ABSTRACT:
A transport cart is disclosed having a load receiving and supporting platform of sandwich-type construction formed from a pair of spaced panels each having offset portions which contact the other panel. The panels, where they contact each other, are rigidly secured together to form a rigid, load supporting sandwich. The platform is mounted on swivel casters interconnected by a linkage system which responds to the pivotal movement of the tow bar and which effects opposite pivotal movement of the front and rear casters to cause the cart to track the towing vehicle.
