      Seoul (A Duo Company) can now offer you the new 36-tonne Doosan crawler excavator. It is the first Stage V model to feature Doosan’s D-Ecopower technology, which is designed with higher productivity and lower fuel consumption per hour, as well as smoother controls.

      To meet Stage V engine emission regulations, the new DX350LC-7 excavator is powered by the latest generation Doosan DL08 diesel engine, providing 209kW of power at 1800 RPM. The DL08 engine exceeds Stage V regulations without using exhaust gas recirculation (EGR). It boosts the quantity of air available during combustion, increasing the temperature of the process and reducing the number of particulates produced, this is combined with after-treatment technology to ensure minimal emissions. As a result of this new technology, maintenance of the diesel particulate filter (DPF) has been greatly reduced, with no maintenance required until the machine has operated for 8000 hours.

      The D-Ecopower technology uses an electronic pressure-controlled pump within a closed centre hydraulic system. Depending on the mode selected it can achieve increases of up to 26% in productivity and up to 12% in fuel consumption improvements. A closed centred main control valve minimises pressure loss, while the electric pressure-controlled pump manages and optimises engine power more effectively.

      The D-Ecopower system uses nine sensors to detect the amount of hydraulic oil necessary to accomplish a specific task and meter the amount of oil required rather than continuously forcing a fixed amount of oil through the system, thereby improving efficiency.

      As well as higher performance and cost savings, the new DX350LC-7 Stage V crawler excavator is ergonomically designed to enhance operator comfort and uptime, with a focus on low fuel consumption, increased power, robustness and versatility. Improved feedback to the operator through the joystick results in improved machine control and less operator fatigue. The acceleration and deceleration of the excavator workgroup functions are smoother, allowing the operator to perform repetitive swinging and digging motions with less jolting.
