Choosing the wrong shipping method is the most expensive mistake in heavy-equipment logistics. Here's a clear framework for the three main options.
RoRo (Roll-on/Roll-off)
Cargo is driven or towed onto a dedicated vessel and secured on its wheels or tracks.
- Best for: running, self-propelled, wheeled units — cars, trucks, wheel loaders, mobile cranes.
- Pros: usually the most economical for eligible cargo; no container packing.
- Cons: the unit must roll and steer; limited cargo protection; port availability varies.

Container (standard, high-cube, or dismantled)
Cargo is loaded into an enclosed box — assembled if it fits, or knocked down if it doesn't.
- Best for: parts, attachments, smaller machines, and anything that benefits from enclosed protection or more frequent sailings.
- Pros: best protection; most sailings; easy inland moves.
- Cons: size limits; possible dismantle/reassembly cost. Use the container space calculator to check fit.
Flat rack / open top
Specialized container equipment for out-of-gauge pieces, crane- or forklift-loaded and lashed down.
- Best for: single over-width or over-height pieces that can't be knocked down to fit a box but don't need full breakbulk.
- Pros: keeps the frequency and handling benefits of container service for OOG cargo.
- Cons: more expensive than standard boxes; requires proper lashing and surveys.
A simple decision guide
| Question | If yes |
|---|---|
| Does it run, roll, and steer? | RoRo is likely cheapest |
| Does it fit (or knock down to fit) a box? | Containerize |
| Is it a single over-gauge piece that can't be knocked down? | Flat rack / open top |
| Is it indivisible and massive? | Breakbulk heavy-lift |
