The present application discloses an assembled unit having a locking mechanism, comprising a pair of lateral guide rails, a pair of class I plate members, a spine member and at least one eccentric rotation member. Each of the lateral guide rails is configured with a sliding groove along a direction of extension thereof. Both ends of each of the class I plate members can be inserted into the sliding groove of the corresponding lateral guide rail. Both ends of each of the lateral guide rails are respectively configured with an engaging structure. The spine member is configured with a raised sliding block along its direction of extension. On a surface of each of the type I plate members, a class I engaging slot is configured in a direction parallel to the lateral guide rail, the class I engaging slot opening at a side of the class I plate member.

A pallet includes a base layer, a cargo layer and spaced apart supports coupled between the base and cargo layers and forming a gap therebetween for receiving a lifting member. The supports include outer corner supports each configured as a C-shaped bracket, and center supports each configured as a circular-shaped cylinder. Each center support including an outer wall having opposing ends, a center hub having opposing ends, and ribs extending between the center hub and the outer wall.

A transportable valve rack for securing a plurality of pressure safety or pressure relief valves in an upright position. The valves of the type having a bolted flange-type connection and the rack comprises a base assembly and a top plate mounted on the base assembly. The top plate includes a plurality of areas, with each area comprising a plurality of holes arranged on a circumference of two or more concentric circles. The plurality of holes extends through the top plate and at least four holes are on the circumference of each concentric circle. The holes are sized and arranged to align with bolt holes of pre-selected flanges of particular size and pressure rating. Nuts and bolts extended through aligned holes secure the valve to the valve rack.

A wheeled shipping/transport cart includes a cart frame that supports a plurality of wheels. The cart frame supports a plurality of stackable trays. The trays include a tray frame with opposed end members, a plurality of longitudinal support members disposed between the opposed end members, and a plurality of upright members nesting with upright members of an adjacent tray. A support structure is disposed between the opposed end members to form an arc corresponding to a curved surface of an article to be supported by the support structure. A pin is received through each of the upright members of the plurality of stackable trays to retain the stackable trays in a stacked configuration.

A collapsible crate includes a structural base and at least one collapsible corner post assembly coupled to the base. The corner post assembly includes supports configured to provide lateral protection to a payload in the crate. The corner post assembly is moveable between an upright position and a collapsed position. The crate can further be stackable and/or returnable.

A structural element (10) for forming a panel, with an upper plane (12) and lower plane (14) which are parallel and deformed along their plane at intervals by pods (16) which extrude toward the opposing plane with their internal faces mating to one another.

The present invention relates to a pallet having a stackable structure, which enables pallets having objects to be transported loaded thereon to be stacked or pallets alone to be stacked, and provides a pallet having a stackable structure comprising: a tray on which an object to be transported is loaded; a main frame on which one or more trays are mounted; at least one supporter, one end of which extends from the side of the main frame; and a plurality of pivot parts provided in the main frame, each of which is connected to a pivot rotation unit so that each supporter pivots from the main frame with respect to the pivot rotation unit provided at one end, each pivot part enabling a supporter to be selectively locked directed upward.

A plastic pallet and method of construction that permits plastic pallets of numerous different sizes and options to be easily produced from only a very small inventory of parts and without requiring a user to purchase or construct numerous different shapes and sizes of molds in order to produce a wide variety of pallets of various shapes, sizes and options.

A shipping container comprising a basket, a plurality of feet, and a plurality of removable corner columns. In some embodiments, the shipping container comprises a basket, a plurality of feet, and a plurality of foot pads. Further embodiments include foot pads with drill release locks.

A pallet protector unitarily formed as a molded plastic part reinforces a wooden pallet. Its faceplate is nailed or screwed to the front and optionally the back face and side faces of the pallet. The protector has entry openings for the tines of a forklift and the openings are articulated into hollow collars that extend into the pallets inner regions. These collars provide a structure that accepts the weight and moment between the tines and the pallet and spread it across of the entire front of the pallet. RFID modules can also be included.
