A lifting cushion apparatus is equipped with five inflatable compartments. Each of the compartments extends the full length of the cushion and is connected to adjacent compartments by air ways. Several cushions may be connected to a common source of compressed air. The cushions may be stacked with the compartments interconnected in the vertical direction by apertures. In use, a load supported on the lifting cushion apparatus remains substantially stable as the device is inflated to elevate the load. |
