Cat® R2900 XE - Diesel Electric Underground Loader

Faster, more efficient, and more powerful.

The first diesel electric underground loader from Caterpillar, the Cat® R2900 XE LHD, aims to meet the underground mining industry’s needs for bigger payloads, faster loading and reduced emissions. Built on the platform of Caterpillar’s most popular underground loader, this new LHD features optimized lift arm and component geometry plus load-sensing hydraulics to improve breakout force by 35% over the Cat R2900G.

The R2900 XE works faster in tough conditions, delivering 52% quicker acceleration and improved machine response over the R2900G. It accelerates from 0-24 km/h (0-14.9 mph) in 6.4 seconds and achieves a 7% higher speed on grade. Variable piston pumps deliver higher flow rates for faster hydraulic cylinder cycle times and powerful lift forces. Boasting a higher, 18.5-tonne (20.4-ton) payload for faster load times, the new model offers a 3- to 4-pass match to the Cat AD63 truck for greater efficiency. Combined, these features deliver a 20% increase in productivity for the R2900 XE.

Drawing from decades of experience, the R2900 XE features a proven switch reluctance electric drive system. It is Caterpillar designed, integrated, validated, and supported, and its continuously variable speed control delivers improved power and cycle times. With no driveline or powertrain shock loads, it offers smoother directional changing and implemented virtual gears for machine controllability. Automatic retarding controls maintain speed on grade. The drive system prevents coasting in neutral and combines with the anti-rollback feature to further increase operating safety.

Redesigned buckets are available in four sizes with capacities ranging from 7.4 to 9.8 m3 (9.7 to 12 yd3). Along with the full range of Cat ground engaging tools, to further protect the bucket, a range of heel shrouds, wear plates and bars are available in weld-on or mechanically attached designs.
