Abstract
A crate assembly includes a crate having a base and an interchangeable cartridge supported by the base. The interchangeable cartridge is insertable and removable from the base of the crate. The interchangeable cartridge includes a cartridge base and a well. The well is formed by a floater base, side rails, a back board, and a front board. Energy damping components are selected to support a desired load and are disposed between the cartridge base and the floater base thereby providing cushioning to a load carried in the crate. Brace brackets attach to ends of the side rails. After loading a server rack, openings on the front board slide over end bolts of the brace brackets thereby providing toolless securement of the load within the well. Worn cartridges are replaced with new cartridges thereby extending crate life and cartridges are customizable depending on application to support different load dimensions or weights.

DETAILED DESCRIPTION
(32) Reference will now be made in detail to some embodiments of the invention, examples of which are illustrated in the accompanying drawings.
(33)
(34)
(35) The crate assembly 10 is designed to support multiple shipments past the point when interchangeable cartridge 12 is replaced with a new interchangeable cartridge. The amount of shipments supported by the interchangeable cartridge 12 depends on the size and weight of the load, shipment distance, and other characteristics that affect wear of the interchangeable cartridge 12. In addition, a crate can be reused or repurposed by swapping out the interchangeable cartridge 12. For example, the interchangeable cartridge 12 configured for one type of load is swappable out for another interchangeable cartridge configured for another type of load having different weight, dimensions, or configurations.
(36) The crate 11 is configured to carry sensitive equipment, such as servers, storage devices, networking components, and other computing related devices. In one embodiment, the crate 11 is a server rack crate that carries only servers having storage and networking components and no other types of loads. In another embodiment, the crate 11 is a computing equipment crate that carries only computing equipment and no other type of loads. In one embodiment, the load is loaded directly onto the interchangeable cartridge 12 without any intermediate structure between the load and the interchangeable cartridge 12.
(37) The crate frame 11 comprises a base panel 13 that provides bottom support for the assembly. A left panel 14 and a right panel 15 form the side walls of the crate frame 11. In one embodiment, the left panel 14 and right panel 15 are made of wood, engineered wood, or plywood. In another embodiment, the left panel 14 and right panel 15 are made of reinforced plastic.
(38) A front panel 16 is included in the crate assembly 10, which can be opened for access to the interior. In one embodiment, the front panel 16 is hinged. In another embodiment, the front panel 16 is completely removable.
(39) A back panel 17 encloses the rear of the crate assembly 10. In one embodiment, the back panel 17 is fixed. In another embodiment, the back panel 17 is removable for rear access.
(40) A top panel 18 forms the upper surface of the crate assembly 10. In one embodiment, the top panel 18 is flat. In another embodiment, the top panel 18 is slightly curved for improved water runoff.
(41) The crate assembly 10 rests on support skids 19, which are attached to the base panel 13. In one embodiment, the support skids 19 are made of wood. In another embodiment, the support skids 19 are made of high-density plastic.

(96) In a first step (step 101), an interchangeable cartridge is placed on a base of a server rack crate.
(97) In a second step (step 102), a load is placed within the interchangeable cartridge.
(98) In a third step (step 103), the load is enclosed with a plurality of panels.
(99) In a fourth step (step 104), the plurality of panels is secured to the base of the server rack crate.
(100)
(101) In a first step (step 201), a crate assembly with a crate and an interchangeable cartridge along a base of the crate is provided to a transporting entity.
(102) In a second step (step 202), the transporting entity is instructed to place a load onto the cartridge and transport the crate assembly carrying the load.
(103) In a third step (step 203), a second interchangeable cartridge that is swappable with the first interchangeable cartridge after wear is provided to the transporting entity.
