Lifting device, in particular a cable winch
A cable winch having a base frame with at least two base plates, and at least two longitudinal beams for connecting the base plates to each other. One of the base plates is designed such that the longitudinal beams can be installed or removed in the direction of the longitudinal axis of the longitudinal beams through the base plate, with passage openings in the base plate for feeding the longitudinal beams there through, and with one beam end of each of the longitudinal beams inserted into one of the passage openings. A beam end of each of the longitudinal beams is fastened to the base plate in and against the direction of the longitudinal axis of the longitudinal beam by a retaining element that is fastened to an outer face of the base plate, wherein a separate retaining element is provided for each longitudinal beam in order to enable simple assembly, disassembly, or conversion.
1. A lifting device, said lifting device having a base frame comprising at least two base plates, having at least two longitudinal supports comprising a first support end and an opposing second support end, said longitudinal supports connecting the base plates together and spacing them apart, wherein the first support end and the second support end of the longitudinal supports are detachably fastened to the base plates of the lifting device in such a way and one of the at least two base plates is designed in such a way that the longitudinal supports can be installed or removed in the direction of their longitudinal axis and through one of the at least two base plates, for which purpose passage openings for passage of the longitudinal supports are provided in one of the base plates of the at least two base plates, in each case one support end of the longitudinal supports is inserted and fastened in one of the passage openings and the support end of the longitudinal supports is fixed to the base plate via a retaining element in order to prevent displacement of the longitudinal support along the longitudinal axis in the direction of the two support ends, for which purpose the retaining element is fastened to an outer side of the base plate, wherein the support end of the longitudinal supports has a retaining bore, and the retaining element is fixed to the support end via a first fastening element that engages in the retaining bore, wherein for each longitudinal support a respective separate retaining element is provided, and that, in addition to the first fastening element, a second fastening element is provided by means of which the respective retaining element is fixed to the base plate.
2. The lifting device as claimed in claim 1 , wherein the respective retaining element covers only one passage opening.
3. The lifting device as claimed in claim 2 , wherein the respective retaining element extends transversely to the longitudinal axis over less than a quarter of the outer side of the base plate in the corresponding corner region of the base plate.
4. The lifting device as claimed in claim 3 , wherein the retaining element is a flat planar component.
5. The lifting device as claimed in claim 4 , wherein the retaining element has a first region for covering a passage opening.
6. The lifting device as claimed in claim 5 , wherein the retaining element for fixing to the base plate.
7. The lifting device as claimed in claim 2 , wherein the retaining element is a flat planar component.
8. The lifting device as claimed in claim 2 , wherein the retaining element has a first region for covering a passage opening.
9. The lifting device as claimed in claim 8 , wherein the retaining element has a second region for fixing to the base plate.
10. The lifting device as claimed in claim 2 , wherein the retaining element has a second region for fixing to the base plate.
11. The lifting device as claimed in claim 1 , wherein the respective retaining element extends transversely to the longitudinal axis over less than a quarter of the outer side of the base plate in the corresponding corner region of the base plate.
12. The lifting device as claimed in claim 11 , wherein the retaining element is a flat planar component.
13. The lifting device as claimed in claim 11 , wherein the retaining element has a first region for covering a passage opening.
14. The lifting device as claimed in claim 11 , wherein the retaining element has a second region for fixing to the base plate.
15. The lifting device as claimed in claim 1 , wherein the retaining element is a flat planar component.
16. The lifting device as claimed in claim 15 , wherein the retaining element has a first region for covering a passage opening.
17. The lifting device as claimed in claim 15 , wherein the retaining element has a second region for fixing to the base plate.
18. The lifting device as claimed in claim 1 , wherein the retaining element has a first region for covering a passage opening.
19. The lifting device as claimed in claim 18 , wherein the retaining element has a second region for fixing to the base plate.
20. The lifting device as claimed in claim 1 , wherein the retaining element has a second region for fixing to the base plate.
