ABSTRACT:
A loader, transport and worktable cart having a base supported by front and rear wheels. An upright column supported by the base and in turn supporting a platform for up and down movement of the platform upon operation of a winch. A stop pivotally supported by the base to stop the front of the platform against downward movement past a predetermined level. A pivotal support for the rear of the platform allowing it to be lowered below the predetermined level so that when the rear of the cart is lifted the platform will be swung toward a generally level orientation. Spring retained cables for locking the platform against the stop. Glides behind the front wheels for aiding movement of the cart up or down steps. Handles extending upwardly and rearwardly from the rear of the base with hand grips positioned to be held by a repair-person standing generally erect when the rear of the cart is raised.
