Caterpillar and Luck Stone celebrate one million tons hauled autonomously at Bull Run Quarry

Caterpillar, Inc. and Luck Stone, the nation’s largest family-owned and operated producer of crushed stone, sand and gravel, announced a significant milestone in their ongoing collaboration: one million tons autonomously hauled at Luck Stone’s Bull Run Quarry in Chantilly, Virginia.

“This milestone is a powerful demonstration of what’s possible when we collaborate with our customers to deliver solutions for their critical needs. Reaching one million tons hauled autonomously at Bull Run shows that autonomy isn’t just for mining – it’s scalable, reliable, and ready to transform the aggregates industry. We’re proud to collaborate with Luck Stone to lead that transformation,” said Denise Johnson, group president, Resource Industries, Caterpillar.

The achievement marks a first for Caterpillar in the aggregates industry and underscores the success of
Caterpillar’s autonomous haulage system (AHS) in a quarry environment. The milestone demonstrates the
safety and productivity of autonomy beyond traditional large mining applications.

“At Luck Stone, our mission is to ignite human potential, and this project is an example of what’s possible
when people, purpose, and progress come together. We’re grateful to Caterpillar and confident that operators across the country will have a similar experience,” commented Charlie Luck, president and CEO, Luck Companies.

The collaboration between Caterpillar and Luck Stone began with a shared vision to transform quarry
operations through cutting-edge technology. Bull Run Quarry became the first site in the aggregates industry to deploy Caterpillar’s autonomous Cat® 777 trucks, supported by a full autonomy technology stack and site integration services.

Since the initial deployment, the collaboration has focused on validating autonomy along with the people and processes in conditions that are typical in quarry operations but distinct from mining.

Caterpillar and Luck Stone continue to explore opportunities to expand autonomy across additional sites and applications. The success at Bull Run sets a precedent for the broader aggregates industry and reinforces the companies’ commitment to innovation and operational excellence.
