ABSTRACT:
A lift apparatus comprising a wheeled base and a post mounted upright on the base. A fork lift having a guide frame which straddles the post and provided with rollers to travel on the post. The post is comprised of a plurality of interchangeable post segments releasably connected end to end. A winch mounted on one of the interchangeable post segments and a cable connected thereto and to the fork lift is operable to raise and lower the fork lift. This one post segment carries a bar to engage the guide frame to pivot the fork lift to a position parallel to this post segment to provide a compact arrangement and maintain the cable taut when the lift is disassembled. The winch includes a narrow groove cable pulley or spool so that connecting the winch device centrally of the post segment positions the rotational plane of the pulley in the center of the post with the result that no side resultant forces will be produced by the cable and no bracing required. The wheeled base is provided with stair-climbing tracks, and centrally therebetween lugs are provided to support an outrigger leg to vertically stabilize the lift. An extension shelf for the fork lift is provided to augment the work surface of the lift and to increase the height reaching capabilities of the lift. The extension shelf may be removed completely from the fork lift or may remain as part of the fork lift and folded as a back support therefor.
