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.
Drive unit: Both caterpillar drives are directly driven by separate drives. They operate
directly, without any drive chains which require maintenance or servicing.
The tension of the caterpillar chains can be readjusted using tensioners.
A swivelling lane cleaner (
o
), which ensures an even passage during paving, is lo-
cated in front of each of the drive units. Small obstacles lying in the lane are cleared
away to the side.
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 hydraulic motors drive the caterpillar chains via planetary gears that are
mounted directly inside the drive wheels of the caterpillar chains.
Steering system/operator's platform: The independent hydrostatic travel drives al-
low the paver finisher to be turned on the spot.
The electronic synchronisation, controlled from the operating panel, ensures that the
paver finisher runs straight ahead.
The movable operating panel can 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.
