Abstract (en)
[origin: EP1475347A2] The cable winch system has a cable winch (22), a winch drive (24) and a control unit (21). By the control unit a first operating mode for a lifting and lowering can be set, and a second operating mode in which a load is adjustable on the winch cable. The winch drive has a hydraulic motor connected via hydraulic lines to at least one pressure energy source (20). Piloted valves (9,10,13,14,19) are controlled through the control unit. At least one pressure sensor is installed in the hydraulic lines for measuring of a hydraulic pressure and is connected to the control unit. An independent claim is included for a method for the operating of a cable winch system.
