Hyundai Construction Equipment Americas Inc. recently unveiled its R220LC-9A Amphibious excavator. This mid-size excavator is equipped with amphibious undercarriage designed for wet environments like swamps and marshes. This versatile machine is ideal for maneuvering in soft terrain whether it’s dredging a waterway or doing construction in wetlands.

The R220LC-9A Amphibious excavator features hydraulic extendable pontoons constructed with premium grade steel that are designed for floatation on water. This model features a proprietary design using multi-synchronous hydraulic motors on each pontoon. Multiple active motors are provided to propel each pontoon for sufficient power making it virtually undeterred in any terrain. Optional supplementary pontoons can be added on each side of the machine to boost stability in deeper water to a maximum of 14.1 feet. Optional spuds can be attached to supplementary pontoons to help overcome buoyant force and offer added stability and enhanced operation.

The R220LC-9A Amphibious model is equipped with track shoes/cleats that are robotically welded for the utmost precision. Each pontoon comes with three strands of heavy-duty track chains, constructed with high yield strength tensile steel.

Hyundai’s 22-ton class R220LC-9A Amphibious excavator boasts a 20-ft, 8-in. arm and a maximum dig depth of 34 ft. 11 in.

To achieve optimum precision, Hyundai designed this model’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.

In addition to providing maximum performance, Hyundai’s R220LC-9A Amphibious excavator is built to last. This model also has improved cab structure strength with stronger but slimmer tubing for optimum safety and visibility. Low stress, high strength steel is integrally welded to form a stronger, more durable upper and lower frame.

The R220LC-9A Amphibious is not only durable but was engineered for the utmost safety and visibility. This model has a newly designed cab for more space, a wider field view and enhanced operator comfort. Special attention was given to a clear, open and convenient interior with plenty of visibility on the machine surroundings and the job at hand. This well-balanced combination of precision aspects puts the operator in the perfect position to work safely and securely. 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 R220LC-9A Amphibious 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. For a more enjoyable work environment, the R220LC-9A Amphibious offers many amenities that decrease stress and increase comfort. These include heated seats, additional space, enhanced climate control system, advanced audio system with USB player, AM/FM stereo, MP3 capabilities and hands-free Bluetooth. An optional feature is a Smart Key System, which allows the operator to start the ignition with the push of a button.

The R220LC-9A Amphibious comes standard with a newly designed, color, 7-in. touch screen LCD display with easy to read digital gauges for monitoring temperature, fuel levels and other maintenance items. Power and work mode selection, self-diagnostics, an optional rear-view camera, maintenance check lists, start-up machine security and video functions were integrated to make the machine more versatile and the operator more productive. The display is capable of tilting 15 degrees horizontally and 30 degrees vertically to meet the operator’s preference and to avoid sun glare.

Maintenance is painless with easy access to filters, lube fittings, fuses, machine computer components and wide open compartments. Three watertight compartments are sealed with individual manholes for easy inspection and maintenance. This model and the entire 9A-excavator series offer bushings designed for extended lube intervals of 250 hours and wear resistant, noise reducing polymer shims. Also provided are extended-life hydraulic filters (1,000 hours), long-life hydraulic oil (5,000 hours), more efficient cooling systems and integrated preheating systems, all of which help to extend service intervals thus reducing operating costs and machine down time.

Like all of Hyundai’s 9A series equipment, the R220LC-9A Amphibious features 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 promoting preventative maintenance to help save the owner time and money.
