description The invention provides a hydraulic excavator rotary brake control method, device, controller and a storage medium, and relates to the technical field of hydraulic excavators. The hydraulic excavator rotary brake control method comprises the following steps that a main pump control parameter and a main valve control parameter, corresponding to a deceleration time point, of the hydraulic excavator and the deceleration time point in a required rotation duration are determined according to the required rotation duration obtained in advance and a preset deceleration rule; and when the operation time of rotation operation reaches the deceleration time point, a main pump is controlled to reduce the displacement and a main valve is controlled to reduce the opening degree according to the main pumpcontrol parameter and the main valve control parameter, so that the brake deceleration corresponding to a deceleration control parameter meets the deceleration rule. The rotation speed is reduced before rotation is finished.
