Product Description
Engineered with Doosan's proven DB58T1 engine delivering 147kW at 2000rpm, this 2020 DH215-7 excavator represents solid hydraulic performance in the 21-ton class. Operating weight of 20,600kg provides stable digging force—136.2kN bucket force and 100kN arm force—while maintaining 52kPa ground pressure for versatile terrain adaptability. Maximum digging reach extends to 9,970mm with 6,660mm depth capability, supported by a robust 5,700mm boom and selectable arm lengths (2,400/2,900/3,500mm) for job-specific configuration.
Built at Doosan's Yantai joint-venture facility, this model combines Korean engineering standards with practical field durability. The air-cooled system and 350L fuel capacity support extended operation cycles. With 12.1rpm swing speed and 3.1-5.4km/h travel range, productivity remains consistent across excavation, loading, and grading applications. Compact transport dimensions (9,550×2,800×3,100mm) and 2,750mm tail swing radius enable efficient site mobility.
Currently located in Jinhua, Zhejiang Province, this DH215-7 offers proven mechanical reliability for contractors requiring dependable performance in infrastructure and earthmoving projects.
