Abstract
The invention relates to a rotary drive for a drum in a winch on a support frame, which has a fluid-operated rotary piston motor that has a housing and a shaft. There are reversible freewheel couplings in a force-transfer path between the motor housing and the support frame and in a force-transfer path between the motor housing and the drum with which the motor housing can be connected to the support frame and the drum for transfer of forces. There are reversible freewheel couplings in a force-transfer path between the shaft and the support frame and in a force-transfer path between the shaft and the drum with which the shaft can be connected to the support frame and the drum for transfer of forces.
Claims14
A rotary drive, in particular a winch drive, for a drum, in particular supported on a frame, the drive comprising:
- a fluid-operated rotary piston motor that has a housing and a shaft, wherein,
- reversible freewheel couplings are in a force-transfer path between the motor housing and the support frame, and a force-transfer path between the motor housing and the drum, with which the motor housing can be connected for a transfer of force to the support frame or the drum, and
- reversible freewheel couplings are in a force-transfer path between the shaft and the support frame, and a force-transfer path between the shaft and the drum, and wherein the shaft can be connected for a transfer of force to the support frame or the drum.
