The 40’ High Cube Open Top Container (ISO 45U1) is designed for cargo that cannot be loaded through standard container doors due to its height, weight or loading method. Built in accordance with ISO and CSC requirements, it features a removable tarpaulin roof and detachable roof bows, allowing cargo to be loaded from above using cranes or other lifting equipment. The ISO code 45U1 identifies a 40-foot High Cube Open Top Container.
Its increased internal height provides additional loading volume, making it ideal for oversized, over-height and heavy cargo while remaining fully compatible with international intermodal transport by sea, rail and road.
