A visual warning method for a running track area of a bridge crane comprises a crane main beam running on guide rails at the two ends and at least one projection lamp fixed to the crane main beam, and warning belts and warning characters are carved on a light filtering film of the projection lamp. The projection lamps vertically project warning belts and warning characters to the ground below the bridge crane, the warning belts formed by projection of all the projection lamps define a visual warning area on the ground, the warning characters formed by projection of all the projection lamps are located in the visual warning area, and in the operation process of a crane main beam, the visual warning area is located in the visual warning area. And a visual warning area formed by projection of the projection lamp and warning characters synchronously move on the ground of the plant along with the main beam of the crane, so that visual warning of a running track area of the bridge crane is formed.
