Hydraulic system: The diesel engine drives the hydraulic pumps for all main drives
of the paver finisher via the attached distribution gear and its auxiliary drive shafts.
Traction 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 Danfoss-Orbitrol steering
ensures easy maneuverability.
The operating panel can be secured in a position at the left-hand or the right-hand
side of the paver finisher by means of a latch accessible from above.
Push roller cross bar: The push rollers for material trucks are fastened to a cross
bar that is pivoted at its center.
This cross bar allows to compensate for different distances to the rear wheels of ma-
terial trucks. The paver finisher thus deviates less from its course and paving in
curves is made easier.
Material compartment (hopper): The hopper inlet is equipped with a conveyor sys-
tem that empties the hopper and transfers the material to the auger.
The hopper can hold about 13.0 t.
To facilitate emptying and to improve material transport, each of the lateral covers of
the hopper can be hydraulically moved (option).
The hydraulic front hopper lids (
o
) ensure that no material remains at the front of the
feeding hoppers.
Material transfer: The paver finisher is equipped with two conveyors driven sepa-
rately that transfer the material from the hopper to the augers.
By scanning the filling height during the paving procedure, the transfer amount or
speed is regulated fully automatically.
Augers: The augers are driven and actuated independently from the conveyors. The
left-hand and the right hand half of the auger can be controlled separately. The drive
system is fully hydraulic.
The conveying direction can be changed towards the center or towards the outside.
This ensures that there is always a sufficient supply with material even if an excessive
amount of material is required at one side. The auger speed is continuously controlled
by sensors that monitor the material flow.
