ABSTRACT:
The invention concerns a hoisting device with a drive unit (1) including a motor and a transmission, a drive shaft (2) which can be driven by the drive unit (1), with drive flange (3) which can be secured to it, as well as a cable drum (4) which can be connected to the drive flange (3), wherein the torque of the drive shaft (2) can be transmitted by a coupling to the cable drum (4), wherein the coupling consists of at least one coupling element (9) arranged essentially by form fitting between the drive flange (3) and the cable drum (4), being constructed from individual coupling segments (9a), which have drive cams (10) pointing radially inward and outward on both sides, which engage with corresponding recesses (11) of the two adjoining structural parts (3, 4) that can be coupled together for the torque transmission.In order to create a hoisting device whose coupling reliably equalizes the alignment errors with a simple and space-saving construction, the invention proposes that the coupling segments (9a) be arranged on the drive cams (10) and extend essentially between the drive flange (3) and the cable drum (4).
