Hyundai Construction Equipment Americas Inc. has added two new production class crawler excavators to its product line-up: the R480LC-9A and the R520LC-9A. These new excavators feature a certified Interim Tier 4 engine upgrade, improved hydraulics, increased operator comfort and more durability.

Hyundai has powered each of these 9A earth movers with a low emission, low noise, Cummins Interim Tier 4/Stage IIIB QSX11.9 engine. This engine has one of the highest power-to-weight ratios in its class, and its torque rise (up to 50 percent) enables the engine to quickly take full advantage of the torque power. Other innovations such as the 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 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.

Both models also come with a redesigned hydraulic system which provides the operator with super fine touch and improved controllability.

Hyundai has improved the structure strength of the 9A series cabs with stronger but slimmer tubing for optimum safety and visibility. High-strength steel forms a more durable upper and lower frame. In addition, the enlarged cab comes with a see-through upper skylight, a larger and one-piece right-side glass, safety glass windows on all sides that won’t scratch or fade, a closeable sunshade and a reduced front window seam.

Each model comes standard with a newly designed color LCD display cluster with easy to read digital gauges for monitoring temperature, fuel levels and other maintenance items. The simplified design allows the operator to easily adjust engine power and work modes, set boom speed and arm regeneration, view what’s happening behind them with the optional rear-view camera, and protect the machine with the new password anti-theft system.

The Hi-mate Remote Management System allows operators and dealer service personnel to access a machine’s vital service and diagnostic information from anywhere with Internet access. Hi-mate users can remotely monitor daily reports outlining a machine’s location, working hours, fuel consumption and any periodical maintenance needed, drastically reducing downtime and saving the owner time and money.
