Abstract
This disclosure relates to an endless cable winch including a drive unit having an engine configured to generate a torque. The endless cable winch further including an output unit connected to the drive unit, the output unit including a power transmission assembly coupled to the drive unit, the power transmission assembly configured to apply a driving force to a cable. The endless cable winch further including a lifting force limiting device configured to stop the drive unit as soon a predetermined driving force is exceeded. In doing so, this system is also transferable to winches with multiple engines. The engine and the output unit can be movable relative to one another, and the lifting force limiting device can be configured to stop the drive unit based on the relative movement of the drive unit and the engine.
