Cranes are industrial machines that are mainly used for materials movements in construction sites, production halls, assembly lines, storage areas, power stations and similar places. 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 several 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. In this paper the design of the hook is done by analytical method and design is done for the different materials like forged steel and high tensile steel. After the analytical method design and modelling of hook is done in modelling software (SOLIDWORKS). The modelling is done using the design calculation from the modelling the analysis of hook is done in FEA software (ANSYS WORKBENCH). This result leads us to the determination of stress in existing model. By predicting the stress concentration area, the hook working life increase and reduce the failure stress.
