Abstract: A load supporting structure primarily for supporting X-ray apparatus in the form of a free standing unit which can be packaged as a kit and assembled at an on-site location. The load supporting structure comprises a pair of spaced apart longitudinally extending first beams with a plurality of spaced apart transversely extending second beams connected to the longitudinally extending first beams. The longitudinally extending beams are supported by a plurality of upright columns. The X-ray apparatus is supported on the transversely extending beams and is shiftable therealong. The distance between the transversely extending beams can be easily adjusted in order to compensate for the dimensions of the X-ray apparatus.
