Abstract
A mobile shaft winch, includes a carrier vehicle having a vehicle drive, with an internal combustion engine, a rigid main frame, and a rotary platform arranged on the main frame by a rotary connection. A drum winch is arranged on the rotary platform and has a cable drum driven by a winch drive. A hydraulic system arranged on the carrier vehicle includes a hydraulic pump driven by an electric motor a pressure side of the hydraulic pump is in fluid-conducting connection with a hydraulic motor of the winch drive. The internal combustion engine of the vehicle drive drives an electric generator through an auxiliary output drive. The electric motor is configured to be selectively operated on an electricity supply grid or the electric generator.

1-15. (canceled)
A mobile shaft winch, comprising:
- a carrier vehicle with a vehicle drive, a rigid mainframe, and a rotary platform arranged on the rigid mainframe by a rotary connection, the vehicle drive including an internal combustion engine and a transmission;
- a drum winch arranged on the rotary platform and including a cable drum holding a conveyor cable and driven by a winch drive, the cable drum configured to wind and unwind the conveyor cable, the winch drive comprising a hydraulic motor;
- a hydraulic system arranged on the carrier vehicle including a tank configured to hold hydraulic fluid, and a hydraulic pump driven exclusively by an electric motor, the hydraulic pump having a suction side in fluid-conducting connection to the tank and a pressure side in fluid-conducting connection with the hydraulic motor, wherein the hydraulic motor is driven only by the hydraulic pump;
- and
- an electric generator driven by an auxiliary output drive of the internal combustion engine, the auxiliary output drive being a selectable shaft at an auxiliary output of the transmission of the vehicle drive,
- wherein the electric motor is selectively operated in a first mode, in which the electric motor is supplied by an electric supply grid, and a second mode, in which the electric motor is supplied by the electric generator.
