Product Description
Engineered with precision hydraulics delivering 29.4 MPa working pressure, this 2021 Kobelco SK70 represents superior Japanese excavation technology. Built around a robust ISUZU AU4LE2X engine producing 41kW at 2200 RPM, this 7-ton machine combines proven reliability with exceptional performance capabilities.
Advanced double variable displacement axial piston pump systems ensure optimal power distribution across all functions. With a maximum digging depth of 4,160mm and reach extending to 6,460mm, operational versatility meets demanding jobsite requirements. Water-cooled 4-cylinder engine maintains consistent performance under heavy loads.
- Maximum excavation height: 7,390mm for superior reach
- Compact 1,760mm front turning radius enables tight-space operation
- 120L fuel capacity supports extended work cycles
- Axial piston rotary motor provides 11.5 RPM smooth rotation
Located in Guizhou Province, this SK70 demonstrates Kobelco's commitment to hydraulic innovation and mechanical excellence. Professional maintenance records available upon request.
