In the world of construction equipment, efficiency and reliability remain the most critical requirements for users. Operating in remote, rugged mountainous terrain presents significant challenges when equipment suffers from excessive fuel consumption, inadequate stability, or frequent breakdowns. The Modern R220LC-9S crawler excavator addresses these challenges head-on with exceptional fuel efficiency, robust adaptability, and reliable performance.
Superior Performance Through Precision Engineering
As a premium model in Modern Construction Equipment's product line, the R220LC-9S embodies a design philosophy centered on efficiency, safety, and reliability. Weighing 21.9 tons, this excavator delivers impressive digging and traction power, with bucket digging force reaching 133.4 kN (2m arm) and arm digging force of 144.2 kN (2m arm), enabling efficient operation even in hard soil or rocky conditions.
Fuel Efficiency for Reduced Operating Costs
The R220LC-9S incorporates multiple advanced fuel-saving technologies, including a two-stage automatic deceleration system and an efficient economy mode that automatically adjusts engine speed and hydraulic output based on working conditions. Equipped with a Tier 2-compliant HM 5.9 engine delivering 107 kW at 1950 RPM, the excavator achieves remarkable fuel economy with average consumption rates of 15.0 L/h in economy mode, 16.62 L/h in standard mode, and 18.17 L/h in power mode.
Enhanced Stability for Challenging Environments
The excavator's extended undercarriage design features nine carrier rollers per side for improved stability on uneven terrain. Additional design elements include tapered side frames for easier debris removal, polyurethane-sealed track chains to prevent dirt ingress, and bolt-connected safety platforms, all contributing to durability in harsh conditions.
Intelligent Control Systems
Operators benefit from advanced control systems featuring a color LCD display and toggle switches for customized machine settings. The Computer-Aided Power Optimization (CAPO) function automatically selects optimal hydraulic flow balance for smoother operation and reduced fuel consumption.
Simplified Maintenance Design
Key components and lubrication points are positioned for ground-level access, significantly reducing maintenance time and costs while extending equipment lifespan.
