DESIGN AND ANALYSIS OF CRANE HOOK TRAPEZOIDAL CROSS-SECTION USING FINITE ELEMENT ANALYSIS

Abstract

A lifting hook is a device for grabbing and lifting loads by means of a device such as a hoist or crane. A lifting hook is usually equipped with a safety latch to prevent the disengagement of the lifting wire rope sling, chain or rope to which the load is attached. Crane hook are always subjected to failure due to accumulation of large amount of stress concentration which can eventually lead to its failure. To study the stress pattern of crane hook in its loaded condition, a solid model of crane hook is prepared with the help of Creo Parametric 2.0 (Computer Aided Three Dimensional Interactive Application) software. Pattern of stress distribution in 3D model of crane hook is obtained using ANSYS 15.0 software. In this present work, the obtained stresses by using finite element analysis and Winkler-Batch method in different cross-sections are compared & to reduce the stress formed in sections by changing its design parameters (changing the mass of material in trapezoidal section). The stress concentration factors are used in strength and durability evaluation of structure and machine element. It is observed that the stress is affected if the weight is increased
