The invention relates to the technical field of engineering machinery, and discloses a limiter resetting system, a tower crane and a limiter resetting method. The limiter reset system can generate and send out a one-key reset signal through the man-machine interaction device, and the control device responds to the one-key reset signal to control the adjusting module to drive the cam assembly to rotate in the reset direction and responds to an in-place signal sent out when the microswitch module is triggered by the cam assembly. The adjusting module is controlled to drive the cam assembly to rotate in the calibration direction; and when it is determined that the microswitch module is released from triggering, the adjusting module is controlled to stop driving, so that the cam assembly stops rotating, and resetting is completed. Therefore, automatic resetting of the stroke limiter is achieved, manual debugging of the limiter is not needed, the labor intensity of workers is reduced, and the working efficiency is improved. The working efficiency is improved when the device is applied to the tower crane, and the operation risk is greatly reduced.
