STABILITY CONTROL METHOD, DEVICE AND SYSTEM FOR PUMPING TRUCK AND PUMPING TRUCK HAVING THE SYSTEM

摘要

Disclosed is a stability control method for pumping trucks. The method includes obtaining a natural frequency of the pumping truck; and changing the displacement of a piston in a pumping oil cylinder of the pump truck so as to make the pumping frequency of the pumping truck unequal to the natural frequency. Also disclosed are a stability control device and system for pumping trucks and a pumping truck having the system. By means of adjusting the displacement of the piston in the pumping oil cylinder to change the pumping frequency so as to avoid resonance, it is not required to add additional excitation sources to the current concrete pumping truck, resulting in low cost, the capability to be transplanted quickly onto the existing concrete pumping trucks, good universality and convenience in use.
