Base frame for a cable winch having removable support members

摘要

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.

主权项

1. Cable winch, having a base frame comprising a first base plate and a second base plate, at least two longitudinal beams comprising a first beam end and an opposite second beam end, said beams spacing the first and second base plates and keeping them at a spaced disposition with respect to each other,
wherein the first base plate includes blind holes formed on an inner side of the first base plate by a combination of through-openings on the first base plate and a holding element releasably closing the through-openings, and wherein the second base plate includes blind holes formed on an inner side of the second base plate, and wherein in the operating state of the cable winch the first beam ends are inserted and attached in the blind hole openings of the first base plate and the second beam ends are inserted and attached in the blind hole openings of the second base plate, wherein a cable drum is mounted at both ends between and on the inner sides of the base plates, a rotational axis of the cable drum being orientated in parallel with a longitudinal axis of the longitudinal beams, 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 cable winch and the first base plates is so formed that the longitudinal beams are inserted or removed, in conjunction with assembly, disassembly or conversion of the base frame, in the direction of the longitudinal axis thereof and through the through-openings in the first base plate for the passage of the longitudinal beams in conjunction with the assembly or disassembly of the base frame, and wherein the holding element is attached to an outer side of the first base plate, with the holding element comprising a holding bore into which the first beam end protrudes, and wherein the first beam end is fixed to the holding element via a fastening element.
