Abstract: In a releasable locking device, which is useful at a beam-to-column connection in a storage rack, a housing having a lateral wall with two parallel slots has an end wall at an outer end and is open at the inner end, a locking pin having an internal portion movable within and along the lateral wall is movable between a retracted position and an extended position, toward which the locking pin is biased, and an outer sleeve is movable outside and along the lateral wall of the housing and is connected to the locking pin via a connecting pin extending through the locking pin, through the parallel slots, at each end to the outer sleeve. The outer sleeve has an external flange to facilitate pulling of the outer sleeve to move the locking pin toward the retracted position.

Abstract: In a storage rack comprising a front beam and a back beam, a roller track comprises two side rails and a series of rollers defining a tangent plane. A front hook, which is hooked over the front beam, defines a ledge projecting backwardly. A back hook, which is hooked over the back beam, defines a ledge projecting frontwardly. At each end, each side rail is supported on the ledge of the hook at that end. Each hook has a flange projecting upwardly from its ledge, between the side rails, so as to limit lateral movement of the roller track. Comparatively, the front hook is taller and the back hook is shorter, whereby the roller track can be easily inclined.

Abstract: In a storage rack, in which each of two columns has an outer wall facing outwardly and a side wall facing the side wall of the other column, a steel beam including two flange sections and an intermediate section extends between and is supported by the columns. Being fastened to an associated column, each flange section has a side plate adjacent to the side wall of the associated column and an outer flange adjacent to the outer wall of the associated column. Extending horizontally between the flange sections, the intermediate section is welded at each of its opposite ends to the side flange of an associated one of the flange sections. Being rolled from a steel sheet and defining a downwardly opening channel profile, the intermediate section has an outer wall, an inner wall joined unitarily to the outer wall so as to define an upper edge of the intermediate section, and a lower flange extending inwardly from a lower portion of the inner wall and having an upturned edge.
