THE SITUATION
ArcelorMittal, the world’s leading steel and mining company, covers all of the key steel markets, from emerging to mature, in more than 20 countries. At its Dofasco subsidiary in Ontario, Canada, the company had been using an overhead crane for the assembly and disassembly and transport of backup chocks used in the manufacture of rolled steel. The operation required multiple workers to attach bearing housings to backup roll shafts and frequently resulted in costly scoring damage to the backup roll.
