Underground mine trucks

For Worldwide Release: September 2021

Built on the company’s most popular load haul dump (LHD) platforms, the Cat® R2900 XE LHD will feature a diesel electric drive system that delivers high productivity, smooth and quick machine response, and improved digging and tramming performance.

Allowing MINExpo 2021 attendees to see inside the new diesel electric drive design, slated for commercial availability in 2023, an R2900 XE drivetrain is a part of the Caterpillar Underground display. The exhibit emphasizes the model’s high-efficiency Switch Reluctance (SR) electric drive system and redesigned axles, wheel and brake groups.

Increasing payload more than 9% over the Cat R2900G, the R2900 XE offers an 18.5-tonne (40,785-lb) rated loading and tramming payload for a 3- to 4-pass match with the Cat AD63 truck. The electric drive system delivers 52% faster acceleration and improved machine response, while reducing fuel consumption by more than 30% in many applications. The redesigned lift arm and components geometry, combined with load-sensing hydraulics and new bucket geometry, increase the R2900 XE’s breakout force by 35%.

More information on the new R2900 XE diesel electric LHD can be found by talking to an Underground show worker during MINExpo 2021 from September 13-15 in Caterpillar’s Central Hall exhibit, #6229, at the Las Vegas Convention Center.
