Excavator Control

New e-EPOS system (Electronic Power Optimizing System)

The brains of the hydraulic excavator, the e-EPOS, have been improved and now can electronically link to the engines ECU (Electronic Control Unit), 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.

DOOSAN Infracore is aware of the importance of protecting the envi­ronment. Ecology was uppermost in the minds of the research workers right from the start of the design of the new machines. The new challenge for the engineers is to combine the protection of nature with equipment performance and to this end DOOSAN has been investing heavily.

The new Doosan engine respects and protects the environment, limiting all types of toxic emissions.

The advantages of the new e-EPOS impacts at several levels.

Ease of operation and user-friendliness:

• The availability of a power mode and a normal operating mode guarantee maximum efficiency under all conditions. • Electronic control of fuel consumption optimizes efficiency. • 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.
