Abstract
A storage rack entry vehicle for transporting loads of substantial weight in a warehousing system includes a plurality of wheels spaced from each other in the direction of both the length and the width of the vehicle and which support the vehicle for movement upon rails. The vehicle also includes an elevatable platform which supports the loads on the vehicle and distributes the load weight to locations adjacent each of the wheels. A rigid plate connects both the wheels and the load supports. However, this rigid plate is sufficiently flexible such that the plate flexes to maintain all of the wheels in continuous contact with the rails where one of the rails may vary in elevation such that at least one of the wheels might otherwise move out of contact with the rail surface.
