Abstract:
A method for operating a winch and a winch having a winch drum for spooling a spoolable medium, wherein the winch drum is rotatable about a first axis, a guiding member for guiding the spoolable medium, wherein the guiding member is movable along a second axis between two end positions, and an electric drive having a first electric motor for driving the guiding member towards one of the two end positions during spooling in or spooling out of the spoolable medium. The electric drive is configured to change the driving direction of the guiding member when a monitored torque of the first electric motor, or a quantity indicative thereof, exceeds a predetermined threshold.
