A paver machine includes a screed arranged to level out road material disposed on the ground and a pressure actuated screed lifting cylinder arranged to lift and lower the screed with respect to the ground. A pressure sensor is arranged to measure the pressure in the cylinder when the screed is being lifted or lowered. Further a control unit configured to receive pressure data from the pressure sensor indicative of the pressure in the screed lifting cylinder when the screed is being lifted by the screed lifting cylinder. Based on analysing the pressure data, the control unit sets a reference height position for the screed.

Paver machine and a method for paver screed height calibration

The invention relates to a road paver comprising a chassis that carries a driver's cab, an undercarriage, at least one drive assembly, a hydraulic system, a cover mounted in an articulated manner, an asphalt feed arrangement comprising a storage hopper, a longitudinal conveyor device which conveys material from the storage hopper to a cross-distributor, and a steam suction system which is operated by means of a vacuum generator and comprises at least one suction flow path whose withdrawal line comprises a suction inlet above the cross-distributor and an outlet at a height above the driver's cab. At the suction inlet-side end of said withdrawal line, at least one confuser-like inlet nozzle is provided which is arranged to be secured to, and movable with, said cover, and which aspirates behind the cross-distributor in the travel direction such that accessibility in the region above the cross-distributor is not affected and the view out to the cross-distributor from the driver's cab is not obscured.
