The invention belongs to the technical field of overhead working truck operation control, and particularly relates to an amplitude limiting system and an amplitude limiting method for an overhead working truck. A telescopic arm is sleeved with a basic arm, a telescopic oil cylinder is arranged between the basic arm and the telescopic arm, the basic arm is further hinged to a rotary table, an amplitude variation oil cylinder is arranged between the basic arm and the rotary table, and the amplitude limiting system comprises a tilt angle sensor arranged at the arm head of the basic arm; and an amplitude limiting strip is arranged on the outer surface of the telescopic arm, a proximity switch sensor used for detecting the amplitude limiting strip is arranged at the arm tail of the basic arm, and the proximity switch sensor and the tilt angle sensor are both in signal connection with the console. Through combined application of the tilt angle sensor, the proximity switch sensor, the amplitude limiting strip and the controller in the amplitude limiting system, a novel stability protection method is provided, the operation safety of the overhead working truck is improved, the safety of workers is guaranteed, and the risk of property loss is reduced.
