Luck Stone celebrates one million tons of aggregates hauled autonomously
A fleet of Cat 777 hauling trucks is supported by full autonomous technology
Luck Stone and Caterpillar have reached a major milestone in their collaboration: one million tons autonomously hauled at Luck Stone's Bull Run Quarry in Chantilly, Virginia.
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.
A strategic relationship built on innovation
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.
Why one million tons matters
Reaching the one million tons hauled autonomously milestone confirms that autonomous haulage can deliver consistent, repeatable performance. It also signals how autonomous solutions will address skilled labour shortages, improve site safety, increase operational efficiency, and upskill quarry employees to run autonomy.
This milestone aligns with Caterpillar's enterprise strategy in several key areas:
- Contractor backed solutions: Luck Stone's operational insights helped shape the deployment and refinement of the AHS.
- Productivity: Autonomous trucks have demonstrated improved cycle consistency and reduced idle time.
- Safety: Removing operators from the cab reduces exposure to potential hazards and enhances site control.
- Sustainability: Autonomy enables more efficient fuel use and supports emissions reduction goals.
"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.
"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.
