The invention relates to an overhead working truck tipping prevention control method. The method is characterized in that the method includes the following steps that 1, pressure sensor data of four supporting legs are read and converted to counter-acting force; 2, when the counter-acting force sum of the four supporting legs is not equal to the whole truck weight, fault processing is conducted; 3, when an arm frame acts, the counter-acting force sums of all adjacent supporting legs are calculated; 4, when the counter-acting force sum of any two adjacent supporting legs is larger than or equal to the speed limiting alarm value, step 7 is executed; 5, the current action slows down and an alarm is given out; 6, when the counter-acting force sum of any two adjacent supporting legs is smaller than the action limiting value, emergency processing is conducted; 7, after the arm frame is drawn back in place, machine halt is conducted, or step 1 is executed. The speed limiting alarm value is a product of a speed reducing safety coefficient and the whole truck weight, and the action limiting value is a product of a stopping safety coefficient and the whole truck weight. According to the overhead working truck tipping prevention control method, through the concise and clear control method, the tipping risks that an overhead working truck tips over towards any side are directly determined, early warning is extracted and processing is conducted, and the control complexity is greatly lowered.
