The invention discloses a tower crane slewing mechanism control method, equipment, a system and a storage medium, and relates to the technical field of electrical control. The method comprises the steps that the real-time big arm rotating speed of a tower crane big arm in a tower crane rotating mechanism, the real-time motor rotating speed of a rotating motor, the real-time rotating speed integral feedback of the real-time motor rotating speed and the real-time rotating speed integral calibration of the real-time motor rotating speed are obtained; according to the real-time big arm rotating speed, the real-time motor rotating speed, the real-time rotating speed integral feedback and the real-time rotating speed integral calibration, the driving torque output by the rotary motor is adjusted, and the adjusted driving torque is obtained; and controlling a rotary motor to drive a tower crane rotary mechanism to operate according to the adjusted post-driving torque. When the tower crane is shut down, the rotating speed of the motor and the rotating speed of the large arm can be controlled to synchronously reach zero speed without a turbine mechanism, the large arm of the tower crane is prevented from rebounding, the technical problems that in an existing tower crane slewing mechanism, rebounding of the large arm of the tower crane is restrained through an eddy current mechanism, and the cost is high are solved, and the control cost of the tower crane slewing mechanism is reduced.
