Product Description
Engineered with precision hydraulics and proven ISUZU AU4LE2X power, this 2016 Kobelco SK70 delivers 41kW at 2200rpm through a water-cooled, 4-cylinder configuration displacing 2.179L. Advanced double variable displacement axial piston pumps drive a working hydraulic circuit rated at 29.4 MPa, ensuring consistent performance across demanding excavation tasks. The axial piston rotary motor operates at 14.5 MPa, providing smooth 11.5 rpm slew speeds for optimal cycle times.
Key technical specifications include:
- Maximum digging reach: 6460mm with 4160mm depth capability
- Vertical wall digging depth: 3450mm for precise trenching operations
- 5830mm boom length paired with 7390mm maximum excavation height
- Dual travel speeds (2.8/5.3 km/h) for versatile site mobility
- Compact 1290mm rear swing radius minimizes space requirements
- 120L fuel capacity supports extended operational periods
Currently located in Jiangxi, this joint venture-manufactured machine represents Kobelco's commitment to hydraulic efficiency and structural durability in the 7-ton excavator segment. Complete service fluid capacities documented for immediate deployment.
