Hyundai launches R220LC-9A crawler excavator featuring increased speed, power, redesigned cab

The 49,640-pound excavator features a 20-foot 5-inch max dig depth, and a 29,980-pound bucket breakout force.
Equipped with a 157-horsepower Cummins Tier 4 Interim engine, the R220LC-9A also features a VGT turbocharger that varies airflow boost to match engine rpm and load demands. Cummins’ Direct Flow air filter ensures fast cycle times and improved fuel economy compared to previous models, and a variable speed fan clutch, two-stage auto decel system and economy mode conserve fuel and reduce environmental impact.
Three engine modes are available. The machine’s hydraulic system offers super fine touch and controllability, and features such as improved hydraulic valves, precision designed variable volume piston pumps, fine touch pilot controls and enhanced travel functions ensure smooth operation.
Several new features increase speed and power – a new auto boom, swing priority system, auto power boost feature and improved arm-in and boom-down flow regeneration system.
A newly designed cab has more space, an improved field view and improved operation comfort. A see-through upper skylight, large one-piece right side glass, closeable sunshade and reduced front window seam boost visibility, and creature comforts such as adjustable seats and settings reduce fatigue and improve the operator experience.
Ground level access to filters, fittings and components simplify serviceability, and extended service intervals further reduce maintenance.
