Product Description
There is currently a second-hand Kobelco SK75 excavator produced in 2013, which can be used for approximately 6,000 to 8,000 hours and is priced at just over 60,000 yuan. This is a small excavator with outstanding performance and extremely high cost performance, especially suitable for urban construction and small-scale engineering operations. In terms of the power system, this device is equipped with the highly efficient and energy-saving Yanmar 4TNV98 engine, with a rated power of 40.5 kilowatts, ensuring stable and reliable power output under various complex working conditions. Its low fuel consumption and low emissions also make this excavator perform exceptionally well in terms of environmental protection. The hydraulic system adopts advanced negative flow control technology and is equipped with a high-quality variable piston pump and hydraulic motor combination, which can achieve precise and rapid operation response, while ensuring high efficiency and stability during long-term operation. In addition, through the optimized design of the heat sink layout, the overall heat dissipation capacity of the machine has been effectively enhanced, and the service life of key components has been prolonged. As a compact excavator, the Kobe
