The Casting Crane is one of the key pieces of equipment in the steelmaking continuous casting process. It is primarily used for loading and transferring molten iron from the converter to the ladle, and for lifting steel from the refining furnace to the ladle or transferring steel to the continuous casting turnaround ladle platform.

The overall structure of the casting crane can be classified into various forms, including: double-girder double-track, four-girder four-track, and four-girder six-track configurations. The double-girder double-track and four-girder four-track forms are generally used for medium to large-tonnage casting cranes, while the four-girder six-track dual-trolley form is typically used for extra-large tonnage casting cranes.
