Product Description
Engineered with precision in Yantai, this 2016 Doosan DH215-7 delivers 21-ton performance through proven hydraulic architecture and robust mechanical design. Powered by the Doosan DB58T1 engine generating 147 kW at 2000 rpm, this excavator combines reliable air-cooled efficiency with exceptional digging force—136.2 kN bucket force and 100 kN rod force ensure consistent productivity across demanding applications.
Operating specifications demonstrate superior working capability:
- Maximum digging reach of 9,970 mm with 6,660 mm depth penetration
- 0.86 m³ backhoe bucket capacity matched to 20,600 kg working weight
- 5,700 mm boom paired with selectable rod lengths (2,400/2,900/3,500 mm)
- 12.1 rpm rotation speed with 2,750 mm compact rear radius
- 350-liter fuel capacity supporting extended operational shifts
Currently located in Maoming, Guangdong, this joint-venture manufactured machine represents proven DH215-7 series engineering. Transport dimensions of 9,550 × 2,800 × 3,100 mm and 600 mm track plates provide stable ground pressure at 52 kPa. Ready for immediate deployment in construction, mining, or infrastructure projects requiring reliable mid-size excavation power.<
