| Smarter, Any way you look at it

A ladle handling crane lifts large, open-topped cylindrical containers (ladles) filled with liquid metal to the basic oxygen furnace (BOF) for mixing. The raw materials of iron ore and coking coal are combined to produce solid metallic iron, and this iron added to scrap metal creates steel. The crane also transports the liquid iron or steel from the BOF and electric arc furnace to the continuous casting machine.

A Konecranes ladle handling crane is designed specifically for the extreme environment of heat, dust and hot metal in a melt shop. Therefore, we include features such as Increased working coefficients, a differential gear reducer, redundancy in all critical systems, a backup brake on the rope drum, and motion limiters making the crane and application safe and reliable. It can also be used for teeming and casting.
