Open Top Containers for Top-Loading Cargo
Open top containers feature a removable tarpaulin roof instead of a solid top, allowing oversized cargo to be loaded from above using cranes.
Overview
Open top containers are modified standard containers with a convertible top covered by a removable tarpaulin and bows. This design allows cargo to be loaded from above using cranes, making them ideal for heavy machinery, tall equipment, and items that cannot be loaded through standard container doors. The tarpaulin can be removed entirely for loading, then secured for weather protection during transit.

Loading & Handling Tips
Frequently Asked Questions
How much over-height is allowed in an open top?
Cargo can typically extend up to 50cm above the container sides without OOG charges. Greater heights are possible but incur surcharges and may affect vessel stowage options.
Is an open top container weatherproof?
When properly secured, the tarpaulin provides good weather protection, but it's not as watertight as a standard container. For moisture-sensitive cargo, additional waterproof wrapping is recommended.
Can I use an open top for normal cargo?
Yes, open tops can be used for standard cargo when regular containers are unavailable. However, the lower payload capacity and higher cost usually make this uneconomical.
