In response to the common fault forms of brake systems in bridge cranes and the problem of inability to quantify conclusions in inspection,a data-driven brake inspection and safety performance evaluation method is proposed according to the requirements of safety technical regulations.The process of brake inspection in daily inspection work is optimized,which provides a new basis for judging the inspection conclusion for the brake of the lifting machinery.Through the analysis of inspection examples,the rationality of the safety evaluation method is verified,proving that the method proposed in this article has practical significance in the inspection process.
