ABSTRACT:
A pallet rack discloses a pair of spaced, parallel rails, plus first and second wheeled carts mounted in rolling relation with the pair of rails. The second cart is capable of rolling over the first cart to overlie the first cart without movement-obstructing contact therewith. In accordance with this invention, each rail of the pair comprises a vertical web and a pair of generally horizontal flange portions extending outwardly in opposed directions from the web. The wheels of the carts ride on the flange portions, with the wheels of one of the carts riding on the flange portion of each rail which is opposed to the flange portions on which the wheels of the other of said carts ride. At least a portion of the web stands above the flange portions to limit the lateral movement of the wheels.
