40ft Flat Rack Container

The project-cargo platform — up to ~39 t payload on 12 metres

The 40ft flat rack is the standard platform for project cargo: a 12-metre reinforced bed rated far above normal boxes (typical max gross 45 t). With no roof or side walls, over-width and over-height pieces ride on it routinely — construction machinery, boats, plant modules — planned as out-of-gauge cargo.

Typical cargo & use cases

  • Construction and mining machinery: excavators, loaders
  • Industrial plant modules, tanks and pressure vessels
  • Yachts and oversized vehicles

Loading tips

  • The bed height (~0.65 m) counts against road height limits — verify the full transport chain, not just the sea leg.
  • Welding lashing points to the cargo frame is common — coordinate with a marine surveyor.
  • Get OOG dimensions surveyed and certified; carriers reject bookings on estimated numbers.

Frequently asked questions

Flat rack or breakbulk — which is cheaper for oversized cargo?
For pieces that fit a flat rack (even with moderate OOG), container service is usually cheaper and far more frequent. Breakbulk wins for pieces beyond ~40 t or extreme dimensions.
Can flat racks be stacked when empty?
Collapsible-end units fold flat and interlock — typically 4 folded units travel in one 40ft slot, which keeps repositioning costs down.
