Steel Mill Overhead Cranes

Steel mill overhead cranes (Metallurgical crane) is rely on moving along the workshop orbital direction. The overhead cranes used in steel mills are involved in specific operations in the steel production process. The basic structure is similar to ordinary overhead cranes, but the hoisting trolley is equipped with special working mechanisms or devices.

Steel Mill Overhead Cranes

Overview:

Steel mill overhead cranes is rely on moving along the workshop orbital direction, car lateral movement and hook lifting movement for work, suitable for metal smelting workshop, a special crane for lifting the molten metal and molten metal forging clasps. Generally metallurgical crane application to- 10 ℃ to + 50 ℃ environment temperature, under the temperature of 40 ℃ relative humidity is not more than 50%,  board of radiation temperature does not exceed 300 ℃. Level of job class: A7, A8 is used in the relatively busy metallurgy foundry.

Sinokocranes can provide durable lifting equipment for every stage of steel mill production: scrap yard cranes, melting shop cranes, rolling and storage area cranes.
