A compensating device (200) maintains specifiable target positions of a load (206) handled using a cable hoist (202) and attached to a cable (216) of the cable hoist. The respective specifiable target position of the load may change unintentionally to an actual position deviating from the target position. The compensating device has a sensor device (240, 242) for detecting the respective actual position of the load (206). A rotational drive (226, 228, 230) specifies a cable length of the cable hoist (202). A controller (244) changes the cable length after the respective actual position has been detected until the load (206) re-assumes its target position. The respective drive (226, 228,230) can be controlled at least partly by a hydraulic motor (226, 228, 230) with opposite rotational directions. The motor is connected to an actuating device (246) having at least two separate pressure chambers (250, 252) with pressure levels that differ during operation, thereby forming a drive section (248) for the respective hydraulic motor (226, 228, 230), and which can be actuated by the controller (244).
