Hyundai Construction Equipment Americas Inc. has added three new construction class crawler excavators: the R300LC-9A, 330LC-9A and 380LC-9A. These new earthmovers feature a certified Interim Tier IV engine upgrade, improved hydraulics, increased operator comfort and more durability, according to the manufacturer.

These excavators are practical for mid and large size excavating projects, site preparation, pipeline installation, road and utility work or demolition. Like the rest of Hyundai’s new 9A series, all three machines meet Tier IV Interim standards.

The R300LC-9A, 330LC-9A and 380LC-9A boast respective operating weights of 65,700, 72,750 and 86,200 lb. (29,801, 33,000 and 39,099 kg).

Hyundai has powered each of these 9A excavators with a low emission, low noise, Cummins Interim Tier IV/Stage IIIB engine. (a QSB6.7 for the 300LC-9A, a QSC for the 330LC-9A and a QSL9 the 380LC-9A). All engines are complemented by Cummins’ VGT Turbocharger, which continuously varies the airflow boost to precisely match engine rpm and load demands for optimal performance. 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 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.

Hydraulic system technologies make the 9A series excavators fast, smooth and easy to control. The R300LC-9A, 330LC-9A and 380LC-9A come with a redesigned hydraulic system which provides the operator with super fine touch and improved controllability, according to the manufacturer.

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 — all features that work together to improve visibility.

In addition to enhanced safety and visibility, operators will enjoy the ability to fully customize the cab of the R300LC-9A, 330LC-9A and 380LC-9A to best fit their needs. Operators can easily adjust the seat, console and armrest settings. Hyundai has integrated the seat with the console to reduce operator fatigue, and adjustable air-suspension comes standard. Sleek styling has been applied to the ergonomic joysticks, which are now height-adjustable.

Hyundai’s engineers made sure that the 9A cabs include many amenities that decrease stress and increase comfort. Some of these features and benefits include heated seats, additional space, enhanced climate control system, advanced audio system with USB player, AM/FM stereo and MP3 capabilities. An optional add on is a smart key system that allows the operator to start the ignition with the push of a button.

The R300LC-9A, 330LC-9A and 380LC-9A come 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.

Like all of Hyundai’s 9A series equipment, the R300LC-9A, 330LC-9A and 380LC-9A feature the Hi-mate remote management system, which 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.

Hyundai’s 9A-series excavators offer bushings designed for extended lube intervals of 250 hours — and polymer shims to resist wear and reduce noise. Included also are extended-life hydraulic filters (1,000 hours), long-life hydraulic oil (5,000 hours) and more efficient cooling systems and integrated preheating systems, according to the manufacturer.
