Product Description
Engineered with precision hydraulics and proven ISUZU power, this 2016 Kobelco SK70 delivers reliable performance across demanding excavation projects. The 7-ton machine features a double variable displacement axial piston pump system operating at 29.4 Mpa working pressure, ensuring precise control and responsive digging力. At its core sits an ISUZU AU4LE2X engine generating 41kW at 2200 rpm, paired with a water-cooled 2.179L displacement system for optimal thermal management during extended operation cycles.
Operational capabilities include:
- Maximum digging reach of 6460mm with 4160mm depth capacity
- 5830mm boom configuration for versatile working envelope
- Compact footprint: 1760mm minimum front turning radius, 1290mm rear swing
- Dual travel speeds (2.8/5.3 km/h) for site flexibility
- 120L fuel capacity supporting full-shift productivity
- Axial piston rotary motor delivering 11.5 rpm swing speed
Currently located in Heze, Shandong, this joint-venture manufactured excavator combines Japanese engineering standards with practical operational economics for contractors requiring dependable 7-ton class performance.
