Abstract
Crane is an important equipment of national economic construction. Compared with the faulty crane, the crane with good performance has lower energy consumption and less pollution to the environment. In this paper, the analytic hierarchy process is used to evaluate the safety of portal crane, to help users find and deal with the existing problems of crane in time, and to play a positive role in the sustainable development of national economy.
Highlights
Accidents occur frequently due to the unsafe factors of the equipment itself, which brings losses to the national economy and ecological environment
In this paper, according to the requirements of establishing safety evaluation system, the safety evaluation system of portal crane is constructed by using analytic hierarchy process
Analytic hierarchy process (AHP) mainly constructs judgment matrix to judge the relative importance of each factor in each level, and introduces appropriate scale to express it by numerical value
Summary
Quickness, flexibility and high efficiency to production. Accidents occur frequently due to the unsafe factors of the equipment itself, which brings losses to the national economy and ecological environment. In order to ensure the safe operation of the equipment, in addition to routine maintenance and maintenance, safety evaluation in the process of equipment use is an essential work [1]. We should consider the comprehensive performance of the equipment, and consider the factors of structural safety, so as not to be forced to scrap in the service life of the equipment, so as to avoid economic waste. If the cost of the equipment is over considered and the equipment with potential safety hazards is put into use, it will cause accidents and increase energy consumption. Scientific and reasonable safety evaluation is very necessary
