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 was designed as a tandem swinging 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.
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 travel drive pumps are connected to the
travel drive engines by means of high pressure hydraulic hoses.
These oil engines drive the drive wheels via planetary gears.
The multi-stage planetary gear covers the various driving ranges and the
braking function.
Steering system/operator's platform:
The fully hydraulic steering system ensures
easy manoeuvrability.
The small turning radius permits quick and easy manoeuvring.
The seat consoles left/right can be moved beyond the 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 crossbar
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.
Push roller damping (
o
) hydraulically absorbs the shocks between the material truck
and paver finisher.
