- Komatsu launched the PC9000-12, the largest hydraulic excavator in the company's history, capable of moving 80 tons of material per pass at over 8,000 tons per hour.
- Komatsu first deployed the PC9000-12 at Suncor's Fort Hills oil sands mine in Alberta, Canada in May 2024, and the machine is now available globally through its dealer network as of April 2.
- Komatsu configured the excavator with grid-connected electric drive drawing current equivalent to nearly 20 Tesla Superchargers, powering a pair of motors that output 4 MW — over 5,300 hp.
- Komatsu designed the PC9000-12 for double-side loading and integrated it with its FrontRunner Autonomous Haulage System to minimize additional operators and speed repetitive tasks.
- Peter Buhles, Komatsu VP of Sales and Service, said the PC9000-12 'sets a new benchmark for global surface mining operations' with face shovel, backhoe, diesel, and electric drive configurations.
- IDTechEx estimated that a single 150-ton haul truck burns over $850,000 in fuel annually, underscoring the cost-savings pitch for electrifying heavy mining fleets.
Why it matters: With mining's heaviest equipment now available in electric-drive form and a single 150-ton haul truck burning $850,000 in fuel per year per IDTechEx, operators running the PC9000-12 via grid power can slash fuel costs and emissions at scale — making the world's largest excavators a concrete test case for electrifying the dirtiest industrial work sites.
