The concrete pump truck is a high-efficiency concrete conveying device that integrates the pumping mechanism of the concrete pump and the hydraulic folding-type cloth distributing machine and supporting mechanism for the cloth on the chassis of the automobile, and integrates the functions of driving, pumping and distributing. Concrete transportation during construction of rural cities, residential quarters, stadiums, overpasses, airports, etc. It mainly includes the following parts: the boom frame, the pump truck boom is a box-shaped structure, and is fully hydraulically driven. The boom frame is folded in the form of 30 meters, 33 meters is a four-section arm Z (folding type), and the 35-meter, 37-meter boom It is a five-section arm RZ integrated type. The conveying pipe △ conveying pipe includes a standard straight pipe portion and a bent pipe portion. They can be easily replaced. The standard duct clamp has both the shaft joint function. The elbow at the end of the boom acts as a brake (brake) for the falling concrete and reduces the friction of the end hose. Since the hose is made of steel wire, the suitable pressure must not exceed 85 bar. The leg △ leg is driven by the cylinder to be deployed and supported on the ground. It allows the pump to work with enough span to ensure the stability of the vehicle. Boom Control △ All boom movements are hydraulically driven. All boom cylinders are equipped with safety valves to protect against overload or hydraulic line breakage. △Konele Group pump truck is a hydraulic tank using the space inside the fixed turret as the boom system. Its hydraulic oil can meet the operation of multiple cylinders at the same time. △ It can be operated manually on the pump truck or by using a wireless (wired) remote control.
