Product Description
Built for operators who demand precision and control, the 2020 Hyundai R215-7 is a 21-ton hydraulic excavator engineered to perform across demanding job sites. Powered by the Hyundai D6BT-C six-cylinder, four-stroke turbocharged direct injection engine delivering 110 kW at 1,950 RPM, this machine combines raw digging force with refined hydraulic response. With a bucket digging force of 123.3 kN and a maximum digging depth of 6,800 mm, it handles heavy earthmoving with consistent, reliable output.
