systems, methods of loading and unloading the cargo-carrying systems, and systems for loading and unloading the cargo-carrying systems, with examples of the cargo-carrying systems being useful as removable cargo carriers that can be loaded into and carried for transport in a top-loading cargo transport vessel. ## Claims ### Claim 1 A method of loading cargo to a bottom-loading trailer, the trailer comprising: a front end supported by front wheels, an aft end supported by aft wheels, and a cargo-carrying system comprising a frame comprising a frame bottom and a bottom opening in the frame bottom, and a removable deck adapted to be supported by the frame; the method comprising: moving the trailer over a transport deck to position the frame above a loading platform space that includes a loading platform, supporting the removable deck on the loading platform positioned in the loading platform space, with cargo supported by the removable deck, elevating the loading platform, the removable deck, and the cargo, through the bottom opening, and supporting the removable deck on the frame. ### Claim 2 (depends on 1) The method of claim 1, comprising: supporting the removable deck on the frame at a deck-holding height using a deck holder engaged with the removable deck and with the frame, and removing the support of the removable deck provided by the loading platform. ### Claim 3 (depends on 2) The method of claim 2 comprising, with the deck holder engaged with the frame, and with the loading platform supporting the removable deck above the deck holder, lowering the loading platform to lower the removable deck onto the deck holder. ### Claim 4 (depends on 2) The method of claim 2, the system comprising a second removable deck adapted to be supported by the frame by a second deck holder that is adapted to engage the second removable deck and the frame to support the second removable deck, the method comprising, with the removable deck supported at the deck-holding height: supporting the second removable deck on the loading platform with cargo supported by the second removable deck, elevating the loading platform, the second removable deck and cargo supported on the second removable deck through the bottom opening, supporting the second removable deck on the frame at a second deck-holding height using the second deck holder engaged with the second removable deck and with the frame, and removing the support for the second removable deck provided by the loading platform. ### Claim 5 (depends on 1) The method of claim 1, comprising lowering the loading platform into the loading platform space. ### Claim 6 (depends on 1) The method of claim 1, wherein the removable deck comprises a side edge, the side edge comprises a notch, the frame comprises a deck holder attached to the frame, and the method comprises aligning the notch with the deck holder while elevating the loading platform and the removable deck with the deck holder passing through the notch. ### Claim 7 (depends on 1) The method of claim 1, wherein the removable deck comprises two side edges, each side edge comprises multiple notches, the frame comprises multiple deck holders, and the method comprises elevating the removable deck with the deck holders passing through the notches. ### Claim 8 (depends on 1) The method of claim 1, wherein the removable deck comprises two side edges, each side edge comprises multiple notches, the frame comprises multiple deck holders aligned vertically, and the method comprises elevating the removable deck with the deck holders passing through the notches. ### Claim 9 (depends on 7) The method of claim 7, comprising moving the removable deck vertically to a height above the deck holders, moving the removable deck horizontally above the deck holders, and lowering the removable deck to cause the side edges to be supported by the deck holders. ### Claim 10 (depends on 1) The method of claim 1, comprising transporting the trailer, removable deck, and cargo to a destination, removing the removable deck with the cargo supported on the removable deck from the trailer, and replacing the removable deck on the frame with a second removable deck. ### Claim 11 (depends on 1) The method of claim 1, wherein the loading platform space is located at an origin, the method comprising: transporting the trailer with the removable deck and the cargo from the origin to a destination, and at the destination, removing the removable deck with the cargo supported on the removable deck from the trailer through the bottom opening. ### Claim 12 (depends on 11) The method of claim 11, comprising, at the destination: moving the trailer over a transport deck to position the frame above a loading platform space that contains a loading platform, elevating the loading platform from the loading platform space, through the bottom opening, and supporting the removable deck within a frame space, and lowering the loading platform, the removable deck, and the cargo, through the bottom opening and into the loading platform space. ### Claim 13 (depends on 1) The method of claim 1, comprising transporting the trailer, removable deck, and cargo to a destination, removing the removable deck with the cargo supported on the removable deck from the trailer, and loading the removable deck with the cargo supported on the removable deck into a cargo transport vessel. ### Claim 14 (depends on 13) The method of claim 13, wherein the cargo transport vessel is a second bottom-loading trailer. ### Claim 15 (depends on 13) The method of claim 13, wherein the cargo transport vessel is a railcar. ### Claim 16 (depends on 13) The method of claim 13, wherein the cargo transport vessel is a bottom-loading railcar.
