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 can be moved manually by chain drive. This research aimed to design several variations in the main structure of jib crane using I beam 300 for the industry. Firstly, the design concept was made by varying the main beam of the I300. then calculated analytically. After that 2D and 3D images were made with 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 2 tonf, 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 stress that occurred according to Von Mises. Based on the simulation results, the best design is the JC-3 variant. Variant JC-3 simulation results show that the safety factor closed to the optimum point.
