Abstract: A collapsible intermodal flat rack features a cargo deck with first and second arches pivotally mounted to the cargo deck. Each arch is provided with a crank mechanism including a gearbox having an input shaft and an output shaft. The output shaft is attached to the corresponding arch so that the arch may be moved between a storage position, where a top portion of the arch is located adjacent to the cargo deck, and a use position, where the top portion of the arch is elevated from the cargo deck, by actuation of the input shaft.
