ABSTRACT:
A hoist system hoists a flat screen television or a heavy object in a room for attachment to a wall mounted attachment fixture. The hoist system has a wheel-supported base, and a central pillar with a raising and lowering element. The central pillar has a counter weight projection arm with a plurality of notches for carrying a counterbalance weight. A projection arm extends from the movable element in the direction opposite to the counterbalance weight arm with a downward pointing extension that carries a plurality of adjustable L-shaped brackets. The hoist system is brought close to a television or heavy weight at ground level and the L-shaped brackets are inserted therebelow. Weight balance is checked and a counterweight is placed on an appropriate notch in the counterbalance weight arm. The flat screen television or heavy object is then lifted to the correct height for wall attachment. Even though the load produced by the flat screen television or heavy weight being carried overhangs, delivery thereof to a point closely proximate a wall of a room can be reliably and safely accomplished by a single person.
