Multi-column lifting platform for wheel alignment of e.g. heavy vehicle, has lifting elements individually moved independent from each other, so that leveling of rails takes place in transverse direction of lifting elements

摘要

The platform has running rails (1, 2) lifted and lowered by lifting elements (11-14, 21-24) in a synchronous manner. The running rails are supported by the lifting elements (11, 14) spaced at a distance from each other such that the lifting elements (12, 14) of the running rail relative to the other lifting elements (11, 13) are displaced in a transverse direction of the running rail. The lifting elements are individually moved independent from each other, so that a leveling of the rails takes place in the transverse direction of the lifting elements.
