The Stage V compliant DX1000LC-7 also has the highest hydraulic flow for this size of machine, providing best-in-class performance, with higher productivity, lower fuel consumption and smoother controls. For the operator, there is a spacious cab where noise is reduced through enhanced sealing of the engine compartment and extensive use of sound-dampening materials.
The DX1000LC-7 excavator is powered by the new stage V version of the well-proven Perkins 2806J diesel engine, providing a high power output of 469kW, more than any other machine in this class. The engine meets Stage V emission regulations thanks to exhaust gas recirculation, selective catalyst reduction, diesel oxidation catalyst and diesel particulate filter (DPF) after-treatment technologies.
The DPF automatically regenerates every 25 hours and the excavator continues to work unaffected during this regeneration phase. The operator can check the status of the DPF via the display on the gauge panel in the cab.
The high output of the engine is combined with a Virtual Bleed Off (VBO) hydraulic system (D-ECOPOWER+) and controlled by electric manipulator (FEH). This provides a best-in-class hydraulic flow of 1569 l/min and a high system pressure of 360 bar, together contributing to the best performance in the 100-tonne market.
Doosan’s D-ECOPOWER+ FEH technology uses an electronic pressure-controlled pump within a closed centre hydraulic system to optimise productivity and fuel consumption, depending on the mode selected. A closed centered main control valve minimises pressure loss, while the electric pressure-controlled pump manages and optimises engine power more effectively.
The DX1000LC-7 is factory-installed with DoosanCONNECT wireless fleet monitoring system.
