The invention relates to lifting gear having a drive unit (), a drive shaft (), which has a drive flange () fixable thereon and can be driven by the drive unit (), and a cable drum () that can be connected to the drive flange by means of a coupling, said coupling comprising at least one coupling element () engaging in a recess () in the drive flange () and in a hole () in the cable drum () to transmit torque. In order to equip a lifting gear having a drive unit comprising a motor and a gearbox with a coupling, which ensures simple assembly with a simple and space-saving design, according to the invention the coupling element () is movable and fixable radially from an assembly position into an operating position, in which the coupling element () connects the drive flange () to the cable drum () in a driveable manner.

Lifting gear

A hoisting machine, such as a cable block, includes a support frame having at least two face plates, which are detachably joined together and spaced apart by at least two longitudinal members. The support frame includes a simple structural design, in which the longitudinal members are detachably joined to the face plates such that the ends of the longitudinal members are pressed against a bearing surface of the face plates in the direction of their lengthwise axis, transversely to the longitudinal member.
