Abstract

A lifting apparatus, especially a cable traction mechanism, comprises a base frame that has at least two base plates and at least two longitudinal beams that interconnect the base plates and are spaced apart from each other. Attachment elements are mounted on the base plates by means of holding parts. The lifting apparatus, especially a cable traction mechanism, is characterized by a modular design, where the holding parts are arranged as extensions of the longitudinal beams.
