Crane Hook Analysis for different Cross-Section using ANSYS

A lifting hook is a device for grabbing and lifting loads by means of a device such as a hoist or a crane. A lifting hook is usuallyequipped with a safety latch to prevent the disengagement of the lifting wire rope sling, chain or rope to which the load is attached. Crane hook is always subjected to failure due to the accumulation of a large amount of stress concentration which caneventually lead to its failure. To study the stress pattern of crane hook in its loaded condition, a solid model of crane hook isprepared with the help of Solid Works 19.0 software. The pattern of stress distribution in the 3D model of the crane hook isobtained using ANSYS 19.2 software. In this present work, the obtained stresses by using finite element analysis and the WinklerBatch method in different cross-sections are compared & to reduce the stress formed in sections by changing its designparameters (changing the mass of material in trapezoidal section). The stress concentration factors are used in strength anddurability evaluation of structure and machine elements. It is observed that stress is affected if the weight is increased
