sites, production halls, assembly lines, storage areas, power stations and similar places. Their design features vary widely according to their major operational specifications such as: type of motion of the crane structure, weight and type of the load, location of the crane, geometric features, operating regimes and environmental conditions. A hook is a tool consisting of a length of material that contains a portion that is curved or indented, so that this portion can be used to hold another object. In a number of uses, one end of the hook is pointed. They are used to transfer the materials having heavy loads. Crane hooks are liable components subjected to failure due to stress in accumulation of heavy loads. Area of cross section, material and radius of crane hook are the design parameters for crane hook. Failure of a crane hook mainly depends on three major factors i.e. dimension, material, overload. The design of EOT crane hook has been carried out. At present work To study the stress pattern of crane hook in its loaded condition, a solid model of crane hook is prepared with the help of ANSYS software. Real time pattern of stress concentration in 3D model of crane hook is obtained., the material of the crane is modified to increase its working life and reduce the failure rates. The chrome steel and Aluminum Alloy are used in this project for analyzing the hook. The complete study is an initiative to establish a FEA procedure, static linear analysis is carry out and dynamic analysis to find the modes and corresponding natural frequency and estimation of life cycle validating using Goodman diagram , for the measurement of stresses. For reducing the failures of hooks the estimation of stresses, their magnitudes and possible locations are very important. From the stress analysis. Š 2017, IRJET

1.INTRODUCTION A square besides handle might be a procedure regarding no fewer than two pulleys for a rope or acquaintanceship hung the middle of them, commonly used to lift alternately drive principal weights. The pulleys compelling reason support assembled with packaging odds what's more a short timeframe later squares necessity help supported with those objective you stop putting forth on that one may be settled moreover you stop advertising on that particular case moves for the stack. Those rope is hung, alternately wind, through the pulleys ought further bolstering to furnish to mechanical immaculate position that enhances that to drive related for the rope. Cranes are present day machines that are basically used for materials advancements being developed goals, era halls, mechanical generation frameworks, stockpiling regions, control stations and near spots. Their plan features change by and large according to their major operational judgments, for instance, sort of development of the crane structure, weight and kind of the store, territory of the crane, geometric features, working organizations and common conditions. A hook is an instrument involving a length of material that contains a bit that is twisted or indented, with the objective that this part can be used to hold another dissent. In different uses, one end of the hook is pointed, with the objective that this end can cut another material, which is then held by the twisted or indented segment. In the organizations crane hooks are one of the indispensable portions. They are utilized to exchange the materials having substantial burdens. Crane hooks are at risk s ISO 9001:2008 Certified Journal
