Double-girder bridge casting crane

The double-girder bridge casting crane is a robust overhead crane specifically designed for handling molten metal in steel mills and foundries. It features two main girders, a main hoist for ladle tilting and pouring, and an auxiliary hoist for ladle preheating, cover handling, and other support tasks. With lifting capacities typically from 50t to 450t and duty class A7‑A8, this crane is built for continuous, high‑intensity operation under extreme heat, dust, and heavy shock loads.

[1] Steelmaking Plants – Transporting and tilting molten steel ladles from converters to continuous casting machines. [2] Foundries – Pouring molten iron or steel into molds for large castings such as machine frames, rolls, and ingots. [3] Non‑ferrous Smelters – Handling ladles of molten aluminum, copper, or zinc with heat protection. [4] Ladle Pretreatment Stations – Hoisting ladles for desulfurization, alloying, and slag removal.

[1] High Thermal Protection – Heat shields, insulated platforms, and special coatings protect components from radiant heat. [2] Large Load Capacity – Double‑girder structure supports loads up to 450 tons or more. [3] Fail‑Safe Braking – Dual brakes and emergency holding systems ensure safety when handling molten metal. [4] Smooth Tilting & Positioning – Precision ladle tilting mechanism allows controlled pouring with minimal splash. [5] High Duty Cycle – Designed for A7‑A8 duty class, 24/7 continuous operation in harsh environments.
