Product Description
Built for buyers who want solid excavation performance without paying new-equipment prices, this 2020 Kobelco SK75-8 offers a smart balance of output, durability, and capital efficiency. Located in Guangxi, China, this 7-ton class excavator delivers reliable jobsite capability with a 6,850 kg operating weight, 0.4 m³ backhoe bucket, and an ISUZU engine rated at 42 kW at 2200 rpm.
Its working range supports trenching, grading, and utility work with a maximum digging depth of 4,170 mm, digging radius of 6,460 mm, and unloading height of 5,330 mm. Strong breakout performance includes 52.7 kN bucket digging force and 39.4 kN arm digging force, backed by a variable displacement axial piston pump for steady hydraulic response.
For contractors comparing used versus new, this SK75-8 stands out as a cost-effective investment: modern performance, proven Kobelco engineering, and significantly lower upfront cost than a new machine.
Key specifications include water-cooled 4-cylinder diesel power, 70% gradeability, 140 L fuel tank, and transport dimensions of 6200 x 2320 x 2650 mm.
