The stand includes a rectangular base having a pair of parallel beams or rails. A pair of clamp fasteners are mounted to each end of the beams; and they may be adjusted longitudinally of the rails. Support wheels are mounted to each clamp fastener for vertical adjustment. At each end of the base, a pair of the clamp fasteners carries a vertical box frame between the rails. Each box frame telescopically receives and guides an adjustable vertical extension or slide which may be raised by a hydraulic ram. The clamps are mounted off vertical center on the box frames, so they may be reversed for further vertical adjustment. Other elements may be mounted to the base rails by the clamp fasteners.
