Description
【 Premium Recommendation 】 Second-hand Komatsu PC70-8 excavator from 2013. This equipment not only has a well-maintained appearance but also performs exceptionally well. Since its release in 2013, the cumulative working hours have only been 4,500 hours, which is far lower than the average service life of similar models. This means that it still has a long service life waiting for its new owner to discover. In terms of power, this aircraft is equipped with an original imported Komatsu engine, which is renowned for its outstanding fuel economy and powerful output. It can maintain stable operation even under harsh working conditions, ensuring operational efficiency while reducing maintenance costs. In addition, the advanced electronic control system can automatically adjust the rotational speed according to the actual load, further enhancing the fuel utilization rate. The hydraulic system is a major highlight of this excavator. It adopts a closed central circuit design, combined with high-efficiency energy-saving pumps and precise control valves, making operation smoother and response faster. Whether it's digging hard soil or performing meticulous operations, it can handle them with ease, providing users with an unparalleled operational
