The objective is to analyze the structural integrity of an alternative lifting structure using the Finite Element Analysis (FEA) method implemented in SolidWorks software. Data were obtained through numerical simulations under three load scenarios to determine the maximum stress, maximum deformation, and buckling load factor (BLF) values. The results reveal that the maximum stress of 72.26 MPa remains well below the yield strength of SS400 and SS41 steels, while BLF > 1 indicates structural stability without buckling. With a minimum safety factor of 4.843, the structure is confirmed to be safe and efficient as a permanent lifting system. This research reinforces the reliability of FEA as a tool for assessing structural integrity in industrial applications.
