ABSTRACT:
In the spaced between a plurality of airplanes that are supported by a rotatable bottom wall of an airplane hangar, lifting platforms are mounted on pivoting levers. The lifting platforms are adapted to support further airplanes on an elevated level. The lifting platforms can be lowered, thereby moving translationally in a radial outward direction. A single hydraulic cylinder arrangement is mounted in a sector containing a movable door section of the hangar peripheral wall. Each lifting platform, upon rotation into that sector, is automatically coupled to the cylinder arrangement for swinging the lifting platform downwards onto the level of the rotatable bottom wall. The lifting platform, after having been raised again, is automatically disengaged from the cylinder arrangement when it leaves that sector.
