NUMERICAL ANALYSIS OF SLINGS WITH SPREADER BARS IN SHIPPING CONTAINERS LIFTING TECHNIQUE

Containerization is the practice of consolidating multiple cargos in a container for transport as a single unit. Containers are loaded and unloaded using mechanised equipment. This equipment includes lifting gears such as slings and spreader bar. This thesis discusses arrangement of slings and spreader bar to find optimal solution for container lifting with less consumption of time. The models were generated on SOLIDWORKS and then imported onto ANSYS for the further analysis. First model is a container with two slings, second model is a container with two slings and spreader bar, third model is a container with two slings and multiple spreader bars. . A static structural analysis were carried out on these models. Total deformation values and equivalent stress values were generated for these models. From the comparison it shows the third model is the better configuration. . For the feasible configuration inertial load analysis, thermal analysis, fatigue analysis, and limit load analysis were conducted to find the safety of the feasible model. It concludes that the better model shows a percentage reduction of deformation from the first model, the stress generated is within the allowable limit, and it is safe under elevated temperatures.
