Comprehensive Evaluation for Safety Working Status of Hoisting Mechanism of Crawler Crane Based on 3-Scale AHP

Abstract:

To comprehensive evaluate the safety working status for hoisting mechanism of crawler crane based on fault analysis for hoisting mechanism of crawler crane, this paper builds a model of state comprehensive for hoisting mechanism of crawler crane and builds a fuzzy comprehensive set of safe working state for hoisting mechanism of crawler crane based on the 3-scale AHP(Analytic Hierarchy Process), then gets the weight of each index. With the help of the score of index graded by experts, safe working state comprehensive evaluation for hoisting mechanism can be gotten. The results of the engineering example shows that compared with 9-scale AHP, 3-scale AHP overcome the difference of subjective understanding, and save the inspection process of complex consistency, the method is concise and feasible, and the results reflect that it is same with the objective reality.
