Abstract:

A dolly includes a frame having a load deck for supporting a load and a plurality of axles coupled to the frame in a generally parallel relationship with wheels rotationally coupled to each side of the axles. Independent drive motors are operatively connected to each of the wheels such that the wheels can be driven completely independently from each other. This independent rotation enables the dolly to rotate in place about a vertical axis as well as minimize a turning radius of the dolly in a skid steer operation.
