control unit and the hydraulic system. A

controller area network system facilitates

a constant flow of information between

the engine and hydraulic system, ensuring

power is delivered exactly as it is needed.

This hydraulic system enables indepen-

dent or combined operations. Two travel

speeds offer either increased torque or

high speed tracking and an auto decel-

eration system and cross sensing pump

ensure fuel savings.

Two variable displacement axial piston pumps

have maximum flow capacity of 2 x 206,5 l/

min to reduce cycle times, while a high ca-

pacity gear pump, with a maximum flow of 2 x

28,5 l/min, improves pilot line efficiency.

The choice between standard and power

operating modes optimises performance

in all conditions, including harsh environ-

ments. Standard mode uses 85 % engine

power for general work and power mode

uses 100% engine power for heavy tasks.

The conveniently situated multi-function

colour LCD monitor panel has standard fea-

tures for simple control and efficient opera-

tion. These controls include mode selection,

precise flow rate regulation, auto deceler-

ation and display selection. Maintenance

and oil change intervals can be displayed,

a self-diagnosis function allows technical

problems to be quickly resolved and an

operational memory provides a graphic dis-

play of the machine’s status.

Levelling operations, movement of lifted

loads and tricky manoeuvres are all con-

trolled easily and precisely with control le-

vers. Buttons integrated on the levers are

used to operate additional equipment, like

grabs, crushers and grippers.

Ultimately an excavator’s work rate depends

on the performance of the operator. For this

reason, Doosan’s new DX225LCA machines

have been designed with the latest ergo-

nomics which enhance efficient operation,

improve safety and offer greater comfort.

New features include a spacious, all weath-

er sound-suppressed cab with a clear all

round view, effective air conditioning and

an adjustable seat, with an optional air sus-

pension system to reduce vibrations. For

improved safety, there are large handrails

and a wide step with anti-slip plates, right

and left rear view mirrors, a travel alarm

and safety glass.

This series has been designed for easy

maintenance and reduced downtime. A PC

monitoring function enables connection to

the e-POS system. Various parameters can

be checked during maintenance, including

pump pressure, engine rotation and engine

speed. This information can be stored and

printed for analysis.

Easy access to all components, including

the engine oil filter, radiators and grease

inlets, enables quick maintenance proce-

dures and prevents contamination to the

surrounding environment.

The engine oil filter offers a high level of

filtration, allowing an extended interval of

500 hours before changes. A highly efficient

water separator protects the engine by re-

moving most of the moisture from the fuel.

The arm to bucket pivot features a rolled

bushing with fine grooves, only requiring

greasing every 50 hours. Wear plates on

the inside and outside of the bucket lugs

increase disc service life.

Doosan earthmoving equipment – which

encompasses track, wheel and mini exca-

vators, articulated dump trucks (ADT’s), as

well as wheel loaders and various attach-

ments – has been designed to cope effi-

ciently and safely in Africa’s harsh operat-

ing conditions.

The company offers a national technical

advisory, maintenance and support ser-

vice through its branches in Johannesburg,

Durban and Wolmaransstad and dealers in

East London, Port Elizabeth, Cape Town,

Middelburg, Kimberley, Rustenburg and

Bloemfontein.
