Engine: The paver finisher is driven by a water cooled diesel engine. For further de-
tails see the technical data and the engine's instruction manual.
Traction unit: The front axle is a tandem swing axle. As the wheels are not mounted
on non-uniform lifting arms, the second front wheel is subject to a heavier load on the
shorter lifting arm.
This solution provides increased steering and load-bearing capabilities, especially on
soft grounds. The tyres are solid rubber tyres at the front axle and large, tubeless,
pneumatic tyres at the rear axle (water filling - o).
With additional front-wheel drive, the second front axle or both front axles can be en-
gaged as additional drive axles.
Hydraulic system: The diesel engine drives the hydraulic pumps for all main paver
finisher drives via the attached distribution gear and its auxiliary drive shafts.
Travel drive: The continuously adjustable traction drive pumps are connected to the
traction motors by means of high pressure hydraulic hoses.
These hydro-motors can drive the drive wheels through a planetary gear.
The multi-stage planetary gear produces the various movement ranges and the brake
function.
Steering system/operator's platform: The fully hydraulic steering system ensures
easy manoeuvrability.
The small turning radius permits quick and easy manoeuvring.
The operating panel can be hydraulically shifted beyond the left/right outer edge of
the vehicle, providing the driver with a better view of the paving area in this position.
The entire operating panel can be swivelled for operation beyond the outer edge of
the vehicle, and can be additionally be locked in several positions along the control
platform.
Push roller crossbar: The push rollers for material trucks are fastened to a cross bar
that is pivoted at its centre. The paver finisher thus deviates less from its course and
paving in curves is made easier.
For adaptation to various truck design types, the push roller crossbar can be shifted
to two positions.
