DESIGN AND ANALYSIS OF CRANE HOOK WITH DIFFERENT MATERIALS

A crane hook is a device used for lifting up the loads by means of a crane. crane hooks with circular, triangular cross section, rectangular, trapezoidal are used commonly. The crane hook mostly subjected to failure due to accumulation of large amount of stresses. 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 occurred in it must be studied. In this paper the design of the hook is done by analytical method for the different materials like SAE-AISI 1040 and ASMT GRADE 60. SOLIDWORKS software is used for modelling 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.
