Abstract
A load supporting structure is disclosed for supporting and maintaining a heavy load stable when being moved on a substantially flat supporting surface by another vehicle. The structure includes a rigid annular foot, and a pressure chamber with one of its walls being a portion of the flat surface. A rigid load supporting platform is connected to the rigid foot and to the pressure chamber for supporting a heavy load. Air is directed into the pressure chamber at sufficient pressure to support substantially all the weight of the supporting structure and the load, but with insufficient pressure to lift the rigid annular foot from the flat surface. The air in the chamber is substantially prevented from flowing under the annular foot but will allow some air to escape in the event crevices or the like in the substantially flat surface provide air flow paths.
