These containers are specially used for the movement of machinery or equipment. These are specialized shipping containers with collapsible walls, designed primarily for cargo that is too wide or too high to fit in standard containers. They come in standard lengths of 20 feet and 40 feet. The key feature is their collapsible end walls, which can be folded down to accommodate oversized cargo or machinery, then raised and secured for transport. Platform containers lack the side and end walls entirely, essentially providing a flat platform on which to secure cargo. Like the flat racks, they are available in 20 ft. and 40 ft. lengths. Their open design makes them ideal for extremely heavy or bulky items that wouldn’t be suitable for other types of containers.
