Abstract

The lifting platform (10) has at least two lateral pillars (12, 14, 33). Each pillar has height-changeable, pivotable arms (13, 34, 44) that are displaceable telescopically in length. An end of each arm has a decoupling device with a receptacle (31, 41) for supporting an object. A carrying device (11, 50) has receiving points corresponding to the number of the receptacles (31, 41). The lifting platform and the carrying device are positioned with respect to each other without impairing an object resting on the at least one receptacle. The at least one receptacle (31, 41) is placed onto the at least one receiving point, and the carrying device (11, 50) together with the transferred at least one receptacle (31, 41) and an object thereon is removed from a region of the lifting platform (10).

First claim

What is claimed is:

1. A method for increasing utilization of a vehicle lifting platform by transferring a lifted vehicle from the lifting platform to a carrying device, the lifting platform having at least two laterally spaced apart pillars each of which has at least one height-changeable pivotable arm, each of the arms being telescopically displaceable in length and an end of each of the arms remote from the respective pillar having an opening, coupling and decoupling devices that include internally threaded sleeves temporarily arranged in the openings of the respective arms, externally threaded bolts threadedly engaged respectively with the internally threaded sleeves, bores extending into bottom ends of the bolts and supporting plates fixed to top ends of the bolts for supporting the vehicle, the method comprising:
displacing the arms so that the supporting plates align respectively with receiving points on an underbody of the vehicle;
raising the arms relative to the pillars so that the supporting plates approach the receiving points on the underbody of the vehicle;
rotating the bolts relative to the sleeves so that all of the supporting plates engage the receiving points on the underbody of the vehicle;
raising the arms farther along the pillars to lift the vehicle sufficiently to work on the underbody;
transferring the vehicle to the carrying device during a work interruption by:
positioning the carrying device under the vehicle;
individually adjusting receiving points of the carrying device to align with the bores in the bolts;
lowering the arms along the pillars so that the receiving points engage in the bores;
continuing lowering the arms so that the sleeves, the bolts and the supporting plates separate from the arms and remain on the receiving points;
moving the carrying device away from the lifting platform; and
positioning new coupling and decoupling devices on the arms so that a further vehicle can be worked on during the work interruption.

2. The method of claim 1 , in which the carrying device has first and second crossbars, at least the first crossbars being displaceable relative to the second crossbar, left and right arms mounted at opposite ends of each of the crossbars, each of the arms being pivotable and movable telescopically relative to the respective crossbar, and the receiving point located on said arm comprises a stud onto which the threaded sleeve of the receptacle is plugged, and the step of individually adjusting the receiving points of the carrying device to align with the bores in the bolts comprises individually pivoting the arms relative to the respective crossbar and individually telescopically moving the arms relative to the respective crossbar so that the receiving points of the carrying device align respectively with the bores in the bolts.

3. The method of claim 1 , wherein the carrying device is a vehicle skid.

4. The method of claim 1 , wherein the step of moving the carrying device away from the lifting platform region is carried out by operating a traction apparatus.
