Doosan Construction
Equipment has launched
the DX210W-5, a new 21
tonne Stage IV compliant
wheeled excavator. As well
as meeting the latest Stage
IV emission regulations, the
DX210W-5 goes much further
and sets a new benchmark
for wheeled excavator
design worldwide.

This
achievement is marked by
a distinctive new machine
styling scheme that is common
to all new Stage IV
machines from Doosan.
The new DX210W-5 offers
enhanced comfort and controllability
together with
new features to boost fuel
efficiency, uptime and return
on investment, with a
focus on increased power,
robustness and agility.

CoreTMS Fleet Management
System as Standard
In common with all
Doosan Stage IV excavators
above 14 tonne, the
DX210W-5 is factory-installed
with the new CoreTMS
state-of-the-art wireless
fleet monitoring system.
Designed specifically for
the Doosan range, the
CoreTMS system is a new
tool providing comprehensive
information about
machine performance in a
dual mode (satellite, GSM).
Because the software in the
CoreTMS system has been
upgraded to communicate
directly with the EPOS
system on a Doosan excavator,
it is the only tool of
its type capable of providing
this level of information,
delivering insightful
and cost-saving data about
equipment to help customers
work more effectively.
Also available for retrofitting
in a kit form, the
CoreTMS system is supplied
with a free 3-year
subscription in new ‘W-5’
wheeled excavators and
customers are provided
with their own account so
that they can manage the
machines in their fleet using
the system.
Increased Power and
Fuel Efficiency
The new DX210W-5 excavator
is powered by the
well-proven 6-cylinder, turbocharged
Doosan DL06P
water-cooled diesel engine,
which is one of the most
reliable and fuel efficient
ever produced by Doosan,
providing an output
of 141.2 kW (189 HP) at
1900 rpm, a massive 17%
increase in engine power
over the previous generation
machine. The DL06P
engine offers convenience
and lower costs by meeting
Stage IV emission regulations
without the need for
a diesel particulate filter
(DPF), through the use of
cooled exhaust gas recirculation
(EGR) and selective
catalyst reduction (SCR) after-
treatment technologies.
As well as the DL06P
engine, new innovative
and exclusive features
have been introduced that
reduce fuel consumption
by an average of 10%.
Among these features is the
new ‘Trip Meter Setting’
screen which allows operators
to check fuel consumption
daily (or over a desired
period) directly from the
control panel and to save
even more fuel, there is a
special Doosan-developed
system, Smart Power Control
(SPC), which monitors
both engine and pump
power and limits unnecessary
outputs depending on
whether the work is light
or heavy. The SPC can be
used with all 4 work modes
(E, S, P, P+).
Further fuel efficiency
results from the electric fan
clutch on the DX210W-5
excavator which drives
the cooling fan at optimum
speed. Based on coolant,
hydraulic oil, cooled
charged air temperatures
and target engine speeds,
the fan speed is controlled
electrically – resulting in
much lower fan noise and
better fuel efficiency.
As well as the 17% increase
in engine power, the
DX210W-5 has 14% more
engine torque. The new
Posicon hydraulic system
also offers a 3% increase in
hydraulic capacity, which
translates into an 8% improvement
in the bucket
force and 6% more arm
force. The 900 kg weight
increase and the greater
machine width result in
front lifting capacities being
increased by 4 to 8%
(attachment down/up),
while the over the side
capacities have increased
by 12 to 15% (attachment
down/up).
Outstanding Comfort and
Controllability
The DX210W-5 utilises
the ‘CabSus’ cab suspension
system which reduces
vibration by 20% and complements
this with an impressive
2 dBA reduction in
external noise level and a
massive 4 dBA reduction in
cab noise, further increasing
safety and comfort for
the operator.
The ergonomic and
comfort features offered as
standard in the new cab are
among the best on the market
and include the world
exclusive Doosan jog shuttle
switch; four work and
four power modes; control
of pressure and flow of the
auxiliary lines directly from
the operator’s seat; and
joystick and pedal proportional
control with super
controllability via short and
low stroke joysticks and a
new system allowing usage
of the two-way lines either
from joystick or pedal.
The operator also has
the benefit of improved
side visibility, a new userfriendly
7 inch FT LCD colour
monitor control panel,
and fully automatic climate
control system, more storage
compartments for paperwork
and other items,
as well as an improved
layout with the most important
switches grouped
together within easy reach
on the right console. The
new pressurised cab incorporates
sealing, air filters
and increased air pressure
inside to prevent dust from
getting into the cab (ISO
10263-3).
A side-view camera is
available as an option and
the control panel allows
the views from both the
rear and side view cameras
to be combined on
the same screen, simply by
pressing a button on the
control panel. For more
safety when using the cameras,
a menu bar now stays
open so that the operator
can keep an eye out for
warning symbols and the
levels of key gauges. New
boom lights on the front
equipment more than double
the lighting available
and for better protection,
a guard has been added as
standard.
The auto-idling rpm on
the DX210W-5 automatically
increases from 800
rpm to 1100 rpm when the
temperature goes below 10
°C. This boosts the efficiency
of the heating inside
the cab.
Lower Total Cost of
Ownership
In the undercarriage,
the chassis frame has beenreinforced to reduce stress
and improve durability.
The outrigger frame has
also been strengthened by
moving to a box type assembly,
with an increase in
the thickness of most parts
for additional strength.
The dozer blade and HLink
have been reinforced
to increase rigidity and optimise
tightening between
the two structures. The
height of the dozer blade
has been increased along
with an improved shape to
facilitate pulling and mixing
of materials. The size
of the outrigger covers has
been reduced to lessen the
possibility of damage.
Made from cast steel,
the arm end boss and arm
link boss and side plates
have been combined to
increase durability. Piping
layouts have been redesigned
to avoid interferences
between hoses and
pipes, decreasing pressure
loss as a result. The twin
tyre rubber spacer has a
new symmetric design and
a new tight rim connection
ensures no bending and a
good connection to withstand
impacts from stones
and other materials.
To further maximise durability
and reduce noise,
the DX210W-3 is equipped
with EM (Enhanced Macrosurface)
bushings, which
are also much more effective
than regular bushings
when greased.
Air pre-cleaners are fitted
as standard on the
DX210W-5, to blow much
of the dust, dirt, insects,
rain and snow out of the
air intake, to ensure cleaner
air is sent to the engine
air filter. This extends air
cleaner servicing intervals,
enhancing uptime and
productivity. Doosan has
also added protection to
the inner cab air filter and
redesigned the cab air-conditioning
filters for easier
replacement.
To avoid permanent engine
damage, an acoustic
alarm has been added to
call the operator’s attention
to ‘water in fuel’. If
the operator ignores the
signal after several alerts,
the engine and pump are
automatically derated. In
addition, to make it easier
for operators to understand
the importance of warnings
and to communicate
the proper warning codes,
pop-up menus appear with
detailed information with
easier to identify warnings.
There is a larger bonnet
opening angle and height
for better visibility of the
components - the bonnet
opening angle has been increased
to 60° and the door
opening height is now 1040
mm. The battery capacity
has been increased to
2*150 AH (950 cca) which
provides strong cranking
performance in cold environments.
The alternator
has a capacity of 80 A as
standard. The battery is
located inside the storage
box, and the fuel pump
remains inside the pump
compartment.
The Engine Emergency
Stop Switch has been relocated
on the side of the
seat so that it is directly accessible
from ground level,
for faster access in case of
emergency. Star-shaped
anti-slip plates ensure that
the steps stay much cleaner
and more effective and to
meet new EU regulations,
safety bars are included as
standard.
