ABSTRACT:
This movement compensation arrangement in one aspect comprises a hydraulic main motor group driven by the pressure difference between two hydropneumatic pressure containers and a hydraulic auxiliary motor group driven by a pump with an effect which can be regulated, and adapted to provide for dynamic compensation. The hydraulic main motor group is adapted to substantially take up the static load. The two motor groups are rotationally coupled to moving means. A control unit in response to input signals controls both motor groups, of which the main motor group has a stepwise and/or continuously variable displacement (FIG. 1).
In another and modified aspect the arrangement comprises a hydraulic motor group also driven by the pressure difference between two hydropneumatic pressure containers and a hydraulic pump having a power output which is able to be regulated and being adapted to provide for dynamic compensation by actuating a hydraulic-mechanical converting unit which moves an element in a movement compensated system. The hydraulic motor group is adapted mainly to take up static load as the axle from the motor group is directly in a mechanical way or indirectly in a hydraulic-mechanical way, coupled to said element. A control unit in response to input signals controls the hydraulic pump and the motor group. The motor group has a stepwise and/or continuously variable displacement (FIG. 2).
