The arrangement is assembled from a series of several, preferably directly contacting, platforms whose height is independently adjustable by device of a mobile lift arrangement, and can be held in different altitudes through a support arrangement, independently of the mobile lift arrangement. The support arrangements are arranged underneath a platform, and are formed columnar or scissors-like, whereby the support arrangements are movable in a released condition, and are automatically fixed in a stationary position under the load of a platform, or through a prior locking or clamping.
