A multiple vehicle position cantilevered lift comprising a stiff support for a cantilevered lift, said support being sized so as to be resistant to twist and torque loads, said support having a base plate with openings for selective alignment with openings provided in a concrete floor or footing, the openings in said floor having disposed therein an anchoring member comprising a compressible sleeve having a predetermined diameter and a threaded piston, having a predetermined diameter slightly larger than the cylinder and being contained in said sleeve and having a threaded internal or interior wall for receiving an anchor bolt and having a substantially tapered outer wall wherein as the bolt is fastened to a predetermined torque, the piston rises in the sleeve and expands the sleeve compressing the sleeve outwardly against the concrete surrounding the opening to anchor the sleeve and the bolt in the base plate, said support including framework to movably engage and support at least one cantilevered vehicle lift moveable between a first lowered position and a second raised position respectively for at least one vehicle, said lift having a drive provided for each cantilevered lift position, wherein a vehicle may be lifted at each lift position without interfering with the adjacent lift position.

The present pump design with the elimination of a separate hydraulic fluid path from the cylinder dramatically improves the efficiency and pressure achieved by the pump by 15% as a result of reducing the number of chambers provided in the pump interior. It is, however, imperative for reasons not completely understood that in order for these efficiencies to be obtained that a reservoir of oil be located adjacent the main oil intake volume to ensure quick filling of the main oil intake volume as the piston cycles to its pressure stroke. This prevents cavitation of the pump.
