Higher pressure and greater throughput will become the development trend of the china pump truck central pumping system in the future. In the initial design of the China boom concrete pump truck, the concrete delivery cylinder diameter was about 200 mm, and the output displacement was mostly concentrated below 100 cubic meters per hour. Since 2004, the concrete delivery cylinder with a cylinder diameter of 200 mm has been withdrawn from concrete pump truck products. At present, the most common conveying cylinder diameter in the market is 230 mm, and the output displacement is more than 120 cubic meters per hour.
 

As the boom of the boom-type china pump truck is getting higher and higher, the vehicle model is getting bigger and bigger, and the bore of its delivery cylinder is getting bigger and bigger. The largest bore in China has reached 260 mm, and the concrete output displacement is also larger. However, from the perspective of the overall configuration of the whole machine, due to the limitation of the height of the whole machine and the width of the frame, the application of concrete delivery cylinders with larger cylinder diameters is greatly restricted in the application of boom-type concrete pump truck. At the same time, the larger the bore of the concrete delivery cylinder, the greater the output displacement, and the greater the required chassis engine power. When the whole machine is working with a large displacement, the vibration of the boom will be greater. Therefore, if a large-bore boom concrete pump truck wants to replace the general-purpose cylinder with a bore of 230 mm, a lot of work has to be done and a long way to go.
 

Due to the higher and higher requirements of the project schedule, more and more projects require china pump truck with pumping displacement of 80~120 cubic meters per hour. Large displacement will become the development direction of boom-type concrete pump trucks in the future. Haomei Machinery has focused on the manufacture of concrete pumping equipment for more than 20 years. There are a wide variety of concrete equipment with high quality. The products are exported to Europe, Asia, Southeast Asia, South America, Africa, Oceania and other countries and regions.
