Concrete pump truck

Concrete pump truck is the use of pressure to convey concrete along the pipeline continuous machinery. Consists of pump body and delivery pipe. According to the structure is divided into piston type, squeeze type, hydraulic diaphragm type. Pump body mounted on the chassis of the car, and then equipped with telescopic or inflatable fabric rod, to form a pump.

Concrete pump trucks are reconstructed from the chassis of a truck. They are equipped with kinematic and power transmissions, pumping and mixing devices, fabricating devices, and other assistive devices. The power of the concrete pump truck transmits the power of the engine to the hydraulic pump group or the rear axle through the power transfer case, and the hydraulic pump pushes the piston to drive the concrete pump to work. Then use the pump truck cloth rods and pipes, concrete will be transported to a certain height and distance.

Concrete pump electric control system control methods are mainly five kinds of mechanical, hydraulic, electromechanical electrical control, programmable logic controller, logic control. Concrete pump truck in addition to installing electrical control system to complete the control tasks, but also install a manual control system, which is also part of the control system. If the use of mechanical manipulation, generally have rod-type control mechanism and flexible shaft control mechanism in two ways. If you compare the two is not difficult to find that the flexible shaft control mechanism has more advantages, such as flexible layout, high transmission efficiency, less transition joints and the free travel is small, convenient travel adjustment, so the concrete pump truck operating system Mainly choose the flexible shaft control mechanism.
