Levelling/slope control system: The standard paver finisher is prepared electrically
and hydraulically to fit an automatic levelling system.
The levelling system monitors the paving thickness and corrects any deviations from
the nominal level automatically.
The system consists of optional combinations of:
- Height controllers
- Slope controller
- Digital controllers
The slope control system always operates in conjunction with the levelling cylinders
on the opposite side.
By adjusting the height of the traction point of the crossbeam, the paving thickness of
the material or the laying height of the screed can be controlled.
Actuation occurs electrohydraulically on both sides and can be controlled manually
by means of toggle switches or automatically by means of an electronic grade control
system.
Screed lifting device: The screed lifting device is used to lift the screed during trans-
portation. This takes place by hydraulic means by actuating a hydraulic cylinder.
