Abstract
A warehouse storage rack organization capable of accommodating pallets arranged in four-deep push-back relation is described in which three carts that move along a single pair of rails permit internested disposition of the carts when they are unloaded, and the sequential movement of load-bearing carts by the imposition via a forklift of subsequent loads on the remaining carts. The organization utilizes only a single pair of rails to achieve the desired result, which rails are formed of conventional structural members whereby the cost of production of the organization is significantly reduced.
Claims11
A warehouse storage rack organization including a plurality of vertically spaced bays, each of said bays being adapted to receive up to four loads, said organization comprising:
- a single pair of parallel, oppositely spaced rails formed of two structural member, each member having an upwardly facing, generally horizontally extending upper support surface, and vertically spaced therefrom an upwardly facing generally horizontally extending lower support surface;
- a plurality of carts arranged for nested reception in said bay, said plurality of carts including a first cart having wheels movably supported on said lower support surfaces of said oppositely spaced rails, a second cart arranged, when nested, to overlie said first cart, said second cart having wheels movably supported on said upper support surfaces of said rails such that said wheels of said second cart are disposed to traverse the inner edge of said upper support surfaces, and a third cart arranged, when nested, to overlie said second cart, said third cart having wheels movably supported on said upper support surfaces of said rails such that said wheels of said third cart are disposed to traverse the outer edge of said upper support surfaces.
A warehouse storage rack organization according to claim 2 in which said rails are each formed of structural members having a vertical web and vertically spaced, substantially horizontally disposed flanges extending inwardly from said web.
A warehouse storage rack organization according to claim 4 in which said rails are each I-shaped in cross section.
