Description
【 Hitachi 670 Pile Driver This second-hand Hitachi 670 pile driver is specially designed for efficient and stable pile driving operations and is suitable for various construction sites and infrastructure projects. Since its commissioning in 2015, this equipment has accumulated approximately 4,500 hours of working time. During this period, regular maintenance and upkeep have ensured its good operating condition. For a professional-grade construction machine, such a usage frequency means that it is in the best working cycle. In terms of the power system, a high-performance diesel engine is adopted as the core drive source, which not only provides strong power output but also takes into account fuel economy and environmental protection performance. In actual operation, it can respond quickly to the driver's instructions. Whether it is starting or accelerating, it is very smooth, ensuring construction efficiency while also reducing operating costs. The hydraulic system is a major highlight of this machine. It adopts an advanced closed-loop design, combined with high-precision proportional control valves, which makes the pressure loss of the entire system smaller and the response speed faster. This means that when performing complex and v
