CONTROL METHOD AND CONTROL DEVICE OF PUMP TRUCK SUPPORT LEGS, AND CONTROL METHOD OF PUMP TRUCK

The present application relates to the technical field of concrete pump trucks, and provides a method and a device for controlling an outrigger of a pump truck, and a method for controlling the pump truck. The method for controlling the outrigger of the pump truck of the present application includes: obtaining a first tilting angle of an entire pump truck after a boom is unfolded; and in a case that the first tilting angle is larger than or equal to a first preset value, obtaining a current error count, and controlling the outrigger to act based on the current error count. According to the method for controlling the pump truck provided by the present application, the outrigger is controlled to act by comparing the first tilting angle with the first preset value. Consequently, the outrigger may also act within a certain range to level the entire pump truck after a boom has been unfolded, and thus flexibility of construction is improved, and construction efficiency is also improved.
