Abstract:
1. A cantilever cart storage system for moving a load, such as a pallet, from a storage position to an access position, comprising: at least one pair of spaced, parallel rails that are stationary and gradually slope downward from the storage position to the access position, the stationary rails having a lower rolling surface, a side rolling surface and an upper rolling surface; a cart having two pairs of wheels on each side of said cart, a rear pair mounted on a rear portion of said cart and a front pair mounted forward of said rear wheels and rearward of the center length of said cart, said wheels capable of rolling engagement with the upper and lower rolling surfaces of said stationary rail so that said cart remains on said stationary rails as said cart moves between the storage and access positions; wherein said rear wheels arc in contact with said upper rolling surface of said stationary rail at least when said cart is in the access position; and at least one guide roller mounted to a forward portion of the stationary rails in a horizontal orientation to contact at least one side of said cart to aide in lateral alignment of said cart during movement of said cart.
