Abstract:
Trailing cable winch comprising:an axially stationary, rotating winding arm which is disposed on a carrier tube and driven by a motor arranged in the carrier tube which is capable of depositing a trailing cable on an axially reversibly movable cable drum which is disposed on the carrier tube; wherein the rotation of the winding arm is synchronized with a movement of the cable drum such that, during a linear movement of the cable drum, a linear advance of the cable drum per rotation of the winding arm corresponds substantially to a diameter of the trailing cable, and in an end position of the cable drum, two trailing cable layers are deposited above one another; and wherein in the carrier tube, a multistage planet wheel transmission is arranged which is driven by a motor shaft of the motor and includes a secondary stage which drives a hollow cylinder situated in the carrier tube, a cylinder jacket of the hollow cylinder having a guide groove into which a guiding pin, connected with the cable drum, engages and, when the hollow cylinder is rotated, causes an advancing of the cable drum, the guiding pin being guided in an axial oblong hole in the carrier tube.
