Used/second hand Zoomlion Benz 47m 2012 year high pumping efficiency concrete pump truck

A concrete pump truck is a mechanical device that uses pressure to continuously transport concrete along a pipeline, consisting of a pump body and a delivery pipe. The concrete pump truck transmits the power of the engine to the hydraulic pump group or rear axle through a power transfer box. The hydraulic pump pushes the piston to drive the concrete pump to work, and uses the distribution rods and delivery pipes on the pump truck to transport the concrete to a certain height and distance.
