The disclosure relates to a work machine, in particular crane, comprising a cable winch, by means of which a cable can be wound up for lifting a load and unwound for lowering the load, a motor, by means of which the cable winch can be driven, and a controller, by means of which the motor can be controlled, wherein the motor comprises a braking device for generating a braking torque counteracting an externally generated torque. According to the disclosure, when the load is lowered as a function of a predetermined target braking torque and a braking torque that can be provided by the motor, the controller is configured to control the braking device and to control the motor in such a way that the load is lowered at a predetermined and, in particular, constant speed. The disclosure also relates to a method for lowering a load by means of a work machine according to the disclosure and to a corresponding computer program product.
