Introduction:
The series of boom concrete pumps mounted on truck which is produced through the cooperation with "SERMAC" in Italy adopted high quality components to ensure reliability and durability, such as Rexroth hydraulic pump and electric valve, Hava hydraulic distributing valve, ratio valve and safety valve in Germany. The hydraulic system is open circuit with total hydraulic controlled pump feeding and armed frame movement. It is of high reliability and durability for bad working environment. Its cooling system has high cooling efficiency, and will not allow the temperature in hot weather of the pump feeder to exceed 60C in summer. The new S valve pump feeding system has strong feeding capacity, and its lubricating system is reasonably designed. This pump car has three ways of control, control panel, lined remote controller, and remote controller. It is easy to operate, and is flexible, accurate, and steady in frame movement.
