Hoist Safety Risk Assessment Model Research

Considering the various factors which influenced the safety of hoist system, and the general objective which was the failure probability of hoist system, it established the safety risk assessment model for hoist system. Then it used the time-varying effect to forecast the failure probability and crash damage of hoist system. It constructed the evaluation index system, and used the AHP method, the fuzzy mathematics method and the method of expert advice on weight distribution at various levels. Based on the evaluation and analysis of Zhuzhuang reservoir projects on the gate crane, it proved that the safety risk assessment model for hoist system was scientific, safety and reliability.
