Abstract

A lifting apparatus, especially a cable traction mechanism, comprising a base frame that has at least two base plates, further comprising at least two longitudinal beams which have a first end and an opposite second end and which interconnect the base plates and keep the same apart from each other. The lifting apparatus, especially a cable traction mechanism, comprises a simple design and can readily be mounted, dismounted, or modified by detachably fastening the first end and the second end of the longitudinal beams to the base plates in such a way in an operational state of the lifting apparatus and designing one of the at least two base plates in such a way that the longitudinal beams can be inserted or removed in the direction of the longitudinal axis thereof when mounting, dismounting, or modifying the base frame.

Claims22

Dependent claims

Lifting apparatus comprising a cable winch, having a base frame comprising at least two base plates, having at least two longitudinal beams comprising a first beam end and an opposite second beam end, said beams connecting the base plates together keeping them at a spaced disposition with respect to each other,

wherein the first beam end and the second beam end of the longitudinal beams are so releasably attached to the base plates in an operating state of the lifting apparatus and one of the at least two base plates is so formed that the longitudinal beams can be inserted or removed, in conjunction with assembly, disassembly or conversion of the base frame, in the direction of the longitudinal axis thereof and through one of the at least two base plates for which arranged in a first base plate of the at least two base plates are through-openings for the passage of the longitudinal beams in conjunction with the assembly or disassembly of the base frame.
