CAT 18: transport dimensions, weight and how it ships overseas

At 74,300 lb (33,713 kg), the CAT 18 is heavier than one container can carry, so it ships whole on a 40 ft flat rack (3 ft 4 in / 1.01 m over width, 5 ft 11 in / 1.8 m over height). RoRo is the alternative where a lane serves your port.

Every way to ship a CAT 18, best first

Worked out from the dimensions above against container, flat rack and RoRo limits. RoRo depends on a regular sailing to your port.

Preparing a CAT 18 for export

  • Tier 4 Final and Stage V engines need ultra-low-sulfur diesel (15 ppm or less) and DEF. Where only high-sulfur diesel is sold, the after-treatment clogs, so check fuel quality or source a lower-tier export machine.
  • Telematics (such as Cat Product Link, Komtrax or JDLink) may stop working abroad; the dealer can transfer or end the subscription before export.

CAT 18 shipping questions

Does a CAT 18 fit in a shipping container?

At 74,300 lb (33,713 kg), the CAT 18 is heavier than one container can carry, so it ships whole on a 40 ft flat rack (3 ft 4 in / 1.01 m over width, 5 ft 11 in / 1.8 m over height). RoRo is the alternative where a lane serves your port. It can also be containerized after disassembly (moldboard off, ripper off, cab or ROPS removed and crated, wheels off, and frame split at the articulation), across at least 2 containers by weight; we survey it first and quote both.

How much does a CAT 18 weigh for shipping?

Caterpillar lists the CAT 18 at 74,300 lb (33,713 kg) (operating weight); the bill of lading uses your machine's own weight.

What are the shipping dimensions of a CAT 18?

39 ft 6 in × 11 ft 2 in × 12 ft 3 in (12.05 × 3.41 × 3.75 m) (length × width × height) in transport position, from Caterpillar's published specifications for the CAT 18.

What has to come off a CAT 18 to ship it?

To containerize it: moldboard off, ripper off, cab or ROPS removed and crated, wheels off, and frame split at the articulation. Our crew does the work, crates and labels every part, and loads the pieces across at least 2 containers, with documentation for reassembly. Shipped whole on a flat rack or RoRo, it needs little or no disassembly.

Can a CAT 18 ship RoRo?

Yes, where a RoRo lane serves your destination port. It drives on under its own power. RoRo from the U.S. reaches fewer countries than containers and flat racks, so we check your port first.
