Abstract: The present invention relates to a hoisting winch, in particular to a hoisting gear winch, having a hoisting drum whose winding region is bounded by two lateral flanged wheels, wherein at least one further flanged wheel is provided between the lateral flanged wheels for dividing the winding region into at least two part winding regions, wherein the cable can be guided beyond the named further flanged wheel into the at least two part winding regions. It is suggested in accordance with the invention to move the hoisting drum and/or a transverse cable guide arranged in front of the hoisting drum transversely to the longitudinal direction of the running in/running off cable approximately in the longitudinal direction of the drum and/or to adjust the angular position of the hoisting drum transversely to the longitudinal direction of the drum with respect to at least one transverse axis.

Abstract: The present invention relates to a hydraulic unit with a housing in which a hydraulic converter is accommodated, which is coupled with a drive shaft that includes a connecting shaft piece located outside the housing for connection to a mechanical drive element The invention furthermore relates to a hydraulic driving device with such hydraulic unit and to a drive train connecting piece to which the hydraulic unit is connected. It is proposed to integrate a clutch for connecting and disconnecting the hydraulic unit into the hydraulic unit itself, so that a mechanical drive train, to which the hydraulic unit is connected, can remain unchanged or need not especially be adapted to the clutch. In accordance with the invention, a clutch for coupling and uncoupling the connecting shaft piece of the hydraulic unit to and from the hydraulic converter of the hydraulic unit is accommodated in the housing of the hydraulic unit.

Abstract: The present invention relates to a drive for reaching a desired position of a component such as of a rotor blade, a crane tower, a superstructure and the like, having at least two drive elements that are in toothed engagement with one another and of which at least one is drivable from a drive source and the other is connectable to the component, and having a lubricating device for lubricating the drive elements, wherein at least one lubricant passage for the supply of lubricant to a meshing tooth pair is led through one of the drive elements. It is proposed to effect the supply of the lubricant by a distributor that is connected upstream of the lubricant passage integrated in the drive element and to control the connection between a supply passage of the distributor and the at least one lubricant passage integrated in the drive element by a relative movement between the drive element and the distributor.
