The present disclosure provides a customizable trolley to improve the Space Productivity Index (SPI) in Last Mile Large (LML) delivery hubs. The customizable trolley [100] comprises at least one base [102]. The customizable trolley [100] also comprises a set of connecting rods [106], wherein each connecting rod of the set of connecting rods [106] is coupled to at least one corner of the at least one base [102, and each connected rod comprises of a plurality of grooves. Further, the customizable trolley [100] comprises a set of clamps [110], wherein each clamp of the set of clamps [110] are detachably attached to at least one groove of the plurality of grooves. Furthermore, the customizable trolley [100] comprises a set of adjustable separators [108] detachably attached to the set of clamps [110].

According to an example aspect of the present disclosure, there is provided a novel caster assembly for a roll container (1000). The caster assembly has a caster (410) with a fork (411) as well as a pin (414). The pin (414) may be repeatedly attached to and removed from the fork (411) so as to attach the chassis (100) of the roll container (1000) to the fork (411). The pin (414) also acts as the hinge pin of a pivotable side wall (200) of said roll container (1000).

The invention is a wheeled folding tray cart and method. The wheeled folding tray cart comprises a collapsible wheeled framework pivotally supporting a set of split shelves, each split shelf comprises a pair of half shelves. The wheeled folding tray cart moves between an open operating position wherein the set of split shelves are held in spaced-apart, stacked, horizontal orientation within the collapsible wheeled framework and a closed storage position wherein the collapsible wheeled framework is collapsed in manner to move each half shelf pair into an accordion-like, inverted “V”-shaped or accordion like configuration. An extension coiled spring attached to the collapsible wheeled framework assists in the movement of the wheeled folding tray cart between open operating position and the closed storage position. A sheath encloses at least a portion of the spring to provide resistance to the spring's movement to limit potential operator exposure to pinch injuries.

According to an example aspect of the present disclosure, there is provided a novel chassis (100) for a roll container (1000). The chassis (100) features a first arm (121), a second arm (122), and a crossmember (110) for connecting the first arm (121) to the second arm (122) so as to form the chassis (100). The crossmember (110) is formed to be less resistant to mechanical strain than that of the first and second arm (121, 122). The crossmember (110) is such that it can be repeatedly attached to and detached from the first and second arm (121, 122).

A folding wagon comprising a collapsible wagon basket, a folding wagon frame comprising folding ends and folding sides, wherein the folding ends and the folding sides connect at four corners, each corner comprising a vertical frame element, wherein the vertical frame elements are extendable to enable the folding the wagon to transform from an extended configuration to a collapsed configuration, a folding base formed by a plurality of base support elements that are hingedly attached to the vertical frame elements and hingedly attached to a central base element, wherein the hinged attachments of the base support elements to the vertical frame elements are multi-directional hinges allowing multiple degrees of freedom in the movement of the base support elements when the folding wagon is transformed from the extended configuration to the collapsed configuration, a handle attached to the first folding end, and a plurality of wheels.

The present invention provides a folding trolley, which includes a bottom frame folding and unfolding assembly, a front wheel assembly and a rear wheel assembly. Side frame folding and unfolding assemblies are provided on both sides of the bottom frame folding and unfolding assembly, the bottom frame folding and unfolding assembly can be unfolded or folded through the side frame folding and unfolding assembly; one end of the side frame folding and unfolding assembly is connected with the front wheel assembly, the middle part of the side frame folding and unfolding assembly is connected with the bottom frame folding and unfolding assembly, and the other end of the side frame folding and unfolding assembly is connected with the rear wheel assembly. The invention provides a folding trolley, which overcomes the defects of an existing trolley with low load bearing capacity and poor functionality.

Collapsible reusable watertight carrying cases are provided in sizes varying from small containers without wheels to large sealable container bins on wheels, to provide large quantities of water or other supplies and cargo. The cases are assembled or in disassembled from a joined flat space-saving configuration to a functioning case and vice-versa. The sides of the cases are erected progressively by hand by interlocking self sealing reciprocating channel and channel engaging members elements at the corners. The panels also disassemble progressively by being manually pulled apart. When folded into a flat storage or shipping configuration, the panels stay together, resisting unfolding by virtue of snaps which are either molded into the panels or bonded to them. The carrying cases are resistant to water, dirt, bacteria, molds, allergens, and inclement weather.
