The invention discloses a pump truck stability control system, which comprises a detecting device and a controlling device, wherein the detecting device is used for detecting current pumping state parameters, boom posture parameters, landing leg posture parameters, pump truck body position state parameters and current numerical signals of external load parameters acting on a boom system of a pump truck, and the controlling device is used for receiving the current numerical signals of the above parameters, calculating the complete machine gravity center position of the concrete pump truck according to the parameters, and performing stability control for the pump truck according to the position of the complete machine gravity center in a pump truck stability area. The stability control system comprehensively takes pump truck own factors and external load influence factors into consideration, gravity center computational precision is high, and construction safety of the concrete pump truck is enhanced. In addition, the invention further provides a pump truck stability control method and a pump truck comprising the pump truck stability control system.

Pump truck stability control system, control method, and pump truck

A stability control system for an engineering machine and a control method are provided. The stability control system includes a detection device (), a control device () and an alarm device (). The detection device () detects the current center-of-gravity positions of each component of the engineering machine to obtain the center-of-gravity position signals of each component and transmits the center-of-gravity position signals to the control device (). The control device () receives the center-of-gravity position signals from the detection device (), calculates the center-of-gravity position of the engineering machine according to a center-of-gravity calculation strategy, and compares it with a preset balance range. The control device () controls the alarm device () for warning when the center-of-gravity position of the engineering machine exceeds the balance range. The stability control system adopts a brand new method to control the stability of the engineering machine in working process, and has higher control precision. An engineering machine comprising the above stability control system is also provided.
