Design and Analysis of 50 Tonne Crane Hook for optimization

Hooks are employed in heavy industries to carry tonnes of loads safely. These hooks have a big role to play as far as the safety of the hoist loaded is concerned. With more and more industrialization the rate at which these hooks are forged are increasing. This work has been carried out on one of the major hoist hook carrying a larger load comparatively. So in present work the solid modeling and finite element analysis of crane hook has been done using Solidworks and ANSYS workbench. For analysis purpose virtual model of crane hook is prepared by picking data from design data book. Curved beam flexure formula is used for determination of stresses in crane hook analytically. Finite Element Analysis have been performed on trapezoidal cross sections. To investigate the static stress results, both finite element method and exact solution method are applied and compare the stress results obtained by finite element and exact solution methods. From the output of these analyses it is observed that results obtained are in close agreement with each other and maximum stress concentration occurs at inner most surfaces.
