Four Girder Casting Crane

The four girder casting crane is a heavy‑duty overhead crane specifically designed for handling molten metal in steel mills and foundries. It features four main girders (two outer and two inner), providing exceptional rigidity and redundancy. The main hoist is used for tilting and pouring ladles, while an auxiliary hoist handles ladle preheating, cover removal, and other auxiliary tasks. With lifting capacities typically ranging from 50t to 500t+ and duty class A7‑A8, this crane ensures safe, reliable, and continuous operation under extreme heat, dust, and high‑frequency working conditions.

[1] Steelmaking Plants – Transporting and tilting molten steel ladles from converters to continuous casting machines.

[2] Foundries – Pouring molten iron into molds for casting large components such as engine blocks, turbine housings, and heavy machinery parts.

[3] Non‑Ferrous Metal Smelters – Handling ladles of molten aluminum, copper, or zinc under high‑temperature conditions.

[4] Integrated Steel Mills – Serving the BOF (Basic Oxygen Furnace) or EAF (Electric Arc Furnace) shops for hot metal transfer.

[5] Ladle Repair and Pretreatment Stations – Hoisting ladles for cleaning, lining repair, and preheating before filling.

[1] High Thermal Protection – Heat shields, insulated platforms, and special heat‑resistant coatings protect all critical components.

[2] Ultra‑High Load Capacity – Four‑girder design provides superior strength, capable of lifting over 500 tons.

[3] Fail‑Safe Braking and Redundancy – Dual braking systems and independent mechanical backups ensure safety when handling molten metal.

[4] Smooth and Precise Tilting – Specially designed ladle tilting mechanism allows controlled pouring with minimal splash.

[5] High Duty Cycle – Designed for A8 duty class, operating 24/7 in harsh environments with minimal maintenance.
