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.
Height adjustment and extension of augers: Height adjustment and extension of
augers ensure optimum adaptation to a wide range of paving thicknesses and widths.
The basic configuration allows the height to be adjusted by attaching chains to the
side arms and by actuating the hydraulic screed lifting device.
When using ratchets for height adjustment (option), barrel nuts at the guide supports
in the rear wall are used to adjust the height.
Another variant allows the height to be regulated at the control panel by means of hy-
draulic cylinders (option).
Auger segments of different lengths can be attached to easily adapt to the different
paving widths.
Automatic levelling/slope control system: The slope control system (option) al-
lows the regulation of the traction point either on the LH or RH sides, by maintaining
a difference defined against the opposite side.
To determine the actual value, the two traction arms are linked with a slope control
rod.
The slope control system always operates in conjunction with the screed height ad-
justment of the opposite side.
By adjusting the height of the traction point of the arm (traction roller), the paving
height of the material or the laying height of the screed can be controlled.
Actuation occurs electro-hydraulically on both sides and can be controlled manually
by means of toggle switches or automatically (by means of an electronic grade control
system).
The screed lifting system: The screed can be lifted to transport height using the
screed lifting system. Lifting occurs electro-hydraulically on both sides by actuating
the hydraulic cylinders on the arms and is controlled by means of toggle switches on
the operating panel.
Automatic screed stop and screed charging/relieving device: The automatic
screed stop prevents the screed marks caused by a stopped screed. When the paver
finisher stops (during a truck change), the control valves set to the floating position
are shut and locked, thus preventing the screed from sinking during the stop.
The screed relieving device puts a higher load on the chassis, thus increasing the
traction.
Activating the screed charging device can improve the compacting result under cer-
tain conditions.
