The invention discloses a multi-mode amplitude control system of a crank arm type overhead working truck. A platform weighing sensor is arranged on a work platform and detects the load capacity of the work platform, a first arm length and angle sensor and a second arm length and angle sensor detect the amplitude variation angles and telescopic length of a first telescopic arm and a second telescopic arm, and a double-shaft tilt angle sensor is arranged on a rotary table and detects the tile angle of a truck body. Supporting leg stress detecting devices are used for detecting whether supporting legs are stressed or not. A controller calculates the actual amplitude of the first arm and the second arm according to signals detected by the first arm length and angle sensor, the second arm length and angle sensor, the platform weighing sensor, the double-shaft tilt angle sensor and the supporting leg stress detecting devices, the actual amplitude is compared with an amplitude limiting mode, an amplitude control curve is output, the corresponding amplitude variation and telescopic motion of the first arm and the second arm is controlled, multi-mode amplitude control is achieved, and the control system is flexible and variable, and meets different work conditions.
