The DX1000LC-7 is primarily intended to serve customers in quarrying and mining applications, removing overburden and loading large amounts of material into articulated dump trucks or rigid frame trucks.
Driven by the most powerful engine in the 100-tonne class, the DX1000LC-7 also has the highest hydraulic flow for this size of machine, which the manufacturer says provides best-in-class performance, higher productivity, lower fuel consumption and smoother controls.
The DX1000LC-7 has a new and spacious operator cab, equipped with ergonomic controls and instrumentation. Emphasis has been placed on keeping noise to a minimum through enhanced sealing of the engine compartment and extensive use of sound-dampening materials. All components and assemblies are designed, built and tested to ensure durability. Multi-stage filters and features such as track guards and cylinder guards for the boom and arm, the auto grease system and greased and sealed track links are designed to provide superior reliability and a long service life. Doosan says the DX1000LC-7 is also easy to maintain, further reducing downtime to a minimum.
The DX1000LC-7 excavator is powered by the new stage V version of the well-proven Perkins 2806J diesel engine, providing a power output of 469 kW (629 HP), which Doosan says is more than any other machine in this class. The engine meets Stage V emission regulations by utilising 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.
