ABSTRACT:
A pedestal supported hydraulic jack arrangement, and a kit for adapting a commercially available hydraulic bottle jack to use at selectively adjustable relatively elevated locations includes a first elongated hollow tubular member having a floor engaging based fixed on one end thereof and at least one transverse aperture extending therethrough near the other end thereof. A second elongated tubular member having a first set of generally parallel generally equally spaced transverse apertures and a second set of generally parallel generally equally spaced transverse apertures generally orthogonal to the first set. The second elongated member has a transverse dimension sufficiently small that it may be telescopically slidingly positioned inside the first hollow tubular member. There is a jack adapter plate fixed to one end of the second elongated tubular member, and a plurality of bolts for fastening a hydraulic jack to the jack adapter plate. A pin adapted to extend simultaneously through one transverse aperture of each tubular member to fix the relative locations of the first and second elongated tubular members. There is an optional saddle for adapting an object engaging end of a movable ram portion of a hydraulic jack to support a convexly curved heavy object. The saddle has an upwardly opening convex rest and a downwardly opening hollow cylindrical adapter for passing over and laterally securing the saddle to the object engaging end of the ram.
