the distance on the same amount of diesel – that’s a big deal no matter how you look at it!

Environmental concerns also play a massive role in the development of hybrid vehicles. Euro 6 emission standards have already been implemented in Europe in 2014, and the emissions of any manufacturer will need to meet these standards in order to succeed in the industry. Thus a system of continuous environmental research and de-velopment is an absolute necessity for any successful manufacturer in the commercial vehicle industry. A hybrid vehicle is gener-ally defined as one that uses two or more sources of power to propel the vehicle. In a large number of cases this means using the typical internal combustion engine to provide the propulsion until, in so doing, an electric motor has been charged, which can now provide the vehicle’s driving force. When this occurs, the internal combustion engine is not in use, and this of course provides major fuel savings, good for both the environment and one’s wallet.

Clearly, there has been a small-to-big trend in the history of hybrid vehicles and this be-cause hybrid technology, or at least success-ful and viable hybrid technology, is relatively new, even in cars. Cars are generally simpler to deal with than trucks, not necessarily in terms of technology, but rather in terms of

power, size, weight, functionality and pur-pose. Many cars are almost ‘testing grounds’ for new technologies, however, commercial vehicles are not as suited to this as passen-ger vehicles. This is because given the sheer mass of trucks and buses, if something goes wrong with a new technology, it tends to be more serious, but more important than this is the fact that downtime for a commercial vehicle operator is not quite the same as it is for the driver of a car. When a truck is not working, somebody is paying for the sig-nificantly more expensive maintenance and repairs, for it standing on rubber and losing the potential earnings of that truck every day. Trucks need to be reliable, but the delay be-tween the first hybrid cars and the first hy-brid trucks is a good sign that they will be.

At this relatively early stage of hybrid trucks, much of the technology, despite variations from manufacturer to manufacturer, is simi-lar. The use of smaller-volume diesel engines in conjunction with electric motors seems to be the major trend. However, this hybrid surge is not only limited to trucks. Certain manufacturers have been placing huge em-phasis on hybrid technology in their buses.

Will Hybrids be as successful in South Africa as they are in Europe? It is clearly a nec-essary development in terms of emissions in Europe, but this does not seem to be the case in South Africa. While many of these hy-brid commercial vehicles will make their way to South Africa, it is difficult to say when that will be. This raises the question though, is there a market for these vehicles in South Af-rica? While there is no denying the fact that there can be massive fuel savings derived from hybrid trucks and buses, there is also a substantial increase in cost. Will potential buyers be motivated to purchase something that is not yet an absolute legal requirement regarding emission standards? This question is particularly relevant today given the cur-rent economic conditions, not only in South Africa, but throughout the world.

The vast amount of money spent on re-search, development, testing, production and any aspect of hybrid vehicles will without a doubt pay off in the long-run, and these fan-tastic innovations are sure to lead to a de-cline environmental damage as well as oper-ator costs, but how successful will they be in our own market, and when will this be? Only time will tell though, with this brief glimpse into our potential future, we look forward to it with anticipation.

Maybe IAA 2014 provide us further, with that glimpse.

Pierre Sanson, Editor.

The major trend in commercial vehicle development today, is a surge towards hybrid trucks and buses. Virtually every manufacturer had hybrid technology of some sort or other available and it was clear that in recent years, hybrids have been the driving force behind many of the major manufactur-ers’ research and development programmes.

At the IAA in Hanover 2012 it was recog-nizable on a broad front that commercial vehicles are opening up to the alternative powertrains, for example hybrid propulsion.” Why is this, the case, one may ask? Why are vehicles historically known for their ‘simplis-tic’ nature, becoming so technical? A large majority of trucks have been developed on the premise of relative simplicity in order to keep purchase, maintenance and operating costs down. This begs the question, why is the industry that has made these strong, simple workhorses for years heading in this highly scientific and technical direction?

The answer itself is simple, necessity. The same reasoning that underlies previous commercial vehicle production remains: maximum payload, minimum cost. It is com-monly known that as far as operators’ costs are concerned, fuel is unfailingly near the top of the list of expenses. Any saving in the fuel department will naturally lead to a better bottom line. Imagine being able to get twice

FFalls from height are significant prob-lem on construction sites, resulting in serious injury and death of workers. For the victims, their families and the com-munity, each injury is one too many. It is not just the young and inexperienced workers that may be injured. Experience is no guar-antee of immunity from injury.

A legislative framework has been intro-duced in recent years to ensure that com-panies involved in working at height have

control measures in place to prevent injury to persons working at an elevated position.

The appropriate control measures of a particular system of work are generally determined by individual job factors. Risks associated with working at height must be controlled through the use of stable and se-curely fenced work platforms and any other equipment type used for that purpose.

Eazi Access Rental, founded in 2003 was

born from a vision to make working at height safer and more efficient in the workplace. It has in fact, the largest and most diverse fleet of boom lifts, scissor lifts, telehandlers and personnel lifts on the continent.

Eazi Sales and Service was further, found-ed by Larry Smith, Managing Director, and has become a market leader in the sales and servicing of work-at-height solutions, including access platforms, telehandlers and accessories. The extensive range, covering some 90 different access ma-chines and over 15 telehandler models of varying capacities and lift heights, pro-vides solutions and services to many in-dustry sectors including the construction, maritime, petrochemical, manufacturing, warehousing, transport, entertainment and mining industries.

The company’s partnerships with the best global equipment manufacturers and sup-pliers, ensures that every item of equip-ment sold has the protection in the design criteria to make it the safest medium in working at height.

Eazi Sales and Service has built its reputa-tion on the products manufactured by JLG Industries Inc an Oshkosh Corporation com-pany in the USA, which is a leading global manufacturer of aerial work platforms and telescopic material handlers.

JLG’s experience has its roots in the crane manufacturing industry when its founder, John L Grove, in 1947, commenced man-ufacturing the well known Grove hydraulic crane. Leaving the crane manufacturing business behind him, John L Grove started manufacturing the self-propelled telescopic aerial platform in 1969, mainly for the air-craft maintenance industry and JLG Indus-tries was launched.

The manufacturing techniques adopted by JLG in their manufacturing process, has re-sulted in a product which is relatively free of defects. The complete unit is manufac-tured by the company which excludes the power source but includes all the hydrau-lics, booms, cylinders and structures. This principle, adopted by JLG has ensured that each unit is built with equal consistency, a factor unique in the industry.

JLG’s long and well-documented history of innovation in boom lift design was exempli-fied recently with the launch of the world’s largest self-propelled boom lift, the 1850SJ Ultra-Boom. This unit allows working at a height equivalent to nineteen stories and is

able to reach more applications at unprec-edented heights, moving aerial platforms into applications previously reserved for truck-mounted booms.

Eazi Sales and Service further enhanced their equipment portfolio when the Magni range of telehandlers was introduced in 2013 into the local market. Magni is yet another product which is steeped in man-ufacturing tradition and is built with dedi-cation and quality which contributes to the reliability and safety of the equipment on any site. Magni rates amongst the world’s biggest telehandlers in terms of capacity and provides exceptional power and ma-noeuvrability with capacities ranging from 15 to 30 tons.

“We pride ourselves with the quality of the products we sell and the level of backup service we have achieved in the last ten years. Our dedicated staff of skilled tech-nicians have been in the forefront when it comes to customer service”, says Larry Smith. Further, he added, “We receive ex-ceptional support from JLG themselves and are able to count on 97% parts availability from the factory with a guaranteed delivery within three days. Also our local parts avail-ability of 80%, first pick ratio enables us to give our customers a quick turn-around time on maintenance issues”.

Eazi Sales and Service will be exhibiting at Electra Mining again this year and buoyed by the successful response in 2012 they will no doubt be in a position to expound further on the versatility of their product range which covers all sectors of the major industrial markets. b

“We pride ourselves with the quality of the products we sell and the level of backup service we have achieved in the last ten years.”


In Montreal, a Liebherr LRB 255 piling and drilling rig is currently being used with a double rotary drive DBA 300 for the construction of an entry shaft for tunnel excavation. This application is rel-atively new in North America and is being executed for the first time in the province of Quebec.

On the island of Montreal, near the inter-section of Rue Notre-Dame Est and Rue Alphonse D Roy a tunnel with a length of 4 km (2.5 mls) and an internal diameter of 3.6 m (11.8 ft) is planned. After comple-tion it will be used as a water main reach-ing from Montreal to the Rosemont Res-ervoir on Ile de Montreal. The Rosemont Reservoir was shut down in 1978 and is now being put back into service in order to ensure the supply of sufficient drinking water to the city.

The entry shaft for the excavation of the tunnel has an interior diameter of 11 m (36 ft) and is currently being constructed with the help of an LRB 255 piling and drill-ing rig, owned by Centurion Fondation Inc. The entry shaft is built using a compression secant pile wall made up of 74 intersect-ing piles, each with a diameter of 750 mm (29.5”) and a length of 22 m (72.1 ft).

The primary piles, used as filler, are in-stalled first. Upon drilling of the second-ary piles, the rebar cage is vibrated into the pile using an electric vibrator. The piles are drilled into a previously con-structed template, ensuring their exact position. The soil consists of sandy clays and sandy tills with boulders and the piles are drilled approximately half a metre into the shale bedrock.

This project is the first jobsite in the Ca-nadian province of Quebec where an LRB 255 equipped with a DBA 300 double rotary drive is used. This application, also known as cased CFA drilling”, has been chosen by Centurion Fondation due to the high productivity in installing the piles, thus re-ducing construction time and increasing the efficiency of the project.

The 670 kW / 898 hp Liebherr diesel en-gine of the piling and drilling rig provides the power that is required to operate the DBA 300 while at the same time maintain-ing excellent fuel efficiency. The 20 tonnes

(44,960 lbs) Kelly winch and 45 tonnes (101,164 lbs) crowd force ensure that the soil filled auger and casing are pulled out of the ground, while the concrete is being pumped through the hollow stem to un-derneath the auger. Thanks to this method there is no cave-in and the quality of the piles is guaranteed.

The machine operator can monitor the pro-cess on the Liebherr process data record-ing system PDE® in the cabin. This system with large display shows the operator the constructed pile size on the screen and records all relevant pile parameters, such as concrete pressure, concrete volume, depth, etc. b

The CAT 950 GC: A NEW UTILITY LOADER

Caterpillar’s new Cat 950 GC wheel loader has been launched along-side the existing and well proven Cat 950H model to provide customers with a cost effective alternative within the 5 ton payload segment.

The key difference between the two mod-els is in their working applications: the Cat 950H is intended as a high production unit for heavy duty roles, whilst the Cat 950 GC has been purpose-built for support tasks working mainly with loose materials.

Manufactured at Caterpillar’s Qingzhou facility in China, the assembly of the first Cat 950 GC units commenced from the fourth quarter of 2013 for distribution to worldwide markets.

“Rather than offering the ‘all in one’ solu-tion characteristic of the Cat 950H, Cat-erpillar has fielded the Cat 950 GC as a niche wheel loader intended to pass on lower owning and operating savings. This is especially the case where the heavy duty roles for which the Cat 950H have been developed are not required. Either way, both models deliver best in class fuel effi-ciency and excel in their respective roles, with a comparable operating weight of around 18,6 tonnes,” explains Barloworld

Equipment product and application special-ist, Brandon Stonefield. (Barloworld Equip-ment is the Cat dealer for southern Africa.)

Powered by a Cat C7.1 engine that meets Tier 3 emission standards, the Cat 950 GC is well-suited for a wide range of tasks. These include stockpiling, truck loading, material handling, hopper charging and load-and-carry work in quarries, sand and gravel pits, coal operations, stor-age yards, concrete and asphalt plants, and on construction projects for job site preparation, back-filling, pipe handling, plus general cleanup. The Cat 950 GC is also an ideal application match for the agricultural sector.

In contrast, the Cat 950H is designed to perform tasks that include hard bank load-ing as the primary application; rock face loading; waste handling; forestry; demoli-tion and recycling.

Like the Cat 950H, the Cat 950 GC features Caterpillar’s proven Z-bar loader linkage, providing aggressive digging abilities and high breakout forces. The Cat 962H wheel loader model linkage geometry and design has been utilised as standard on the Cat 950 GC to provide best in class bucket pin height and dump clearance.

Load sensing hydraulics produce flow and pressure for the implement system upon demand and only in amounts necessary to perform the needed work functions. Oper-ators will also notice an excellent power balance between rimpull and implements.

As an option, machine owners can fit the Cat Fusion quick coupler system, enabling the rapid interchange of a diverse range of Cat work tools.

On the go, the Cat 950 GC’s electronically controlled automatic powershift counter-shaft transmission features shift protection and is equipped with a split flow oil system for added efficiency, durability and smooth-er gear changes. This contributes signifi-cantly to fast cycle times and extended component life.

In turn, the Cat 950 GC’s Engine Idle Management System (EIMS) maximises fuel efficiency by reducing engine rpm after a specified amount of idle time, al-though in most instances the loader will be hard at work.

“In the end, choosing between the two models will be determined by the down-stream application during the working life of the machine,” adds Stonefield. b

Efficient tunnelling and mining of un-derground resources is being aided by the introduction of specially developed mining software from Sandvik Mining that optimises drilling and radically enhances blasting effectiveness.

After extensive evaluation on mines global-ly, the software has finally been introduced to mines across the sub Saharan region wherever tunnelling and blasting operations are taking place. Its cutting edge technolo-gy allows users to track tunnel development in real time and allows them the opportunity to assess blasting outcomes before they take place.

Intelligent Sandvik Underground Rock Ex-cavation (iSure) is effectively an advanced tunnelling project management suite with tools that provide guidelines for different stages of the drilling and blasting process. These are designed to enable miners to achieve optimal speed and efficiency, while taking loading, hauling etc requirements into account.

Predicting blast effectsAccording to Saltiel Pule, Sandvik’s business line manager for underground drills, the software is unique and has the ability to advance mine tunnelling on the African continent to a higher level. Not only does it guarantee smooth tunnelling work,

but it can specifically guide users on the different stages of the drilling and blasting pattern process to achieve best possible results.

Furthermore, it provides hole-burden cal-culus and enhances hole location accuracy, which in-turn, reduces the need for scaling and ensures better blasting and pull-out. This also allows better rock load ability and smoother collaring when the next round of drilling and blasting begins.

“In a nutshell, iSure combines tunnel-line, theoretical profile design and drill-plan design, as well as data collection analy-sis. Rather than relying on less accurate traditional approaches, it provides users with tunnelling patterns to be configured at the end of the round (when the success of blasts is critical). iSure also offers a project tree that combines all tunnel plans in one project and can include either one tunnel plan or several different plans,” he says.

Pule continues that a tunnel plan, in turn, combines a curve table, tunnel profiles, drill plans, lasers and data collection files, all of which can be controlled separately. iSure uses information relating to explosive power and explosive charging requirements for the different parts of the tunnel cross-section to be entered into the system. It also requires information relating to weight and power of

explosives, as well as the depth of fracture, to enable users to visualise the outcome during the preparation of the pattern.

Users have access to four modules which includes iSure Tunnel for drill and blast design, drilling pattern design, long hole pattern, tunnel line and project files. iSure Bolting provides designs of up to five bolting fans, hole placement and direction, tools for hole generation and fan management, while iSure Report provides the necessary drilling management and process developments required on site. iSure Analysis is used more holistically for measures of drilling data collection and analysis of rock struc-tures and characteristics

“Currently, we have introduced iSure into our 400-series mining jumbos including the DD421-60C drill rig, which provides oper-ators with data relating to their own tunnel developments. It also allows them to view blasting outcomes and make adjustments as required to ensure the best possible pull out. It has already been released in South Korea, Switzerland and Sweden and results prove that marked improvements in tunnel-ling performance are being achieved. “

The new technology marks a distinct leap from manual procedures to high-tech ad-vanced techniques, where miners effectively need to step outside of their comfort-zones and move away from known practices.

“For this reason we are facilitating change management throughout the industry to facilitate acceptance of technology among managers and miners at the mine face. In fact, we are already working to identify technical individuals to undergo operation-al training on the new software (as well as the DD421 60C). We are also working more closely with drillmasters and blasting engi-neers wherever the technology is being ad-opted and have already sent five technical personnel from local mines to Finland for training to gain experience and master the iSure system.

“Technology like this truly has the ability to transform the industry and we believe it is our duty to ensure local mines adopt and embrace technology in order to remain competitive on the global stage,” Pule concludes. b

Bearings International, incorporating Bauer Geared Motors, and part of the Hudaco Group, recently delivered four large Bauer electric motors to Rustenburg and Klerksdorp branch-es in the North West Province.

The Rustenburg branch order called for two off 355kW, 8 Pole, 525 Volt and 50Hz squirrel cage induction motors and one off 800 kW, 8 Pole, 525Volt, and 50Hz squirrel cage induction motors.

All three motors were manufactured as T.E.F.C (IP55) B3 (foot mounted) Class “F” insulation with “B” temperature rise. Rust-enburg branch manager, Deon van Niekerk, discloses that these motors will be fitted to ball mill applications.

The fourth motor, delivered to Klerksdorp on 3rd February 2014, is an 800kW, 4Pole, 6600Volt, 50Hz, manufactured as a CACA (IP55) B3 (foot mounted), squirrel cage induction motor which will be fitted to a multi-stage pump. “We were very pleased with how quickly we were able to honour the delivery to our Rustenburg branch,” says Bearings International Product Manager for Elec-tric Motors and Bauer Electric Motors, Lewis Hiepner. “The order was placed on 26th September 2013 and we delivered the three electric motors on 29th January 2014. This short four month turn-around time was particularly impressive if you take into account that the motors docked at the Durban Harbour over our December holiday period.

According to Hiepner, Bearings International offers a very exten-sive range of electric motors. “In addition to our standard Bauer range of cast iron (0,55kW-450kW) and aluminium (0,09kW-18,5kW) motors which are stocked by our 50+ branches around the country and cross-border, we have also successfully supplied various large low voltage electric motors up to 800kW.” He adds that medium and high voltage Bauer motors have also been sup-plied to various customers over the past three years. Bearings International’s highly trained, skilled personnel will be present to observe the commissioning of the electric motors in an advisory capacity.

Standard products for the electric motor such as bearings for nor-mal maintenance will be stocked within the Bearings International branch network while non-standard parts will be manufactured and supplied as and when required.

“A combination of quality, which has always been a priority of the wide range of leading-brand imported bearings and power trans-mission products we supply, cost effective pricing and reliable de-livery periods were contributing factors to the customers selecting Bearings International as a preferred supplier of large electric mo-tors,” concludes Hiepner. b

ZEST ENERGY CLOSE TO COMMISSIONING ITS

FIRST REFERENCE SITE for diesel power generation in Zambia

Playing a key role in the growth of the Zest WEG Group’s footprint across Africa, group company Zest Energy is moving towards the commissioning of its first reference site for diesel power genera-tion in Zambia. Zest Energy also has instal-lations in Congo, DRC, Tanzania, Zimbabwe and Ghana. The order was placed by Mo-pani Copper Mines (MCM) in August 2013 and calls for the supply and installation of a 12 MVA diesel power plant.

The scope of this project comprises the supply of six Perkins 4016 TAG2 diesel en-gines and 400 V alternators, complete with spare parts for operations and maintenance, six 2250 kVA dry type 400V/11 kV step-up transformers, 11 kV switchgear for the integration of generators from the power plant, all equipment needed for the gen-erator plant control room including syn-chronisation and protection systems and all cabling within the mine’s generator plant building.

Alastair Gerrard, Zest Energy projects man-ager, says that all equipment being supplied will be installed into a newly constructed plant building. Three complete synchronisa-tion panels are also being supplied for inte-gration of the local energy utility Copperbelt Energy Corporation’s 11 kV incomers. The system will have the additional functional-ity to perform peak lopping and will thereby minimise maximum demand.

Installation commenced in June this year and commissioning started in early July, with handover scheduled for the third quar-ter of 2014.

“We’re utilising our group company EnI Electrical, which has an office in Kitwe, to undertake all the installation work and Zest Energy’s team of commissioning en-gineers will do the final setting up and hot commissioning,” says Gerrard. “Owing to the constrained space available on site, we had to optimise on the electrical design and

that’s why we selected dry type transformers which can go into the new plant building. We’re also using a custom engineered busbar system be-tween the generators and the step-up transformers.

“This contract showcases our ability to effectively integrate our power generation instal-lations with the customer’s infrastructure and to promote flexibility in the operation of the generator plant in con-junction the local power utility. Further to this, we always try to add value by considering and factoring in future expan-sion requirements.

“The Mopani installation was a fit for purpose solution, owing to the load complexity on the specific shaft. We were involved in the design and engineering of the plant from the start of this project to ensure that the solu-tion would be technically sound and cost effective.

“Our competitive edge lies in the backing of both WEG and the Zest WEG Group. WEG has a strong interest in investing into Afri-ca, which provides the ideal platform for us to develop robust and custom engineered solutions based on our understanding of the dynamics of power generation in Africa,” Gerrard concludes.

Local content has been maximised on this installation and local labour will be utilised wherever possible. As part of the contract, Zest Energy will conduct on-site plant oper-ator training to ensure that mine personnel will be equipped to run this power genera-tion facility at optimal performance levels.

The Zest WEG Group is spearheading WEG’s advances into new markets and increasing its presence in Africa. Its customer portfolio is made up of the largest companies in Africa’s energy, mining, oil and gas sectors. b

KONECRANES STEPS UP SERVICE PACKAGE with three unique inspection tools

Three innovative and unique devices have been introduced into the South African market by global crane giant Kone-cranes, as part of the ser-vice package offerings to their customers.

All three products have been developed by Konecranes and are implemented by specially trained technicians.

The ‘RailQ’ Runway Sur-vey is an advanced sur-vey technique that uses a remote controlled robot trolley which runs along the rail the crane routine-ly travels on (called the runway), collecting and feeding information into a specially designed sta-tion survey instrument. Any information on mis-alignments of the runway, missing clips, worn pads or uneven, bent or twist-ed sections of the runway structures is processed by Konecranes’ analysis and visualization software. This allows Kone-cranes to survey the runway in a faster, safer and more accurate way. Time savings can be up to 75%.

Another unique inspection tool is the ‘RopeQ’ which checks the state of the inside and the outside of the wire ropes. These can contain up to 400 individual wires which can become worn over years of use. During a visual inspection damage to the internal wires will not show up, in many cases leading to a wire rope being classified as safe whereas it could be highly dangerous. Through Konecranes RopeQ’s magnetic-inductive method internal rope faults are quickly and accurately detected.

The Truconnect Remote Monitoring allows customers to check on the performance of the cranes on their own computer through online access to a special Konecranes report-back system. This data allows customers to make better decisions and increase the productivity of the cranes.

Konecranes engineers compile focused safety-related data and make recommendations regarding the maintenance, repairs and possible costly problems that can be avoided when detected early enough.

“Service and maintenance are a very high priority for us”, says John MacDonald, Sales & Marketing Manager for Konecranes Southern Af-rica. “These new products place us at a huge advantage in terms of fulfilling our mandate to service and maintain all makes of cranes”. b

South African multinational Condra has harnessed company experience in high-speed, high-lift crane technology to design and manufacture a unique structure for fast-tracking the pre-sink phase of new mineshafts.

A prototype has been built and is currently under test.

Radically different from the level-luffing type of crane traditional-ly used for pre-sinking, the prototype machine comprises a portal crane with a 25-ton main hoist sufficiently fast to render feasible a period of just three months for a typical 50-m mineshaft pre-sink.

The portal frame additionally accommodates two stage-winders running parallel to the main hoist and at the same height, for raising and lowering the drilling stage.

Condra undertook research and development on its prototype during the second half of last year, designing the 25-ton hoist unit so that it is able to deliver a lifting speed of 30m/min, or almost eight times faster that the 4m/min usually required.

Besides hoist speed and frame layout, considerable research was also carried out on the drives and gearboxes, on cabin access, on remote operation, and on safety devices.

With a span of 24,4 metres, a height of 15,1 m, and a below-ground lift height of 80,0 metres, the Condra gantry has a very impressive physical presence.

During an actual pre-sink, it will stand over the shaft mouth to fa-cilitate the removal of excavated earth and rock in a kibble lifted by the portal crane’s 25-ton high-speed hoist through a hole in the centre of the drilling stage, remaining in place until the shaft has been drilled, blasted, supported, cleaned and lined with concrete.

Condra chose a portal design for the prototype crane to allow it to be moved along rails to adjacent shaft sites as necessary. Such changes in location would take just a few days instead of the three to four weeks needed to move and pre-rig a level-luffing crane.

In addition, the crane quickly tows a rail-mounted integral blast cov-er over the shaft mouth during blasting.

Quality control during Condra’s manufacture of the prototype was strict. For example, the hoist was intensively checked using mag-netic particle inspection of the entire drum.

Germiston-based Condra is the only multinational crane manufac-turer headquartered in South Africa, with a factory in Bulgaria and a worldwide distribution network. b

LIFTING

BRIEF ‘GUEST APPEARANCE’: TEREX® AC 100/4L AND TEREX® CHALLENGER 3180 all terrain cranes lift 60-meter steel pipe

Three hours. That was all the time available to the Swiss crane service provider, Toggenburger, to lift a 60-m long steel district heating pipe onto a sup-port frame on behalf of Basel-based Caliqua AG. The busy rail line and the road close to the construction site on the grounds of a paper mill in the Swiss town of Perlen could not be closed to traffic for any longer, which explains why cranes that could be set up in no time were needed for this job. Toggen-burger therefore selected the Terex® Chal-lenger 3180 and the Terex® AC 100/4L all terrain cranes.

“It was all down to speed and precision on this job to avoid blocking the rail traffic, as well as the 40 trucks a day supplying the paper mill, for an unnecessarily long period of time. Our two Terex cranes delivered on both counts,” states Project Manager André Huber. The pair of Terex cranes could be driven to site within an hour.

Then everything went quickly and according to plan on site: the two crane operators set up their cranes and were ready for oper-ation within 30 minutes. “The cranes only needed their basic counterweight for this load, with the result that we did not have to deploy any additional transport vehi-

cles, saving valuable time,” explains André Huber. With main booms set to a length of 35 m and standard outrigger configura-tions, the two Terex cranes were quickly in a position to lift the 60-meter long, 24-tonne steel pipe within a working radius of 15 m to the required height of 15 m.

The challenge with this lift was that both cranes had to work with the utmost preci-sion and in perfect sync with each other as the steel pipe, supported at four points, was not allowed to bend too much during the lift. The crane operators relied on the proven Terex IC-1 crane controls and a radio oper-ator to achieve this. The pipe was therefore placed safely in position in the alloted time, despite the time pressure, thanks to the routine interaction of humans and technol-ogy. “We needed just three hours and three team members to set up and dismantle the cranes and complete the lift itself. This job could not have been done more economi-cally – it went perfectly,” summarized André Huber with satisfaction.

With a 50-meter (164-ft) main boom com-bined with a 16-meter (52.5-ft) extension, the Terex® Challenger 3180 provides the longest system length in the 60-tonne (66.1 US-t) all terrain capacity class. This

includes (optional) all-wheel steering with drive chain 6x6x6 and 495/95R25 tires. Fully equipped, including its maximum 12.1-tonne (13.3 US-t) counterweight, the Challenger 3180 all terrain crane also pro-vides one of the strongest system in the 60-t (66.1 US-t) capacity class, with maximum lifting capacity of 37.9 tonnes (41.7 US t) at 4 meter (13.1-ft) radius. In this config-uration, it is still roadable and designed for one-man-operation in countries with 15-tonne (16.5 US-t) axle-load limitations.

The compact Terex® AC 100/4L all terrain crane is the only crane in the 100-tonne capacity class to feature a standard truck width of 2.55 meters, even when equipped with large 445/95R25 tires. With a telescopic main boom of 59.4 m and the 10-meter section of its 19-meter-long dou-ble folding jib, the crane also features one of the longest system lengths (69.5 m) that can travel on four axles while complying with a 12-tonne axle load limit. The crane reaches its maximum system length of 81.7 m together with an extension system characterized by a high level of versatility: The 19-meter-long double folding jib can be mounted directly on the telescopic boom or on an additional 8-meter extension in-stalled between the telescopic boom and the double folding jib, enabling fast setup times at construction sites. It is possible to offset either the 19-meter double folding jib on the extension or the entire 27 meters (the 19-meter double jib plus the 8-meter exten-sion) on the telescopic boom. This makes it possible to either work with a large working radius or overcome projecting edges of up to 63 meters. A powerful 335-kW (445 hp) engine is responsible for the AC 100/4L all terrain crane’s cost-effective operation, ex-cellent road-traveling performance, and out-standing fuel economy.

The historic Toggenburger Company was founded a century ago by Emil Toggenburger to operate a gravel pit. Today Toggenburger companies, with their headquarters in Win-terthur, employ around 250 people and offer, among other things, comprehensive services in the lifting & transport sectors. Further business areas include environmental tech-nology, renaturation/earthworks, repairs and even gravel and concrete. b


GREINER INDUSTRIES BREAKS company records with GMK6400

I t’s been nearly a year since Greiner In-dustries received its Grove GMK6400 and since then, the crane has worked tirelessly.

The company is completing all types of projects with the 450 ton capacity all-ter-rain crane – highway projects, construction jobs, factory maintenance and much more, repeatedly surpassing its own productivity and efficiency records. What’s more, the Mount Joy, Pa.-based company is bidding and winning jobs it never did before it took

delivery of the GMK6400. Ben Daugherty, crane division manager at Greiner, said the GMK6400 has fundamentally changed his company.

It’s already racked up some 1,500 hours since August of 2013. Initially, Daugherty said, Greiner was looking at seven-axle 500 ton cranes, but then took notice of the 6-axle GMK6400.

“In our market, there are a lot of 500 ton cranes. Initially, I was going to buy a similar

crane, but decided to do something differ-ent that would enable us to be competitive – to stand out from all of the other compa-nies,” Daugherty said.

The decision changed Greiner’s lifting busi-ness, as it began to win jobs it couldn’t previously. With only six axles making for a compact footprint on the GMK6400, Greiner has been able to work on job sites where seven-axle cranes can’t fit. Yet, the com-pany still has the lifting power of a 450 ton crane to complete jobs that typically require


LIFTING

larger cranes. Take a recent Greiner project at a Glatfelter paper company plant. Once a year, the plant shuts down for routine main-tenance. Greiner bid on the job to change out evaporator effects inside the plant, go-ing up against several seven-axle, 500 ton cranes owned by its competitors. And with space on the job site at a minimum, Grein-er had the advantage with the GMK6400’s compact size.

“Initially, Glatfelter was doubtful we could complete the project, but once we showed

them the GMK6400 and its capabilities, we were awarded the job,” Daugherty said. “We were less expensive than the bigger cranes and because our crane would take up less space in the plant, the company was able to keep a service line open and continue working.”

Greiner lifted inside the plant for 11 days straight, changing out the 15 USt evapora-tor effects 24 hours a day – a new company record. The lifts were up to 150 ft tall, and the loads were another 160 ft away from the crane in radius, so Greiner used the GMK6400’s luffing jib to cover the large di-ameter. The company rigged the luffing jib inside the plant, and then moved the crane into place.

“A 300 ton crane couldn’t have made the lift and a 500 ton crane would have been too big for the space,” Daugherty said. “In the end, we only had 3 ft to spare on either side of the GMK6400.”

Soon, Greiner will surpass another compa-ny record with the GMK6400, spending up to an estimated 80 straight days lifting on a project to help construct the Alexandria Renew Nutrient Management Facility, a wastewater treatment plant in Alexandria, Va. This time the company is using the crane’s heavy lift jib to tilt and place pre-cast concrete panels. The crane is rigged with 131 ft of main boom, along with the heavy duty jib, to lift 25 ton panels from a radius of 105 ft.

The wastewater treatment plant is unique, as it’s being constructed over an old land-fill. The precast panels provide the walls for the structure, where water tanks are being placed. A roof will be placed over the tank, then it will be covered with ground and a soccer stadium will be constructed on top.

“I could not have won or completed this job without the GMK6400,” Daugherty said. “It’s the largest contract that we’ve ever won at Greiner.”

The varied amount of work that Greiner is completing with the crane is testament to its versatility. Beyond the reach, capacity and compact nature of the crane, Daugh-erty points to five outrigger positions as a key feature. Greiner has found great use in the three-quarter position.

“The seven-axle cranes are a lot wider from outrigger mat to mat, and most companies’ cranes have only mid- and full-outrigger positions,” he said. “If I’m in a restricted space, I can run the outriggers in a 24 ft stance and still have a very impressive load chart.”

The MEGATRAK suspension with MegaDrive has also been especially useful. Already utilizing a smaller footprint than all other cranes in its lifting class, the independent all-wheel steering makes it even more ma-neuverable. This, for example, is what al-lowed Greiner to set up the luffing jib on the paper plant project and easily move the crane into the tight quarters from which it needed to lift.

Greiner has also made good use of the crane’s self-rigging MegaWingLift attach-ment, which boosts capacity by nearly 70 percent. In fact, Daugherty said the com-pany has used the crane in nearly every configuration possible since taking delivery.

Greiner purchased the GMK6400 from Har-risburg, Pa.-based Stephenson Equipment. The two companies have been doing busi-ness together for some 20 years. Daugherty said the stellar product support from the Manitowoc Crane Care partner was another reason to purchase the crane.

“Stephenson will drop whatever it’s doing to support my needs and that’s a huge sell-ing point – other companies don’t have that kind of product support,” he explained. “The first night we had the GMK6400 we took it to work on a bridge project. We were very unsure about using a new crane on a job so soon after purchasing it. There was a $20,000 charge for each hour if we went over the scheduled stop time. Stephenson sent a technician to stay with us overnight for 12 hours just in case something hap-pened. That kind of support is priceless.”

Greiner has been performing lift work since 1978 and specializes in infrastructure projects throughout the Pennsylvania, Maryland and Washington, D.C region. The company has many cranes in its fleet from Manitowoc, including several Grove truck cranes and National Crane boom trucks. It purchased the GMK6400 as an update to the company’s previous GMK6300B all-terrain crane. b

Six Potain tower cranes have built two 280 m tall bridge pylons high in the clouds above the mountains of south-ern China. The cranes spent two-and-a-half years building the pylons at the Chishi Grand Bridge, which will span 1,470 m and carry its road deck 180 m above the ground. The bridge will open at the end of this year.

The China Railway Major Bridge Engineer-ing Group (CRMBEC) is the main contractor on the project which, at 70 m wide, will be one of the widest cable-stayed bridges in the world. CRMBEC owns and operates the Potain tower cranes used on the project and the company has enjoyed a long and successful relationship with Manitowoc, as Jiang Xiong, CRMBEC project manager, ex-plains.

“We have worked with Potain since 2002 and have an excellent relationship with them – we appreciate both their high qual-ity products and their attentive service,” he says. “The advanced technology, excellent efficiency and reliable operation of Potain cranes give us the peace of mind that you need on this type of large-scale project. We cannot have delays as it would have a major impact on the rest of the project. We spent considerable time analyzing the correct crane choice for this project before selecting Potain, and once again they have proven to be the best choice.”

Standing up to 310 m tall, the six Potain tower cranes endured the full force of Hunan’s subtropical climate during their 30-month posting at the Chishi Grand Bridge. Monsoon rain and extreme humidity

were among the challenges at the job site.

Communication between ground crews and operators was also key as the cranes were often hidden in the clouds, with no view of the ground below.

The Potain cranes built two of the bridge’s four pylons, each of which has 24 exteri-or sides and 36 interior sides, forming a unique S-shape structure. This technical ar-rangement made construction all the more complicated.

The cranes lifted a wide variety of con-struction materials, including formwork and steel structures, in loads that tested their maximum capacities, which ranged

up to 16 t. Work began on the Chishi

Grand Bridge in March 2010. The Potain tower cranes were erected at the job site in March 2011 and have recently finished work. The cranes on site included two MC 200s and two cranes that mix the mast of an MC 480 with the jib of an MC 320 K16. All of the cranes were built Potain’s fac-tory in Zhangjiagang, China. CRMBEC is a wholly-owned subsidiary of China Railway Group Ltd and specializes in bridge con-struction, completing some of the largest in the world to date. The company has more than 16,000 employees. The Chishi Grand Bridge forms part of the Xiarong Express-way, which connects Rucheng to Chenzhou in the southeast of Hunan province. b

APEX 2014The Apex 2014 international show for access equipment re-vealed some innovations in the work at height industry. One of the new innovations and depar-ture and the most noticeable was the introduction of tracked platforms. Tracked platforms is still a niche product but is getting bigger. Although the concept popular in Europe, the trend is fast becoming accept-ed by big buyers in both North America and Australia. Some of the larger units have a work-ing height of 43 m and an out-reach of 19 m whilst the bucket capacity can be up to 300 kg. What will also appeal in some quarters is the choice of either diesel or hybrid power thus in-creasing their versatility.

SKYJACK BOOM ASSISTS IN WINDMILL REPAIRSSkyjacks recently helped repair a 19th century windmill using an SJ66T telescopic boom lift at the Avoncroft Museum in Worcestershire, UK. The SJ66T spent a week working to repair the 200 year old windmill. The windmill is located at the far end of the museum and to reach the windmill’s broken sails, the team had to navigate over a large field and work around a number of historic buildings. The SJ66T was ideal because its four-wheel-drive system al-lowed them to move easily over the rough terrain. Repairing the windmill was a very delicate task, but the machine has the control and manoeuvrability that was needed to complete the project.

SOLVING THE PROBLEM: “FALLS FROM HEIGHT”

Welcome to our first dedicated “work at height” insert with it’s much needed exposure to the mining, construction and building industries clarifying the often mis-construed concept of working at heights!

This follows our initial exposure in the print me-dia some 5 years ago when the old associations “SAEMA” (Specialised Access, Engineering and Manufacturers Association) and “RAFAA” (Rope Access and Fall Arrest Association) shared a bi-monthly specialist magazine. These two independent trade associations served the needs of persons working in elevated positions. These synergies lead to the formation of the In-stitute for Work at Height and its Professional Body. The Institute for Work at Height is now the official organ for the industry and is mandated to inform the world of the services and activities involved in working at height.

The Institute is made up of two constituent parts namely:-

The Trade Association which caters for the needs of corporate members, suppliers and any other organisation associated with the work at height sector. There are seven specialist chambers within its structure, each addressing specific types of equipment or services. The chambers: - Mobile Elevated Work Platforms; Suspended Access Equipment; Rope Access; Aluminium Towers and Ladders; Falsework; Scaffolding; Fall Arrest.

The Professional Body which is mandated by SAQA to look after the interest of practitioners operating in this sector as well as to ensure the interest and safety of the general public in their interactions with these practitioners. It has reg-istered several professional designations with SAQA and has an extensive, and growing, list of recognised, accredited training providers. It

the short time that is has been operational it has registered in excess of eight thousand persons working in this field. The need for persons to be competent and certified is also driven by the Occupational Health and Safety Act and its var-ious regulations

I want to thank Capital Equipment News for their initiative in setting up this publication and look forward to a long and mutually beneficial relationship with them.

The single biggest cause of workplace fa-talities and major injury at work in South Africa is falls from height. In fact, this problem is worldwide and some countries are taking great strides to reduce the risk and miti-gate the outcomes of people and objects falling from height. It’s time for us to step up to the mark and do the same.

Working at Height continues to challenge all in-dustries across the Nation. We are witnessing, throughout South Africa, a constant breach of Regulations with unsafe acts and conditions com-monplace amongst our working areas. These actions are truly appalling, unacceptable and di-minish our efforts to promote a safer South Africa. More needs to be done to address this problem-atic safety culture and the awe related to it, by working ‘together’ to reduce and eliminate ‘falls from height’. Tackling this challenge requires a collaborative approach and decisive action from all stakeholders. Occupational Health and Safety professionals must assist in the implementation of ‘good practice’ whilst advising employers, Clients and other end users on ‘best practice’ for working at height in every industry.

PROVINCIAL NEWS

As part of an all out drive to increase safety awareness and safety standards in the working at heights industry the Con-struction Regulations was revised and issued on the 7th February 2014 with the addition of regulations for Fall Protection, Rope Access Work, Suspended Platforms, and in es-sence ANYWHERE where there is a risk of a fall. This can include above ground activities right through to underground activities that involve confined spaces. The Institute for Work at Height was a big factor in these changes and sat on the work committee for these changes to en-sure industry standards are met and remain consistent. What this means now is that any person working in an elevated position where there is a risk of a fall needs to be trained and assessed as competent against a registered designation as mandat-ed by the Institute for Work at Height Professional Body and must hold a Licence to Operate for the relevant scope of work.

Using an accredited training provider who is a member of the Professional Body is a necessity in ensuring you meet legislative requirements.

Gravitek one of the leading rope access companies in South Africa has a track record that sometimes exceeds all expectations with their core of highly skilled and experienced technicians. Dominating the Durban skyline is the Millenium Tower on the Bluff. With its close proximity to the sea, corrosion issues and the high wind factor are a major challenge for the maintenance crews. The shape of the tower and the positioning of cables and the panels make the task more daunting. Rope access has been the hallmark of the successful maintenance and inspection solutions Gravitek has provided the client.

Goscor Access Rental in Cape Town has grown tremendously since its inception a year ago. Formerly known as African Access by the locals, it has become a key to the success of the Group and has also provided a platform for the company to expand its activities in the area. Buoyed by the new range of Genie access machines available

to the company, the market has responded well to the safety and technical features inherent in the machines. Working closely with Goscor High Reach, the rental company are continuously updated on all safety aspects of working at height which ensure their clients work within those parameters.

Training and skills development SAFE WORKING AT HEIGHT WITH MOBILE ACCESS TOWERS

Work at Height is a specialization to other occupations to allow these oc-cupations to work safely at elevated heights, by means of specialised equipment which includes Rope Access, Steel Scaf-folding, Access Towers and Ladders, Mobile Elevating Work Platforms, Temporary Sus-pended Platforms, False Work as well as Fall Arrest and Fall Prevention which is generic to all work at height trades. Working at height cuts across a large spectrum of industries such as, construction, building, maintenance, electrical, welding, telecoms and other infra structure developments etc. The IWH Pro-fessional Body is in fact a “key” player in the training process. Having tthe Trade Associa-tion as its ‘bed partner’, the IWH PB is indeed ideally suited to undertake this role simply because of the fact that they represent the voice of the Industry. The Trade Association as it consist of member organisations that are able to provide all the industry expertise nec-essary to the Professional Body

Within our Professional Body we have a committee known as the CEP (Communities of Expert Practice). The CEP is made of key stakeholders drawn from interest groups, specialists in the sub-field, organised labour and organised business.

What does the IWH Professional Body mean for industry?• Regulated and controlled training of all

persons exposed to the risks of working at height, strictly in accordance with the requirements of the National Qualifica-tions Framework.

• Any training provider that wishes to offer training that leads to the awarding of a professional designation in the work at height industry should seek recognition from the IWH professional body. A training provider should first be accredited with one of the recognised Quality Assurance Bodies/SETA ETQA’s before they can be recognised by the IWH Prof Body

• All recognised training providers will be listed on the IWH PB website and will be entitled to display the words “IWH PB Recognised Training Provider” on their documentation.

Firstly we must clarify what working at height actually entails. A widely ac-cepted definition for ‘Work at Height’ is any place, if precautions are not taken, where a person has the potential of falling from, off or into another level which may cause personal injury. That can be above or below ground where a person can fall from an edge, through an opening (even in the floor or ground) or through a fragile surface.

Over the series of ‘Safety’ articles we will address safe working at height from various options for temporary platforms and work stations. One such platform is the mobile access tower. This equipment is manufactured to an approved standard, which is SANS 51004 in South Africa. With the appropriate training you are shown how to assemble, dismantle, use, move, and inspect a mobile access tower in a safe and controlled manner.

PASMA, the Prefabricated Access Sup-pliers and Manufacturers Association, have developed training over a number of years

and the two widely accepted methods of assembly are, Through The Trap (3T) and Advance Guard Rail (AGR). Training is de-livered through PASMA Approved Training Centres, through SETA and IWH registered training providers, with the courses aligned with the Unit Standards in South Africa.

There are several types of aluminium access tower available, so it is impera-tive that standards are followed and that tower components are not mixed up. The manufacturer’s user manual must be fol-lowed during all stages of assembly, use, moving and dismantling to maintain safety throughout the entire process. Attention must also be made to the storage, inspec-tion and repair requirements that need to be controlled whilst following the manufac-turer’s instructions.

PASMA is working with the IWH in South Africa to improve safety when working at height. Together we can make a difference and reduce the numbers of falls, causing serious injuries and fatalities across all in-dustries, where access towers are utilised.



MARINE TECHNOLOGY

HIGH EFFICIENCY AND DYNAMIC POSITIONING WITH Voith propulsion systems and vessel concepts

Offshore exploration and energy gen-eration are gaining in importance worldwide. As a consequence, the number of offshore wind turbines as well as oil and gas platforms is increasing. All of these must regularly be supplied with staff, fresh water and drilling material. In recent years, Voith has been equipping an ever larger number of platform supply and in-stallation vessels with propulsion systems. To ensure positioning accuracy to the meter, the Voith Schneider Propellers (VSP) used as main propulsion systems are increasing-ly complemented by Voith Inline Thrusters (VIT) as bow thrusters on larger vessels.

With its new vessel concepts, Voith high-lights the advantages of its propulsion systems regarding dynamic positioning (DP) and combines them with ideally suit-ed designs. The “High Flow 4” offshore construction vessel presented as a model enables dynamic positioning in currents of up to ten knots and is set to transform the offshore market. The catamaran is powered by four VSP, boasts an open deck space of approximately 1,000 square meters and is designed to install tidal energy turbines in

high energy tidal streams. The Maintainer vessel concept also, as a model, is similarly effective. It has been developed by Voith to-gether with NavConsult, a subsidiary of the SCHRAMM group.

The service vessel will close the gap be-tween the catamarans that are currently used and large offshore supply vessels for the installation and maintenance of wind turbines.

The Maintainer concept boasts DP2 and permits safe access to the wind turbines in a weather window up to a significant wave height of 2.5 meters. The combination of two VSP and two VIT 850-200 bow thrust-ers ensures precise dynamic positioning within the wind farm.

With its compact design, the VIT can be integrated in more slender hull shapes and can be placed more towards the front of the bow for increased lever arm. The sys-tem has very low noise emissions. Its noise levels are 23 dB(A) below those of conven-tional bow thrusters, making it possible to install a VIT in the immediate vicinity of the

cabins. The Voith size 10 VSP is a versatile propulsion system for offshore applications, tugs and ferries is demonstrated by vari-ous vessel models on display: the platform supply vessel Edda Fides, the new Walk-to-Work vessel owned by logistics provider Royal Wagenborg and the Voith Water Trac-tor (VWT) Shinano.

Shinano is the first Voith Water Tractor with a fully electronic control system. The im-provements resulting from this VSP control system can be experienced at the booth us-ing the control system on display: The con-trol stand level has been modified; bridge components such as joystick, wheel and propulsion control lever have been ergo-nomically designed.

In addition to the optimized handling char-acteristics, the system offers a reduction in energy consumption achieved by direct trig-gering of the proportional valves and omis-sion of a separate hydraulic unit. Now not only offshore supply vessels but also ferries are successfully being equipped with the electronic control system by Voith. b


The new hydraulic underground hand-held rock drill-system (HRD100) is one of the most powerful underground handheld rock drills on the market. The smart power pack monitors all vital func-tions and can compensate for pressure changes automatically

The crucial benefit of the HRD100 has an outstanding drill rate and considerable energy efficiency compared to conven-tional pneumatic or electrical rock drills. Measured noise is approximately 50 per-cent lower than that of a pneumatic drill. The polyurethane cover shields noise and makes the unit shockproof. The unit can handle a drop from 2 m.

THE HRD system consists of the rock drill (RD100), the power pack (PP100) and a se-lection of water pusher legs. All hoses and cables are included.

The HRD100 features a five-step water ad-justment to help the operator use the right amount of water for each step. And when the drilling stops, the flow stops automat-ically.

“We really made an effort to provide high drill rates at low operational cost. But it is equally important to create a system that save the operators energy by being light and reliable”, says Oleg Korobotchkine the product line manager.

Working underground is hard work, but thanks to one-handed operation and car-rying handles, the HRD-system makes it easier. The stackable PP100 power pack basically manages itself. Smart functions monitor oil flow and oil temperature. Wa-ter-cooling and automatic overheat pro-tection means safety and reliability are at its core.

The system also monitors oil volume and compensates for pressure differences. That allows you to work with the PP100 at a 45° angle, without power loss. Simple tools make it easy to top-up hydraulic oil in the mine. Atlas Copco is a world-leading provider of sustainable productivity solutions.

ECO-FRIENDLY HOPPERS from Samson

BLT SA’s range of Samson bulk ma-terials handling equipment includes travelling hoppers, which provide ef-ficient handling, flexibility and environmen-tal protection, in the discharge of dry bulk materials.

“Samson Eco-hoppers, which are suitable for discharge by grab cranes, are designed to suit the characteristics and flow proper-ties of virtually any bulk material, including coal, iron ore, gypsum, copper concen-trates, soda ash and wood chips,” says Keith Dowie, project development man-ager for BLT SA’s Samson bulk materials handling equipment. “These robust grab unloading hoppers offer handling rates to 5 000 tonnes per hour, depending on grab crane performance.”

Eco-hoppers, which are manufactured to withstand tough conditions at ports, also have an effective dust control system that minimises the escape of dust during the grab discharge cycle. Environmental pol-lution caused by fugitive dust, is a major problem in dry bulk handling.

These hoppers have an upper and low-er section, separated by a dust retention feature, the ‘Flex-Flap’. This divider, which comprises a series of pressed steel sec-tions and vertical rubber flaps, opens to al-low the free flow of material into the hopper and closes to prevent the flow of air out of the hopper.

When bulk material is released by the grab, it falls through the Flex-Flap and accumu-lates in the inner hopper below. The hop-per system automatically closes as a result of the newly created pressure differential between the hopper and the atmosphere, forming a seal to contain the dust contami-nated air. Integral reverse jet filters are po-sitioned around the hopper inlet to extract and clean the dust laden air. Collected dust is then re-cycled into the mainstream of material.

The Flex-Flap feature reduces the volume of exhausted air necessary to control fugitive dust and requires the use of small, com-pact filters rather than a large de-dusting system.

The standard Samson Eco-hopper series includes circular hoppers, which are de-

signed to accommodate grab capacities be-tween 1 and 37 m³. Each hopper size has a corresponding high or low level framework, depending on the chosen discharge option.

Custom designed hopper solutions that suit specific application requirements are also available.

Discharge of materials from the Eco-hopper may be direct to a belt conveyor for a fixed installation. In this case, the bulk material is reclaimed by a gravity discharge unit which feeds the material onto the conveyor at the required output rate.

By using a dust controlled loading spout, the hopper can discharge direct to tipping trucks, where material is to be moved di-rectly off the port to a remote location.

For handling difficult materials, like wood-chips, one or multiple Samson feeder units

can be integrated with the Eco-hopper, to provide controlled rate feeding of virtually any material.

Eco-hoppers can be rail mounted or bolted to suitable concrete foundations. For appli-cations requiring a higher level of manoeu-vrability, hoppers can be supported on solid rubber filled pneumatic tyres. The combina-tion of fixed and steering axles provides the option of power travel.

This low maintenance system reduces in-vestment and operating costs.

The Samson range of bulk handling equip-ment also includes link conveyors, grab hoppers, surface feeders, radial boom stackers and mobile shiploaders.

The South African truck market continued to battle tough trading conditions during July, as month-on-month sales dropped by 9.12% to 2 622 units. However, the industry is still ahead of 2013’s year-to-date sales, albeit slightly, with a 0.56% growth percentage to conclude the first seven months of the year on 17 760 units.

“As has been the case over the past year, external factors such as slow economic growth, widespread labour unrest, rising interest rates and inflationary pressures, continue to dampen growth in the local truck market,” said Jacques Carelse, man-aging director of UD Trucks Southern Africa. “Against this back-drop, truck sales have been flat, with results across the different segments largely mixed to negative.”

According to the latest combined results released by the National Association of Automobile Manufacturers of South Africa (Naam-sa), Associated Motor Holdings (AMH) and Amalgamated Automo-bile Distributors (AAD), only the Bus and Extra Heavy Commercial Vehicle (EHCV) segments are growing so far this year.

The year-to-date figures show that Bus sales, which come from a low base in 2013, are currently up by a significant 17.63% to 674 units. The EHCV segment is continuing its strong run with a significant credible 8.9% increase to 8 087 units.

However, sales in the Medium Commercial Vehicle segment are 8.18% lower at 6 087 units, while the Heavy Commercial Vehi-cle (HCV) segment is down by 3.99% to 2 912 units.

“Unfortunately, we remain cautious in our outlook for the re-mainder of the remainder of the year and expect some above-in-flation vehicle price increases from some manufacturers,” said Carelse. b

SCANIA FLEET MANAGEMENT – a way forward

Staying in touch with their fleet of trucks is an operator’s biggest chal-lenge. Rising fuel prices, increased environmental awareness and tougher de-mands on driver skills make it necessary for transport operators to have access to more information in order to optimise operations and boost profitability.

As haulage companies and operators come under growing cost pressure and environ-mental scrutiny, they are becoming increas-ingly interested in computer-supported fleet management systems on-board their vehi-cles. Truck manufacturers today are more aware of their customers’ requirements and are in the forefront of providing solu-tions not only to enhance their brand profile but to assist operators to streamline their respective companies by reducing the ele-ment of human error.

Scania, one of the world’s leading truck brands has introduced a Fleet Management system consisting of three definite packag-

es of services to fit the varying needs of individual haulage companies. It is based on a little “black box” called the Scania Com-municator which is installed in every new truck as standard and automatically gathers information from the vehicle, such as fuel consumption, driving style, maintenance re-quirements and braking behaviour. This in-formation is wirelessly transmitted via GPRS to the Scania servers along with its GPS po-sitioning data. Scania is able to analyse the data on behalf of the operator to ascertain the exact condition of the vehicle and its exact location, especially in the event of a breakdown. This system will enable opera-tors to have access to each of their vehicles at all times whilst they are on the road.

The three packages on offer consist of a Monitoring Package which enables the Sca-nia control room to monitor such variables as fuel consumption and emission fluctu-ations for each vehicle and to forward the performance summary of the data to the operator by e-mail.

The Analyses Package enables the trans-port company to carry out in-depth analyses of vehicle and driver performance. Since all data is stored in the Scania Fleet Manage-ment Internet portal, customers can have easy access to the information and down-load in order to compile easily interpreted spread sheets of the fleet performance. Each vehicle and driver can therefore be analysed to a large degree and the results can determine whether, the company re-quires to revise their driver training require-ments, as well ass the improve its mainte-nance levels on the fleet.

Tracking and location of each vehicle is monitored through the Control Package which allows operators to follow their fleet and their drivers. The package also gives the transport company the tools for con-trolling fleet routes in real-time. All vehicles can be tracked on a map and monitored to see if they leave their allotted delivery zone area. b

Kal Tire Mining Tire Group is re-launch-ing TTT – the True Tire Technology system that will considerably improve how mine sites monitor tire temperature and pressure in order to increase safety, tire life, fuel efficiency and mine productivity.

It is a well-known fact that tires are one of the top three operating expenses of a mine site. When they are running at optimal pres-sure – only then will a mine site experience maximum value when it comes to savings and productivity related to this expense.

In order to achieve this, a tire temperature and pressure monitoring system is required that is well-designed, all aspects of it works in all environments, and has web-enabled management and reporting capability.

“After consulting with dozens of mine lead-ers around the world, we did a complete overhaul on TTT’s technology to better meet the needs of today’s mines with sev-eral innovative and unique new features,” says Mike Batka, vice president technology, products and services, Kal Tire Mining Tire Group. “We wanted to give our customers the most functional, user-friendly tire mon-itoring system that will help make mines safer and more profitable. A lot of time and expertise was invested in redesigning most of its features; from how it operates to its web-based monitoring and reporting capa-bilities.”

Highlights of Kal Tire’s new TTT: • Seven configurations with the option to

use WiFi, 3G or a radio frequency network • Real-time monitoring with automatic

refreshes every 30 seconds • Highly accurate, waterproof sensors built

to handle hot and humid conditions • In-cab tablet display for vehicle operators

with GPS and data storage capabilities • Internet accessible, user-friendly dash

board providing one-click access to full fleet reporting

• Online pre-configured reports to provide transparency and consistency.

Unlike any other tire pressure monitoring system for earthmovers, the new TTT offers real-time monitoring in radio frequency. In fact, the new TTT is available in seven dif-ferent configurations to offer a communi-cation channel – 900Mhz standalone mesh

network, 3G/GPRS cellular network and 2.4Ghz Wi-Fi – that’s works for any mine site, whether it’s underground or in a harsh, remote location.

Kal Tire’s TTT vehicle kit has also been up-graded so data is visible to operators on an optional in-cab display – providing an extra layer of safety for the operator as well as people around the vehicle. “Driver aware-ness and safety is crucial,” says Batka. “We wanted to provide operators with a design that would allow them to see what’s hap-pening and react.”

TTT constantly monitors the pressure and temperature of mining tires using its unique sensor patch mounted inside the tire. The sensor is sealed in a golf ball-like cavity of polyurethane, making it accurate and waterproof in tires with liquid additives as well as durable enough for hot and humid temperatures. An antenna sensor mounted under the truck sends data as well as alerts. Managers have easy access to monthly re-ports and tire technicians receive instant, paperless tire maintenance work orders.

On earthmover tires, even minute increases in temperature and air pressure can have big consequences, from lost fuel mileage and tread wear to blowouts and pyrolysis. That’s why it was important to Kal Tire that the new TTT offer real-time data.

Unlike some TPMS systems that update ev-ery five minutes, TTT updates data in the cab, and on an online dashboard, every second,

refreshing automatically every 30 seconds. This provides immediate indication if there is an issue – rather than a situation where a system has a 5-minute refresh and a ve-hicle has travelled several kilometers before the issue is known. That’s the difference between saving a tire and a blowout. If you save one tire with TTT, it has paid for itself.

“The benefits are substantial,” says Batka. “Investing in TTT can quickly be offset by extending the life of a tire, reducing tire-re-lated fleet down time, and improving fuel efficiency.”
