Warehouse support structures capable of supporting heavy loads are supported by support members coupled to horizontal support beams, attached to vertical columns. The structure can comprise wire a mesh platform. The front end can be bent down, to nest against a horizontal support beam. The rear end can be bent up, over the horizontal to act as a pallet safety stop. It can also extend rearwards from the horizontal beam to provide additional support surface area. The construction presents a smooth, easy to assemble, snag free construction.

A manually assemblable/disassemblable rack mount for a load comprising: (a) a frame having first and second parallel spaced uprights arranged in a pair; each upright comprising a side projection having notches distributed along said side projection; (b) at least one crossbar member having first and second terminals; said at least one crossbar member releasably securable between said first and second parallel spaced uprights. The rack mount comprises terminal adapters connectable to said first and second terminals. The rack mount comprises anchoring plug members insertable into said notches. Each terminal adapter has a claw insertable into a bore within said anchoring plug members. At least one crossbar with said terminal adapters connected to said first and second terminals of said at least one crossbar is releasably mountable in a bridge position between said first and second parallel spaced uprights

Structural Column and Modular Structure for Electrical Cabinets Comprising said Structural column, includes a structural column (1) which, from a single piece, accurately determines two corners or vertexes of a modular structure (19) for electric cabinets. The modular structure (19) has four vertically positioned structural columns (1) and at least eight horizontal beams (20) connected to each other by means of screws (21). This invention also introduces an innovative joint between the elements of the structural columns (1), which are joined together by means of welds (6) and with the aid of limiters (12), positioning flaps (11) and engagers (9). Thus, this invention guarantees a perfect square of the modular structure and the correct assembly of the electrical cabinet, with no need for highly specialized labor. The modular structure (19) presented here can be manufactured entirely from low-cost metal materials such as carbon steel, significantly reducing the manufacturing costs of electrical cabinets.

An enclosure can have an enclosure body, the enclosure body can include an enclosure frame, and a first enclosure flange. The enclosure can have a center post having a first end and an opposite second end, the first end can include a first center post flange having a hole extending therethrough. The enclosure can include a gasket having a gasket hole therethrough, and a threaded fastener to threadingly engage the hole. The threaded fastener can be configured to rotate in a first direction while threadingly engaged with the hole, and the threaded fastener can contact the first enclosure flange to increase a distance between the first enclosure flange and the first center post flange in order to receive the gasket.

A collapsible rack assembly includes a vertical support, a first elongated shelf having a first corner region and a rail extending therefrom, and a second elongated shelf including a second corner region having a notch apparatus. The vertical support is structured to extend between and support the first and second elongated shelves when the collapsible rack assembly is in an ASSEMBLED position. The notch apparatus is configured to receive the rail in order to allow the first elongated shelf to nest within the second elongated shelf when the collapsible rack assembly is in a COLLAPSED position.

A shelf support beam (130) for use in a shelving unit (10) to support a shelf (22). A structural member (132) has a C-shaped cross-section. A web (144) separates a top flange (146) from a bottom flange (162). The top flange (146) is configured to support the shelf (22). The web (144), the top flange (146), and the bottom flange (162) define a channel (142). The channel (142) defines a cavity height (D1). The top flange (146) and the bottom flange (162) define a top flange width (D2) and a bottom flange width (D3), respectively. A ratio of the cavity height (D1) to a sum of the top flange width (D2) and the bottom flange width (D3) is greater than 1.707 or greater than 1.8. The cross-section has a moment of inertia of greater than 0.0613 or at least 0.0617. The web (144) includes a recessed region (164) in which the structural member (132) is offset in a direction into the channel (142). A centroid (148) of the cross-section is within 0.125 inch of the recessed region (164).

Beams and posts are disclosed. The beams and posts may be used for racks or shelving. The beams and posts may be formed by folding a sheet of metal. For example, the beams and posts may be non-volumous or hollow. Optionally, a portion of the wall of the beam or post is thickened, for example, by folding over the metal back and forth. Optionally, the thickened portion runs the length of the beam or post. In some embodiments, a fastener (e.g., a loop and/or hook) is formed in the thickened portion of the wall. For example, the fastener formed by punching out of the wall. Optionally, the fasteners are used to connect the posts to the beams.

An alignment tool and method that is easy to use during the installation of a base of a commercial storage rack over bolts extending up from a warehouse floor. The alignment tool comprises a cylindrical body having a first conically shaped upper end and a second lower end having a bolt receiving hollow opening therein. The opening extends up into said cylindrical body along a longitudinal axis of the body. The method includes placing the opening down over the bolts, with the conical top facing up, to protect the bolts and align the base as it is lowered over the bolts. The alignment tool can be easily removed, prior to bolting the base to the floor, such as with a removal tool through a hole in the alignment tool.

An apparatus is disclosed that provides a storage system designed to allow pickers to easily and efficiently pull products from all portions of the storage system from a single side of the storage system. The storage system includes a first storage rack that has a first plurality of columns and a first platform extending from one of the first plurality of columns. An outer edge of the first platform forms an end of the first storage rack. Positioned adjacent to the first storage rack is a second storage rack with a second plurality of columns and a second platform that extends from one of the second plurality of columns, where an outer edge of the second platform forms an end of the second storage rack. An aisle is formed by a predetermined distance between the outer edges of the first and second platforms.
