Basic design

The W 2200 is a road milling machine with mechanically driven milling drum and a two-stage front loading conveyor system, which can be adjusted in height and slewed to both sides. The machine travels on crawler tracks.

engine speed or filling level of the diesel tank can be accessed here, too.

The hydraulic system is additionally monitored by two pressure gauges which indicate the current pressures in

12 different areas of the hydraulic system.

The air filters and the filters of the hydraulic system are monitored electrically.

Chassis

Robust welded construction with mounts for the individual function modules and superstructures. The tanks for diesel fuel and water are integrated into the chassis.

The hydraulic fluid tank forms a separate unit.

The hydraulically opening engine cowling, wide opening servicing doors left and right, and optimum arrangement of the individual components ensure easy access for maintenance and servicing.

Operator’s platform

The walk-through operator’s platform with access ladders left and right is located at the centre of the machine.

It is equipped with two identical control consoles which can be pivoted and adjusted in height. Both control consoles and the right-hand driver’s seat can be shifted sideways beyond the edge of the machine.

The operating elements are located within easy reach and within the operator’s field of vision.

The operator’s platform includes a display of the Wirtgen information and diagnosis system for monitoring the operating status of the machine.

The ergonomic sitting position, clear overview and elastically supported footboards of the operator’s platform help to make the operation of the machine simple and convenient.

Steering and advance speed are governed by means of electrical proportional control and are operated via joysticks.

Power unit

The machine is driven by a modern V 12 engine with a power rating of 671 kW / 913 PS.

The engine complies with the stringent requirements of the exhaust emission standards stipulated by the

US Environmental Protection Agency (EPA, Tier I).

It is equipped with a fully electronic engine management system which allows the engine to automatically adapt to varying ambient conditions, such as changing atmospheric pressure, temperature or humidity.

In addition, the engine offers maximum torque stability even at extreme engine loads, thus preventing breaks in operation.

An extremely large cooler surface effectively cools the engine, thus allowing the safe operation of the machine even at high outside temperatures.

The cooling system is additionally equipped with a fan controller. The fan speed is reduced at low ambient temperatures or low loads, thus reducing the noise emission levels.

Soundproofing

Noise levels are reduced by the standard soundproofing which protects both the operating personnel and the environment against any nuisance due to noise.

Wirtgen information and diagnosis system and instruments

The Wirtgen information and diagnosis system WIDIS 32 provides the operator with quick and comprehensive information on the current status of the engine and the hydraulic system, generating visual and audible alarms, if necessary. Data and messages are indicated on a multi-functional display (LC display) at the operator’s platform. Other information, such as operating hours,

Milling drum drive

The milling drum is driven mechanically by the diesel engine via a mechanical clutch and power belts acting on the drum gearbox. Three power belts with five ribs each ensure optimum power transmission due to their width, and have a long service life. The tension of the power belts is automatically maintained by a hydraulic cylinder.

Milling drum

The milling drum operates in up-milling direction. Tool-

4 // 5

holders accommodating the point-attack cutting tools are welded onto the drum body. Special edge segments ensure a clean sharp cut at the edges. Additional ejectors ensure that the milled material is efficiently transferred to the primary conveyor. If the milled material is to remain on the ground, a flap at the scraper blade ensures that it is deposited between the crawler tracks.

As an option, the milling drum can be equipped with the patented and established quick-change toolholder system

HT11. With this system, the bottom parts of the toolholders are welded onto the drum body.

The upper parts are secured to the bottom parts by retaining bolts to allow quick replacement.

The speed can be infinitely varied from zero to the high maximum speed. A switchable hydraulic flow divider acts as differential lock and ensures uniform traction even under difficult conditions.

Any speed once driven can be saved in a “Tempomat” speed control and re-set, for instance, after changing trucks.

Automatic power control

The machine is equipped with an automatic power control which governs the advance speed in accordance with the engine load, but can also be deactivated.

Cutting tool replacement

The scraper blade opens hydraulically, thus providing good access to the milling drum for the replacement of cutting tools, which can be carried out in a comfortable working position. Sufficient depositing space for the cutting tool containers is provided at both rear crawler tracks.

Crawler track units / Height adjustment of the machine

The crawler tracks are suspended from the chassis by means of cylindrical columns with hydraulic height adjustment.

The height of each crawler track can be adjusted individually.

The milling depth is set via the two front columns, while the rear crawler tracks act as a full floating axle.

The large stroke provides a large ground clearance, thus facilitating even difficult manoeuvres, such as reversing or loading and unloading the machine onto or from a low-bed trailer.

Steering

The machine has a finger-light hydraulic all-track steering system, which can be operated from both the right and the left side of the operator’s platform.

It is governed by means of proportional control, and the front and rear tracks are steered separately via joysticks.

The steering function is detached from the height adjustment by specially designed steering rings.

Tight locking angles permit an extremely small turning clearance circle.

Four-track steering: The following steering modes can be pre-selected: Crab steering and coordinated steering as well as straight-ahead steering for the rear crawler tracks. The rear crawler tracks can be positioned to zero automatically.

Brake system

Braking is achieved by the self-locking hydrostatic transmission.

The road milling machine is additionally equipped with two automatic multiple-disk parking brakes at the front.

Travel drive

The cold milling machine is equipped with large crawler tracks (5 HD) lined with polyurethane track pads.

Each crawler track is driven by its own hydraulic motor.

The travel drive motors are fed by a common hydraulic variable displacement pump.

The desired tension of the crawler tracks is set and maintained hydraulically.

The crawler tracks are driven automatically, thus dispensing with the need to change between milling and travel gear.

Loading the milled material

Loading of the milled material from the milling chamber on trucks is effected to the front (front loading) by means of a wide conveyor system consisting of a primary conveyor and a discharge conveyor.

A gradation control beam largely prevents the asphalt from breaking into large slabs and simultaneously protects the primary conveyor against premature wear and tear.

The discharge conveyor is covered to prevent clouds of dust from being blown away by the wind and causing a nuisance.

It can load trucks from a great height, is height-adjustable and can be slewed to both sides, thus always allowing an optimum adaptation to the conditions prevailing on site.

The high conveying speed and the 1,100 mm wide,

V-ribbed steep-incline belts ensure that the material is quickly removed from the drum housing.

The entire system is filtered via a return-flow suction filter.

The oil for the cylinder functions is additionally passed through a pressure filter.

Electrical system

24 V electrical system with starter, 3-phase alternator

(100 A) and two 12 V batteries, as well as socket outlets for lamps.

Milling depth control / Automatic levelling system

The milling machine is equipped with an electronic automatic levelling system to control the milling depth.

It is governed by means of proportional control, meaning that changes in the reference plane are compensated quickly and without overshooting of the machine.

The reference planes can be scanned by various methods, for instance, by a wire-rope sensor at the side plates, an ultrasonic sensor on the existing road surface, a grade-line in combination with rotary transducers, or a plane formed by lasers.

A slope control sensor is available as an equipment option; the required connections are included as a standard feature.

The Multiplex system can also be integrated into the automatic levelling system as an equipment option.

It is an equalizing system for longitudinal levelling.

Hydraulic system

Independent hydraulic systems for travel drive, conveyor belts, cooler fan drive, water spray system and setting functions (cylinders). The hydraulic pumps are driven by the diesel engine via a splitter gearbox.

Water spray system

The formation of dust clouds during the milling operation is largely prevented by a hydraulically operated water spray system, which also cools the point-attack cutting tools, thus considerably extending their service life.

The spray nozzles are easily removed for cleaning.

Refilling is required only occasionally due to the generously dimensioned water tank.

Filling

Water is filled via a C-pipe connection or a large filling port.

Diesel fuel is filled via a large filling port.

Safety features

The machine can be securely lashed onto a low-bed trailer or loaded by crane with the aid of lashing lugs.

The comprehensive working and safety lights, together with a freely positionable lamp with magnetic pedestal, provide sufficient illumination, thus ensuring that the machine can be operated safely, even in inclement weather.
