subject: New System Of Palllet Racking [print this page] In accordance with this invention, a pallet racking system is provided with rolling carts for holding the pallets in which the wheels of the carts are not flanged, which results in a reduction in manufacturing expense, and also permits less critical control in the control of dimensions of the wheels and their placement. Additionally, in accordance with this invention, the rails upon which the wheeled carts roll may be protected to a significantly increased extent against falling debris from the pallets and the like, so that the problem of obstructions to the free rolling of the carts is significantly reduced. Additionally, the vertical space in a stack of pallet racks in accordance with this invention may be utilized in a particularly efficient manner, for improvements in storage density.
Accordingly, a pallet racking in accordance with this invention is provided in which the rolling characteristics of the cart on the rails is improved, with less possibility of the wheels jamming on debris that has been dropped and the like becasue of the protective features provided, and in which the carts exhibit a self-centering characteristic which reduces binding of the wheels against the central web of the rails, and also derailment, in a spontaneous, natural manner. Simple, common, non-flanged wheels may be used while obtaining reliable and effective functioning for the storage for multiple pallets.
Also, pallet racking retainer plates may be provided on the front of the rack of this invention to prevent the second pallet added to the rack, which is supposed to rest on the lower cart, from accidentally engaging the lower cart to drive it rearwardly and instead rest on the rails rather than the lower cart. This, of course, would prevent a third pallet from being placed on the rails, so that undesirable happening is prevented by the pallet retainer plates.
