Product Description
Engineered with Doosan's proven DB58T1 turbocharged engine delivering 147 kW at 2000 rpm, this 21-ton excavator combines raw power with precision hydraulics. The DH215-7 features exceptional digging forces—136.2 kN bucket force and 100 kN arm force—designed for demanding earthmoving and trenching operations. Built at Doosan's Yantai facility in Shandong Province, this model represents joint-venture manufacturing standards with robust air-cooled systems and a 350L fuel capacity for extended runtime.
Operational versatility defines this machine: a 9970 mm maximum dig radius and 6660 mm dig depth handle large-scale excavation, while the compact 2750 mm tail swing radius enables confined-space work. The 0.86 m³ bucket capacity balances productivity with fuel efficiency across varied applications. Track configuration includes 600 mm shoes on a 2200 mm gauge, providing 52 kPa ground pressure for stable performance on soft terrain.
Currently located in Yunnan, this 2017 unit offers proven Doosan reliability with comprehensive technical specifications documented for transparent evaluation. Multiple arm configurations (2400/2900/3500 mm) allow project-specific customization.
