Rope winch

A hoisting gear winch, comprising:

• a hoisting drum having a winding region bounded by first and second lateral flanged wheels, with at least a third flanged wheel provided between the first and second lateral flanged wheels, thereby dividing the winding region into at least two part winding regions,
• a cable run-in control apparatus, and
• a detection device which detects a cable run-in deflection angle,
• wherein a cable is configured to be guided beyond the third flanged wheel into the at least two part winding regions,
• wherein the hoisting drum is axially adjustable in the longitudinal direction of the drum, and the cable run-in control apparatus is configured to set at least two axial positions of the hoisting drum for the winding/unwinding of the at least two different part winding regions, respectively,
• wherein the cable run-in control apparatus axially adjusts the hoisting drum continuously or stepwise depending on the cable run-in deflection angle,
• wherein the cable run-in control apparatus is configured to control the axial displacement of the hoisting drum such that, in each of the at least two different part winding regions, the cable is separately wound into a plurality of cable layers,
• wherein the cable run-in control apparatus is configured to control the axial displacement of the hoisting drum such that, in each of the at least two different part winding regions, the hoisting drum is positioned at a plurality of axial positions,
• wherein the third flanged wheel includes a cable guide channel having a run-in which is an end of the cable guide channel opening to a first winding region of the at least two part winding regions and a run-out which is an end of the cable guide channel opening to a second winding region of the at least two part winding regions, and
• wherein the run-in of the cable guide channel is provided at a height corresponding to a topmost winding layer of a first winding region of the at least two part winding regions and the run-out of the cable guide channel is provided at a height corresponding to a lowermost winding layer of a second winding region of the at least two part winding regions.
