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 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.
When using ratchets for height adjustment, 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 operating panel by means of
hydraulic cylinders (o).
Auger segments of different lengths can be attached to easily adapt to the different
paving widths.
Levelling/slope control system: The slope control system (o) allows the traction
point to be regulated at the left-hand or the right-hand side with a defined difference
to the opposite side.
To determine the actual value, the two traction crossbeams 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 crossbeam (traction roller), the pav-
ing thickness 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.
