Product Description
Engineered with precision in Chengdu, this 2014 Kobelco SK75 delivers 7-ton performance through proven Japanese hydraulic technology. At its core sits an ISUZU AU4LE2X engine generating 41kW at 2200rpm, paired with a double variable displacement axial piston pump system that maintains working pressure at 29.4 MPa for consistent digging force across all operations.
Hydraulic efficiency defines this machine. The traveling circuit operates at 27.5 MPa while the rotary system maintains 14.5 MPa through an axial piston motor, ensuring smooth simultaneous operations. With a 120-liter hydraulic reservoir and water-cooled 2.179L displacement engine, thermal management remains optimal during extended work cycles.
Dimensional capabilities include:
- Maximum digging reach: 6460mm with 4160mm depth capability
- Vertical excavation depth: 3450mm for trench applications
- Compact 1290mm rear turning radius for confined jobsites
- Transport height: 2630mm for standard trailer compatibility
- Dual travel speeds: 2.8/5.3 km/h
Currently located in Shaanxi, this joint-venture manufactured excavator represents Kobelco's commitment to hydraulic efficiency and operational reliability i
