【 Sumitomo 120A3 Second-hand Excavator 】 We are extremely honored to recommend to you this second-hand Sumitomo 120A3 excavator with outstanding performance and excellent condition. Since its commissioning, this equipment has accumulated a working time of only 5,000 hours, which is far shorter than the average service life of machines of the same model. Therefore, its overall condition is almost on par with that of a new car. Both the appearance and the internal mechanical structure have been meticulously maintained and serviced, ensuring long-term stable operational performance. This excavator is equipped with an original imported electronically controlled diesel engine as its power core. It not only starts quickly and runs smoothly and quietly, but more importantly, it has excellent fuel economy and can effectively reduce operating costs. It is also equipped with an advanced electronic control system that can automatically adjust the output power according to the actual load, achieving the goal of high efficiency and energy conservation. In terms of the hydraulic system, the Sumitomo 120A3 adopts a high-quality pump and valve combination and an optimized oil circuit layout, ensuring a powerful and precise action response speed.
