摘要：An adjustable load support for lifting, lowering, and transferring heavy loads isprovided, comprising a hollow container having a bottom, side walls, and a liftable top. Aportion of the top protrudes into the interior of the container. An elastomeric masssubstantially fills the remainder of the interior of the container. Sealing elements are alsoprovided which seal the portion of the top of the container extending into the interior ofthe container with the side walls. A substantially flat diaphragm is located between theelastomeric mass and the bottom of the container. The diaphragm is substantiallyparallel to the plane of the bottom of the container but is not in contact with the sidewalls of the container. Means for introducing a pressurized medium between thediaphragm and the elastomeric mass through an opening in the diaphragm is alsoprovided. When the pressurized medium is introduced into the container between thediaphragm and the elastomeric mass, the top of the container is lifted. Conversely, whenthe pressurized medium is let out of the container, the top of the container is lowered.
