发明名称 Lifting and carrying heavy loads
摘要 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 lower end of each post is attached to one of a pair of generally horizontally extending side beams which are connected together at a front end by a steering mechanism. A winch for moving a load is coupled to the support beam and is connected to either a pan or directly to a load for releasably engaging and lifting a load. A rear edge of the pan is rotatably attached to the side beams and a front edge can be lifted by the winch to dump a load carried on the pan. A pair of lifting arms can be connected between the posts and the side beams to cooperate with the winch to move a load between the ground and a roof.
