Product Description
Engineered with Kobelco's proven hydraulic architecture, this 2019 SK200 delivers exceptional digging performance through its dual variable displacement axial piston pump system and 34.3 MPa main overflow pressure (37.8 MPa supercharged). Powered by a Mitsubishi 6D34-TLU2D engine generating 110 kW at 2000 rpm, the water-cooled, turbocharged six-cylinder unit with built-in intercooling provides consistent output across demanding jobsites. Standard bucket digging force reaches 143 kN, escalating to 157 kN under supercharged conditions, while rod digging force peaks at 107 kN when boosted.
Operating at 20 tons working weight with 0.8 m³ bucket capacity, this joint venture-manufactured excavator maintains superior stability through optimized ground pressure (45/35 kPa depending on track configuration). Dual-speed travel capability (4.0/6.0 km/h) and 70% climbing ability ensure versatility across terrain. Currently located in Hangzhou, Zhejiang, this machine represents Kobelco's commitment to hydraulic efficiency and mechanical durability in the 20-ton excavator segment.
