Steel Mill Used Casting Double Girder Overhead Crane for Molten Steel Lifting

Overhead crane is a type of bridge crane found in foundry plant, industrial environments, such as lifting the casting ladle in steel mill.
The double girder overhead bridge crane consists of parallel runways with a traveling bridge spanning the gap. A hoist, the lifting component of a crane, travels along the bridge.
In many instances the cost of a bridge crane can be largely offset with savings from not renting mobile cranes in the construction of a facility that uses a lot of heavy process equipment.

Overview:

Molten Steel Lifting Crane

Bridge foundry crane with hook is mainly used at the place where the molten metal is lifted. The working class of the complete machine is A7, and the thermal-protective coating is added at the bottom of the main girder.The assembling and test of the crane conform to the document No. ZJBT[2007]375 WHICH WAS ISSUED BY General Administration of Quality Supervison, Inspection and Quarantine of China.
