Stress Analysis of Crane Hook with Different Cross Section Using Finite Element Method

Crane hook is a mechanical component used for material handing or transfer, observes stresses, induced when different kinds of load applied. From the safety point of view the crane hook damaged must be prevented due to crack fracture developed caused mainly at stress concentration areas. Stress on crane hook depends upon various geometric variables as well as material properties. In this analysis the material properties of hook kept constant throughout the analysis and stress is to be reduced by varying different geometric parameters. After optimizing the cross section of crane hook the approach turned towards the material saving during manufacturing of crane hook. For material saving the maximum stress region is to be identified by using FEM analysis and then material is removed by considering the maximum bending stress at failure point.
