Maximum pumping height of a 45m concrete pump truck

The maximum pumping height of a 45m concrete pump truck is generally over 40m, although different manufacturers offer varied figures. Generally the vertical pumping distance of a pump depends on the length of its pumping arm, the rear two pieces of which usually cooperate to pump concrete. The biggest pumping height of pump trucks in China proves to be 411m, realized in 2008 by a Zoomline truck with a power of 572kw.

Essentially the pumping height is up to the motor power of a concrete pump truck. The stone of the pumped concrete is mixed with different particle sizes and different ratios, that is, aggregate gradation. The combination of sand and stone in a certain ratio is the sand rate. A certain amount of cement, fly ash, mineral powder, water, etc. are added during mixing to ensure that the mixed concrete has good workability and fluidity. It ensures that there is enough mortar wrapped around each aggregate. Under the pressure of the concrete pump, the principle of liquid incompressibility is used to push the concrete pump to a high place.

Therefore, you can just attach soft tube to the pumping arm if necessary. According to the pumping pressure, the attenuation of the pumping pressure in the pipeline is 0.133 kPa per meter. A 90-degree elbow is equivalent to the resistance of a three-meter straight pipe, and a three-meter hose is equivalent to the resistance of a twenty-four-meter straight pipe. It is impossible to maintain the normal pumping pressure to be less than twelve. You can calculate how many meters of hoses can be added based on the motor power of your 45m concrete pump truck. Pay attention to the thickness of the pipe, the quality of the sealing ring, the gap of the cutting ring of the eye plate, etc.
