Product Description
Engineered with precision in Yantai, this 21-ton excavator delivers exceptional performance through its Doosan DB58T-1 engine, generating 147kW at 2000 rpm. The DH215-7 series represents joint-venture manufacturing excellence, combining robust hydraulics with proven reliability for demanding excavation projects.
Hydraulic power defines this machine's capability. Bucket digging force reaches 144.1kN, while the rod delivers 104.9kN of breakout force. With a 0.86m³ bucket capacity and maximum digging depth of 6,660mm, productivity remains consistent across varied applications. The 9,970mm maximum reach and 6,810mm dump height provide superior loading efficiency.
Operating specifications include:
- Working weight: 20,600kg with optimal 52kPa ground pressure
- Multiple arm configurations: 2,400/2,900/3,500mm options
- Travel speed: 3.1-5.4 km/h for efficient site mobility
- 350L fuel capacity for extended operation
- Compact 2,750mm tail swing radius for confined spaces
Currently located in Lishui, Zhejiang Province, this air-cooled machine maintains the technical standards expected from Doosan's proven seventh-generation platform.
