Product Description
Engineered with Kobelco's proven hydraulic architecture, this 2016 SK200 delivers consistent 20-ton performance through a dual variable displacement axial piston pump system operating at 34.3 MPa (37.8 MPa in supercharged mode). Power comes from the Mitsubishi 6D34-TLU2D engine—a water-cooled, turbocharged six-cylinder unit rated at 110 kW at 2000 rpm, featuring built-in intercooling for sustained output in demanding conditions.
Digging force reaches 143 kN at the bucket (157 kN supercharged) and 97.1 kN at the rod (107 kN supercharged), backed by a robust 0.8 m³ backhoe bucket. The machine maintains 70% gradeability and operates across two travel speeds—4.0 km/h and 6.0 km/h—with selectable 600 mm or 800 mm track plates to optimize ground pressure between 35-45 kPa.
Currently located in Changzhou, Jiangsu, this joint-venture manufactured excavator represents Kobelco's commitment to hydraulic efficiency and structural integrity. The 340-liter fuel tank supports extended operation cycles, while the 11 rpm swing speed ensures productive cycle times across infrastructure and earthmoving applications.
