ABSTRACT:
A workpiece support structure has a lower planar surface disposed above and parallel to an upper planar surface of a base assembly which is adapted to be supported on the forks of a fork lift truck for transporting the carrier and the workpiece. A plurality of air pockets are formed in one of the planar surfaces for receiving pressurized air from a suitable source so that the support structure floats on a cushion of air between the planar surfaces permitting substantially frictionless movement of the support structure relative to the base assembly for precision positioning of the support structure and thus the workpiece relative to the base assembly.
