Concrete pump truck is a kind of machine that uses pressure to continuously transport concrete along the pipeline. It is composed of pump body and delivery pipe. According to the structure, it can be divided into piston type, extrusion type and water pressure diaphragm type. The pump body is installed on the chassis of the car, and then equipped with a retractable or flexible distributing rod to form the pump truck.
Concrete pump truck with HOWO is reformed on the truck chassis, which is equipped with motion and power transmission device, pumping and mixing device, distribution device and other auxiliary devices. The power of the concrete pump truck transmits the power of the engine to the hydraulic pump set or the rear axle through the power transfer box, and the hydraulic pump pushes the piston to drive the concrete pump to work. Then the concrete is transported to a certain height and distance by using the distributing rod and conveying pipe on the pump truck.
HOWO Concrete pump truck Operating system and performance :
The electric control system of concrete pump truck is mainly controlled by five kinds of mechanical, hydraulic, electromechanical electrical control, programmable controller and logic circuit. In addition to the installation of electrical control system to complete the control task, the concrete pump truck is also equipped with manual control system, which is also a part of the control system. If mechanical control is adopted, there are generally two ways: linkage control mechanism and flexible shaft control mechanism. If the two are compared, it is not difficult to find that the flexible shaft control mechanism has more advantages, such as flexible layout, high transmission efficiency, few transition joints and small empty stroke, convenient stroke adjustment, etc., so the concrete pump truck's control system is mainly to choose the flexible shaft control mechanism.

Concrete pump truck with HOWO's support safety precautions
1 the supporting ground must be level. Otherwise, it is necessary to make a horizontal bearing surface. Can't support on the hole.
2. The pump truck must be supported on a solid ground. If the maximum pressure of the support leg is greater than the allowable pressure on the ground, the support plate or auxiliary square timber must be used to increase the surface area of the support.
3 when the pump truck is supported near the pit and slope, sufficient safety distance shall be reserved
4 when supporting, ensure that the whole machine is in a horizontal state, and the maximum horizontal deflection angle before and after the whole machine is not more than 3 degrees.
5 when the outrigger is unfolded or retracted, the rotating range of the outrigger is a dangerous area, and people may be hurt by clamping within the range
6 when supporting, all outriggers must be extended and extended to the specified position (the outrigger is aligned with the arrow on the lug, and the front outrigger arm is aligned with the arrow extending the arm of the front outrigger). Otherwise, there is a risk of tipping over. Wait a moment, according to the needs of the customer will do the corresponding instructions.
