R2900 XE Underground Diesel-Electric LHD Loader


Built on the platform of our most popular underground loaders, the new R2900 XE is the first Cat® diesel electric underground LHD. It’s a productive, powerful, reliable machine built to meet the underground mining industry’s need for bigger payloads, faster loading and reduced emissions.
Its powerful diesel electric drive engine is EU Stage V compliant, and it offers the power to match its class-leading 18.5-tonne . The R2900 XE is highly productive, with smooth and quick machine responses combined with improved digging and tramming performance. Employing electric drive components reduces fuel burn and improves productivity — helping mines reduce greenhouse gas emissions and carbon footprint.
