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.
Claims15
A dolly comprising:
- a frame for supporting a load;
- the frame having a left side and a right side;
- a plurality of axles coupled to the frame so as to be generally parallel to one another;
- a wheel rotationally coupled to each of the plurality of axles;
- and
- drive motors operatively connected to each of the wheels, wherein the drive motors rotate the wheels independently from each other.
A method of steering a dolly having a frame with a left side and right side, a plurality of axles, and a wheel rotatably coupled to each of the plurality of axles, the method comprising:
- coupling a drive motor to each of the wheels;
- and
- actuating the drive motors to drive at least one of the wheels of the dolly independently from the other wheels.
