Since 1967, Excelsior Steel, headquartered in Toronto, Canada, has been processing heavy metals, like stainless steel, copper and aluminum, for customers in a broad spectrum of industries such as hospital kitchens, railcars and exhaust systems. The company had been using a manual overhead handling crane system to move metal coils that weigh between 15,000 and 20,000 pounds. "In the manual set up, you had to look to find the coils and that took time," explains Tom Coward, president of Excelsior. "Then, if you found the one you needed on the bottom of a stack of coils, you had to move the ones on top before you could pull it out and get it into the processing system."
