The Deflection of the Column-mounted Jib Crane with Tapered Boom by Finite Difference Method

Abstract

One of the most frequently utilized crane types in industrial applications is the column-mounted jib crane. There are many different designs according to different requirements about lifting height, span, payload capacity, drive options, etc. Within the efforts to optimize the structure's mass, heavy-duty jib cranes with high payload capacity and extended reach often have their boom tapered. Besides strength, deflection is the most considered design criteria, where the crane structure is subjected to the total payload capacity at the tip of the boom. The paper presents the application of the finite difference method (FDM) and MATLAB code for the deflection of the column-mounted jib crane with a tapered boom. Obtained results are very close to the results from the finite element method (FEM) model in Ansys.
