US: Heidelberg Materials North America says it has autonomously hauled more than 2Mt of limestone at its Lake Bridgeport Quarry in Texas over the course of the past eight months. It used an autonomous haulage system (AHS) supplied by Pronto. The building materials company said that this achievement reflects a significant milestone in the its journey to lead the building materials industry in digitalisation.
Following a pilot project at its Bridgeport Quarry in 2023, Heidelberg Materials North America deployed a mixed fleet of OEM haul trucks with Pronto’s AHS at its neighbouring Lake Bridgeport Quarry. The Lake Bridgeport site transported more than 2Mt of stone from the pit to the crusher over the course of eight months.
Heidelberg Materials says that the deployment shows how digital technology can improve efficiency, safety, environmental performance and increase productivity. The switch also helped local management cope with the challenge of recruiting skilled haul truck operators at the site.
“We are excited to mark this important milestone at our Lake Bridgeport Quarry,” said Chris Ward, President and CEO of Heidlberg Materials North America. “The successful deployment of Pronto’s AHS technology at Lake Bridgeport showcases our strong commitment to leveraging innovative and scalable solutions at our operations that contribute to enhancing efficiency and safety while also addressing the recruiting challenges we face at many of our operations across North America.”
