Description
【 Product Name 】 : 2012 Hyundai R215-7C second-hand excavator 【 Working Hours 】 : Since its commissioning in 2012, this Hyundai R215-7C excavator has accumulated a total working time of 4,800 hours. For a medium-sized excavator, this working duration indicates that it is in the golden period of mechanical performance, ensuring the maturity and stability of the equipment without reaching a state of excessive wear. 【 Power System 】 : It adopts the Cummins 6BTAA engine as the power core. This engine is renowned for its powerful output and excellent fuel economy. In daily operations, it can easily handle various complex working conditions of excavation tasks. Whether it is earthwork excavation or rock crushing, it can maintain efficient operation. Meanwhile, thanks to its advanced emission control system, this model complies with national environmental protection standards and reduces its impact on the environment. 【 Hydraulic System 】 : It is equipped with a closed load-sensing hydraulic system composed of a main pump and control valve group provided by Kawasaki Corporation of Japan. This design not only enhances the operational response speed of the entire machine but also significantly reduces energy consumption loss, making the oper
