Abstract (en)
[origin: EP1118580A1] The device has a control and regulating unit connected to a controllable winch drive and an evaluation device connected to sensor elements and the control and regulating unit. The sensor elements are pressure sensors that detect the maximum pressure on a changeover valve (16,20) between right and left drive supply lines (6,8). The evaluation unit derives a demand value that controls the winch drive via the regulating unit.
