An asymmetric mold core and method for use for forming curved floor openings in pallets is taught. The mold core contains: a base, the base attachable to a frame in a rotomold, a bottom section integral at a distal end to the base and a top section integral at a distal end to the base. Both the top section and the bottom section have convex radial curve shape, but the top section curve and the bottom section curve are positioned by having different centers of rotation so when the core is actuated it is only actuated around the center of rotation about the bottom curve which causes the top cure to drop away from the upper molded surface.

The present invention provides a thinner, movable load bearing structure having indentations, grooves, valleys, channels or other similar depressions on its underside. These depressions are mated with corresponding features for improved loading bearing capabilities. The load bearing structures also includes roughened side edges for improving the strength of the edges. The load bearing structure may be a dunnage platform or a container for storing and/or shipping cargo.

A pallet has a deck, a skid and a plurality of blocks, spacing the skid from the deck. The blocks comprise spacer portions and sleeve portions, wherein the sleeve portions may extend above and below the spacer portions. The deck and skid peripheral edges are cut away such that the deck and skid can be recessed with the blocks. The pallet constructed in this way can advantageously be made in any conventional size to meet the relevant norm or standard, while benefitting from the fact that the sleeve portions protect the edges of the deck and/or skid from impact. Furthermore, any impact imparted on the blocks is transmitted by the respective sleeve to the deck and/or skid. The elements of the pallet are connected without mechanical fasteners and the pallet can be easily repaired by removal and replacement of individual elements. A logistic system is also described.

A pallet structure includes a positioning mechanism is provided. The positioning mechanism includes an engaging element disposed on a sloping edge and adapted to be engaged with slits formed on the inclined surface of a vehicle. A coil spring is connected between the engaging element and the sloping edge and biasing the engaging element to protrude outward from an outer surface of the sloping edge. A retaining element is disposed between an inner surface of the sloping edge and a bottom deck board of the pallet and configured to retain the engaging element to move between an engaging position and a disengaging position. The protruding end of the engaging element is protruded outward from the outer surface of the sloping edge in the engaging position, and the protruding end of the engaging element is not protruded from the outer surface of the sloping edge in the disengaging position.

A method of assembling a pallet using a machine includes folding a first portion of a pallet support column to define a vertical support structure. The method further includes folding a second portion of the pallet support column to engage the vertical support structure. The method further includes gluing at least a portion of the second portion to the first portion. The method further includes coupling the pallet support column to at least one of a bottom member or a top member of the pallet.

A cargo pallet is disclosed. The cargo pallet may have a pallet base. The cargo pallet may also have a pallet liner. The pallet liner may have a pallet liner base. The pallet liner base may be positioned on the pallet base. The pallet liner may also have a pallet extension, which may be fixedly attached to the pallet liner base. The pallet extension may project outwardly from the pallet liner base. The pallet extension may also have a support surface that may at least in part extend outwardly beyond a footprint of the pallet base.

A pallet includes a top deck having a rectangular shape, a bottom deck having a rectangular shape, and spaced apart corner support blocks and spaced apart intermediate support blocks coupled between the top and bottom decks and forming a gap therebetween for receiving a lifting member. Centerline markings are carried by at least one of the top deck, the bottom deck, and the corner and intermediate support blocks so as to provide a visual aid to an operator of the lifting member.

A panel structure comprised of a plurality of extruded aluminum panel members. The aluminum panel members are joined together into a single structure by a friction stir welding process and at least one of the extruded aluminum panel members includes an extruded slot running along an entire length of the at least one of the extruded aluminum panel members. The extruded slots are used to attach hooks or other suitable retaining devices for securing objects to the panel structure or to directly attach structural elements or modules to the panel structure.

A plastic pallet comprising a deck for storing objects to be transported, feet which are formed protruding from a deck underside, and runners which are formed in each case connecting at least two feet to each other on their undersides. The plastic pallet also comprises at least one stiffening structure which comprises lower side rails arranged in the runners, and upper side rails arranged spaced apart therefrom, which are arranged above the lower side rails running parallel thereto. The stiffening structure comprises rungs, each with a predominantly closed surface, which connect the lower side rails in the feet to the upper side rails. The rungs are formed in one piece on the side rails or are connected thereto in each case via contact surfaces in bonded, friction-locking or form-locking manner. As such, the pallet bending stiffness and shear strength in a plane parallel to the deck upper side are increased.

Various embodiments of the present disclosure provide a bin riser positionable between different types of shipping bins to enable these shipping bins to stably stack atop one another in a way that inhibits an adjacent stack of shipping bins from toppling over during transit.
