The invention discloses a safety detection method for lifting amplitude variation and rotary motion of a tower crane. The method comprises the steps that when the tower crane is in a power-on operation state, a black box board detects a mechanical limiting state and an electronic limiting state of the tower crane once every 80 ms-120 ms; the operation states of a lifting motor, a rotary motor and an amplitude variation motor in the tower crane are regulated and controlled according to the mechanical limiting state and the electronic limiting state; a detection system comprises the black box board, a lifting mechanical limiter, a travel switch, a distance sensor, a weighing sensor, a torque sensor and a data input module; the data input module is electrically connected with the black box board and is used for inputting calibrated data; the lifting mechanical limiter, the travel switch, the distance sensor, the weighing sensor and the torque sensor are all electrically connected with the black box board and are used for data interaction; and the black box board is electrically connected with a driving module, and the driving module is electrically connected with the lifting motor, the rotary motor and the amplitude variation motor. The method has the advantage of being high in safety.
