The invention discloses a bridge crane anti-swing control method, a bridge crane device and a bridge crane, and relates to the technical field of motor control. The method comprises the following steps: calculating, obtaining and sending a swing frequency; correcting the acquired rotating speed preset signal based on the swing frequency to obtain a corrected rotating speed signal; and controlling the bridge crane based on the swing frequency and the corrected rotating speed signal. According to the bridge crane, the specific swinging frequency of the hoisting load can be effectively filtered out, interference between mechanical systems is effectively reduced, and hoisting load swinging generated by walking of a trolley mechanism of the bridge crane is restrained.
