Abstract:

A transportation dolly can have a frame, two axles pivotally coupled with the frame, each axle having two distal ends and a wheel assembly coupled at each distal end and a synchronous steering system. The synchronous steering system can include an intermediate link pivotally coupled with the frame, the intermediate link having a two distal ends, and a first push-pull rod coupling one of the two axles with the intermediate link, and a second push-pull rod coupling the other of the two axles with the intermediate link. The first push-pull rod is coupled to one distal end of the intermediate link and the second push-pull rod is coupled to the opposing distal end of the intermediate link. The first push-pull rod, the second push-pull rod, and the intermediate link provide counter phase synchronous pivoting of the two axles relative to the transportation dolly.
