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 excava-
tors 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 operat-
ing 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 ex-
cavators with low emission, low noise, Cummins QSB6.7
Interim Tier 4/Stage IIIB engines. Electronically controlled
fuel injection and diagnostic capabilities add to the en-
gines’ 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.
To achieve optimum precision, Hyundai has rede-
signed the hydraulic system on each of these mod-
els to provide the operator with precision touch and
Improved pump flow control minimizes fuel consump-
tion and improved spool valves are engineered to provide
more precise flow to each function with less effort.
Boom-down flow regeneration and control valve tech-
nology 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 re-
duces 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 releas-
ing the ram cylinder according to the operat-
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
Low stress, high
strength steel forms a
more durable upper and

Structure) cab can be

The newly de-
signed cabs were con-
ceived for more space,
comfort and a wider
field view. Special attention has been given to a clear, open
and convenient interior with plenty of visibility on the ma-
chine surroundings and the job at hand.
Hyundai has integrated the seat with the console to re-
duce 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
The simplified design allows the operator to easily ad-
just 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 ma-
chine with the new password anti-theft system.
