Standard ISO Open Top Container
The 20’ Open Top Container (ISO 22U1) is designed for cargo that cannot be loaded through standard container doors due to its height 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 22U1 identifies a standard 20-foot Open Top Container.
Its versatile design makes it suitable for transporting oversized, heavy and over-height cargo while remaining fully compatible with international intermodal transport by sea, rail and road.
