Used Doosan DH420LC-7 Excavator

Powerful: Equipped with a Scania DC13 diesel engine with an output of 257 kW (349 hp), it is the most powerful engine in its segment, providing ample power for the excavator, ensuring stable operation in a variety of complex working conditions.
Excellent Fuel Economy: Utilizing highly efficient DOC/DPF+SCR after-treatment technology, eliminating the need for exhaust gas recirculation, coupled with the next-generation Smart Power Control (SPC3) technology, the DX420LC-7 improves fuel efficiency by 3-10% compared to the previous DX420LC-5 model.
High Operating Efficiency: By combining the SPC3 system with the new Doosan Mottrol main control valve, the DX420LC-7 delivers excellent digging, swing, and traction forces, as well as lifting performance. In company testing, productivity increased by 2% compared to the DX420LC-5. Comfortable and Convenient Operation: The spacious cab features excellent ergonomics, a new, high-quality seat, and more standard features than any other machine on the market, including a new 8-inch color LCD display, an integrated stereo system, and keyless ignition. Furthermore, a standard 360-degree camera provides a complete view around the excavator, allowing the operator to overlook the area outside the machine, enhancing safety and convenience.
Easy Maintenance: The diesel particulate filter (DPF) requires significantly less maintenance, with automatic regeneration intervals extended sixfold (60 hours) and soot removal intervals at 6,000 hours. From the operator’s seat, the operator can also view the amount of soot accumulated in the filter and the success of regeneration on a display panel. Furthermore, the excavator is pre-installed with the DoosanCONNECT system, which facilitates monitoring of machine performance and safety, promoting preventive maintenance. Solid and durable structure: Taking the DH420LC-7 as an example, the machine weighs 41.2 tons and has a solid structure that can withstand high working pressure. It is suitable for harsh working environments such as large earthwork projects, water conservancy projects and mines.
