Abstract
An attachment apparatus for releasably attaching a structure, such as a wheel assembly, to a standardized ISO container is disclosed. The ISO container includes standardized holes or openings situated in each corner of the container. The structure to be attached includes holes or openings that are substantially alignable with the ISO openings along the bottom edge of the container well. A locking lug is provided which is carried in the structure openings and releasably engageable with the ISO container openings. The locking lug comprises a shaft having an enlarged end portion which fits through the container openings. When inserted, the shaft is rotatable to a locking position. The locking lug is then tensioned to provide a secure and tight coupling between the structure and the container. The structure to be attached to the container is a wheel assembly having an interface assembly for interfacing with the container wall. The interface assembly includes foldable arms pivotable between an upright position, wherein the ends of the arms are coupled with the container, to a folded position, for transport.
