World class in performance and productivity

Cold Milling Machine W 250 i

High-performance cold milling machine – designed with sheer efficiency in mind

No other milling machine is equal to greater challenges in road construction

Maximize productivity while minimizing operating

costs – this maxim is the key for construction projects

that require large pavement areas to be milled at record

speed. Tremendous engine power makes the W 250 i high-

end cold milling machine from Wirtgen a top performer

which completes even the toughest jobs with maximum

efficiency. But the large milling machine has even more to

offer: the WIDRIVE machine management system, which

greatly improves operator comfort, guarantees low fuel

consumption rates while enabling an environmentally

compatible milling process. It goes without saying that,

owing to its innovative dual-engine concept, the W 250 i

is a role model in economy also during phases in which

performance requirements are low.

Unlimited milling performance

Unrivalled in the large milling machine class

Each type of pavement removed by the W 250 i is

instantly crushed into small-sized material by the

top-performing machine at tremendous advance rates as

two ultra-strong diesel engines flex their muscles. Milling

extensive areas on motorways or airports is therefore not

a problem at all. The machine’s intelligent WIDRIVE

management system, state-of-the-art dual-engine concept

and choice of different engine or milling drum speeds are

extremely useful features on such high-profile, large-scale

construction projects: they contribute to significantly

reducing the overall operating costs.

4 //5

Its tremendous engine power makes the W 250 i the

ideal candidate for milling pavements at depths of

up to 350 mm or hard concrete pavements at high

advance rates.

Beyond the highly efficient milling of individual layers,

complete road pavements can also be removed in a

single machine pass.

Optimum organization of trucks enables the W 250 i to

remove up to 1,200 tonnes per hour of asphalt – which

is equivalent to the payload of 60 trucks.

The high-performance W 250 i is the ideal choice also

for large-scale projects that need to be completed on

schedule under tremendous deadline pressure.

Choice of three different milling drum speeds

A clever feature assists the machine operator in

optimizing diesel fuel consumption, milling per-

formance and thus the overall efficiency of the W 250 i:

adjustment of the milling drum speed from the operator’s

platform. It guarantees optimal milling performance levels

regardless of conditions and across a wide range of ap-

plications. The W 250 i usually runs at the medium milling

drum speed when carrying out standard milling jobs, such

as milling a surface course. High speed is selected for the

large-scale milling of thin pavement layers. Low speed is

the right choice if maximum milling performance levels are

to be achieved at the lowest possible cost: it guarantees

reduced fuel consumption rates and low cutting tool wear.

Optimum milling performance – whatever the job

6 //7

A selector switch in the operator’s platform enables

the engine or milling drum to be set to three different

speed levels.

Low milling drum speed is recommended if high milling

performance levels are required at low milling costs,

for instance, when removing complete pavements at

full depth.

Medium milling drum speed ensures a favourable par-

ticle size of the milled material and should be selected

for surface course milling jobs.

High milling drum speed at high advance rates ensures

an excellent surface texture in fine milling jobs.

High-tech – yet easy to operate

Controlling the W 250 i with ease

The innovative operating concept installed in the

W 250 i supports the operator and keeps him up-

to-date on everything he needs to know. The control

panels on the left and right have identical features and are

individually adjustable, thus allowing ease of operation on

both sides of the machine. Together with the LEVEL PRO

control panel, the multifunctional control screen can be

swivelled to both sides to always face the machine opera-

tor. It informs the operator about all important machine and

operation parameters. All controls are located within easy

reach and in the operator’s field of view. They are labelled

in a language-neutral manner and allow easy and intuitive

operation. In the final analysis, the operator is familiar with

the W 250 i very quickly, enabling him to fully focus on the

milling process and deliver top performance.

The W 250 i offers great clarity, a small number of controls and ad-justment to personal preferences

The number of controls has been minimized as the

intelligent WIDRIVE machine control system takes care

of many tasks previously performed by the machine

operator.

The clearly arranged controls are ergonomic in design

and help to prevent fatigue during work.

Ground personnel can use control panels mounted on

the sides of the machine to set or modify important

parameters, such as the milling depth.

Lockable, break-proof covers protect all of the control

panels against vandalism.

Making easy work of any job

The multifunctional control screen provides clear in-

formation on operation parameters and maintenance

details. User-friendly diagnostic tools with clear, unam-

biguous graphic displays enable comprehension of the di-

agnostics procedures after only a short training period. Yet

another feature is the continuous logging of events during

the entire milling process. After keying in the material

density and milling width, the control system automatically

displays information such as the weight and volume of the

material milled, the size of the area milled or the number of

trucks loaded. These job parameters allow the quick and

easy settlement of projects and provide reliable logging of

daily performance.

WIDRIVE – technology designed with people in mind

WIDRIVE is an intelligent machine management sys-

tem. It automatically manages numerous steps in the

control of the W 250 i which normally need to be performed

by the machine operator. WIDRIVE links various machine

functions, such as diesel engines, travel drive, milling drum

drive and conveyor drive, water spray system, automatic

PTS system as well as LEVEL PRO levelling system, thus

enabling the operator, who is relieved of much of his previ-

ous workload, to fully focus on the quality of his work.

The intelligent linking of these machine functions pays for

the customer in terms of signifi cantly reduced diesel con-

sumption rates, faster processes, reduced water demand,

low engine noise levels and increased daily production

rates.

The spacious operator’s platform is fully equipped

to enable ergonomic working in line with practi-

cal requirements and over extended periods of time. The

recessed chassis contour – or so-called “wasp waist”

design – of the W 250 i provides the machine operator

with a full view of the front right track unit, milling edge

and edge protection plates. He also has an excellent view,

in both upright and seated position, of the controls and

everything that is happening on the construction site. The

vibration-isolated operator’s platform is accessed conveni-

ently via access ladders fitted on both sides. It is equipped

with individually adjustable comfort seats, a hot-air blower

and a protective canopy that is fully movable to the left or

right side. All of these features make for perfect working

conditions.

When using six cameras, an additional camera screen

is installed to allow the simultaneous display of two

different camera views.

Two or six high-resolution colour cameras can be

installed in accordance with customer specifi cations.

LEVEL PRO guarantees high-precision milling results

Geared up for the future with state-of-the-art technology

An accurate levelling system is essential for achiev-

ing a perfect working result. Wirtgen has developed

a specific levelling system for use with cold milling ma-

chines: LEVEL PRO. The overall system comprises various

sensors, a controller unit and a separate control panel.

The graphics-enabled LEVEL PRO screen provides a clear

read out of key parameters. Set and actual values for the

left and right milling depth as well as cross slope parame-

ters are clearly shown on the displays as work progresses.

In addition, the memory feature is very useful to program,

store and invoke set values.

“Rapid slope” – the electronic cross slope sensor for the milling

of predefined cross slopes

Displacement sensors in the hydraulic cylinder accurately

capture the milling depth

14 //15

Two lifting cylinders with integrated displacement sen-

sors capture the milling depth at the edge protection

plates on both sides of the machine.

A great variety of sensors can be integrated into the

automatic levelling system, such as hydraulic milling

depth, cross slope and ultrasonic sensors.

LEVEL PRO can be easily extended, for instance, by

the multiplex system, laser levelling, or 3D levelling

which uses the interface included in the system.

The multiplex system analyses the measuring points

of three sensors on each side of the machine – very

useful to ensure perfectly level surfaces.

Unrivalled power – optimized environmental protection

State-of-the-art engine technology

Two separate ultra-performance diesel engines

enable the W 250 i to mobilize unparalleled milling

performance whenever required. In addition to the innova-

tive dual-engine concept, the large milling machine offers

an exceptionally efficient energy balance while keeping

the strain on the environment low. For the two economical

engines can be operated at three different speed levels to

efficiently respond to the specific job requirements. The

fully electronic WIDRIVE machine management system

enables both engines to always work in the optimal perfor-

mance and torque ranges, at extremely low fuel consump-

tion rates and low operating costs.

16 //17

The W 250 i features state-of-the-art engine technology

for lowest environmental emission levels, complying

with the stringent specifi cations of exhaust emission

standards EC Stage 3b / US Tier 4i.

To ensure effective exhaust gas purifi cation, both

engines of the W 250 i are equipped with a two-way

catalytic converter integrated into the diesel particulate

fi lter.

Combined with an effective sound insulation of the en-

gine compartment, the quiet ECO engines guarantee

low noise emission levels.

The operator is protected from vibrations as both

engines are supported and isolated from vibration by

silent blocks.

State-of-the-art dual-engine concept

It takes two to boost economic efficiency

Wirtgen is the first cold milling machine manufacturer

worldwide to offer uncompromising performance

characteristics and maximum efficiency by connecting two

diesel engines by means of a multiple V-belt. Taken togeth-

er, the two engines provide tremendous power, enabling

the W 250 i to achieve unmatched performance levels.

Engine 1 only is in operation in those conditions where the

performance level required to achieve the specified results

is low. This offers significant advantages: deactivating en-

gine 2 results in lower noise levels, lower fuel consumption

and therefore lower exhaust gas emission levels.

18 //19

While engine 1 drives all functional groups, engine 2

is switched on automatically or at the fl ick of a switch

for full milling power.

Engine 2 is switched off automatically in certain situa-

tions, for example, when initiating the transport mode

or when stopping the traction drive for three minutes

or longer.

The operator decides for himself whether to switch off

engine 2 when performing milling operations at partial

load.

Switching on engine 1 only is often suffi cient for milling

off a surface course at a depth of 4 cm.

PTS – always parallel to the road surface

Finely tuned compensation of surface irregularities

Why does the W 250 i always maintain its stability,

whether during the milling process, when simulta-

neously lowering all four lifting columns, when lowering

the rear track units into the milling cut, when altering the

milling depth, in case of surface irregularities on the left

or right side, or when in transport mode? The solution is

PTS. The intelligent automatic system aligns the machine

parallel to the road pavement: any surface irregularities are

compensated dynamically via the machine’s four hydrauli-

cally inter-connected lifting columns. This feature provides

the W 250 i with a high level of stability in both longitudinal

and transverse direction, relieves the operator from the

need for manual adjustment and improves the overall lev-

elling quality. In short – it makes the milling process much

more efficient.

If one of the crawler tracks hits an obstacle (such as an elevated milling edge) during the milling operation, the other three track units contribute to compensating the level offset, thus enabling the level compensation to occur much more rapidly.

20 //21

Large steering angles of the four track units enable surprisingly small turning radii

Crab steering permits the machine to easily approach the milled cut from the side

ISC – the intelligent travel drive system

Narrow radii, accurate and fast steering

manoeuvres

When a large milling machine is required to be highly

manoeuvrable or make swift headway on difficult

ground, the turn of the W 250 i has come. However, this

is attributable not only to the hydraulic all-track steering

system, freely selectable steering modes, suspension units

with separate hydraulic height adjustment or continuously

adjustable travel speed. Add to this the intelligent ISC

track control system. It includes three basic features: an

electronic traction control system to ensure optimal trac-

tion, automatic speed adjustment of the individual track

units in bends to reduce track pad wear, as well as an

optimized advance rate to ensure maximum milling perfor-

mance at all times.

Hard-wearing HT22 quick-change toolholder system included

Wirtgen has continually developed and improved the

milling process in accordance with strict rules. Our

greatest strengths are extensive manufacturing expertise,

knowledge in the use of high-quality, highly wear-resistant

materials and optimal, application-specific positioning of

the cutting tools on the milling drum. The cutting tools

guarantee optimal milling performance, a highly precise

milling texture and low-vibration operation of the machine.

The broad range of different types of milling drums enables

an equally broad range of applications. In addition, the

wear-resistant HT22 quick-change toolholder system

ensures extended, highly effective milling intervals. All in

all, Wirtgen milling drums contribute to significant time and

cost savings in tough everyday operation on the job site.

On the road of success with mature Wirtgen milling technology

22 //23

The HT22 system is distinctive for its exceptionally

high durability, optimized tool rotation and significantly

extended service intervals.

The milling drum turning device moves the milling

drum into the ideal position in forward or reverse mode

with the diesel engine switched off.

The innovative hydraulic tool extractor can be oper-

ated effortlessly with the diesel engine switched off.

Ejectors made of highly wear-resistant steel can be

turned about 180° and thus be used twice.

Wide range of applications with milling widths from 2.20 m to 4.40 m

Cost and quality benefits through XXL-size milling drum units

To fully exploit its tremendous milling potential,

a housing extension enables the W 250 i to be

equipped with milling drums of up to 4.40 m in width.

Milling drum units wider than 2.20 m pay for themselves

quickly through tremendous area performance levels as

they enable wide road pavements to be removed in a

single machine pass. The oversized drum units play their

trump cards in particular on wide urban roads, motorways,

highways and airports. In addition, the milled surfaces

impress with perfect evenness. This results in enormous

saving potentials as a process using greater milling widths

reduces the number of adjacent cuts and of the turning

manoeuvres required while also driving down labour cost.

Milling drum unit with many useful features

Milling flush to kerb right down to the full working depth

An intelligently designed milling drum unit is part of

the W 250 i’s equipment package. For full loading of

the milled material, the operator lowers the scraper blade

hydraulically. When raised and locked at the required

height, the scraper blade enables the milled material to be

either partially loaded or remain in the milled cut. In addi-

tion, the scraper blade can be swung wide open for the

replacement of cutting tools. The edge protection plates

left and right are raised via hydraulic cylinders to precisely

mill along road fixtures. Raising the edge protection plates

also prevents them from digging into the ground in un-

paved areas. To prevent collisions during manoeuvring, the

gradation control beam, scraper blade and side plates are

raised when in transport mode. Yet another extra feature:

in emergency mode, all cylinder functions can be operated

even with the engine switched off.

Set the scraper blade to “float-ing” position to allow full loading

of the milled material

… promotes favourable par-ticle sizes and prevents the

formation of large slabs

The hydraulically lifting gra-dation control beam protects

the belt from damage, …

Lock the scraper blade at the required height for partial loading of the milled material

26 //27

Yet another highlight: the edge protection plate on the

right machine side can be raised by 450 mm.

Accurate milling fl ush to kerb is thus also ensured at

great working depths, enabling the edge protection

plate to move over the kerb for the purpose of level

detection.

Two separate water spray bars ensure optimal tool

cooling, with the water pressure being adjusted in

accordance with the machine’s performance and the

amount of water being continuously variable.

This feature extends tool durability and effectively

reduces the generation of dust.

Accurate milling along kerbs is possible on the right side even at maximum milling depth

Dimensions in mm:

Removing huge amounts of milled material

Reliable material loading even under full load

The powerful W 250 i has been designed for maxi-

mum performance and is therefore equipped with

a conveyor system offering exceptionally high conveying

capacities. The swivel-mounted and height-adjustable

discharge conveyor enables tremendous amounts of milled

material to be loaded onto trucks in the most flexible and

cost-effective manner. This is of advantage in particular

when working in narrow bends or crossroad areas and to

ensure that trucks can change “on the fly”. The conveyor

system can be continuously adjusted to different belt

speeds as required by the milling job.

The loading conveyor fills large dump trucks in record time

Wide conveyor slewing angles of 60° to either side ensure smooth material transport

28 //29

The belt speed can also be adjusted manually to

achieve perfect distribution of the milled material on

the truck by setting a variable discharge pattern.

Optimizing the belt speed guarantees minimum wear

of the belts which have rugged cleat profiles.

Wear of the primary conveyor is minimized as the belt

speed is controlled automatically in accordance with

the load.

A stoplight system integrated in the electrically adjust-

able, fold-in exterior mirrors enables visual communi-

cation with the truck driver without needing to revert to

audible signals.

High belt speed

Low belt speed

Continuously adjustable belt speed and discharge range

Useful for night work: the stoplight system gives silent “Stop” and “Go”

instructions to the truck driver

Vacuum cutting system offers a high level of operator comfort

Innovative extraction technology offers a free view of the milling edge

The health and well-being of the operating crew de-

serve particular attention. The W 250 i can therefore

be equipped with the vacuum cutting system to extract

fine material particles: by creating a negative pressure in

the milling drum housing, the mix of air and water vapour

is evacuated and, via a hose system, fed back into the

flow of the milled material transported on the discharge

conveyor. Better air quality and visibility in the working

environment of the machine operator and ground crew

significantly improve operator comfort and boost staff

performance. In addition, reduced soiling of components

such as the engine or air filter results in savings in the

replacement of spare parts or cleaning of the machine.

30 //31

For peace of mind in operation

The hydraulically opening, hinged engine cowling and

wide-opening service panels on either side ensure full

access to all points of maintenance.

All points of maintenance have been grouped together

and are arranged in a clear pattern, offering convenient

access.

The machine’s automatic diagnostic system indepen-

dently monitors valves, sensors and control compo-

nents.

Ample space is available for storing spare cutting

tools, tool kit, machine equipment and high-pressure

cleaner.

Successful moves in night operation

Wasting no time during night operations

The W 250 i calls it a day only after it has successfully

completed its daily work – which is not a problem at

all even in darkness. The machine puts up an equally com-

pelling performance during the night and in broad daylight.

The lighting system comprises several spotlights and LED

lights offering flexible adjustment options to fully illuminate

the important work areas. Backlit control panels enable the

machine operator to easily control the W 250 i even during

night operations. Not to forget the smart “Welcome” and

“Go home” lights feature: when walking away from the

W 250 i, it fully illuminates the surroundings of the machine.

Excellent lighting enables night operations to be completed quickly and efficiently

Keeping a firm eye on environmental standards

Significant reduction of environmental emission levels

The W 250 i large milling machine performs extremely

hard work, yet also successfully meets the chal-

lenge to comply with ever stricter environmental and health

requirements. Users of the W 250 i have a clear ecological

conscience thanks to the intelligent WIDRIVE machine

management system, for WIDRIVE not only significantly

reduces diesel consumption rates but also minimizes

exhaust gas emissions, noise levels and engine vibrations.

The machine’s dual-engine concept is a vital element of

the WIDRIVE system as it offers the unbeatable advantage

of simply shutting down the second engine, when not

needed, for fuel economy. Exhaust and noise emission

levels are reduced at the same time – to keep the environ-

ment intact.

34 //35

The two engines installed in the W 250 i comply with

the strict specifications of exhaust emission standards

EC Stage 3b / US Tier 4i.

The effective VCS extraction system used to evacu-

ate fine material particles reduces dust emission in the

area of the milling drum housing.

Noise emission is reduced by the efficient soundproof-

ing of the engine compartment and anti-vibration

engine support.

Different engine or milling drum speeds, which can be

selected in line with the milling job, ensure exception-

ally low fuel consumption.

Reduced diesel consumption
