Design and Analysis of Crane Hook with Trapezoidal Cross-Section: A Study on Static Structural and Modal Analysis

In material handling equipment, crane hooks are essential parts that must withstand varying loading conditions. The performance characteristics of crane hooks made of different materials are thoroughly examined in this work. Total deformation and equivalent stress under operating loads are evaluated using Finite Element Analysis (FEA). The research technique includes using industry-standard FEA software packages like ANSYS for finite element meshing and simulation after creating 3D models of crane hooks using SolidWorks Computer Aided Software (CAD) software. To model operational stresses, a variety of loading scenarios that closely resemble real-world circumstances are used, and material parameters like yield strength and modulus of elasticity are taken into account. Through systematic analysis and comparison, this study evaluates the total deformation and equivalent stress distributions across crane hooks with a trapezoidal cross-section with the material assigned AISI 1040, AISI 4140 and Stainless Steel (SS316). The hooks with different materials were loaded at loads of 20 kN, 35 kN and 50 kN to check the effect of load on each material. The influence of material properties and hook geometry on deformation and stress distribution is examined to determine the material better for the application of crane hooks. Also, modal analysis was conducted to determine deformation at a specific frequency. Analysis reveals insights into deformation and stress distribution, helping material selection and design optimisation of hook. Findings contribute to enhancing safety and efficiency in the design process of trapezoidal cross-sectional hooks. Major Findings: The primary results reveal that crane hooks featuring trapezoidal cross-sections demonstrate superior loadbearing capabilities and diminished stress concentration, thereby improving durability and operational safety when handling heavy loads.
