Product Description
Built for immediate deployment, this 2017 Kobelco SK70 delivers reliable 7-ton performance across demanding jobsites. Powered by an ISUZU AU4LE2X engine generating 41kW at 2200rpm, this compact excavator combines precision hydraulics with proven mechanical durability. The water-cooled 4-cylinder engine and double variable displacement axial piston pump system ensure consistent power delivery during extended operation cycles.
Operational capabilities include:
- Maximum digging depth of 4160mm for foundation and utility work
- 6460mm maximum digging radius covering substantial work areas
- 5830mm boom length providing versatile reach for grading and material handling
- Compact 2630mm transport height enabling easy site-to-site mobility
- Dual travel speeds (2.8/5.3 km/h) optimizing productivity and repositioning
Hydraulic systems operate at 29.4MPa working pressure with 120L capacity, supporting continuous digging, loading, and grading tasks. Currently located in Luzhou, Sichuan, this machine arrives site-ready with complete fluid capacities and backhoe configuration. Ideal for contractors requiring dependable excavation performance in confined spaces and general constructi
