subject: Pallet Racking Device Makes Storage Easily [print this page] In this invention, a pallet racking is provided which comprises at least one pair of spaced, parallel rails, and first and second wheeled carts, mounted in rolling relation with a pair of rails. The carts each define a load-carrying area and frontand rear wheels, with the second cart being capable of rolling over the first cart to overlie the first cart.
In accordance with this pallet racking, the wheels of the first and second carts respectively roll on the same rail surfaces. This of course means that the wheels of different carts are in a position to collide with each other to limit the cartmotion. However, in this invention, the front wheels of the second cart are positioned between the front and rear wheels of the first cart. The result of this is that the second cart can roll between a first, overlying position relative to the firstcart and a second position where most of the second cart can be spaced along the rails from the first cart before the front wheels of the second cart and the rear wheels of the first cart collide to limit relative motion between the carts.
As an additional embodiment, instead of the added, wheeled cart as described above, a second pair of the first and second wheeled carts in their relationship as described above may be mounted in their rolling relation on the other of the flangedportions, to provide four interrelating, rolling carts on the single pair of rails. All of the carts of the pairs are preferably proportioned to permit rolling into vertically overlying relation with the other carts of the pairs. This is preferablyaccomplished when the rails are of I-shaped cross section so that a plurality of separate rolling rail surfaces is provided.
Accordingly, by this invention, a pallet racking is provided in which up to four rolling, moving surfaces may be available for the storage of pallets, with a fifth front area being available when the pallets have been pushed rearwardly for addedpallet storage on the front sections of the rails themselves. By this means, the pallet racks may be constructed in a warehouse or the like in which the maximum warehouse storage density is provided with fewer access aisles than normal being required,to maximize the efficiency and capacity of the available storage space.
