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.

An apparatus for lifting and carrying loads comprising: a generally horizontally extending support beam including means for adjusting the distance between opposite ends of said support beam; a pair of generally vertically extending posts each attached at a lower end to one of a pair of generally horizontally extending side beams with said side beams having at least one ground engaging wheel; means for releasably attaching each said end of said support beam to a corresponding one of said posts including a sleeve attached to said support beam and slidably engaging one of said posts, and a releasable locking mechanism attached to said support beam and releasably engaging an aperture formed in said post; means for adjusting the distance between said posts to correspond to the distance between said ends of said support beam including a tubular steering beam, a pair of adjustment beams connected at their outer ends to said side beams and telescopically engaging at their inner ends opposite ends of said steering beams and means for releasably attaching said adjustment beams to said steering beam; a steering mechanism having at least one ground engaging wheel mounted on said steering beam for rotation about a generally vertical axis and a steering rod attached to said wheel; means for adjusting the length of said side beams; and means attached to said support beam for releasably engaging and lifting a load.
