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.
