We were ask to come up with a solution by the Alaska DOT to handle big rimmed tires in large maintenance shops that are usually filled with equipment being repaired. We had to do serveral iterations but came up with a functional slings that the DOT was happy with. When the Muni of Anchorage equipment shop saw it, they also bought several. We have customers from Quebec to Alabama, Texas, California and as far north as Prudhoe Bay, Alaska!
