Hyundai Construction Equipment Americas has announced the introduction of its newest crawler excavator, the R220LC-9A. This new mid-size excavator provides operators with a certified Interim Tier 4 engine upgrade, improved hydraulics, increased operator comfort and added durability. This model is ideal for mid-size excavating projects, road and utility work and demolition. The R220LC-9A will join Hyundai’s new line of 9A series excavators, all of which meet Tier 4 Interim standards.
Powering the R220LC-9A is a low emission, low noise, 157 hp (117 kW) Cummins Interim Tier 4/Stage IIIB, QSB6.7 engine. This engine is complemented by a patented VGT Turbocharger, which continuously varies the airflow boost to precisely match engine RPM and load demands for optimal performance. The engine also features the Cummins Direct Flow™ air filter which delivers better performance with faster cycle times and improved fuel economy over previous models. The R220LC-9A’s variable speed fan clutch, two-stage auto decel system and the economy mode help to conserve fuel and reduce environmental impact. Plus, operators can choose between three unique engine modes – Power, Standard and Economy – which enable the machine to switch between full power and reduced fuel consumption according to the user’s preference.
The R220LC-9A boasts an operating weight of 49,640 lbs (22.5 tonnes), a maximum dig depth of 20’5” 6.2 metres) and a bucket breakout force of 29,980 lbs (13.6 tonnes).
To achieve optimum precision, Hyundai redesigned the R220LC-9A’s hydraulic system to provide the operator with super fine touch and controllability. Improved hydraulic valves, precision-designed variable volume piston pumps, fine-touch pilot controls and enhanced travel functions make for smooth operation regardless of the operator’s experience level. Other innovations include a new auto boom and swing priority system for optimum speed, a new auto power boost feature for additional power when needed and an improved arm-in and boom-down flow regeneration system for added speed and efficiency.
