DX225LCA HYDRAULIC EXCAVATOR

INNOVATION FOR LASTING VALUE

The DX225LCA hydraulic excavator was designed to off er all the advantages of its predecessor, plus

even more value for the operator. That includes a safe and pleasant working environment with

improved ergonomics, more comfort and excellent all-round visibility.
The new generation DOOSAN engine is optimised and electronically controlled to boost your

production and maximise fuel effi ciency. By using high-performance materials combined with new

methods of structural stress analysis, we have improved overall reliability. This also leads to longer
component life and reduced costs. Meanwhile, maintenance is reduced, increasing the availability of
the machine and reducing running costs.

Ground-breaking performance

The DX225LCA was designed to maximise your profi ts by performing to top standards on every job.
Its powerful engine and e-EPOS control system combine for outstanding productivity and effi ciency.

DOOSAN DB58TIS ENGINE

The heart of the DX225LCA is its reliable 6-cylinder water-cooled
engine. In combination with the e-EPOS electronic control system,
it offers the ultimate in power delivery and fuel economy. As well as
lowering running costs, it keeps harmful emissions to a minimum.

EXCAVATOR CONTROL

e-EPOS system (Electronic Power Optimising System)

If the engine is the heart of the DX225LCA, the e-EPOS is its brain.
It provides a perfectly synchronised communication link between
the engine’s ECU (Electronic Control Unit) and the hydraulic system.
A CAN (Controller Area Network) system enables a constant flow
of information between the engine and hydraulic system, ensuring
power is delivered exactly as needed.

Simple and efficient

• The choice between Standard and Power operating modes
guarantees optimal performance in 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 allows technical problems to be resolved
quickly and efficiently.

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

• Maintenance and oil change intervals can be displayed.

Hydraulic pump

The main pump has a capacity of 2 x 206.5 l/min,
reducing cycle times, while a high capacity gear
pump improves pilot line efficiency.

Swing drive

Shocks during rotation are minimised while
generous torque is available to ensure rapid
cycles.

Travel mechanism

The internal structure of the travel mechanism
is simplified for enhanced durability and
smoother performance.

Excellent working conditions

Ultimately an excavator’s work rate depends on the performance of the person who controls it.
That’s why the new DX225LCA was designed around the operator, with ergonomics that are specially
developed to maximise effi ciency and safety.
The DX225LCA cab off ers plenty of space, a clear view all around, a comfortable seat and eff ective air
conditioning. Fatigue is minimised so it’s easy to keep on working, hour after hour.

Air conditioning

The high-performing, electronically controlled air conditioning system
features 5 different operating modes allowing the operator to adjust
the airflow to suit conditions.

Control panel

The control panel is clear, simple to read and positioned for easy use,
allowing you to work safely and confidently.

Air suspension seat (optional)

As well as being adjustable and offering lumbar support, the seat has
an air suspension system to reduce vibrations. A seat heating system is
incorporated for more comfortable winter work.

MP3/CD player (optional)

Easy audio

The audio button is positioned
within handy reach so that the
driver can easily turn the radio
on and off, select channels and
control the volume.

Precise control for more effi ciency

The DX225LCA features a range of technologies that deliver the most eff ective control over the
machine’s power as well as making maintenance easier. This increases both effi ciency and machine
durability, raising your productivity, lowering costs and making the DX225LCA an excellent investment.
