Product Description
Engineered with precision in Chengdu, this 2014 Kobelco SK75 delivers 7-ton performance through a robust ISUZU AU4LE2X engine rated at 41kW/2200rpm. The water-cooled, 4-cylinder powerplant with 2.179L displacement provides reliable output for demanding excavation tasks. Hydraulic superiority defines this machine: a double variable displacement axial piston pump drives a 29.4 MPa working circuit, while dedicated systems maintain 27.5 MPa traveling pressure and 14.5 MPa rotary pressure for smooth, controlled operation.
Performance specifications demonstrate Kobelco's engineering commitment:
- Maximum digging reach: 6,460mm with 4,160mm depth capability
- Maximum digging height: 7,390mm for elevated work
- Compact footprint: 1,760mm minimum front turning radius, 1,290mm rear swing
- Dual-speed travel: 2.8/5.3 km/h for jobsite mobility
- Generous fluid capacities: 120L fuel tank, 72L hydraulic reservoir
Currently positioned in Fuzhou, Fujian, this joint-venture manufactured excavator combines Japanese engineering standards with practical operational efficiency. The backhoe configuration and axial piston motor rotary system ensure precise control across construction, utility,
