Abstract
A construction machine is provided, such as a drilling rig having a mast along which a tool is movably mounted. The tool is suspended on a cable actuated by a cable winch for raising and lowering the tool, the cable winch being driven by an electric motor as a winch drive in a drive mode. The electric motor is designed to also operate in a recuperation mode in which the electric motor generates electrical energy when the tool is lowered and outputs the electrical energy to an energy store. A controller is designed to actuate the electric motor depending on a specifiable target value such that the cable is tensioned both in the drive mode and in the recuperation mode of the electric motor.
