Design and strength analysis of the end carriage beam for the single girder bridge crane of a 500 kg load capacity

Abstract

Overhead cranes are used in production halls, industrial buildings, transshipment yards, automobile factories, as well as in agricultural warehouses. The end carriage is an essential part of any overhead crane. Special attention is focused on the end carriage beam, which is a fundamental component of the end carriage in terms of load and strength. The introductory part of the paper aims to introduce the crane issues, particularly with respect to bridge cranes. The paper attends to the design of the end carriage beam for a single girder bridge crane with a 500 kg load carrying capacity including a strength analysis of the proposed beam. On the basis of the input load data of the end carriage beam and dimensions of area on which the main girder is placed on the end carriage beam, the minimum section modulus in bending was determined through the Allowable Stress Method as a critical parameter for the selection of the end carriage beam. The calculated value of the minimum section modulus in bending is 1416.18 mm3, based on which the U4O beam profile of S235 JR material was selected. One of the objectives is to create a 3D CAD model of the proposed end carriage beam and subsequently perform FEM analysis of the beam using Ansys engineering simulation software. The purpose of the analysis is to determine the maximum bending stress and maximum deflection of the end carriage beam. The results of the FEA analysis demonstrate that the proposed beam is satisfactory in terms of allowable stress and deflection. Moreover, the beam designed in this manner along with the numerical simulation results provides a precondition of its possible future production.
