Hyundai's R140W-9A wheeled excavator.
Hyundai Construction Equipment Americas Inc. has added three new wheeled excavator models, the R140W-9A, R180W-9A and the R210W-9A, to its 9A series product line. These machines will provide operators with enhanced features and benefits compared to prior models including a certified Tier IV Interim engine upgrade, improved hydraulics, increased operator comfort and added durability. The R140/180/210W-9A models are mid-size excavators providing plenty of power and mobility to get the job done and are ideal for excavating projects, road and utility work and demolition, according to the manufacturer.
The R140W-9A, R180W-9A and R210W-9A have operating weights of 30,200 lbs. (13,700 kg), 38,100 lbs. (17,280 kg) and 45,200 lbs. (20,500 kg), respectively
Hyundai has powered each of these 9A wheeled excavators with low emission, low noise, Cummins QSB6.7 Interim Tier IV/Stage IIIB engines. Electronically controlled fuel injection and diagnostic capabilities add to the engines’ efficiency and serviceability. 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.
To achieve optimum precision, Hyundai redesigned the hydraulic system on each of these models to provide the operator with super fine touch and controllability. Improved pump flow control minimizes fuel consumption and improved spool valves are engineered to provide more precise flow to each function with less effort. Enhanced hydraulic valves, precision-designed variable volume piston pumps, fine-touch pilot controls and enhanced travel functions make for smooth and easy operation. Boom-down flow regeneration and control valve technology also are newly improved. An auto boom-swing priority feature automatically and continuously looks for the ideal hydraulic flow balance for the boom and swing motions of the machine to maximize performance and productivity.
In addition to power and efficiency, the R140/180/210W-9A wheeled excavators feature a new and improved travel system. An auto cruise control system reduces operator fatigue by maintaining a fixed speed when driving distances. A new auto ram lock system is available to improve operating safety by locking or releasing the ram cylinder according to the operating mode. An optional forward/reverse travel pedal control allows operators the choice of using the travel pedal control while in work mode or the lever while in control mode. A new creep speed travel system also is provided to improve maneuverability and fine control.
Hyundai has improved the structure strength of the 9A series cabs with stronger but slimmer tubing for optimum safety. Low stress, high strength steel forms a more durable upper and lower frame. Structural integrity of these three models was tested by way of FEM (finite elements method) analysis and long term durability tests. An optional ROPS (roll over protective structure) cab can be equipped to further enhance operator safety.
The enlarged cabs on the R140/180/210W-9A models provide added visibility. The newly designed cabs were conceived for more space, enhanced operator comfort and a wider field view. 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 put the operator in the perfect position to work safety and securely.
In addition to enhanced safety and visibility, operators will enjoy being able to fully customize the cab of the R140/180/210W-9A excavators to best fit their needs. Operators can easily adjust the seat, console and armrest settings to the desired comfort level. Hyundai has integrated the seat with the console to reduce operator fatigue and adjustable air suspension comes standard. New joystick consoles are adjustable in height by pushing a single button.
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 for optimum air temperature, an advanced audio system with USB player, AM/FM stereo, and MP3 capabilities. A smart key system is an optional add on feature that allows the operator to start the ignition with the push of a button.
The R140/180/210W-9A excavators come standard with a newly designed 7 in., 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.
Maintenance on the R140/180/210W-9A excavators is easy with ground-line access to filters, lube fittings, fuses, machine computer components and wide open compartments. 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 R140/180/210W-9A models 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.
