informed through e-mail.
“We have begun to engage our suppliers to seek formal assurance of their intention to comply with the requirements of REACH for substances they supply to us, so that these substances will remain available to use for use in the future.”
“Directives such as REACH and Conflict Minerals may re-quire some companies to add staff in order to comply with all of the requirements,” AEM’s Pankonin said. “We’ve seen a bow wave of regulations and some of them are quite oner-ous. I don’t think you are going to see that wave slow down — in fact it seems to be accelerating.” dpi

Many self-propelled construc-tion machines use hydro-static transmissions instead of mechanical drives. This
means it is necessary to employ spe-cific hydraulic motors and a great va-riety of wheel drive hydraulic motors are available today.
In order to do a correct selection of the most suitable wheel drive, it is necessary to make some basic calcu-lations and considerations, which are reported here in synthesis.
First, we need to know the neces-sary traction force:
F : F = (W x R x 9.81) : n(where F stands for Newton (N); W
stands for the weight of vehicle (Kg); R stands for the slope angle (°) or trac-tion resistance (%); and n stands for the number of drive wheels).
Secondly, knowing the necessary
necessary displacement of the wheel drive motor:
Q = (T x 62.83) : p(where Q = cm3/rev; T = Nm; and P
= working pressure)The next step is to consider the
load that must be carried by the wheel drive unit, and considering the known data of pressure, torque and speed we can start to select the wheel motor suitable for our application. Here it can be of help to consult catalog indica-tions of specific torque, which is the necessary torque in Nm divided by the working pressure, thus: Nm/bar.
At this point, other considerations must be pondered such as:
1. Do we need a special hub for the rim? Wheel rims nowadays are mostly standardized and many wheel drive motors can be supplied with a suitable hub, which is directly assembled onto the shaft of the hydraulic motor.
2. Do we need a braking system for the wheel drive? If the system works in an open loop, according to security standards, we need a dynamic brake and a parking brake. In closed-loop configurations, usually only a parking brake is necessary. The brakes can be of different design: a drum or disc brake can be dynamically actuated by a positive pressure actuator (foot pedal), and in addition it can be actu-ated for parking, mostly by a flexible cable. A negative disc brake instead is a purely parking brake and closes automatically, when no pressure is applied in the drive system.
traction force, it is possible to calcu-late the torque (T), which is necessary to move the vehicle:
T = (F x d) : 2(where T stands for Nm; F stands
for the traction force = N; and d stands for the external diameter of the wheel in meters)
Remember to consider the number of drive wheels. For operations on nor-mal ground, two-wheel drives are often sufficient. For off-road applications, four or more units may be needed.
The next step is to calculate the run-ning speed of the drive wheel — and so of the hydraulic motor — related to the required driving speed:
V = 3.14 x d x n(where V = m/min; d stands for the
external diameter of the wheel (m); and n is the wheel speed).
Now we can establish the neces-sary power:
P = (T x n) : 955(where P = kW; T = Nm; and N = rpm)Having established the working
pressure of the hydraulic drive sys-tem, it is now possible to calculate the

3. Do we need a high travel speed when transferring the machine from one place to another, and a low speed when operating? This can mean that we need a two-speed wheel drive: high speed/low torque when driving on road, and low speed/high torque when working on the construction site. More sophisticated machines are often equipped with variable displace-ment hydraulic motors of variable dis-placement, where speed and torque are automatically regulated according to the operating requirements.
4. Does the hydraulic motor per-form the necessary torque at oper-ating speed? Quite often not, so the hydraulic motor must be combined with a wheel drive gearbox, usually a planetary. Planetary wheel drive gear-boxes can carry high loads and can have an integrated negative brake. The wheel drive gearboxes can be of design to assemble semi-integrated hydraulic motors, so the wheel drive becomes very compact.
5. Will it be necessary to pull the ma-chine? Over short distances only (some meters) in case of a breakdown, or over long distances?This is an important is-sue because it may be necessary to have to declutch of the hydraulic motor, or a freewheeling capability.
Finally, we can proceed to consider the different types of hydraulic motors, starting with gear motors. These were used in the past also on wheel drives, but then replaced by other designs. Gear motors have a low efficiency

when working at less than 700 r/min. Therefore their starting torque is also very low and their working pressure is limited, mostly to 250 bar. We can say that gear motors are not generally suitable for wheel drive applications.
Vane motors have similar charac-teristics to those of the gear motors,
while pressure is even more limited. Thus they are also not suitable for wheel drives.
Orbit motors are very common on smaller machines, like compaction rollers up to 2.5 tonnes, wheel load-ers, skid-steer loaders and aerial work
Small loaders and other types of compact construction equipment are common appli-cations for hydraulic wheel drives through a hydrostatic transmission. The solution, how-ever, is employed by a wide range of mobile machinery with two- or four-wheel drives and different degrees of sophistication.

platforms. As wheel type designs, they come with strong shaft bearings and with taper or spline shafts, suitable for the assembly on common wheel hubs. These motors are also avail-able with parking brakes and/or drum brakes. The “short” motors, combined with negative disc brakes, offer a com-pact design and low weight. Some are available also with two-speed selec-tion and others with declutch function.
The main range of orbit type wheel motors includes models from the smallest (25 cm3/rev, a speed range between 25 and 1600 r/min and a specific torque of 0.33 Nm) to the big-gest (800 cm3/rev, a speed range from 10 to 250 r/min and a specific torque of 11.5 Nm). As the torque is relatively low, orbit motors are often combined with planetary gearboxes with one- or two-speed reductions. The efficiency of orbit motors, at low speed (less than 25 r/min) is bad, so the addition of a planetary gearbox can greatly improve efficiency.
Axial piston motors are very common on wheel drives. They are high-speed motors, so they need to be combined with planetary gearboxes. They offer very high operating pressure, usually 350 to 400 bar, some even more. Axial piston motors can have constant dis-placement, two-speed displacement or variable displacement, so they are very flexible and offer the ideal solution. The planetary wheel drive gearboxes can
sions are suitable for continuous high speed up to 700 r/min. This shows how radial piston wheel motors are able to move construction machines without the need of a planetary gear-box or if more torque and less speed is required, a single stage reduction planetary gearbox is enough.
The design of radial piston motors is relatively simple, so the motors are robust and reliable for long service. Thus, more and more hydraulic drives are developed with radial piston mo-tors, mainly for off-road applications with four-wheel drive on machines such as diggers, drill rigs, rough-ter-rain cranes, and forest machines.
As a final note, let’s look at cost. For smaller machines certainly the orbit wheel motors, eventually with planetary wheel drive gearboxes, are the most convenient solution. Mostly, this kind of machinery also does not require the maximum torque at very low speed.
Axial piston motors combined with planetary gearboxes are costly, especially if with variable displace-ment motors. However the operating features with axial piston motors are excellent, which gives them an edge with high-technology machinery.
Wheel drive radial piston motors are becoming more appreciated, mainly for the versions with constant displacement, because they offer easy installation and control at a com-petitive price. dpi

Radial piston motors have gained popularity for wheel drive applications, mainly thanks to the in-troduction of variable displacement variants and a generally more compact and lighter design. Shown here is a single-stage wheel drive gearbox with integrated radial piston motor.
be with or without brake and mostly also with mechanical de-clutch function for freewheeling.The axial piston motors are
available from the smallest dis-placements of 5 cm3/rev — with a speed range recommended between 600 and 8000 r/min, and specific torque of 0.076 Nm/bar — to the larg-est model with 1000 cm3/rev displace-ment, a speed range between 300 and 1600 r/min and a specific torque of 15.9 Nm/bar. The efficiency is low at speeds lower than recommended, so the gearbox is a must when us-ing these motors on wheel drives. These gearboxes must have two- or three-stage reductions. The big ad-vantage is that these motors can operate also with very high speeds, and this is important for machines with frequent travelling.
Radial piston wheel motors are commonly considered high-torque/low-speed motors, and they lost im-portance in the recent years because of the heavy and voluminous con-struction and inflexibility of functions, when only fixed displacement mod-els were available. In the meantime, this situation is completely changed, as radial piston motors today are available in compact designs with less weight, with two-speed options and also with electronically con-trolled variable displacement. They can be typical wheel drive motors, with wheel hub, drum brake, parking brake and freewheeling option while maintaining the excellent character-istics of maximum torque available over a wide range of speed.

Valmova, a member of the Sauer-Danfoss Group, has launched a new line of hydrau-lic valves for mobile equipment
applications. The Brazilian company said the ECO Platform valves are designed to provide improved perfor-mance with zero leakage ports and check valve functionality.
The valves are available in three standard flow ratings — 40, 80 and 130 L/min — in open-center, proportional and load-sensing configurations.
Besides Brazil, where it maintains a headquarters in Caxias do Sul, Rio Grande do Sul state, Valmova also has a plant in India. “We have been in Brazil since 1974, producing direction-
al control valves (DCV stack valves), brakes and customized monoblock valves,” said Rinaldo Fernandes, Val-mova’s general manager. “We have our own sales organization, as well as a large number of distributors all over Brazil and South America.”
The Brazilian operation manufac-tures all three sizes of the ECO range, along with monoblocks for the agri-cultural market. In India, the company manufactures cylinders and brake valves and Fernandes said, “we also plan to produce in the near future the ECO platform (ECO 40/80) in India.”
Caxias do Sul’s facility has currently 50% of capacity for the external mar-ket — exporting to the United States, Mexico, Germany, China and all of South America — with its biggest ex-port markets in Argentina and Chile. The other 50% of capacity is dedicat-
ed to local market in Brazil. The Brazil-ian factory has design control for new product development.
The Valmova operations cover a to-tal area of 12 000 m2, with 8500 m2 dedicated to production. Fernandes said it is the only production site in Caxias do Sul to have 100% of its manufacturing area within a controlled temperature system (air conditioning). “Since the tolerances for that products are very strict (metal/metal sealing), it makes a big difference at application,” he said. The company has 190 em-ployees in Brazil and 30 in India.
“We serve all mobile markets, es pe-cially the agriculture, material han-dling, cranes, construction, road truck, sugar cane, among others,” Fernandes said. “The company’s vision is ‘to be your local partner providing valves with more value.”

“The name Valmova comes from that vision. Our value proposition is based in application knowledge, compatible technology and features at affordable price as well as cost effectiveness through operational excellence.
“We already have load sensing appli-cations covered in the flow of 80 L/min. By the last quarter of 2013, we will be introducing the 40 and 130 L/min flows. The 40 L/min flow is something new for the Brazilian market. This small valve will be simultaneously launched in Brazil and India. Valmo-va India is developing cylinders and valves for brakes. Our intention is also trade these products in Brazil.”
Fernandes said that Valmova oper-ates using lean production methods, “and due to that, we are flexible in ramping it up or down.
“Today in stackable valves, we have a month’s capacity of 13 000 stacks. For special monoblocks, we are producing today approximately 10 000 pieces per month, 90% for export. On other valves and acces-sories, we have total monthly capac-ity of 15 000 pieces. Due to our lean manufacturing system, this capac-ity is managed and adjusted as de-mand’s variation.”
Volvo On A Roll In The RegionVolvo said that it is off to a good
start in Brazil for 2013 and it follows the third-best year in the company’s history in the region.
Afrânio Chueire, president, Latin America Sales Region, Volvo Construc-tion Equipment, said 2012 was a good year. “The market confirmed our growth expectation,” Chueire said. “It was also our third consecutive year of sales above 4000 units in Latin America.”
Based in Curitiba, Paraná State, and with a plant in Pederneiras, São Paulo State, Volvo sold 4244 machines in 2012. Exports to other Latin Ameri-can countries reached 1380 units in the period. Brazil represented 67% of the brand’s sales, with 2864 machines sold, the company reported.
Volvo Construction Equipment has
also started the process of manufac-turing backhoes in Brazil. The compa-ny is transferring its Tultitlán, Mexico, production line to Pederneiras, where it manufactures other equipment. “From this plant, we will manufac-ture the backhoes to feed Brazil and Latin American countries, the United
States, Canada and other markets,” Chueire said.
In a first stage, R$20 million (US$10 million) is being invested in the line. Following the move, only Brazil and Poland will build the machines. In Pederneiras, Volvo will manufacture

the BL60B and BL70B backhoes, which the company said are most popular in Latin and North America.
Volvo has also launched its 35 ton L250G loader in Bra-zil. “The L250G is a robust machine, destined for severe tasks,” Chueire said. The machine is positioned between the L220G and the L350F loaders. Volvo also announced

JLG Opens Renovated Distribution Center
JLG Industries Inc., an Oshkosh Corp. company and a global manufacturer of aerial work platforms and telescopic material han-dlers, recently debuted its newly renovated distribution center in Indaiatuba, Brazil.
“The investment JLG has made in the Indaiatuba dis-tribution center underscores the company’s ongoing com-mitment to Latin America,” said Tim Morris, JLG Industries senior vice president of sales, market development and customer support – Americas. “We are now better posi-tioned to support our customers as they take advantage of the many growth opportunities that are transforming Latin American into such an attractive and important market.”
“The distribution center also demonstrates, in a very concrete way, JLG’s commitment to Brazil and the local Indaiatuba economy,” said Marcio Cardoso, JLG Indus-tries vice president of sales and aftermarket – South America. “As Brazil prepares to host the 2014 World Cup and 2016 Olympic Games, we are anticipating tremen-dous infrastructure improvements in the region. We have increased our workforce in Indaiatuba by 40%.”
The 11 200 m2 facility includes a renovated warehouse that accommodates a significantly larger parts inventory. Accessing those parts is much easier, thanks to a unique selection system, said JLG.
“JLG is the first company in Brazil to deploy the shuttle order picking solution in a distribution facility,” said Donnell Mata, JLG Industries director of product support – Latin America. “This cutting-edge technology supports efficient business operations by expediting the picking process and enabling our employees to fill orders at a significantly in-creased speed. At the same time, our increased parts in-ventory contributes to improved fill rates for our customers.”
According to Mata, improved fill rates mean less downtime on the job site. “And because JLG can provide more of what our customers need from a single, in-country source, they no longer need to import equipment and parts on their own, sav-ing time and the extra costs associated with the importation process,” Mata said. “Our focus is to provide our customers with a life-cycle solution — a solution that gives them not only the products they need, but also the service to support those products in the field.” dpi

Following the election of the new Communist Party leadership in November, China’s construction equipment industry began entertaining hopes that economic growth could be bolstered by the new
policies that might be implemented by the new leaders. In mid-December, the new central committee held its annual economic conference and set the tone for economic policy, although the transition of the state government will not be completed until its reelection this spring.
The conference indicated that domestic demand should

be expanded in order to sustain healthy economic growth, despite the slowing down of foreign trade, through stress-ing the importance of consumer demand and investment. While the targeted gross domestic product rate of growth was not specified at that time (as a number of economists had expected), there was the feeling that it should not be lower than the 2012 level, when it ranged between 7.5 and 8%. The government’s official forecast pegged growth at 7.5%. That’s the first time since 2005 that the government’s target has been below 8%.
The central committee conference said that the existing proactive fiscal policy and sound monetary policy should be continued and that the total scale of financing should in-crease by an “appropriate” margin. Nongovernment invest-ment is encouraged, and public spending on infrastructure development intensified with the target to improve peoples’ livelihoods, while the duplication of construction projects was to be avoided. Financial risks were also to be con-trolled very carefully, the conference concluded.
To stimulate domestic demand, the process of urbaniza-tion was given a priority, something that requires more of a balanced development among cities and townships at different levels, with a greater emphasis on improving the urban environment. It is believed that this should stimulate urban construction investment.

Will the industry recover in the short term? Even though the market might grow to meet new construction activity, excess production capacity will undoubtedly result in fierce and undisciplined competition. Despite the turbulence in demand and the deterioration of companies’ financial condition, the sector is still seeing the entry of new manufacturers. Indeed,
many companies have no idea about how to become profitable, as their policy is to rely on the support of their local government and impress out-side investors with an unrealistic view of their potential.
This is not sustainable in the long run, and highlights the weak condi-tions of the industry as it is currently structured. dpi

The country’s investment into urban utilities amounted to RMB1393.4 bil-lion in 2011, a year-on-year growth of 4%. This, it should be remembered, is much lower than the growth rate of to-tal fixed asset investment (FAI) during the same period.
Although the acceleration of eco-nomic growth is not a definite goal of the new economic policy, investment is likely to be increased. The real growth of FAI bottomed out at 16.1% in 2011 and recovered to 18.8% in the first three quarters of 2012, but this is still thought to be lower than the level needed for driving ahead economic growth.
The construction equipment indus-try should not be too optimistic about achieving a rapid recovery of new ma-chine sales, given the large volume of new machines available in stock and the uncertain progress of the implemen-tation of any new government policies. But what has been announced has generally been positively received by the industry, which has resulted in an improvement in market confidence and the financial environment.
The accompanying table shows the combined third quarter results of the 11 manufacturers that are quot-ed on the Shanghai and Shenzhen stock exchanges.
These companies — a list that includes Changlin, LiuGong, NHL, Sany HI, SCMC, Shantui, Sunward, XCMG and Zoomlion — have seen sales fluctuate significantly over the last three years, and at the end of September 2012 their average oper-ating margin has showed a decline on a year-on-year basis. Their receiv-ables account is more than twice the amount of two years ago and invento-ries remain worryingly high.
In 2011-12, most companies suf-fered from negative cash flow and their investments resulted in a net outflow of cash. At the same time, they have found it increasingly difficult indeed to attract outside investment. Although some of the leading compa-nies have done well, the industry as a whole is now under great pressure to perform as well as it would like.

Scania showing engines, trucks, gen-sets and mining equipment in Munich
By Ian Cameron
There may be exhibitors at bau-ma 2013 that take up more floor space than Scania. But it would be hard to find one that
is offering a more comprehensive and diverse range of products than the Swedish manufacturer, which will show industrial diesel engines, trucks, generator sets and products from its mining range.
On the industrial engine side, Scania will show its charge-air cooled, Stage 4/Tier 4 final 9, 13 and 16 L diesels, all of which incorporate Scania’s XPI high-pressure fuel injection system.
The 9.3 L engine is available in rat-ings of 202 to 294 kW at 2100 r/min with maximum torques of 1552 to 1876 Nm. It has a dry weight of 970 kg and is aimed at applications including reach stackers, dumpers, excavators and wheel loaders, the company said.
Targeted toward dumpers, strad-dle carriers, construction equipment, screen ers, cranes and wheel loaders, the 12.7 L Scania diesel has a power output of 257 to 405 kW at 2100 r/min and maximum torque of 1950 to 2373 Nm. Dry weight is 1075 kg.
The 16.4 L is a V8 engine produc-ing 404 to 566 kW at 2100 r/min and
most powerful, 16.4 L V8 engine that delivers 3500 Nm of torque, Scania’s extra heavy-duty overdrive gearbox, Scania Opticruise automated gear changing, 9 or 10 tonne front and tag axles, 32 tonne hub-reduction tandem bogie, drum or disc brakes, air sus-pension or parabolic leaf springs and heavy-duty flitched frame.
The 8x4 version can take on gross train weights of up to 180 or 250 tonnes, depending on the choice of axles and local regulations, the com-pany said. An option for some appli-cations is Scania’s 13 L inline six-cylinder engine that offers torques up to 2500 Nm. Engines are also available that comply with the Euro 6/5/4/3 and EEV emissions levels, as well as Japanese regulations.
Scania generator sets, launched in February at the Middle East Electric-ity Exhibition in Dubai, consist of open or canopy versions with a power range spanning from 250 to 600 kVA at 50 Hz or 280 to 665 at 60 Hz. Units can also be run in parallel for higher outputs. dpi
maximum torque of 2328 to 3183 Nm and dry weight of 1340 kg. It is aimed at defense applications, wood chip-pers, dump trucks and cranes.
Both the 9.3 and 12.7 are inline engines and all three use cooled ex-haust gas recirculation (EGR) and selective catalytic reduction (SCR) without a particulate filter. Scania will also display its advanced Euro 6 truck engines in Munich.
Scania said its development strategy is to secure “full control of all strategic steps in development and performance control.” All development is in-house, including engine management, fuel in-jection and emission control.
The Scania trucks that will be in Mu-nich include the R 730 heavy-haulage tractor powered by a 16.4 L Scania V8 engine; the G 480 one-way tipper with a 13 L inline engine; the G 440 semi-trailer tipper with a 13 L diesel; the G 480 rear-steer 24 tonne hook-lift with a 13 L engine; the P 400 lightweight mixer with a 13 L diesel; and the P 400 on- and off-road tipper.
The G 480, G 440 and G 480 are al-ready Euro 6 compliant, Scania said.

Scania Commercial Vehicles In-dia (SCVI) has released a line of luxury intercity buses designed for medium- to long-distance
travel. The new Metrolink line is based on a system of chassis modules and modular bodywork and will be offered in two- and three-axle form in the Indi-an market, said Anders Grundstromer, managing director of SCVI and senior vice president of the Scania Group.
Grundstromer said the Scania Metro-link is a premium product that is com-pletely in line with Scania’s mission to
be a trusted partner for the transpor-tation industry in India.
Offered in three models, the Scania Metrolink will start going to customers in mid-2013 and assembly of complete coaches will start at Scania’s new facil-ity in Bengaluru in early 2014. Grund-stromer said the company would invest Rs2.5 billion (US$46.2 million) in the plant and “can invest more later.”
The company said it would offer a range of tailored service packages, financing and driver training with the Metrolink. Maintenance and repair contracts are fully backed by Scania’s service network, the company said.
Scania Metrolink HD 45-seater is the smallest of the three models. The
4x2 vehicle is powered by a 9.0 L Sca-nia 231 kW EU Stage 3 diesel engine and incorporates a Scania Opticruise eight-speed automated transmission. The vehicle is 12 m long, 2.6 m wide, 3.7 m high and is equipped with a 465 L fuel tank.
The Scania Metrolink HD 49-seater is a 6x2 model with 49 semisleeper seats (or 53 without calf support), powered by a 13 L Scania EU Stage 3 diesel engine rated 269 kW that drives a Scania Opticruise eight-speed auto-mated transmission. The third axle is hydraulically steered. The vehicle is 13.7 m long, 2.6 m wide, 3.7 m high and also has a 465 L fuel tank.

Ashok Leyland’s new five-axle, long-haul truck has a payload capacity of up to 25 tonnes and is powered by the company’s HA6ETI3U diesel engine rated 134 kW.
The Scania Metrolink HD 53-seater is a 6x2 model featuring 53 semis-leeper seats (or 57 without calf sup-port). It has a similar powertrain to the 49-seat vehicle — a 13 L Scania EU Stage 3 diesel engine rated 306 kW teamed with the Scania Opticruise eight-speed automated transmission, with a third hydraulically steered axle. The Metrolink HD 53-seat bus is 14.5 m long, 2.6 m wide, 3.7 m high and also has a 465 L fuel tank.
The Scania Metrolink was intro-duced exclusively for the Indian mar-ket at this point. In a few years’ time, the Scania Metrolink will grow into a global range, the company said.
New Five-Axle Truck From Ashok Leyland
Ashok Leyland has introduced a new five-axle, long-haul truck with payload capacity of up to 25 tonnes.
The 3718il truck is powered by the company’s HA6ETI3U diesel engine rated 134 kW that is teamed with a nine-speed synchromesh transmission.
The truck has two steerable front axles, two rear axles and a self-steer-able pusher lift axle at the middle that is designed to give the vehicle better balance and greater efficiency in car-rying more loads, the company said. The lift axle automatically retracts up-ward when the vehicle is running in an unloaded condition, which translates
into additional fuel saving and en-hanced tire life, the company said.
“The 3718il has been carefully designed and engineered to meet a specific customer requirement for higher capacity rigid trucks that can carry more loads translating into bet-ter operational economics,” said Vinod K Dasari, managing director of Ashok Leyland. “Our 3718il has been strate-gically positioned as a segment split-ter. It will be attractive for the hitherto 31 tonne truck customers owing to its fuel efficiency and extra load carrying capacity while the tractor trailer cus-tomers will find it attractive because of better maneuverability, lower operat-ing and maintenance costs.”

German filter specialist Mann+ Hummel has released a new line of plastic coolant expan-sion tanks for mobile off-
highway and stationary applications with low- to medium-size production batches.
Benjamin Funk, product manager Industrial Filters at Mann+Hummel, Speyer, Germany, explained that for more than 20 years, the company has produced customized plastic reser-voirs in mass series production for the automotive industry, along with com-mercial vehicles and construction and agricultural machines. When serial production figures are high enough, it is commercially viable to develop a special tank design to fit the vehicle’s installation space.

is not an option because of the long development time and high invest-ment for engineering and tooling. “We have realized that a lot of OEMs tend to adapt already existing tank models for their vehicles or in some cases, rely on rather crude homemade solu-tions,” Funk said.
Mann+Hummel realized that it could combine the company’s ex-perience and competence in plastic coolant reservoirs with a smart, flex-ible solution that could be adapted to fit almost any requirement concern-

“The combination of the four basic shells and three additional acces-sory parts — inlet port, outlet port and filler cap — allows us to offer 24 standard configurations directly avail-able from stock pieces, plus an in-credible amount of other variants with just little modifications,” Funk said. “Our engineers have calculated up to 20,000 possible different variants and stopped counting.”
The MCR series retains the design characteristics utilized across the rest of Mann+Hummel’s customized coolant tanks. For example, the filler cap has a double O-ring seal and an integrated vacuum valve. The cap works as a safety valve with 1.0 bar overpressure threshold. Above that pressure, the cap pops open auto-matically to release the built-up pres-sure inside.
Funk explained that the filling port

includes an integrated overflow func-tionality, with the possible addition of a hose to catch the overflow. The out-let and inlet ports are reinforced for a secure connection and commercially available hose clips can be used, the company said.
“The internal design of the tank features an advanced flow control to prevent the formation of air bubbles in the coolant liquid,” Funk said. “The special design is even able to per-form a degassing function to remove air bubbles from the complete cool-ing system.”
The shell of the reservoir is trans-parent and special stickers can be provided with the tank to mark the minimum and maximum fill levels. The levels can be determined ac-cording to the application and its specific operating conditions. An additional scale of markings is im-
pressed on the outside of the shell for visual inspections.
For mounting the reservoirs to the vehicle, the shells have four pre-defined fixing points for M8 nuts on each side. The tank can be fitted to flat, horizontal or vertical surfaces.
“Upon customer request Mann-+Hummel can also supply an elec-tronic level sensor,” Funk said. “This option is available for the horizontal-mounted version of the coolant tank.”
The new MCR coolant expansion tank range is fully developed and manufactured by Mann+Hummel in the U.K. It will be available for or-ders starting in April and bauma will be used as a platform for the line’s world premiere. dpi

Keeping compact Loaders
on track Bonfiglioli’s new 700CT gearbox result of
partnership with Sauer-Danfoss
Bonfiglioli has launched a new gearbox targeted toward compact track loaders to 5 tonnes with engines to 80 kW. The new 700CT Series travel drive gearbox can be specified with a new inte-
grated hydraulic motor and is fully interchangeable with the existing Bonfiglioli 700CK Series in closed-circuit ap-plications as it has the same chassis-side and sprocket-side dimensions.
At the same time, the new 700CT gearboxes offer en-hancements in efficiency and reliability, the company said.
The 700CT development is the result of an agreement with Sauer-Danfoss for the supply of the hydraulic motor’s cylinder block. Bonfiglioli said that this feature, together with other design improvements, assure more speed, traction and a better maneuvering response.
Among the other new features of the 700CT Series is the positioning of the speed sensor, now located in a safer and more protected position. The new hydraulic motors also have a new internal full-flushing system, for improved hy-draulic motor cooling, resulting in a longer service life and a reduction in the machine’s performance fluctuations.
A new parking brake has also been adopted for more travel drive efficiency and reduced power dissipation at all travel speeds, Bonfiglioli said.
The 700CT Series is available in four sizes with a broad range of control ports and hydraulic motor oil inlets and outlets available. Bonfiglioli said the different configurations are obtained from the same casting, which helps maintain a simple installation for the user and maximizing production flexibility for the manufacturer. dpi

Yanmar’s New Tier 4 Diesels
TNV three- and four-cylinder engines meet EPA and CARB regulations
By Ian Cameron
Yanmar will unveil its new water-cooled, Tier 4- compliant diesel engines at bauma 2013. The company said it is the first manufacturer to have been certified by the California Air Resources
Board (CARB) for diesel engines in the 19 to 56 kW range, along with achieving U.S. Environmental Protection Agency (EPA) Tier 4 compliance.
One of the significant keys to Yanmar’s emissions strategy is the use of an actively regenerated diesel particulate filter (DPF), which the company said helps to achieve low lube oil dilution by fuel oil, which helps provide longer DPF ser-vice life and durability, the company said. In addition, main-tenance intervals have been extended and fuel consumption is reduced when compared to other engines, Yanmar said.
The full CARB range, based mainly on the TNV series, comprises three- and four-cylinder diesels with mostly indi-rect injection (IDI) up to 19 kW and direct injection (DI) from 19 kW to 56 kW.
TNV engines on display in Munich include the 4TNV88C, 4TNV86CT and 4TNV98C. Rated outputs for those engines

are 17.8 kW at 3000 r/min (3TNV80F), 35.5 kW at 3000 r/min (4TNV86CT), 44 kW at 3000 r/min and 51.7 kW at 2500 r/min (4TNV98C).
New engines with an output below 19 kW are the 3TN-M74F (IDI), 3TNV74F (IDI), 3TNV80F (IDI) and 3TNV88F (DI). Yanmar said the first three of those engines offer 100% interchangeability with existing engines and all comply with the latest Tier 4 final emissions under application of the NTE regulations. This allows customers to use Yanmar en-gines at high altitudes worldwide, including in the U.S.A., the company said.
The existing range, with an output between 19 kW and 56 kW, has been modified to meet the current emissions standards. This includes the 3TNV88C/3TNV86CT (DI), 4TNV88C/4TNV86CT (DI) and 4TNV98C/4TNV98CT (DI) engines. dpi

Ready FoR Their Close-Up
JCB’s Ecomax-powered construction machines debuting in Munich
By Ian Cameron
JCB’s solution to EU Stage 3b and EPA Tier 4 emissions reg-ulations will be shown for the first time at bauma 2013 as
machines powered by the company’s Ecomax engine make their debut.
The diesels meet Stage 3b/Tier 4 interim emissions levels without the use of diesel particulate filters (DPF) or other aftertreatment. Instead, JCB has met the regulations through the use of in-cylinder technologies, elimi-nating the need for any external ex-haust aftertreatment — no DPF or additives such as AdBlue — that re-duces operating costs, JCB said.
The JCB Ecomax engine output range has been extended both up and down and will be fitted into machines spanning the 55 to 129 kW range, in-cluding JCB backhoe loaders, Loadall telescopic handlers, wheeled loading
ficiency improvement of up to 6% on top of that achieved by the Ecomax engine. The new variable-flow pump also results in lower lever efforts, re-duced noise levels and rapid control response for up to 30% faster cycle times, the company said.
The backhoe loader range also re-ceives an uprated Powerslide system using a larger hydraulic ram, provid-ing increased side shifting capability at lower engine speeds.
On JCB’s Loadall telescopic han-dler platform, the JCB Ecomax engine will be available in three power ratings dependent on machine model and target customer — 55, 81 or 93 kW. The 55 kW engine produces 6% more torque and 5% more power at low rev-olutions than the previous Stage 3a/Tier 3 engine, resulting in comparative performance but with significantly re-
shovels, the TM range of telescopic boom wheeled loaders, JS excava-tors, rough-terrain forklifts and skid-steer loaders.
On JCB’s 3CX and 4CX backhoe loaders, the Ecomax will be available with a 55, 68 or 81 kW rating and will offer increased torque over its Stage 3a/Tier 3 predecessors with fuel sav-ings of 5%, 4% and 2% respectively, the company said.
The launch of the JCB Ecomax en-gine coincides with the introduction of other machine improvements for backhoe loader users, JCB said. Ma-chines fitted with the Ecomax engine will now also have, as standard, 165 L/min variable flow hydraulic pumps.
JCB said the pumps are configured to match hydraulic flow and pres-sure to the demands placed on the system, leading to a further fuel ef-

JCB will display a range of new machines at bauma, much of which is powered by its own Ecomax diesel engine. The new 427 wheeled loader is one of the exceptions, as a Cummins diesel is teamed with a ZF powershift transmission.
DPI580.indd 1 3/11/13 11:00 AM
duced fuel consumption, according to the company.
Aimed at owner-operators and con-tractors, customers taking the 81 or 93 kW engines will see an average of 15% increase in torque and 10% boost in available low speed power. A variable-speed cooling fan is standard on these two engines and will reduce fuel consumption as well as engine warmup time, JCB said.
The 68 kW Ecomax engine will ini-tially be installed on three of JCB’s midrange JS excavators, the JS115, JS130 and JS145. The new engine installation has been coupled with the optimization of the machine’s hy-draulic circuit and pump configuration which, when combined, has resulted in fuel savings of up to 10% and a 3 dB(A) reduction of in-cab noise.
The introduction of the 93 kW Eco-max engine on JCB’s largest telescopic boom wheeled loader has also provid-ed the opportunity to further improve its productivity with a 100 kg increased lift capacity. This has been achieved by repositioning the machine’s JCB front axle, mitigating the need to add any additional counterweight.
The new engine installation has been introduced inline with the stan-dard fitment of a hydraulic variable-speed cooling fan along with the intro-duction of a refined transmission with TorqueLock in fifth and sixth gears. This contributes to a combined fuel saving of up to 4% while reducing cycle times and improving operator comfort, the company said.
The operation of the updated trans-mission has been simplified, with all shift functions now integrated onto the
single right hand control lever. The transmission dump has been moved to the foot brake for multifunctioning when loading or rehandling.
JCB said the no-aftertreatment ap-proach allows the introduction of a re-calibration option, enabling JCB deal-ers to recalibrate the Ecomax engine to lower injection pressures and turn off the EGR function without any hardware changes. JCB said this recalibration takes the engine out of the emissions tier system, and opens it up for export to less-regulated countries that only of-fer lower quality, higher sulfur content fuels maximizing the residual value without losing Ecomax advantages.
Also at bauma, JCB will launch two new wheeled loaders — the 427 and 437 replacing the 426 and 436 and pow-ered by Cummins QSB 6.7 L engines. The 437 delivers 129 kW — equivalent to the outgoing 436 model. The 427 of-fers 118 kW as well as a 9.4% increase in torque, taking it to 801Nm.
A ZF four-speed automatic power-shift transmission comes as standard with a new optional five-speed power-shift box also available.
Also debuting is a new 4CX Waste-master backhoe loader into the JCB range for the waste and recycling in-dustry driven by an 81 kW Ecomax diesel. Also unveiled in Munich will be the 20-tonne JS20MH — JCB’s first dedicated material handler for the waste and recycling industry and powered by a 97 kW Dieselmax engine. dpi

Stage 4 Takes CenTer sTage
New compact four-cylinder diesel highlights Perkins’ full-line bauma 2013 appearance
By Ian Cameron
Perkins is showing its lineup of EU Stage 4/EPA Tier 4 fi-nal engines up to 225 kW at bauma 2013, spearheaded by
the new compact four cylinder 854F-E34TA diesel.
The 854F-E34TA diesel incorpo-rates specially optimized selective catalytic reduction (SCR) technology for the first time. The system is pack-aged separately from the diesel oxi-dation catalyst (DOC) module, which the company said gives OEMs greater installation flexibility in the engine bay. Space saving is improved through the absence of a diesel particulate filter (DPF), Perkins said.
Performance of the 854F-E34TA has been increased to 90 kW, while the 8% improvement in specific fuel consumption gained at Stage 3b/Tier 4 interim has been retained. Heat re-jection remains similar to its prede-cessor, meaning no major changes to the size of the cooling package,
electronics and diesel exhaust fluid (DEF) line hookups.
Also on show is the single turbo aftercooled 1204F-E44TA, produc-ing 110 kW with aftertreatment com-prising DOC/SCR modules that re-move the need for any regeneration strategy for soot, since the formula-tion of particulate emissions is pre-vented in the combustion process, Perkins said.
The small size of the DOC/SCR module means it can be mounted in a variety of remote locations, freeing up space in the engine bay, especially in more compact equipment. Perkins said it also offers the option of a ser-vice-free DPF aftertreatment unit to meet specific OEM requirements.
The range is completed by the 404F-22, which meets Stage 3b/Tier 4 final regulations. The four-cylinder, 2.2 L model is naturally aspirated and produces 36.4 kW at 3000 r/min and 143 Nm of torque at 1800 r/min.

Alongside the 854F-E34TA, Perkins will also display its 400 and 1200 Series diesels. The single turbo 1206F-E70TA offers up to 151 kW at 2200 r/min, with maximum torque of 870 Nm at 1400 r/min.
In developing the 1200 Series, Perkins said it sought to minimize the impact of the aftertreatment re-quired to meet Stage 4/Tier 4 final requirements, in particular the signif-icant reduction in NOx. Perkins said it has achieved this through packag-ing the DOC, the DPF canister and the SCR system into one integrated module that can be positioned in a machine chassis or directly on top of the engine.
The module is engineered to mini-mize the space taken in the engine bay and incorporates features to ease installation including flexible inlet and outlet options, preinstalled

Three new compact excavators, new asphalt paver among products to be unveiled in Munich
By Ian Cameron
Volvo Construction Equipment (VCE) will introduce a range of new products at bauma 2013, including three compact exca-
vators and an asphalt paver.Driven by Volvo diesel engines,
the ECR25D, ECR58D and ECR88D short swing radius excavators are suited to operating in more space restricted areas. They have a narrow body design and centrally positioned boom on the ECR58D and ECR88D, and the superstructure swings within its track shoe, the company said. The ECR25D excavator only exceeds its track width when equipped with an additional counterweight.
P6870C ABG paver equipped with a Stage 3b Volvo D6 engine delivering 129 kW. The paver is also available with a Volvo D6 Tier 3 engine for non-regulated markets.
It is equipped with three drive modes: paving, shunting and transport. In pav-ing mode, smart power mode is the default setting, which lowers noise and cuts fuel consumption by up to 30%, the company said.
Full engine speed can be selected if paving conditions require full power. Volvo wheeled pavers offer an extra mode called shunting mode for ma-neuvering, loading and unloading. In this mode, paving functions are deac-tivated and active steering is engaged for turning with a tight inner radius of 2.5 m. In transport mode, full travel speed is initiated for quick relocation, and automatic idle occurs when the paver is not in motion. Both shunting and transport modes regulate engine speed proportionally to promote fuel economy, the company said.
Also at bauma, the company will unveil three new models of ultra-high-reach excavators — the 21 m reach EC380DHR, the 27 m reach EC480DHR, and the 32 m reach EC-700CHR — all tailored toward demoli-tion at heights. All Volvo HR machines can be fitted with both high-reach equipment and a standard boom-and-arm configuration.
The EC380DHR and EC480DHR excavators are equipped with Volvo D13 Tier 4 interim/Stage 3b certified engines with gross outputs of 215 and 265 kW respectively. The EC-700CHR excavator is powered by a Volvo D16E EAE3 engine producing 346 kW gross output. dpi
Power for the ECR25D excavator is from the Volvo D1.1A diesel rated 15.5 kW, while the ECR58D is equipped with a four-cylinder D2.6A diesel en-gine rated 36.5 kW and meets Tier 4 final/Stage 3a emissions regulations, the company said. The ECR88D exca-vator has a four-cylinder D2.6H Tier 4 final/Stage 3b engine rated 43 kW.
An auto-idling system is designed to reduce engine speed when the controls are inactive for a specified time (operator preset on the ECR58D and ECR88D via the display between 3 and 20 seconds), reducing running costs and fuel consumption, said VCE.
Also new at bauma is the Volvo

CANecting To The World
Latest telematics and data logging technology for mobile equipment allows vehicle control and GSM or Wi-Fi fleet monitoring
With the exponential growth of electronic controls be-ing integrated into mobile equipment for off-highway
applications, vehicle and equipment manufacturers have been looking for ways to take advantage of the great amount of electronic data now avail-able. Toward that end, North American vehicle control specialist HED has in-troduced CANect, a powerful and con-figurable telematics and data logging system that is distributed in Europe, Asia and Middle East by Switzerland-based Huegli Tech.
CANect is a system comprised of hardware and software designed to convert vehicle data into information that can be accessed by users any-where in the world via a computer or mobile phone. CANect uses a Fre-escale 32-bit microprocessor based on the PowerPC platform — the CL-T00-100 CANect module — which is
ager FTP site for post processing or can be displayed on the CANect telematics web portal. This website can control and monitor up to 4000 vehicle parameters, such as engine and transmission data, vehicle loca-tion and heading, hydraulics system status and many others.
However, the true power of the CA-Nect telematics solution is in the con-figurability of the module and the web portal, Huegli Tech said. The OEM can specify which system variables they want to track on the website and how often these variables are updated. Each machine can be custom config-ured without rewriting code or contact-ing HED to customize the website. In addition, a user can select the vehicle diagnostic mode (data acquisition) on the web portal; the vehicle will track and record data for up to 20 variables every 10 ms for specified length of time. This data can be charted directly via the web portal or downloaded as an Excel file for further analysis. This information can then be used to diagnose hard-to-find issues on the machine.
According to Huegli Tech, another challenge for OEMs dealing with elec-tronics is servicing and updating appli-cation code on vehicles that are in the field. The process can be expensive
the node for the whole system and can serve both as the vehicle main controller as well as provide commu-nication and data logging capabilities.
Huegli Tech said that this approach eliminates the cost of having two con-trollers in the system. Furthermore, the robust IP-67-rated module can be equipped with either GSM cellu-lar or Wi-Fi communications that can both be connected to the secure HED telematics web portal.
The CANect module can also be fit-ted with an SD chip for logging up to 8.0 GB of data locally on the device. This data can be accessed via Wi-Fi, GSM or can be automatically downloaded on to a USB memory stick via the USB host connection on the module. In ad-dition, the CANect module is equipped with a real-time clock, three-axis accel-erometer and up to three CAN ports.
All the collected information can be pushed to an OEM/fleet man-
Diesel Progress international 82 aPril 2013
HED has developed a new data logging and telematics system designed for vehicles and equipment with electronic engines. The
CANect system can provide machine manufacturers and operators with real-time information on vehicle location and status of engines and
components. The system is being distributed in Europe, Asia and Middle East by Switzerland-based Huegli Tech.

and time-consuming, usually involving the training of entire dealer network. With CANect, communication with the vehicle control system can be done also wirelessly via the web portal, so the OEM or fleet manager can access the vehicle from their office and assist the dealer in troubleshooting their vehicles.
To further reduce the cost of serv-ice, HED’s CANect system provides bidirectional communications capabil-ities. Via the web portal CANect will al-low OEMs the ability to download ap-plication code, firmware or EEPROM settings to the vehicle control module, regardless of its location.
CANect is also a valid tool for predic-tive maintenance information. The sys-tem can monitor parameters such as hydraulics pressure so when system pressure no longer reaches a required set point, the vehicle owner is notified to investigate. The CANect system can also reduce downtime and service costs by providing service technicians with extensive diagnostic information prior to arriving at the vehicle in the field. The technician can then be equipped with the right tools and service parts to make an efficient service call and get the vehicle up and running quickly.
To help drive operators and vehi-

The CANect telematics sys-tem by HED allows machine-operating data to be ac-cessed in a variety of ways, including directly to the OEM and user or through the HED web portal that can be viewed on a mobile phone.
cles to perform at optimal levels, the CANect system can monitor a num-ber of variables, such as RPM, brake, acceleration, idle time and provide a comprehensive operator rating. For example, if an operator maintains un-necessarily high engine speeds when stationary, the fleet supervisor can be notified. By changing the operator be-havior, the vehicle efficiency and pro-ductivity could be improved.
With CANect as a fleet-manage-ment tool, fleet managers can quickly draw a geofence for a specific vehicle and set alerts and alarm conditions that will be automatically distributed to assigned individuals via text or e-mail. In addition, this precise infor-mation can be formatted in periodic reports that are sent out via e-mail to specified employees. dpi

Turbocharging AheAd
BorgWarner turbo technologies highlighted on JCB, Mercedes-Benz diesels
A lot of BorgWarner’s turbo-charger technology, including its regulated two-stage (R2S) and variable turbine geometry
(VTG) turbochargers, will be visible at the company’s stand at bauma 2013. But some of it will also be seen in oth-er places, including some new diesel engines from global manufacturers.
In particular, BorgWarner’s turbo-chargers are being used on the new Ecomax engines by JCB Power Sys-tems. The engines comply with EPA Tier 4 interim and EU Stage 3b regu-lations without the need for exhaust af-tertreatment or diesel particulate filters. The Ecomax four-cylinder inline diesels with power ratings from 55 to 129 kW use BorgWarner fixed geometry turbo-chargers with integral wastegate boost control for the lower 55 kW engine, while for the higher ratings, the engines incorporate BorgWarner’s BV55 VTG turbocharger technology.
According to BorgWarner, its BV55 VTG utilizes a high-durability brush-less actuator specifically designed and manufactured for use in heavy-duty turbochargers and EGR valves.
revolution band starting from extremely low engine speeds, while at the same time offering low fuel consumption and emission values, said BorgWarner.
Recent advancements in the B-series turbochargers include titanium compressor wheels along with elec-tric actuators for the wastegate and turbine bypass control. BorgWarner also integrated parts of the exhaust manifold into the turbine housing of these applications for improved ther-modynamics, compact packaging and simplified installation during the engine build.
For this new engine series by Mer-cedes-Benz, BorgWarner also sup-plies its advanced fans and fan drives.
The BorgWarner product range on display at the company’s booth at bau-ma includes also fans and Visctronic fan drives, exhaust gas recirculation valves, coolers, diesel cold-start technology, high temperature sensors, HY-VO chain drives and friction materials. dpi
BorgWarner has also supplied its latest turbocharging technology for the new generation of medium-duty engines from Mercedes-Benz — the OM 934 and OM 936 diesels — that comply with Euro 6 emissions reg-ulations for commercial vehicles. These engines replace the exist-ing 900 series and are available in different output variants, for a wide range of on-highway applications such as the new Mercedes-Benz Atego truck, which will be also dis-played in Munich.
The new Mercedes-Benz 5.1 L four-cylinder OM 934 engine and the 7.7 L six-cylinder OM 936 engine range from 115 to 260 kW and are both equipped with BorgWarner B-series turbochargers. The standard variant of both engines comes with the latest B-series turbo, while the high-perfor-mance variant features BorgWarner’s R2S turbocharging technology.
In the R2S system, a compact high-pressure turbocharger is combined with a larger low-pressure B2 turbo-charging system, which provides dy-namic power delivery across the entire

Plenty Of Stopping — And StArting — At VolVo
Industrial and mining engines now available with automatic stop/start system
By Ian Cameron
Volvo Penta will display its newest diesel engines at bauma 2013, including indus-trial engines that incorporate
the manufacturer’s new automatic start/stop function for industrial and mining applications.
Volvo Penta said the engines pro-vide “outstanding ventilation rates” and comprise 18 variants, nine certified for Tier 2 and nine for Tier 4 interim.
The Tier 2 engines are the TAD 941/1340/1341/1342/1343/1344 VE series ranging from 224 to 357 kW, along with the TAD1640/1641/1642 VE B series, which ranges between 411 to 522 kW. The Tier 4 interim engines
With the stop/start technology, a machine’s engine can be automati-cally shut down when the engine idles more than a preset time span — usually about five to 10 seconds, Vol-vo Penta said. When the operator ac-tivates any of the machine’s controls, the engine is restarted and quickly ramped up to operating speed.
The automatic start/stop function is an optional accessory and in operation can be deactivated and reactivated when needed, Volvo Penta said. dpi
are the TAD1360/1361/1362/1363/ 1364/1365 VE series, rated from 259 to 411 kW and the TAD1660/1661/1662 VE series rated between 411 and 522 kW. All of the Tier 4 interim engines are equipped with selective catalytic reduction (SCR) systems.
Focusing on its stop/start technol-ogy, Volvo Penta said fuel consump-tion is the biggest cost for operators of industrial equipment in areas such as material handling, construction and mining. As fuel can represent as much as 90% of the lifetime operat-ing costs for any application, a sav-ings of 5% is extremely valuable, the company said.

The bauma China show was the stage from which a wide range of new products from Doo-san Infracore Construction
Equipment’s Doosan Heavy, Bobcat and Doosan Portable Power business unit were to be launched to the Chi-nese market.
The new DA40 articulated dump truck (ADT), which the company said has been optimized for extreme off-road performance, was exhibited for the first time. It is powered by a six- cylinder Scania DC13 Tier 2 diesel en-gine with a gross power output of 368 kW at 2100 r/min and offers a 10% in-crease in engine power compared to the previous MT41 truck, along with a 22% increase in gross torque to 2373 Nm at 1300 r/min.
The Doosan Heavy display also included the first showing of the new-generation DL550 wheel loader, the top-of-the-range model in the com-pany’s new family of wheel loaders for markets worldwide. With a bucket capacity of 5.4 m³, the DL550 is for a range of material-handling needs
from loading and transporting granu-lar material to industrial, mining and quarrying applications.
Doosan said a key feature of the DL550 is the Tier 2 12.7 L Scania DC13 turbocharged, air-to-air inter-cooled diesel engine, which delivers a maximum output of 294 kW at 2100 r/min. The high engine power output is combined with a new ZF transmission.
One of the other main attractions was Doosan Heavy’s new DX700LC tonne crawler, the top model in the company’s excavator range designed for heavy-duty mining and quarrying applications and major infrastructure projects.
It is powered by a six-cylinder com-mon rail Isuzu AH-6WG1X turbo-charged diesel engine providing 345 kW at a maximum governed speed of 1800 r/min. The engine meets EPA Tier 3/EU Stage 3 a requirements, the company said.
Bobcat had its first showing of the new-generation T770 compact tracked loader and A770 all-wheel steer loader. Powered by a 68.6 kW

Kubota V3800-DI-T-E3 diesel engine with a rated speed of 2400 r/min, the T770 and A770 replaced the T300/T320 and A300 models, respectively. Both loaders offer higher rated oper-ating capacities and increased engine and hydraulic power, allowing users to take on new, more demanding appli-cations, the company said.
The rated operating capacity and tip-ping load for the T770 are 1611 kg and 4602 kg, respectively. The T770 loader has an operating weight of 4683 kg. The A770 has an operating weight of 4291 kg, a rated operating capacity of 1550 kg and a tipping load of 3100 kg.
Doosan also showed the G630E generator, which has a prime output of 495 kW. The G630E is the larg-est model in the company’s 10-model diesel generator range with prime out-puts from 20 to 495 kW. The G630E is powered by a Doosan P222LE-S diesel engine. dpi

Expanding Flexibility
KTR unveiling new larger coupling for engines up to 250 kW
By Ian Cameron
German power transmission specialist KTR will use bauma 2013 to present its latest prod-uct developments, highlighted
by the launch of its new Monolastic 75 coupling. The Monolastic coupling se-ries is mainly used in hydrostatic drives and is engineered to compensate for misalignment and provide elastic damp-ing of torsional vibrations.
The series has previously been available for drive systems up to 120 kW. The new Monolastic 75 can be used with diesels up to approximately 250 kW and has a permissible rated torque of 1500 Nm. Like the other couplings in the range, the new Mono-lastic 75 is designed to compensate for high radial and angular displace-ments. As a consequence, the power segments of the drive system are less heavily loaded, which results in a lon-ger service life, KTR said.
The preassembled hub can be pro-vided with the requested spline con-figuration. This allows for a simple
axial plug-in assembly of the hydraulic pump without the need for any further tools and devices, KTR said.
Also at bauma, KTR will outline extensions to its BoWex-Elastic HE Series flexible flange couplings de-signed to reliably transmit torque, compensate for misalignment in the drivetrain and dampen vibrations in the drive system.
BoWex-Elastic HE Series couplings have already been applied in con-struction equipment and other mobile machines, but it is now being supple-mented by three additional sizes tar-geting higher performance ranges. In future the couplings will be able to transmit torques up to 20 000 Nm and can therefore be used on diesel gen-erator sets, biogas plants and other higher powered stationary and mobile drive systems. dpi

Pressure AlwAys At the ReAdy
New-generation hydraulic accumulators critical in transmission control applications
Hydraulic accumulators have been shown to be an ef-ficient way to provide hy-draulic pressure in a range
of different applications. German manufacturer Freudenberg Sealing Technologies has developed a range of hydraulic accumulators designed for use in dual-clutch or automated manual transmissions.
In the field of transmission technol-ogy, the pressure needed for start/stop applications in automatic torque converters and dual-clutch transmis-sions is a key function and according to Freudenberg, developing that pres-sure would simply not be economical without hydraulic accumulators.
The start/stop function means that engines and transmissions have to be ready to start at a very short no-tice. However, when an engine shuts down, the pump that supplies the oil in the transmission is also shut down. Without a hydraulic accumulator, the switch elements could not be supplied
that the gas charge remains loss-free over the course of the entire service life, the company said.
Freudenberg said it has also suc-ceeded in optimizing durability and the tribological properties of the in-dividual sliding partners, so there is no need for conventional sealing and guide systems.
Freudenberg Sealing Technolo-gies said it has used modern de-velopment methods to bring several series of hydraulic accumulators to production maturity and these prod-ucts now completely cover the en-tire existing range of applications in commercial vehicles and passenger cars. Their application may expand beyond transmissions to safety ele-ments and other areas where they may be critical to improving energy efficiency, the company said. dpi
with sufficient oil capacity within the required time frame, which is typically no more than 350 ms.
In the past, metallic materials and classic sealing and guide systems were mostly used in the production of hydraulic accumulators. The objec-tive of one of Freudenberg’s current development projects is to use lighter weight materials.
The hydraulic accumulators, made of lightweight materials, allow for a re-duction in weight. They also open the door to completely new approaches, such as the storage of brake energy or the storage of larger volumes com-bined with reduced system weight, the company said.
Freudenberg explained that one key challenge when using modern lightweight materials is diffusion re-sistance. Because these hydraulic accumulators have a gas charge with nitrogen, it is vital to ensure that the materials used are impermeable to ni-trogen. This is the only way to ensure

New hydraulic accumulators by Freudenberg Sealing Technologies use lightweight materials instead of the metallic materials formerly used. They are used for the start/stop function in modern transmis-sions and for the storage of brake energy in energy recovery systems.

Adding To The Family
ehb electronics presents expanded CAN-based machine display technology
By Ian Cameron
Measuring, monitoring and control systems spe-cialist ehb electronics will present an addition to its family of CANflex and CANcor displays at bauma 2013. The CANflex display, which has a
96.5 mm monochrome display and touch screen, will be replaced by the second generation of the CANflex with a bigger 109 mm color display with touch screen.
The customizable human-machine interface is based on the established concept of the 177 mm CANcor display. The new hardware is compatible to the hardware of the CANcor system. As an option, the new CANflex displays may be equipped with the same main processor board that is used in the CANcor to achieve optimum hardware performance, said ehb, which is based in Hannover, Germany.
Both displays can be configured via ehb Workbench con-figuration software.
For the implementation of specific tasks such as control applications, the ehb Workbench software provides a large library to use its own programs as plug-ins. The displays are therefore suitable for all kinds of applications for manufac-turers of mobile and stationary machines, said ehb.
The CANflex is encased in a waterproof housing and the capacitive touch screen has impact-resistant and scratch-resistant safety glass. Using antireflection and bright back-ground illumination, the CANflex HMI is also suited for out-door applications, the company said. dpi

Maintaining Control Sweden’s Nimco specializes in control valves for mobile equipment applications
By Bo SvenSSon
One of the key performance factors for any type of mo-bile equipment comes down to a simple problem — how
well is the load controlled? In order for any machine to operate safely and efficiently, it needs to have well-en-gineered control valves as part of its hydraulic system.
That’s an area where the Swedish company Nimco has focused a good deal of attention on in recent years, with the results being a growing con-trol valve business.
Nimco designs and produces a wide range of hydraulic components, par-ticularly valves, pumps and motors. The company also provides programmable electronics designed to provide full-system integration of all of the hydraulic components, along with its EasyProg software that allows the machine build-er to program, revise and maintain all components integrated in the system.
“Nimco has become a leading man-ufacturer and supplier of directional control valves, remote control units and system integration software to the mobile machine industry,” said Torbjörn Nord, Nimco’s president. “We have engineering and production facilities in Europe, North America and Asia,
reducing valves for each cylinder port. This allows the internal pump pres-sure to be exceeded without consum-ing any pump flow, and still limit maxi-mum flow desired for each function.
An interesting new product intro-duced by Nimco is the PFCV (propor-tional flow control valve) series. This pressure-compensated flow control valve can be used either as a single valve or in multiple units. As a multiple unit the valves are assembled into one block to serve multiple functions.
In its most basic version, the PFCV will regulate the pump flow to a motor or a cylinder at a preset speed and re-gardless of the load, divert the remain-ing oil flow back to the tank. By assem-bling a number of PFCVs together into one block or in series, both the regu-lated and bypassed flow will be divert-ed into a second or third valve circuit. This flow can be reused to run sub-sequent functions, the company said. The valve’s capability to compensate the pressure at all times allows the set speeds to be maintained.
A standard option is a check valve, which can be incorporated into the proportional flow control valve’s body. Its location between the regulated pri-ority flow line and the bypass line is
based on production-adapted design, high-performance machining tools and testing of every product supplied.
“We offer valves that can be tailored to each machine’s specific function, and through our special spool design software we can tailor every function to perform at the optimized speed and with a positive influence of all other functions. Our OC (open center) valves are designed to take advantage of the full stroke of the valve and to have the same performance of each function even at largely different load weights. Our PCLS (post-compensated load sensing) valves offer superior load control with its unique design, where each spool has two compensators al-lowing customization of both the pres-sure and flow.”
Inlet functions for fixed and variable displacement pumps with electrical offloading valves and HPCO (power beyond) functions are available as stan-dard as well as special high flow inlets. Here an LS (load-sensing) compensat-ed spool eliminates the pressure drop between the pump and the valve.
Another feature of the Nimco LS valves is that by having two compen-sators for each spool, it is possible to equip the valves with LS pressure-

Nimco has introduced the proportional flow control valve (PFCV) series. This pressure-compensated flow control valve can be used either as a single valve or in multiple units. As a multiple unit the valves are assembled into one block to serve multiple functions.

intended to protect motors from cavitation due to sudden flow reductions or cutoffs.
Another option for the PFCV is an integrated relief valve to set the maximum pressure available to the motor or mo-tors, when PFCV valves are connected in series. The unit will then act as a torque limiter on the regulated circuit func-tions. With its linear pressure curve the specially designed PPRV (proportional pressure reducing valve) relief valve allows for optimal usage of the motors up to set levels. For activation or deactivation of a regulated flow, the PFCVs can be fitted with a solenoid valve used as a safety device or integrated in the control system.
“When less sophisticated and advanced machine sys-tems are designed and built, the use of simpler compo-nents, still offering high performance at lower cost, could be of great interest,” Nord said.
A further look at Nimco’s program shows directional con-trol valve solutions, where a spool control valve is combined with a pressure compensated flow control valve and the flow to a function is always prioritized and maintained indepen-dently of the operated load. These valves can be connected in series for multifunctional operation of, for instance, motors applications and in combination with a simple gear pump.
Most of Nimco’s open-center valves are designed also in load-sensing versions. An “on-demand, load-sensing valve” enables the valve to work in a system, where a variable dis-placement pump is the main source of oil and pressure supply. In principle an on-demand, load-sensing valves will activate the pump, when the spool is shifted from neutral position, but does not offer individual pressure compensators for the spools.
“We also offer the market’s lowest leakage rates for DSCVs (directional spool control valves),” Nord said. “With special de-sign concepts and manufacturing methods we are able to offer our customers leakage rates as low as 1 cm3/min at 46 cSt for certain products. For larger valves an average leakage of less than 2 cm3/min applies.” dpi
Diesel Progress international 95 aPril 2013
By assembling a num-ber of proportional flow con-
trol valves into one block or in series, both the regulated and bypassed flow will
be diverted into a second or third valve circuit. This flow can be re-used to run subsequent functions. The valve’s capability to compen-sate the pressure all the time allows the set speeds to be maintained.

China’s Weichai Power and the U.K.-based engineering consultant Ri-cardo plc, have announced a precon-cept study for a new Weichai engine family for power generation applica-tions from 1.0 to 3 MW. The compa-nies said the new engine line is pro-jected to be internationally competitive and targeted toward both Chinese and export markets.
The contract calls for Ricardo to collaborate with Weichai on a precon-cept study for the new family of en-gines with configurations ranging from inline six-cylinder to V16 variants. The new engine is targeted at achieving internationally competitive levels of performance and fuel economy and durability and cost of ownership.
Carraro Drive Tech announced it has signed an agreement with AGCO for the supply of transmission sys-tems for a new range of Massey Fer-guson tractors made in AGCO’s plant in Changzhou, China. The five-year agreement is worth €25 million and covers the supply of various types of front axles with integrated drop box for the Massey Ferguson BX200 se-ries tractors rated 60 to 90 kW.
According to Carraro, the tractors are designed for the Chinese market, as well as for export to the U.S., Asia and Africa. The tractors also represent a first phase of AGCO’s planned expan-sion plan in China, which includes the start up of new tractor, baler and com-ponents production in the company’s Changzhou, Yanzhou, Shanghai and Daqing plants.
Konecranes has agreed to buy certain assets of the container han-dling lift truck business of Linde Material Handling. The two groups
have also signed a long-term supply agreement and said they will collab-orate to further increase the global competitiveness of their respective container handling truck activities. The value of the assets purchased is not disclosed. The transaction is expected to close during the second quarter of 2013.
Both companies will keep reach stackers, empty container handlers and laden container handlers in their offer-ing, but after a period of time all manu-facturing will take place in Konecranes facilities. Konecranes Lift Trucks has two production facilities building heavy forklift trucks, empty and laden con-tainer handlers and reach stackers; one in Markaryd, Sweden, and one in Shanghai, China.
The assets acquired by Kone-cranes from Linde Material Handling include the respective product rights. In addition, Konecranes will get ac-cess to Linde Material Handling’s dis-tribution network.
The board of directors of Fiat In-dustrial has approved the merger of Fiat Netherlands Holding N.V. (FNH) with and into Fiat Industrial. The board also approved the merger plan of Fiat Industrial with and into a new, as yet unnamed company, also in the Netherlands — the so-called FI merger. Further, the merger of CNH Global N.V. into a new company was also approved, as a sequence of steps of the same transaction.
Danfoss A/S, Nordborg, Denmark and Sauer-Danfoss Inc., Ames, Iowa, U.S.A, have jointly announced a definitive merger agreement for Dan-foss to acquire the 24.4% of Sauer-Danfoss common shares not already
owned by Danfoss and its affiliates for US$58.50 per share in cash.
The Sauer-Danfoss board approved the transaction based on the unani-mous recommendation of a special committee of the board made up solely of independent directors. The transac-tion does not require antitrust approval and is expected to close in the second quarter of 2013, subject to satisfac-tion of the tender offer and customary closing conditions.
Westport Innovations Inc., a sup-plier of natural gas engines and en-gine technology, said it has reached an agreement with the ENN Group, one of China’s largest private com-panies and a specialist in natural gas fueling technology.
The agreement is aimed at expand-ing natural gas and liquefied natural gas (LNG) transportation applications, technologies and fuel for on-road, off-road, rail and marine applications. ENN is active across a range of en-ergy services and has been building an LNG fueling business in China, with more than 238 natural gas stations in 59 cities.
The agreement with Westport cov-ers the U.S., Canada, China/Asia, Europe, Australia and Africa, and ENN said it expects to begin building liquefaction plants and fuel stations in North America.
Caterpillar Inc. said it will cut 1400 jobs at its Gosselies facility in Belgium. The equipment and engine manufacturer blamed high costs and the weak European economy. Gos-selies manufactures hydraulic exca-vators, loaders and engines and is one of Caterpillar’s largest facilities in Europe, employing 3700 people. dpi
