Haul more, dump more with the Cat® 730 articulated truck. With a 31-ton (28-tonne) payload capacity, it’s designed to boost productivity—especially on compact jobsites. Pass-matched with Cat excavators and loaders, you can move more material efficiently and with less effort.
The redesigned dump body provides easier loading and maximum payload, while the C13B engine delivers the power you require, combined with relentless reliability.
Designed for safe and convenient access
with ground level service, and Dynamic Rollover Protection applies brakes when needed to help reduce the risk of rollovers.
Easily set job parameters with Body Height and Machine Speed Limiting, while achieving up to 16% more fuel efficiency with more dirt moved per fuel used.

| Note (1) | The declared dynamic operator sound pressure level is 70 +/- 1 when ISO 6396:2008 is used to measure the value for an enclosed cab. The measurement was conducted at 70% of the cooling fan’s maximum speed. The sound level may vary at different cooling fan speeds. The measurement was conducted with the cab doors and the cab windows closed. The cab was properly installed and maintained. |
