ABSTRACT:
A load handling dolly (1) assists in the transportation of a load P, such as a piano. A pair of cross-pieces (11, 12) are selectively slid beneath the load, either directly or using an intermediate support plate (17). A pair of side frames (3, 4) are disposed on either side of the load above free ends of the cross-pieces. The cross-pieces are received within extremities or eyelets (13b) of tie rods (13a) which are supported by the side frames for vertical movement by rotating a nut (15). As the nuts are turned, the tie rods, cross-pieces, and the load are lifted, transferring the load to two sets of wheels (5, 6, 7; 8, 9, 10) that rotatably mounted in the side frames.
