Hunter Lift determined that a custom manufactured suspended beam would be the best solution to allow for maximum range of motion and lifting capacity. The profile of the custom beam was developed using 3D modeling software and finite element analysis was used to keep the component weight less than 50 lbs. The high temperature of the sodium bath dramatically reduced the yield strength of commonly used nonferrous, corrosion resistant materials, rendering them ineffective and inappropriate for this project. Hunter Lift determined that an Inconel alloy would be able to withstand the high temperature and effectively resist the corrosive effects of the acid allowing the lifting device to endure repeated exposure to the harsh conditions. The entire assembly is capable of lifting 7,000 lbs. The new coil lift allows our clients in Pennsylvania to perform the processes required in an efficient and safe manner.
The upper beam with the hanger plates attached is lowered over coils of wire. When the hanger plates are in position, the custom manufactured Inconel beam is inserted into one hanger, passed through the center of the coils and then seated in the hanger plate on the opposite side. Once the custom beam is properly seated in both hanger plates, the coils can be lifted into the sodium and acid baths. While the coils are being processed, the lifter remains submerged in the baths.
Once the coils are processed, they are set on the ground and the Inconel beam is removed. The lifter is ready to repeat the process.
