A
pallet racking 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.
In a
pallet racking which comprises at least one pair of spaced, parallel rails, and first and second wheeled carts mounted in rolling relation with said pair of rails and defining a load-carrying area, said second cart being capable of rolling over said first cart to overlie said first cart without movement-obstructing cantact therewith, the improvement comprising, in combination:
each rail of said pair comprising a vertical web and a pair of generally horizontal flange portions having upper surfaces extending outwardly in opposed directions from said web, the wheels of said carts riding on said flange portions, the wheels of one of said carts riding on flange portions of each rail which are opposed to the flange portions on which the wheels of the other of said carts ride, at least a portion of said web extending above said flange portions to limit lateral movement of said wheels.
. The
pallet racking of the claim in which the wheels of said first and second carts are carried by brackets at an angle to permit said wheels to be generally perpendicular to said surfaces of the flange portions.
