Abstract:
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.
