The small all-rounder with a wealth of applications

Cold Milling Machine W 35 DC

The ideal candidate for a wide range of applications

The manoeuvrable W 35 DC proves to be an exceed-

ingly helpful ally on the milling site, for its special hall-

mark – its small dimensions – makes it the ideal candidate

for all those minor but important tasks. And that’s not all:

Useful options, such as loading conveyor, all-wheel drive or

50 cm wide milling drum unit, open up an immense range of

applications to the W 35 DC. Milling small areas for partial

repairs, milling passes, supporting the large milling ma-

chines, and a whole lot more into the bargain: The skilful

small milling machine has just the right answer to all these

challenges.

The W 35 DC is second to none in the 35-cm class

Individual options, such as loading conveyor, all-wheel

drive or FCS, greatly extend the machine’s range of

applications.

The compact cold milling machine W 35 DC is perfectly

tailored to smaller construction projects.

The machine’s speedy operation and convenient size

for transport enable it to work on several job sites on a

single day, depending on the distance.

Small milling machine – big performance

Milling surfaces is part of the repertoire

It is really quite astonishing, just how much the innova-

tive cold milling machine W 35 DC can achieve, in

spite – or perhaps because – of its small dimensions. In ad-

dition to the many minor tasks that the industrious machine

pulls off so well, it certainly also has a say in the economical

milling of surfaces. This is down to the 50 cm wide optional

milling drum. The approximate practical area performance

to be expected can be calculated by subtracting an al-

lowance factor from the idealized performance curve. This

takes account of influencing factors that may reduce the

performance, such as hindrances to the work resulting from

traffic, waiting times for trucks, non-contiguous milling areas

or road fixtures.

4 // 5

The final area performance can be calculated using

an allowance factor that takes account of the job site

conditions.

The allowance factor is between 0.7 for free sections of

road and 0.3 for heavy urban traffic.

The modern engine and powerful mechanical milling

drum drive guarantee full performance up to a milling

depth of 110 mm.

A central item in the requirement specifications of

Wirtgen’s design engineers – and a standard feature in

all Wirtgen cold milling machines – is a state-of-the-art,

high-tech milling drum unit. The W 35 DC is no exception to

this rule, because the advantages offered by such a unit are

obvious: The hydraulically pressurized scraper ensures a clean

milled track and secure intake of the granulated material,

and the edge protectors reliably seal off the drum housing.

It is really not surprising, therefore, that with these features

successful milling is as good as guaranteed.

The machine’s ingenious design permits the flexible use

of different milling drums for different applications.

The machine’s standard milling width of 35 cm can

optionally be extended to 50 cm.

The optional loading conveyor can be retrofitted at any

time for both the 35 cm and the 50 cm wide milling

drum.

Milling drums with a clear-cut profile

Cutting technology is our core competence

The success of the W 35 DC is greatly due to its ma-

ture cutting technology which has proven its worth

time and again in everyday use. Milling drums are replaced

quickly and easily, which enables different working widths

and tool spacings to be used for different milling contours.

All jobs are completed at the optimum milling performance,

and a high-quality milling result is achieved. Converting the

milling drum is simple and can be completed in the shortest

time. Replacing the cutting tools is just as easy. Once the

drum door has been opened, the cutting tools are quickly

replaced on the easily accessible milling drum.

The loading conveyor – an exceptionally useful option

Direct loading boosts performance

Anyone who knows what a strenuous and time-con-

suming job it is to remove the milled material from the

milled track by hand will soon come to appreciate the op-

tional loading conveyor of the W 35 DC. It conveys the granu-

lated material effectively and safely to, for instance, the

bucket of a wheel loader. This dispenses with the uneco-

nomical manual loading of the milled material, immediately

producing a clean milled track that serves as an excellent

base for the machine to travel on when milling the next cut.

The loading conveyor can, of course, be slewed to the left or

right, as it is sometimes ideal to deposit the milled material

in a windrow along the side.

Retrofitting the loading conveyorconverts the W 35 DC into a multi-functional rear loader

The loading conveyor can be mounted or removed by a

single person in next to no time.

The loading conveyor can be retrofitted, provided that

the machine is equipped with the optional hydraulic and

mechanical fittings.

The hydraulic power take-off can alternatively be used

for ancillary devices, such as the high-pressure cleaner

or hydraulic hammer.

The loading conveyor is completely covered, thus

effectively preventing the formation of dust.

The W 35 DC makes the most of its potential in tight spots

The small milling machine is ready and waiting when things get tight

The W 35 DC offers a wealth of features which make it

the ideal choice for tricky tasks in cramped job sites or

passageways. In addition to its compact, space-saving

dimensions and smooth steering, the machine also features

a front wheel with an extremely large steering angle. In this

way, the vivacious three-wheeled machine achieves mini-

mum milling radii, virtually performing pirouettes on the

spot. A prime example of this application is milling around

manhole covers. Another ace up the small machine’s sleeve

when working on loose or slippery ground is its powerful

optional all-wheel drive with hydraulic traction control.

It ensures optimum traction and an uninterrupted milling

operation.

The steering angle indicator on the engine cowling indicates the

position of the front wheel

Minimum spacerequirements

The driver has an optimum view of the milled edge from

the operator’s platform, even with the rear wheel folded in.

The milling depth can be read off a separate depth

scale, even with the rear wheel folded in.

Practical applications include milling along kerbs, walls

or similar obstacles.

The machine’s large ground clearance prevents it from

being damaged, for instance, by kerbstones.

Relaxed working boosts performance

Relaxed working is a prerequisite for achieving top

performance. That is why everything on the spacious

operator’s platform is arranged according to ergonomically

efficient principles. The operating elements offer convenient

control and are located within easy reach and in the driver’s

immediate field of vision. All displays are facing towards

him. In addition to that, the operator’s platform offers an ex-

cellent view of the milled edge, the area in front of the milling

drum, and the entire machine – irrespective of the driver’s

height. The optional folding stand-up seat and adjustable

steering wheel offer plenty of space for the machine opera-

tor’s individual requirements.

Feeling comfortable helps to achieve better results

range, the versatile W 35 DC is equipped with a pow-

erful engine that permits economical milling to a depth of up

to 110 mm. The effective milling performance is realized by

means of the mechanical milling drum drive and resulting

high efficiency. This combination makes for top milling

performance, as well as reliable operation and the resulting

low operating costs.

Special operation in buildings withlimited bearing capacities

Shedding the ballast

The rehabilitation of building floors frequently poses

problems when they possess only limited bearing ca-

pacities. However, the W 35 DC quite literally makes light

work of such an application. Weight slabs mounted in sev-

eral “drawers” inside the machine can simply be removed

individually, thus reducing the machine weight by up to

1,340 kg. Narrow building entrances are also no problem at

all, thanks to the W 35 DC’s slender width.

The supplementary weights can easily be removed

Workshop floors or park decks usually have limitedpermissible loads

The complete set of working lights includes two bright

front headlamps and several additional lamps that can

be used as required.

An additional lamp with long coil cord and magnetic

base can be mounted in any given position on the

machine, as required.

The additional lamps can be fastened on the side and

directed so as to ensure optimum illumination of the

milled track and the milling edge.

In addition to ensuring a good view, the working

lamps also provide increased safety during the milling

operation.

Uncompromisingly simple – this has long been

Wirtgen’s philosophy when it comes to maintenance.

To live up to this reputation, the W 35 DC also has large

hinged service flaps that open wide and offer optimum ac-

cess to inspection and maintenance points from the left and

right. Whether filters, engine, pump or other service points –

everything is checked or replaced quickly and easily.

The machine’s maintenance friendliness also extends to the

comprehensive tool kit that is kept within easy reach in a

lockable compartment behind the ladder to the operator’s

platform.

The W 35 DC is particularly well equipped for the many

minor milling operations

A small milling machine performs important tasks in

many different areas of the milling job site. And it is in-

dispensable too, as it operates significantly more economi-

cally than a large milling machine. Our W 35 DC makes short

work of countless important jobs: Milling tie-ins, milling

around manhole covers or hydrants, cutting slots, rehabili-

tating screed or concrete floors in indoor application, re-

moving road markings, removing pavements at full depth,

transverse milling – the list could be continued indefinitely,

as the machine has a nearly limitless range of applications.

22 // 23

Thanks to its small size and turning radii, the machine is

eminently suitable for all milling operations in extremely

confined conditions.

Slot cutting rings are available for special applications

like, for instance, cutting butt joints or milling along rails.

Other special applications include the production of so-

called “rumble strips” – safety depressions in the pave-

ment shoulder that help to prevent cars from driving off

the road.
