ABSTRACT:
A dolly with a U-shaped frame which is adjustable both in length and width, has a pair of wheels and a pair of brackets on the ends of the U-shaped frame. A heavy object to be moved includes two transverse members extending between opposite legs. At least one of the transverse members has retractable arms. The heavy object is first lifted at one end by the brackets beneath one transverse member then the retractable arms are extended and the other end of the heavy object is lifted onto the pair of wheels. A removable set of auxiliary wheels assists in transporting the object to a new location.
