Levelling/slope control system: The slope control system (
o
) can be used to reg-
ulate the traction point on 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.
Crossbeams / screed lifting device: The screed lifting device is used to lift the
screed during transportation. The screed's approach angle can be changed using the
eccentric adjustment facility on the crossbeam.
Depending on the paving condition requirements, the crossbeam can be moved
backwards or forwards. This adjustment enlarges the material space between the au-
ger and screed.
Automatic paving stop and screed charging/relieving: The automatic paving stop
prevents the formation of any screed marks caused by a stopped screed. When the
paver finisher stops (during a truck change), the screed remains in floating position
and relief pressure is applied, thus preventing the screed from sinking while station-
ary.
The screed relieving device puts a higher load on the traction unit, thus increasing the
traction.
Activating the screed charging device can improve the compacting result under dif-
ferent paving conditions.
