Caterpillar Unveils Largest Underground Loader Yet
The CAT R3200 XE LHD adds a 25-ton payload and an electric drive system to Caterpillar's underground load-haul-dump lineup.
Updated on Nov. 10, 2026 in Trucks
Caterpillar has unveiled the CAT R3200 XE LHD, its largest underground load-haul-dump machine to date, with a 25-ton payload. The machine uses an 18.1-liter Tier 5 C18 diesel generator producing 527 hp to power an electric drive system.
Why it matters
The machine targets underground mining operations that need higher haulage capacity and lower operating costs. Its performance gains over the prior R2900 XE address efficiency pressures from rising fuel prices.
The R3200 XE LHD carries a 25-ton payload, is 18 tons larger in class than the R2900 XE, and offers 11% better speed on grade. Full official specifications have not yet been published.
The players
Caterpillar
Caterpillar is a major American manufacturer of construction and mining equipment, known for its heavy machinery lineup including underground mining loaders.
The details
The R3200 XE LHD includes redesigned axles for durability, the latest CAT AutoDig and MineStar software, and support for remote, semi-autonomous, and fully autonomous operation through Command for Underground. It shares its electric drive system with the R2900 XE.
Timeline
August: fuel prices rose 27.4% in a single month.
November 10, 2026: the unveiling of the R3200 XE LHD was published.
Roadmap
The R3200 XE LHD extends Caterpillar's R2900 XE underground loader line into a larger size class. It reflects a continued push for higher productivity and automation in underground mining equipment.
For mine operators, the 28% productivity gain and 8% fuel efficiency improvement could reduce per-ton haulage costs. Buyers should weigh these figures against the generator-and-electric-drive setup when planning fleet upgrades.
The takeaway
Operators evaluating underground haulage should compare the R3200 XE's productivity and fuel figures against their own site conditions once full specifications are released.
