What's New In Plant & Equipment

New Hyundai R140/180/210W-9A New Hyundai R140/180/210W-9A
Wheeled Excavators

Hyundai Construction Equipment Americas, Inc., has introduced three new wheeled excavator models, the R140W-9A, R180W-9A and the R210W-9A, to their 9A series product line.

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.

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 4/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.

Optimum Precision

To achieve optimum precision, Hyundai has redesigned the hydraulic system on each of these models to provide the operator with precision 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.

Boom-down flow regeneration and control valve technology are also 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 new 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 is also 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.       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.

An optional ROPS (Roll Over Protective Structure) cab can be equipped to further enhance operator safety.

The newly designed cabs were conceived for more space, enhanced operator comfort and a wider field view. Special attention has been given to a clear, open and convenient interior with plenty of visibility on the machine surroundings and the job at hand.

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.

The excavators come standard with a newly designed 7 inch, 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.

  • Maximum dump height: 6.62 m (21’ 9”) - with 4.6 m boom and 3 m arm length
