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. 

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 labor 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:

• Customer Back 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. 

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.
