Abstract: The push back storage rack system comprises a framework defining a storage bay for multiple pallets including a plurality of generally vertical uprights and a plurality of generally horizontal shelf beams. A pair of laterally spaced, generally parallel rails is supported by the framework and extends into the storage bay. Each of the rails defines inner and outer wheel tracks and is inclined in a direction towards the rear of the storage bay. A generally rectangular first cart has a pair of front wheels and a pair of rear wheels. The front and rear wheels roll along the inner wheel tracks. The generally rectangular second cart is positioned behind the first cart and has a pair of front wheels and a pair of rear wheels. The front wheels roll along the outer wheel tracks and the rear wheels roll along the inner wheel tracks. A generally rectangular third cart is positioned behind the second cart and has a pair of front wheels and a pair of rear wheels. The front and rear wheels roll long the outer wheel tracks.

Abstract: A storage rack includes an upright frame structure having a plurality of upright axial load carrying members at its corners. A plurality of pairs of laterally spaced, generally parallel support beams extend across pairs of the upright axial members at different elevations to support pallets and the like. Brackets interconnect the support beams and the upright axial members. Each bracket includes at least one axially adjustable lug which is accommodated by a primary hole in one of the upright axial members. The primary holes are shaped so that the lugs self-plumb when accommodated by the holes. The lugs are axially adjustable to allow for a flush connection between the brackets and the upright axial members. The lugs can also be removed from the brackets allowing the brackets to be used in structural storage racks and roll-form storage racks. The lugs can also be positioned on the bracket to allow the bracket to be attached either to a structural storage rack or a roll-form storage rack.

Abstract: A storage rack to support pallets and the like includes an upright frame structure having at least one pair of generally parallel, laterally spaced support beams across which a pallet or the like is to be supported. At least one transverse support member spans the support beams. Retainers act between the support beams and opposed ends of the support member and are in the form of complimentary formations on the support beams and the support member.
