Product Description
Engineered for demanding excavation work, the Doosan DH215-7 pairs a Doosan DB58T1 engine rated at 147 kW at 2,000 rpm with an air-cooled system and a 350-liter fuel tank — delivering consistent power output across extended operational cycles. Built under joint-venture manufacturing standards in Yantai, Shandong Province, this 21-ton machine reflects the precision engineering that defined the DH7 series as a benchmark in mid-size hydraulic excavators.
