ABSTRACT:
An apparatus for lifting and carrying heavy loads includes a generally horizontally extending support beam attached between a pair of generally vertically extending posts. The distance between the ends of the support beam is selectively adjustable. The bottom end of each support post is attached to a side beam and the side beams are connected together at a front end by a steering mechanism and at a rear end by a beam assembly. Both the steering mechanism and the beam asssembly are selectively adjustable to vary the distance between the side beams to correspond to the distance between the ends of the support beam thereby maintaining the posts in a generally parallel relationship. The side beams are also selectively adjustable to vary the length of the load carrying apparatus. Ground engaging wheels are rotatably attached to the side beams and the steering mechanism. A load carrying bar is connected by cable to a winch which is mounted on the support beam for releasably engaging and lifting a heavy load such as a roll of roofing material. The bar can be replaced by a load carrying pan attached at one edge to the cable and rotatably attached at an opposite edge to the side beams.
