Product Description
Engineered for precision and control, this 2012 Doosan DH215-7 delivers exceptional operator experience across demanding jobsites. Built at Doosan's Yantai facility, this 21-ton excavator combines responsive hydraulics with superior cabin ergonomics, ensuring fatigue-free operation during extended shifts. Powered by a Doosan DB58T1 engine generating 147 kW at 2000 rpm, it provides consistent performance while maintaining fuel efficiency through its 350-liter tank.
Operators benefit from excellent all-around visibility and intuitive controls that maximize productivity. The spacious cab sits at 3100mm height with 480mm ground clearance, offering commanding sightlines to the 9970mm maximum digging radius. Hydraulic responsiveness shines through 136.2 kN bucket digging force and 100 kN arm digging force, enabling precise material handling in confined spaces.
- 0.86 m³ bucket capacity with multiple arm configurations (2400/2900/3500mm)
- Stable 2750mm rear swing radius minimizes repositioning
- 12.1 rpm rotation speed for smooth, controlled movements
- 600mm track plates ensure solid ground contact and stability
- Currently located in Lishui, Zhejiang—ready for inspection
