Abstract: A flatbed deck with corner castings connects to the intermodal equipment trailer chassis. Twist locks are retractable in upper corner castings to provide an absolutely flat deck to facilitate loading and unloading. Lower corner castings are connected to corner twist locks of a trailer chassis. Cargo is loaded and a rigid three-dimensional lid is lowered onto the flatbed deck. The rigid lid has corner castings that cooperate with twist locks at corners of the new flatbed deck. Lid corner castings are recessed in the lid. The lid seals to the deck to prevent moisture ingress. Corner castings extend slightly downward from the corners of the lid. Two or more short individual lids are secured separately to the new decks. Partial loads are individually covered and protected by the short lids which are seated and sealed to the deck by securing lid corner castings.
