Product Description
The modern 305-9T excavator, equipped with a breaker and a standard bucket, is a reliable assistant in your engineering projects. This equipment has been working for approximately 4,000 hours in total and is in good operating condition, capable of meeting various construction requirements. In terms of the power system, this machine is equipped with an efficient and reliable engine, which is expected to be of the Cummins 6BT series, with a rated power of approximately 120 horsepower, ensuring strong power output and stable performance. Whether facing hard rocks or soft soil, it can handle them with ease and provide abundant energy support. The hydraulic system adopts advanced load-sensitive control technology and may include key components such as variable piston pumps and high-performance hydraulic motors. This not only enhances operational efficiency but also effectively reduces energy consumption. In addition, its precise controllability and excellent response speed enable operators to complete complex tasks more freely. The main advantages of this second-hand excavator lie in its outstanding working ability and durability. After professional maintenance and care, the overall condition is good, with a clean appearance and no obvio
