Abstract: A manually-operated portable lift which may telescopically raise its mast or post so as to raise a lifting platform above the lift's initial height. The lift may be folded up to a compact and easily-moved configuration for ease of transport and storage. The lift includes a base with built-in outriggers which can be easily snapped out to fixed extended positions and returned to their storage positions. The outrigger is automatically latched in either such position but not between them. The base portion forward of the post can be manually unlatched and folded up parallel to the post. The platform and its arms have provision for manually mounting the arms of the platform in a low lifting position, a high lifting position, and a compact storage position wherein the arms are adjacent the platform. An extension mast is provided in either a storage position adjacent the main mast or as an extension of that mast.

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.
