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. 10.5 t.
To facilitate emptying and achieve even material transfer, each of the lateral covers
of the hopper can be hydraulically folded in.
The hydraulic front hopper flaps (
o
) ensure that no material remains at the front of
the feeding hoppers.
The hopper is designed as a "Thermal Hopper" and lengthens the cooling down pe-
riod for the material.
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 is reg-
ulated fully automatically.
The drive is reversible.
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 function is switched on or off by 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.
Auger segments of different lengths can be attached to easily adapt to the different
paving widths.
The auger height is adjusted mechanically.
In another version, the height is adjusted by hydraulic cylinder (
o
).
