ECONOMICS

The Doosan excavator, a combination of four advanced
technologies, guarantees a significant reduction of maintenance
costs thanks to its exceptionally low rate of fuel consumption.

COMPACT & FAST

Doosan’s DX200A is 380 mm shorter than the DX225LCA in track
length, which makes the DX200A suitable for the small space
where LC equipment is too wide to enter.

Handling &

Comfort

Doosan products are designed for
convenience and safety. Doosan’s machine is
designed for comfortable, long-term operation
in tough areas. Doosan's goal of ensuring user
convenience can be seen even in the simplest
service work.
A driver should keep the peak condition to
produce a maximum workload. In particular, if
a driver has to work more than 10 hours a day,
the driver’s condition can affect a workload
significantly. Doosan equipment is designed
to be operated conveniently at driver’s wills,
so that the driver can keep the best condition.

e-EPOS

New e-EPOSTM system (Electronic Power Optimizing System).

The brains of the hydraulic excavator, the e-EPOSTM, have been
improved, through a CAN (Controller Area Network)
communication link, enabling a continuous exchange of
information between the engine and the hydraulic system.
These units are now perfectly synchronised.

The advantages of the new e-EPOS
Ease of operation and user-friendliness:

• The availability of a power mode and standard mode guarantee
maximum efficiency under all conditions.

• The automatic deceleration mode enables fuel saving.

• Regulation and precise control of the flow rate required by the
equipment are available as standard.

• A self-diagnosis function enables technical problems to be
resolved quickly and efficiently.

• An operational memory provides a graphic display of the status
of the machine.

• Maintenance and oil change intervals can be displayed.
