Abstract:
A portable hoist adapted for attachment to a hand truck nose plate is disclosed. The hoist comprises an adapter that sandwiches the nose plate and a hole or holes may be fabricated in the nose plate for securing hardware to be installed, such as a bolt, bolts, strap, etc. Receivers on the hoist hold removable, load supportive legs securely in place. Casters may be attached to legs to improve mobility. A jib assembly capable of several height settings remains reasonably level at all times when in use, making it ideal for tight spaces. The pivot point of the arm is at the end of the mast opposite the adapter assembly, the other end attaching to the handle of the hand truck and securing with a latch. A winch attached to the arm provides a cable extending to and about a sheave or sheaves, terminating beyond the sheave carried at the free end of the jib boom. A brace on the mast allows the arm latch to secure when the arm is collapsed. The jib assembly folds downward with a brake to hold the boom reasonably parallel to the mast. A cable securing hook is attached to the mast, and with slight tension on the cable, the latch brace and cable hook enable the hoist to be carried about easily, utilizing the boom as a handle.
