Abstract (en)
[origin: EP3438469A1] The invention discloses a pivot arm device comprising a pivot arm rotatable about an axis of rotation. For rotating the pivot arm a hydraulic cylinder is provided. The latter comprises a piston including a first effective area to which pressure medium can be applied in the raising direction of the pivot arm and including a second effective area to which pressure medium can be applied in the lowering direction of the pivot arm. Moreover, the piston includes a third effective area to which pressure medium can be applied in the raising direction and which serves for load compensation.
