Autonomous haul trucks and Poland's nuclear power: a week when the industry thought in big numbers

Autonomous Cat 775s conquer more Luck Stone quarries [1]

Caterpillar and American aggregates producer Luck Stone are expanding their autonomous hauling program to two more sites in Virginia – Boscobel and Bealeton. The fleet is built around Cat 775 trucks with a payload capacity of 71 tons, smaller than the flagship models used in autonomous projects so far. This is an interesting signal – driverless bulk material transport technology is moving down into lighter weight classes, reaching an ever-wider group of mine and quarry operators, including smaller ones for whom investing in full autonomy had until now seemed too costly.

The decision to expand the program followed a successful pilot at the Bull Run mine, where autonomous haul trucks have already moved more than 3.5 million tons of material since November 2024. This shows we're not talking about a one-off technological experiment, but a solution proven in day-to-day operations that genuinely shortens haul cycles and cuts labor costs. Importantly, the program's expansion isn't limited to trucks alone – Caterpillar is simultaneously rolling out assistance systems for loaders and other equipment operating on mine sites, supported by the brand's local dealer, Carter Machinery, which shows that autonomy is spreading across the entire work environment, not just individual machines.

For the whole construction and mining equipment industry, this is a signal that autonomy is no longer a novelty showcased at a single flagship site, but is becoming a standard part of fleet equipment in many locations at once. The question that naturally arises is: who will follow in Caterpillar and Luck Stone's footsteps fastest – and will we soon see similar deployments at European mines and quarries too, where the pressure for efficiency and workplace safety is just as high?
