52m Sinotruk HOWO 8X4 371HP Concrete Pump Truck

52m SINOTRUK HOWO 8x4 371hp Concrete Pump Truck
The concrete pump truck can be divided into large concrete pump truck and small concrete pump truck according to the length of arm frame.
The concrete pump truck is modified on the chassis of the truck, which is fitted with a motion and power transmission, a pumping and stirring device, a cloth device and other auxiliary devices.
The driving force of the concrete pump truck transmits the power of the engine to the hydraulic pump group or the rear axle through the dynamic split box, and the hydraulic pump pushes the piston to drive the concrete pump. Then the concrete is transported to a certain height and distance by using the cloth rod and conveying pipe on the pump.
In addition to driving the pump truck, the engine of the concrete pump is also used to drive the pumping mechanism, the stirring mechanism and the cloth mechanism.
The power of each working device of the concrete pump truck originates from the automobile engine.
When the concrete pump truck works, the power of the automobile engine passes through the gearbox to the compartment, then passes through the transfer box to each hydraulic pump or the chassis rear axle.
When the driver issued a switch to the pump position of the instructions, pneumatic solenoid valve control on the transfer box on the cylinder to promote the fork, fork and then push the separation gear to switch to the pump position, while cutting the power to the rear axle, so that the car in the state of the vehicle. Conversely, switch to the driving position. Now the control of the pump is basically realized by the remote controller.
