Analysis and Design of Crane Hooks Made of Various Materials

Abstract

- Crane hook is significant component used for lifting the load with the help of chain or wire ropes. Crane hooks are 
highly liable components and are always subjected to bending stresses which leads to the failure of crane hook. Failure of a crane 
hook mainly depends on three major factors i.e. dimension, material, overload. To minimize the failure of crane hook, the stress 
occurs edinit must be studied. Structural failure of the crane hook may happen as a crane hook is subjected to continuous loading 
and unloading. In this paper the design of the hook is done by analytical method for the different materials like high strength low 
alloy steel and Structural Steel. CATIA software is used for modeling the crane hook and ANSYS software used to find out the 
stresses induced in it. This result helps us for determining of stress in existing model. By predicting the stress concentration area, 
the hook working life increase and reduce the failure stress.
