2022 Caterpillar Underground Mining (LHD) Loaders R2900G
The R2900G underground loader is designed for high production, low cost-per-ton loading and tramming in underground mining applications. Compact design with agile performance, rugged construction and simplified maintenance ensures excellent productivity, long life and low operating costs. Engineered for performance, designed for comfort, built to last.
Features may include:
Power Train – Engine- The Cat C15 ACERT engine provides unequalled lugging force while digging, tramming and traversing steep grades. Torque rise effectively matches transmission shift points for maximum efficiency and fast cycle times. Mechanically Actuated, Electronic Unit Injection (MEUI™) high-pressure, direct injection fuel system electronically monitors operator demands and sensor inputs to optimize engine performance. Air-to-air aftercooling provides improved fuel economy by packing cooler, denser air into cylinders for more complete combustion of fuel and lower emissions. Oil coiled pistons increase heat dissipation and promote longer piston life. The crankshaft is forged and induction hardened for long-term durability. The VR Package incorporates selective engine hardware and software to minimize diesel particulate matter in the engine exhaust. Engines equipped with the VR Package feature a significant ventilation rate reduction, a decrease in fuel consumption, and maintained or improved product performance. VR Package availability is subject to regional regulatory compliance. A Cat Diesel Particulate Filter can be used with the VR engine package. The filter compliments the VR engine by further reducing particulate matter in the exhaust. Requires the use of 15 PPM ultra low sulfur diesel and CJ-4 low ash engine oil.
- POWER SHIFT TRANSMISSION
- The Cat four-speed planetary power shift transmission is matched with the Cat C15 diesel engine to deliver constant power over a wide range of operating speeds.
- ROBUST DESIGN
- Designed for rugged underground mining conditions, the proven planetary power shift transmission is built for long life between overhauls.
- TORQUE CONVERTER LOCKUP CLUTCH
- Combines maximum rimpull while in torque converter drive with the efficiency and performance of direct drive when the lockup clutch is engaged. The lockup clutch delivers more power to the wheels for superior power train efficiency.
- ELECTRONIC AUTO SHIFT TRANSMISSION
- The electronic auto shift transmission increases operator efficiencies and optimizes machine performance. The operator can choose between manual or auto shift modes.
- TRANSMISSION NEUTRALIZER
- Using the left brake pedal, the operator can engage the service brakes and neutralize the transmission, maintaining high engine rpm for full hydraulic flow, enhancing digging and loading functions.
- ENGINE OVER SPEED PROTECTION
- The engine over speed control system will control the engine to a pre-set RPM to prevent an engine over speed event from occurring. It achieves this by modulating the service brakes to slow the machine down therefore reducing the engine RPM.
- DIFFERENTIAL
- No spin rear differential reduces tire wear and maximizes traction in uneven terrain.
- HYDRAULIC SYSTEM
- Powerful Cat hydraulics deliver exceptional digging and lifting forces for fast cycle times.
- LIFT AND TILT SYSTEM
- High hydraulic flow rates provide fast hydraulic cylinder response and powerful lift forces. Large-bore lift and tilt cylinder delivers exceptional strength, performance and durability.
