Bailey Pemberton September 16, 2026 3 min read CAT -3.33% Caterpillar (NYSE:CAT) expanded its autonomous hauling partnership with Luck Stone to additional quarry sites in the United States.

The rollout includes the first use of autonomous haulage on Cat 775 trucks specifically configured for quarry operations.

The partners are targeting gains in safety, production consistency and workforce development through wider use of automation across these quarries.

For readers who want more ideas linked to heavy equipment automation and AI logistics, the next stop is 60 AI infrastructure stocks .

Caterpillar, a machinery heavyweight with a reported market value of about $360.2 billion, builds the kind of large-scale construction and mining equipment that can directly use autonomous hauling systems in quarries.

The same portfolio of off highway engines and heavy trucks that powers global infrastructure projects also gives the group a testing ground for applying automation in real world material handling.

The big idea behind Caterpillar's Narrative is that heavy equipment is shifting from pure iron to technology plus services, with autonomy and electrification helping support multi-year demand and profitability, especially in infrastructure and mining.

This expansion with Luck Stone plugs directly into that story because it applies automation to a key quarry truck platform rather than a one-off pilot.

"Sustained mining equipment demand, cost controls, and growth in high-margin services drive long-term profitability and free cash flow improvement...

What the market may underplay here is how deploying autonomy on Cat 775 fleets can deepen Caterpillar's services and software footprint rather than just sell more trucks.

Every quarry that layers in autonomous hauling, loader tech and dealer support pulls more data, more maintenance work and more training needs into Caterpillar's orbit, an area rivals like Komatsu and Volvo are also targeting.

Automation tightens Caterpillar's link to mining and aggregates demand at a time analysts already flag tariff pressure, pricing competition and high capital intensity as weak points.

If customers hesitate on autonomy rollouts or favour cheaper alternatives, the same tech-heavy strategy that supports the Narrative could amplify earnings swings instead of smoothing them.

For investors, this kind of partnership only becomes useful once it is slotted into a broader Caterpillar Narrative that explains how autonomy, services and global risks fit into a single decision.

Quarry automation only tells you how Caterpillar is working today.
