Following an 18-month autonomous hauling pilot program at Luck Stone's Bull Run Quarry, Luck Stone and Caterpillar are expanding the technology to two additional Virginia operations. The expansion builds on proven results at Bull Run, where autonomous trucks have hauled more than 3.5 million tons since going live in November 2024.
Quarry and aggregates producers across the industry face persistent operational challenges: maintaining consistent production across shifts, improving safety, and attracting and developing talent in a competitive environment. For Luck Stone, technology is most valuable when it helps associates become the best versions of themselves while creating safer, more consistent operations. That's why Luck Stone sought a partner whose approach to autonomy puts people at the center of innovation.
Through close collaboration in development and implementation, Luck Stone has seen firsthand how Caterpillar's approach to combining technology, people, and process can improve safety, increase production consistency, and create new opportunities for associates to develop new skills and grow into technology-focused roles.
Delivered by Caterpillar and supported by local Cat dealer Carter Machinery, the expansion will integrate Caterpillar's autonomous hauling technology across two fleets of Cat 775 trucks at Boscobel and Bealeton, alongside complementary technologies that support loaders and other site equipment. This marks the first time Caterpillar will deploy its autonomous haulage solution on the Cat 775, a key haul truck model in the quarry industry.
The Luck Stone expansion is the latest milestone in Caterpillar's growing momentum in quarry autonomy. Collectively, Caterpillar autonomous trucks have hauled more than 13 billion tonnes and safely traveled more than 455 million kilometers with no reported injuries while operating.
"At Luck Stone, we've always believed innovation should ignite human potential," said Travis Chewning, Luck Stone vice president of engineering and operations support. "Autonomy is creating a safer workplace that improves consistency for our customers and gives our associates opportunities to develop new skills as our industry continues to evolve. Our collaboration with Caterpillar has helped us do exactly that, and we're excited to continue building on what we've learned at Bull Run."
"Our mission at Caterpillar is to solve our customers' toughest challenges, and customers like Luck Stone play an important role in helping us advance solutions for the broader industry," said Denise Johnson, Caterpillar group president, Resource Industries. "By working together, we've gained insights that help us refine and scale autonomous hauling solutions that create measurable value for both operations and workforce development. This expansion demonstrates how strong customer collaborations are helping us accelerate innovation and bring proven solutions to more job sites around the world."
