“We are using the lessons learned from working with our U.S.-based customer, Luck Stone, where we have MineStar Command for hauling installed on four Cat 777 trucks,” said Denise Johnson, Group President of Caterpillar Resource Industries. “The shift to the aggregate industry, where we are automating fewer trucks that don’t haul material 24 hours a day, is helping transform our technology and processes to manage smaller operations.”

Caterpillar's work with Luck Stone has demonstrated significant benefits, such as enhancing safety by minimizing interactions with heavy equipment, upskilling personnel with new technologies, and improving consistency and efficiency at the Bull Run quarry. Since November, the autonomous fleet at Bull Run has safely moved over 816,000 tonnes (900,000 tons) and has enabled more day-to-day consistency and flexibility in scheduling production.

Quarry operators like Luck Stone are increasingly motivated to adopt autonomous hauling to enhance safety by removing operators from harm’s way and ensuring safe interactions between staffed and autonomous machines. Additionally, it improves operational consistency by reducing the variability of haulage operations from shift to shift and during shifts.

The Cat 775 next generation truck has a planned introduction in 2026. Autonomous capabilities with MineStar Command for hauling are currently under development, and a release date will be announced at a later date.

Leveraging more than 30 years of autonomous innovation and experience, Caterpillar is transforming quarry operations with the Cat MineStar Command for hauling. In addressing the unique challenges of the mining and quarry industries, Caterpillar remains committed to enhancing safety and productivity to help customers build a better, more sustainable world.
