Doosan IIIB excavator improvements

24 Apr 13 Doosan is hoping for a bigger slice of the 14-16 tonne crawler excavator market with its new DX140LC-3 and DX160LC-3 models.

The new excavators meet Stage IIIB engine emission regulations through the use of exhaust gas recirculation (EGR) to reduce NOx and a diesel particulate filter (DPF) to cut particulate matter.

The engine has a displacement of 5890 cm³ and delivers 15% more power and 11% more torque than the previous Stage IIIA models.  Factory tests indicate a reduction of up to 17.5% in fuel consumption, depending on the operating mode selected and the work being undertaken, Doosan says.

Fuel efficiency is improved in part because of a new fan clutch with electrically controlled fan speed.  In addition, a new ECO gauge on the control panel helps the operator to lower fuel consumption by providing real time monitoring of fuel rate and actual engine-percent load.

Joystick controls have been improved, with proportional thumb wheel switches and integrated buttons added to provide proportional control of attachments.

Among the numerous other new features in the cab is a USB port to plug your iPod in.
