This research addresses the limitations of conventional lifting hooks in structural steel fabrication by developing an optimized J-shaped hook design. A proposed method involved using Osborn’s checklist for ideation, Taguchi’s L₈ orthogonal array to create a minimum experiments plan, Finite Element Analysis (FEA) to test the design, and the Multi-Objective Optimization by Ratio Analysis (MOORA) method to select optimum criteria. The Analysis of Means (ANOM) identified the key parameters, including hook body height (165 mm) and end length (160 mm). When a load of 1150 kg was applied, the improved J-shaped hook had a safety factor of 3.5, which was higher than Thailand’s B.E.2564 standard, and the deflection was only 0.392 mm. These results were better than the L-shaped hook with a safety factor equal to 2.37 and deflection equal to 0.669 mm. The design enhances safety, reduces deflection, and utilizes scrap materials to promote sustainable, zero-waste manufacturing. This framework sets new benchmarks for lifting equipment, improving efficiency and reliability in steel fabrication processes.
