Abstract: A storage rack comprising a plurality of bays each having at least a front storage location and a rear storage location and which is adapted to receive at least two loads with the first-received load being movable between the locations. Each bay comprises an open front end through which the loads can be inserted and removed, a support surface for supporting a load at the front storage location, and first rails disposed above the support surface and extending between the storage locations. Each bay further comprises a trolley for carrying the first-received load. The trolley is supported by the rails and is movable on the rails between the locations so that both loads can be inserted into the bays at the front storage location.

Abstract: Storage racks include bays for accepting three loads of goods from an open front end wherein telescoping upper and lower trolleys move along a track assembly from the front of the bay rearward. The upper and lower trolleys are successively loaded, and they are moved rearward to rear and central locations as each following load is inserted, with a third load of goods being located on the track assembly in front of the two loaded trolleys. The track assembly is inclined downward toward the front of the bay, and catches are associated with the track assembly to prevent return movement of the loaded trolleys to the front of the bay until released.

Abstract: An adjustable storage rack utilizing end frames wherein front and rear columns are interconnected to provide fixed fore-and-aft spacing. The columns are apertured at spaced intervals to attach beams having mating connectors. The columns include apertured vertical members which are shortened to terminate substantially above the floor plus unapertured posts which extend to the floor and overlap with each other along a distance preferably at least equal to the shortened distance. The upper ends of the posts are closed while the bottom ends of apertured members are open.

Abstract: A storage rack for holding superposed loads of palletized goods for use with a stacker crane or the like. Parallel upright trusses are spaced apart to define storage bays therebetween, and compartments within the bays are provided by rails carried by the trusses. U-shaped members connected to the columns of the trusses constitute parallel rails extending, respectively, into adjacent storage bays. Rectangular tubes may be crush-bent to the desired U-shape and connected by welds and/or brackets or supports to the columns of the trusses.

Abstract: A guiderail system for floor-mounted storage racks which is located generally adjacent the access aisles. Tubular guiderails are supported by brackets which include a pair of sockets extending in opposite horizontal directions which sockets are proportioned to closely interfit within the tubular guiderail. A main plate portion of the bracket is disposed under the storage rack column or support to transfer the load carried by the storage rack to the bracket and thus stabilize and rigidify the guiderail system.
