An attachment for a hand truck having a frame including at least two vertical frame members having a length and at least one crossbar connected between the vertical frame members to facilitate lifting and transporting odd shaped articles, wherein the attachment comprises:
- a base support plate having opposing sides and a top and bottom edge;
- means for removably connecting said base support plate to a hand truck frame which allows for selective adjustment along the length of the hand truck frame members so as to engage at least one crossbar on the hand truck;
- an upper and lower pair of load supporting prongs, each having an upper and lower surface;
- and
- means for adjustably attaching said prongs rigidly to said base support plate such that said upper pair of prongs can support a load from both said upper and lower surfaces and such that said upper pair of prongs are vertically spaced from said lower pair of prongs to form a parallelogram;
- wherein the rigid attachment and the spacing between said upper and lower prongs allows them to cooperate in order to lift and support an article therebetween.
