Abstract:
A gravity descending and motorized ascending load carrying platform provides easy loading and installation underneath a ceiling. All mechanical and electrical components needed for operation of the platform travel with the platform. The mechanical components enable the platform to descend/ascend parallel to the floor, to hover parallel and over the floor when the platform supporting legs remain stored within its structure, to tilt when the cables on one side of the platform are under zero gravity force while the cables on the other side are still subjected to gravity force, to hover in a tilted position over the floor if the short supporting legs are not in contact with the floor while its long supporting legs are, to rest on its supporting legs whether in a position parallel to the floor or in a position forming a slope with the floor.
