Cat R2900 XE®

Underground DieselElectric LHD Loader

Built on the platforms of our most popular load haul dump (LHD) models, the R2900 XE is the first diesel electric underground LHD forCaterpillar. R2900 XE is highly productive with smooth and quick machine responses together with improved digging and tramming
performances. Employing electric drive components results in fuel burn reductions and improved productivity, helping customers reducegreenhouse gas emissions and carbon footprints.

Heavy Structures

Bucket and Ground Engaging Tools (GET)• Frame Design – leveraging proven designs.
• Flipped articulation hitch to improve durability and service life.
• New front frame with a lower mounted Y pin to improve breakout.
• Redesigned Z-bar Loader Linkage geometry generates powerfulbreakout forces and an increased rack back angle for better bucket
loading and material retention. Heavy duty steel lift arms with caststeel cross tube ensures extreme loads encountered during loading
and tramming are efficiently dissipated for long service life.
• Sealed colleted pins are fitted to all major bucket and lift arm hinge
points for longer pin and bushing life.

• Four bucket sizes available: 7.4 m 3 (9.7 yd 3, standard), 8.6 m 3(11.2 yd 3), 9.2 m 3 (12.0 yd 3), 9.8 m 3 (12.8 yd 3).
• Full range of Cat GET offering to achieve best productivity while
maximizing bucket life.

Designed for Ease of Maintenance and Repair
to Minimize Downtime and Cost
• Fewer moving parts than traditional torque converter andmechanical transmission systems (benefit of electric drive).
• Extended maintenance intervals over mechanical power trains(benefit of electric drive).
• Single bolt in fuel tank with ground level access for easy
maintenance.
• Three points of contact at all locations, and flat folding handrails.
• Cold side ground level serviceability of engine.
• All filters are located vertically allowing for spill free servicing.
Radial seal air filters are easy to change/maintain.
• Fluid level checks are made easier with sight gauges visible fromground level.
• Electrical connectors are sealed to lock out dust and moisture.
Harnesses are covered for protection. Wires are color and number
coded for easy diagnosis and repair.
• Scheduled Oil Sampling (S·O·S SM) helps avoid minor repairs
becoming major ones. Sample point adapters fitted standardto machine.
• Tow hook design is bolt on, removable and triggers secondary
steering on use.
• Radiator guard swings open to allow service access.
• Added remote mounted test ports for testing and troubleshooting.
• Brake bleeder points in centralized locations.

Engine and Power Train• The R2900 XE employs a high-efficiency electric drive system, which
replaces the traditional mechanical transmission in the R2900.
• The efficient Cat ® C15 engine will be provided in EU Stage V or Tier 2
configurations and diesel particulate filtration.
• Revolutions Per Minute (RPM), fuel burn, heat generation andexhaust emissions have all been reduced, while offering an
increase in power.
• Cat Switched Reluctance Electric Drive System benefits include:– Improved power and cycle times.
– Continuously variable speed control.
– Implemented virtual gears for machine controllability.
– Automatic retarding controls for maintaining speed on grade.
– Anti-roll back feature.
– Smoother directional changing, no driveline or power train
shock loads.
– Speed management can be programmed, allows improved
operator efficiency and reduced fatigue.
– Neutral creep and coasting inhibitor.
– Torque control reduces brake application.
• Cat Integrated Powered Electronics are fully sealed to protectfrom the elements.

The Latest Technology Delivers Optimum
Productivity and Efficiency

Cooling System• Cat Minestar™ for Underground Technology ready.
• Autodig function to optimize loading and traction control
to maximize tire life.
• Payload Monitoring.
• Product Link™ Elite (PLE) system for machine health monitoring.
• Scalable levels of remote operation from Line of Sight (LOS)
through to full automation.

• High Efficiency Radiator as Optional Cooling Package.
