Product Description
【 Premium Recommendation 】 A second-hand Kobelco SK75 excavator from 2015, now priced at 60,000 yuan, offers an extremely high cost performance. This device has withstood the test of time and has a moderate cumulative working time, ensuring that it maintains good performance while also having a relatively long remaining service life. In terms of power, this machine is equipped with a high-performance in-line four-cylinder water-cooled turbocharged engine (the specific model is not provided, but it is estimated based on the same series of models), with an estimated power of about 40 to 50 kilowatts, which can meet the daily construction needs while ensuring fuel economy. The powerful output combined with the advanced electronic control system makes the operation more stable and efficient. Whether it is excavation or loading work, it can be handled with ease. In terms of the hydraulic system, a combination of highly efficient variable piston pumps and high-torque hydraulic motors is adopted, ensuring that the entire machine operates sensitively and responds promptly. Even in complex and ever-changing working environments, it can demonstrate outstanding operational flexibility and stability, making it particularly suitable for the rapid
