: Hook is a component which will plays a vital role in many Industries like Manufacturing, Aeronautical, marine, Transport and constructions industries. The aim of Crank hook is to lifting and transferring heavy loads when loading and unloading. At the time of lifting loads hook will subjected to Stress and strain concentration and undergoes deformation. When the continuous loading and unloading the crank hook gets deformation and which will cause failure. At the time of designing crank hook mainly focused on the material, dimension and cross section. From the above mentioned three factors this project focused on the selection of material and optimization of material. Generally the crank hook was designed by different cross sections like Trapezoidal, Rectangular, Square, Circular and Triangular. Hook was manufactured by using Forged steel, and structural steel. But in this project we introducing some alloy steel materials like Wrought iron alloy and Mangalloy for choosing better material. According to curved beam theory trapezoidal cross section is best among the other cross sections for designing the crane hook. Initially the bed diameter of hook is taken from the Winkler-bach's formulae of curved beam theory. Then remaining Specifications (Parameters) considered approximate values for safe design of hook at the load of 600KN. In this project hook model is compared with different materials and optimization of material which is done by using NX NASTRAN software. Hook model design in Uni-graphics and Analysis of stress and deformation is done by using NASTRAN by applying load 600KN on Crane hook.
