A composite pallet structure includes a unit pallet including: upper and lower basic supporting boards, at least two spaced-apart auxiliary rods attached to each of the corresponding sides of the upper and lower basic supporting boards, a plurality of spacers distributed between the auxiliary rods on the upper basic supporting board and the auxiliary rods on the lower basic supporting board, and a plurality of fixing elements for restricting the spacers within the space between the upper and lower basic supporting boards in order for the unit pallet to have high supporting strength. The composite pallet structure needs no soldering and, therefore, can be easily repaired and recycled.

A displacement arrangement for use in a combination dolly-pallet includes an impelling member movable between first and second positions. A linkage is pivotally connected to the impelling member. When the impelling member moves between the first and second positions, the linkage moves pivotally relative to the impelling member to an extended position.

A monolithic interlocking tile, manufacturing method, and covering are disclosed. A closed-cell foam material is injected into a mold to form a monolithic structure having a first surface, a second surface offset and opposite the first surface, the first surface including a first lip located at two adjacent sides of the structure with a plurality of shaped protrusions, and the second surface including a second lip located at two other adjacent sides of the structure and forming a plurality of shaped apertures matching in number and shape with the plurality of protrusions; and a recess formed in the second lip and forming a hole for receiving a fastener to secure the monolithic structure to a supporting structure. Multiple monolithic interlocking tiles are interlocked together to form the covering for a floor, wall, ceiling, or roof.

A cargo pallet having parallel, spaced runners with parallel, spaced slats mounted transverse thereto by removable pins. Each of the slats is substantially identical and each has different opposing faces so that when the slats are reversed the different faces provide different cargo-supporting surfaces. There are slat grooves on the runners into which the slats are mounted, along with endwalls, to prevent something from extending between the slats and the runners to separate slats and runners. Blockers extend laterally from one or both sides of the slats to prevent a forklift from contacting the cargo, and when the slats are reversed the blockers interlace.

A pallet includes a top including a product support surface and an opposing underside, with outer sides extending between the product support surface and the underside. Four feet each extend away from the underside of the top, and each foot has a first opening facing out through the product supporting surface of the top. The feet thus allow stacking of such pallets with the feet of a first such pallet extending into the first openings of a second such pallet. Product tab receiving areas are for receiving respective product tabs, with each product tab receiving area having a slot within the top adjacent a respective outer side of the top. The slot has a pair of spaced apart opposing long sidewalls and a pair of spaced apart opposing short sidewalls adjacent to the pair of long sidewalls, with one of the long sidewalls including a laterally extending tongue for engaging an opening in one of the product tabs.

A safety catch for preventing a drop-down side door from separating from the sidewall of a shipping container in the case of a hinge failure and a shipping including at least one safety catch.

A pallet for transporting products thereon includes a top having a product support surface and an opposing underside, and with outer sides extending between the product support surface and the opposing underside. Four feet each extend away from the underside of the top. Each foot has a first opening facing out through the product supporting surface so that the feet allow stacking of such pallets. At least one product tab receiving area is adjacent an edge of the top and has a parent slot within the top with a partially closed bottom forming a shelf and an opening adjacent the shelf. An inner slot extends through the opening adjacent the shelf so as to be recessed below the parent slot. The inner slot has a pair of spaced apart sidewalls, a closed bottom, and with one of the sidewalls having a projection extending towards the other sidewall.

A cargo pallet having parallel, spaced runners with parallel, spaced slats mounted transverse thereto by removable pins. Each of the slats is substantially identical and each has different opposing faces so that when the slats are reversed the different faces provide different cargo-supporting surfaces. There are slat grooves on the runners into which the slats are mounted, along with endwalls, to prevent something from extending between the slats and the runners to separate slats and runners. Blockers extend laterally from one or both sides of the slats to prevent a forklift from contacting the cargo, and when the slats are reversed the blockers interlace.

A two-component pallet includes an upper part defining a deck and including a plurality of posts, and a lower part including a corresponding plurality of feet arranged in complement with the posts. The posts and the feet each include an alignment member and ribs. The upper part is welded to the lower part such that the ribs are welded together. The alignment member of the posts is engaged with the alignment member of the feet without being welded. In some embodiments, the ribs are bent to better absorb impact from a forklift tine or the like.
