Design variations optimization of jib crane 24500 N using I beam 300

Abstract

Abstract A jib crane is a type of lifting equipment that is commonly attached to the walls of factory buildings to raise or lower a load. The lifting mechanism can rotate with a turning angle of 180 degrees. A trolley hoist can be moved manually by chain drive. This research aimed to optimize the design of several variations of the jib crane structure of load lifters that meet the criteria of optimizing safety factor. Firstly, the design concept was made by varying the main beam of the I Beam 300. Then calculated analytically. The 2D and 3D geometry were made in four variants of JC-1, JC-2, JC-3, and JC-4. The strength of the main beam structure and others was analyzed using FEM software. The load of the crane was 24500 N, a range radius of 3 meters, and a turning angle of 180 degrees. The best results were obtained by comparing the yield stress to the maximum stresses that occurred according to Von Mises. Based on the simulation results, the best design is the JC-4 variant. Variant JC-4 simulation results show that the safety factor closed to the optimum point.
