Independent Salt Co. | Kanopolis, Kansas
When the decades-old wooden head frame structure was nearing the stage of a catastrophic failure, Independent Salt contracted with AIG to replace it with a new steel structure. The head frame supports the large sheave wheels (pulleys) that haul up skips loaded with salt from the bottom of the mine. The steel structure was erected around the original wood frame.
Independent Salt was able to maintain full operations during demolition and construction, except for a limited shutdown during final tie-in to existing equipment.
