Hook Design Loading by The Optimization Method With Weighted Factors Rating Method

This study aims for 2-ton lifting hooks designed to be the appropriate size for using. Both of the cost, the strength, the security and the aesthetics by using the optimal designed method together with the highest weight method. In this study is divided a methodology to design the hook into three-step processes. The first step is to create a lifting hook by ISO 7597: 2013 standard (Forged Steel Lifting Hooks with Latch, Grade 8) to be an initial lifting hook. Then analyzed the axial load of 2 tons by the finite element method. The second step is to analyze by the optimal design to design the lifting hook with the higher safety value by the weight of the lifting hook remains the same or difference. The third step is to analyze the results of the second step by deciding on proper lifting hooks by highest weight method for sizing of the lifting hook. The results of the analysis showed that lifting hook that has been designed by the method presented in this research can be able to reduce the production cost of the materials by 27.5 percents per piece with increasing the safety equal to 42.16 percents. It is good looking and can be easily produced by comparing with the initial lifting hooks.
