Research On Safety Risk Assessment Of Tower Crane Construction

With the development of urbanization in China,the construction industry has rapidly The Tower crane plays an important role as indispensable lifting and transport equipment in the construction of elevators Tower crane is a special machine that is widely used in mechanical engineering is.With the extension of the project base,due to insufficient safety management in use,tower cranes cause more safety accidents that not only cause losses and economic losses,but also have a bad impact on society Therefore,the has a safety risk system in place for tower cranes,which assumes the construction safety risk of Turmdrehkran as a research object,an important theoretical significance and an applicable value for accident prevention and provides theoretical support for dynamic risk management and safety engineering decision making of tower cranes,In this contribution the development process and the management of the tower crane in Germany and abroad as well as the research situation of the safety management for tower cranes discussed.On The main research content of this document is determined on the basis of a comparative analysis of the related research results.Reading a large number of documents,the design characteristics of tower cranes are clarified,the safety accidents of tower cranes are analysed in the last ten years,clarifies the reasons for the safety risks of tower cranes and classifies the risk factors in May 5 by the error analysis method;and optimized.In Channel construction project based on human factors,mechanical equipment factors,management factors and environmental factors;the rating index system is established and the risk level of the rating index system is determined.Secondly,because of the establishment of a safety index system for tower cranes,combined with AHP and the entropy weight method,it leads to a deviation of the scientific weight determination and to appropriate evaluation results.Finally,the case study examines the applicability of the assessment model.ft.As For example,for the second stage of the Lianzhu residential area,the weight of the safety risk is determined by a combination weight method,and the safety level of the tower crane construction is calculated according to Fuzzy Factor method and the calculation results are analysed.
