Traditional risk assessment method for elevator in use only focuses on objective factor, but many accidents in elevator are caused by subjective factors. This paper proposed an risk assessment method focusing on all the subjective and objective factors such as the design, manufacture, installation, maintenance, use, inspection elements, an weighted coefficient for considering the influence of different elements to the risk has been obtained by using the statistical experts opinions, then the risk level of the analyzed elevator can be obtained with the expert system, some suggestions are given according to the risk assessment results for improving the safety level of elevator in use. An example is given to illustrate how the proposed system is applied.
