ABSTRACT:
Apparatus for lifting objects into preformed openings in buildings. These openings can be recessed. The apparatus has a frame which has a head section and a tail section. The head section and tail section are rotably mounted to each other. A backstand is provided which is attached to the head section for preventing the objects to be lifted from moving as the objects are transported. Supports or forks are also provided which protrude from the head section and are used to support the objects to the transported. The apparatus has a leveling system which includes movable counterweights attached to chains. The movable counterweights balance the effect of the objects that the apparatus supports, keeping it level in the horizontal direction. The backstand can be folded down into the head section and the tail section folded onto the head section. Prior to or after use, as the apparatus is a lightweight, compact system, it can be transported in a pickup truck.
