Scrap mills, steel mills, rolling mills, aluminium smelters and electrolytic metallurgical plants all require powerful material handling equipment with high demands on power and data transmission systems. Reliability is the first element, and powerful material handling equipment is required, with high demands on power and data transmission systems. In steel mills, charging and ladle handling cranes must be able to work around furnaces and molten steel, usually at temperatures above 70°C. Both billet and coil handling cranes are required to operate at high speeds, precise positioning, high safety and high loads.
