Abstract： Aiming at giving the accurate value of risk assessment and the level of portal slewing crane in risk management，a  comprehensive evaluation method is came up，which combines with the principle of the risk based inspection（RBI）and fuzzy analytical hierarchy process（FAHP）. Considered security system theory，indicator system was organized by factors of human，equipment，environment，management，as well as each stage of the cane's life. What is more，the FAHP was utilized to obtain the weights of indicators. And then，assessment was carried out by fuzzy comprehensive evaluation method and risk analysis matrix to determine the risk level of a case-crane. The results indicate that the proposed method is scientific and applicable，which is consistent with the report of the special inspection departments.
