Heavy equipment giants Caterpillar have signed an agreement with Vale that will see the company dramatically expand its fleet of autonomous haul trucks deployed at iron ore operations in the Carajás region of Brazil over the next three years.
Vale’s Northern System mining operation currently has 14 CAT, 320-ton autonomous haul trucks in service. With this new deal, sold by Caterpillar’s Brazilian dealer, Sotreq, the autonomous haul truck fleet will expand to some ninety (!) of the massive, self-driving trucks by 2028. The big yellow trucks will be operated by CAT®, MineStar™ Command for hauling, and ship with a payload capacity of between 240 to an almost unimaginable 400 (!!) tons.
“We’re proud to introduce Cat Command for hauling at Vale’s Carajás site,” says Marc Cameron, Senior Vice President at Caterpillar. “By equipping Vale’s haul trucks with our autonomous technology, we will be delivering scalable solutions that meet their needs across a mixed fleet.”
CAT says this new deal represents, “a transformational leap,” citing the fact that autonomous trucks remove workers from hazardous areas and enable safer and more inclusive environments for mine employees – and more efficient operations for Vale.
That fact is backed by results from other Vale operations that have deployed large numbers of autonomous vehicles, which saw gains of up to 15% in operational performance and a 7.5% reduction in fuel use (more with electric drive), contributing to the reduction of the company’s carbon emissions. And, because this is end-stage capitalism 2025, they’re crediting AI for discovering those efficiencies.
“By integrating autonomous systems, artificial intelligence, and advanced data analysis, we are modernizing our mining operations in the Northern Corridor, becoming a global benchmark in smart mining, promoting the transformation of the industry, and connecting us to international best practices,” says Rafael Bittar, Vale Vice President, Technical.
The trucks will be delivered over the next three years, and are expected to be in full operation and up to speed by 2030.
Electrek’s Take

As I’ve said before, EVs and mining to together like peanut butter and jelly. In confined spaces, the carbon emissions and ear-splitting noise made by conventional, ICE-powered mining equipment can create dangerous circumstances that can lead to serious injuries (or worse), and that’s just going to make it even harder for a mining operation to keep people working and minerals coming out of the ground.
By working with companies like Caterpillar to prove that forward-looking electric equipment can do the job as well as well as (if not better than) their internal combustion counterparts, Vale will go a long way towards converting what’s left of the ICE faithful.
