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 units 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 adjustable synchronisation, controlled from the operating panel, ensures that the
paver finisher runs straight ahead.
Push roller crossbar:
The push rollers for material trucks are fastened to a cross bar
that is pivoted at its centre.
The finisher deviates less from its course, thereby facilitating paving in curves.
For adaptation to various truck design types, the push roller crossbar can be shifted
to two positions.
The push rollers and the hopper can be swivelled up together to reduce the
transport width.
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 approx. 5.0 t.
To facilitate emptying and achieve even material transfer, each of the lateral covers
of the hopper can be hydraulically folded in.
With the asymmetrical hopper (
o
) a hopper wall can be extended to enlarge
the volume.
Material transfer:
The paver finisher has a conveyor that brings the material from the
hopper to the distribution augers.
By scanning the filling height during the paving procedure, the transfer amount is reg-
ulated 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 centre or towards the outside.
This ensures that there is always a sufficient supply of material even if an excessive
amount of material is required at one side. The auger speed is controlled by sensors
that monitor the material flow.
Height adjustment and extension of augers:
Height adjustment and extension of
augers ensure optimum adaptation to a wide range of paving thicknesses and widths.
