The mobile recycler – always reaching its goal fast

Recycler / Stabilizer WR 2000

WR 2000 – a winner in its class, and becoming indispensable

The WR 2000’s working width of 2 m and working

depth of 500 mm make it the smallest model in the

range of powerful Wirtgen cold recyclers and soil stabilizers.

Nevertheless, there is no need at all for it to hide away from

the big jobs. Quite the opposite is true: Its broad range of

applications, economical mode of operation and free-view

concept are application-related advantages that make the

WR 2000 stand out favourably against comparable machines

in this market segment. The machine’s hallmark, however, is

its exceptional mobility: As it is easily and quickly transported

from one job site to the next, the compact WR 2000 is

available for many jobs on different job locations.

Compact transport dimensions enable the machine to

be transported between job locations without requiring

a special permit.

The operator’s platform can be displaced laterally

beyond the machine edge, providing an optimum

view of the operating area.

The WR 2000 doesn’t show the slightest signs of weak-

ness even in difficult terrain, owing to its all-wheel drive

and individual wheel suspension at the machine frame.

Hydraulically adjustable lifting columns guarantee

maximum ground clearance at all times.

Manoeuvrable andeasy to transport

Always up to the mark with 4-foldlifting column design

Its sturdy machine frame is the made-to-measure suit

of our cold recycler and soil stabilizer WR 2000. It is

ideally tailored for excellent all-terrain mobility and large

ground clearance. The four wheels are suspended individually

at the frame, and the machine can be levelled to the required

height via four hydraulically adjustable cylinders. The milling

and mixing rotor can be adjusted via a massive crank, while

the rotor housing is rigidly attached to the chassis.

Flexible operator’s platform providesbest possible view

The ingenious free-view concept implemented in

the WR 2000 fully satisfies even highest demands.

The operator’s cabin can be displaced far beyond the right

edge of the machine at the mere push of a button. Com-

bined with the fully glazed cabin, this feature provides a full

view of the surrounding area of operation and in particular of

the milling edge. Expensive additional work steps that would

normally be required in difficult sections can therefore be

reduced to a minimum.

Free view even in tricky situations

to events on the job site

Ergonomics is high on our list of priorities

Wirtgen’s design engineers have taken the offensive

yet again with the ergonomical design of the WR 2000.

All control elements in the recycler’s cabin are arranged per-

fectly and in an ergonomically optimized manner. The clearly

structured Cockpit Graphic Centre (CGC) is located within

the operator’s immediate field of vision and is height-ad-

justable. The steering wheel can also be adapted individually

in height and tilt. But there’s even more: The seat console

with related instruments and CGC can be swivelled by up

to 90°. All these features help to tailor the workplace to

accurately fit the needs of the machine operator.

Superior equipment makes easy work

The swivelling seat console permits the machine

operator a free view to the rear while maintaining an

ergonomic sitting position.

All important control elements are located in the

left-hand armrest.

The air-conditioning and heating systems ensure

convenient working in the cabin, independent of

weather conditions.

The cabin’s soundproofing protects the machine

operator against any unwanted engine noises.

Perfect handling, single-handedly

Manoeuvrable and compact: two highly effective features

The WR 2000’s compact design holds lots of potential.

Its transport height of 3 m, width of 2.55 m and low

weight enable the machine to be transported from one job

location to the next quickly and easily on a low-loader. A

particular highlight: The machine does not require a special

transport permit, which pays off in higher daily production

rates instead of annoying and time-killing authorization proce-

dures. Yet another ace is the recycler’s manoeuvrability and

excellent all-terrain mobility. Different steering modes underline

its exceptional manoeuvrability. It can for, instance, be steered

with the front axle, the rear axle, in crab mode or in the

so-called “co-ordinate mode” where both axles are steered.

Goes on every type of low-loader

10 // 11

As transport poses no problem, the machine is

moved to the next job location quickly and is thus

utilized efficiently at all times.

Owing to its outstanding manoeuvrability, the WR 2000

presents itself at its best when approaching obstacles

or when working in narrow bends.

Different steering modes are available and can be chosen

in accordance with the type of work to be carried out.

The machine’s compact design and low height provide

the operator with an even better view of the work area.

Mobility guaranteed

Coming on strong: turning radius of less than 4.50 m

Superior ease in open ground

The WR 2000 always wins the upper hand when work-

ing in open ground. Its powerful, permanent all-wheel

drive prevents the stabilizer from getting bogged down even

when working in deep or soft soils. We have additionally

equipped the machine with hydraulic lifting columns to en-

sure large ground clearance. All four wheels are suspended

to the machine frame individually and can be adjusted in

height independently. In this way, the machine can always

work “in balance” or with the desired inclination. Additionally

supported by a hydraulic differential lock, the WR 2000

demonstrates perfect traction properties and is thus the

ideal partner in difficult terrain.

All-wheel power prevails in muddy terrain

clearance

Their elevated position prevents the working cylinders

from getting soiled, which ensures improved operational

readiness.

The recycler is equipped with finger-light hydraulic all-

wheel steering, enabling it to be manoeuvred easily

even in extremely confined conditions.

The machine’s excellent traction meets all demands,

in particular in soil stabilization.

Large anti-skid wheels support the machine’s

outstanding all-terrain mobility.

These tyres go through thick and thin

The WR 2000 meets evenextreme conditions

Variable mixing capacity – an ingenious recipe for success

One feature speaking in favour of the WR 2000 that

carries a lot of weight with experts is the recycler’s

variable mixing chamber. It meets a requirement which is of

crucial importance for both cold recycling and soil stabiliza-

tion: All construction materials must be mixed very thoroughly

as only a homogeneous mix will be able to meet the high

demands placed on high-quality base layers. The basic

principle is as ingenious as it is simple. The housing of the

milling and mixing rotor is rigidly attached to the chassis.

The volume of the mixing chamber above the rotor increases

automatically to the same extent that the rotor penetrates

the ground below.

Consistently high quality, irrespective of the working width

14 // 15

The variable mixing chamber can be relied upon to

prevent production losses caused by obstructing mix.

The crusher bar at the front supports thorough granula-

tion and prevents slabs from breaking out of the asphalt

pavement.

The scraper blade can be guided conveniently to ensure

thorough mixing.

The scraper blade can be locked at any given height

or can be pressurized and made to glide on top of the

recycled ground in a floating position.

Mature milling technology produceshomogeneous mixes

All recyclers made by Wirtgen feature a powerful

milling and mixing rotor which guarantees that even

extremely heavy soils are mixed thoroughly and homoge-

neously. Naturally, the same also goes for the WR 2000.

The recycler’s high-performance rotor is driven by a direct

mechanical drum drive which is, in turn, powered by a

robust 6-cylinder straight diesel engine. This tried and

tested design, which avoids deflection points and friction

losses, is reflected in consistently high efficiency.

Optimum mixing generates high bearing capacity

16 // 17

Four different rotor speeds enable the machine operator

to choose the speed most suitable for the job at hand.

The power belt absorbs any peak loads and guarantees

low susceptibility to damage.

The WR 2000’s centre of gravity is located favourably

close to the rotor, thus providing a high load that results

in high productivity.

The rotor permits milling in both up-milling and down-

milling mode in accordance with the recycler’s direction

of travel.

Quick-change toolholder system HT11reduces operating costs

The WR 2000 is fully geared to meet all challenges in

field operation. Both the intelligent arrangement of the

tools on the rotor and the ingenious tooling of the rotor

edges boast excellent milling power. The cutting tools are

highly wear-resistant and impress with their exceptional

durability and penetration capability. Replacing cutting tools

quickly: Useful options, such as the combined pneumatic

cutting tool driver and extractor or the hydraulic drum turn-

ing device, support the machine operator and help to speed

up his work considerably. The patented quick-change tool-

holder system HT11 keeps operating costs low, thus ensuring

an even more economical operation of the entire machine.

Working like a clockwork with tried and tested technology

18 // 19

The quick-change toolholder system HT11 is available

as an option but should be a “must” in any specification

because of its high efficiency.

Different cutting tools are available for the different ap-

plications of the cold recycler, underlining the benefits of

the quick-change toolholder system.

The cutting tools are of particularly robust design, which

makes them ideally suited for the toughest applications.

The milling drum provides good access to facilitate the

replacement of cutting tools, which is carried out swiftly

using standard tools.

Perfect mixes without any ifs, ands or buts

Precise metering of the binding agents is of crucial im-

portance for a consistently high quality of the mixing

results. Metering is effected via high-quality microprocessor

units, and the binding agents are then added to the mix by

means of robust injection systems. The recycler can

process water, bitumen emulsion or foamed bitumen, which

are delivered in tanker trucks coupled to the recycler and are

transported to the injection systems via hose connections.

All components transporting the hot bitumen that is required

for the production of foamed bitumen are, of course, heated.

In this way, all components have the required temperature

all the time, and flushing the system is not necessary, which

saves time and money.

Intelligent technology ensures precise metering

20 // 21

The injection systems can be adjusted to the required

width when injecting the binding agents so as to

precisely match the mixing width.

The integrated water tank – which is an exceptional

feature in this machine class – supplies the water

needed for the foamed bitumen production.

An additional water tank with a capacity of 600 litres

(optional) supplies water for the production of large

quantities of foamed bitumen.

The injection nozzles are cleaned automatically,

ensuring permanent operational readiness.

Top quality, always

Smart details save money and make easy work

The WR 2000 surprises with a wealth of practical func-

tions that are reflected in considerable overall time and

cost savings – day after day. One strong point, for instance,

is the fact that the wheels on the right side, which is the zero

clearance side, travel inside the working width, enabling the

recycler to mill flush to kerbs or walls. This clearly is worth-

while. Precise milling flush to kerb and a full view of the

milling edge dispense with costly manual reworking.

Yet another highlight: The WR 2000 features various steering

modes, enabling it to work in both directions of travel.

The advantages of this feature are obvious, since idle runs

or turning manoeuvres are avoided.

Cost advantages are in the details
