Metallurgical special double girder bridge crane

May 17, 2019
Metallurgical special double girder bridge cranes can participate in specific process operations in the steel production process. The basic structure is similar to that of ordinary bridge cranes, but special working mechanisms or devices are also installed on the lifting trolleys. The working characteristics of this kind of crane are frequent use, poor conditions and high working level, there are mainly five types.
 
Casting double girder bridge crane
It is used to transport molten iron into mixed iron furnace or steelmaking furnace, or to transport molten steel into the continuous ingot casting equipment or the steel ingot mold, etc., the main trolley lifts the barrel, and the auxiliary trolley carries out auxiliary work such as flipping the barrel. 
 
Clamp double girder bridge crane
Use the clamp to lift the high temperature steel ingot vertically into the deep pit soaking furnace, or take it out and put it on the ingot cart.
 
Ingot double girder bridge crane
It is used to forcibly remove the steel ingot from the ingot mold.
 
Feeding double girder bridge crane
Used to add the furnace burden to the open hearth furnace. The lower end of the main trolley is equipped with a pick rod for picking up the material box and feeding it into the furnace; the auxiliary trolley is used for auxiliary work such as repairing the furnace.
 
Forged double girder bridge crane
Used to forge large workpieces with hydraulic presses. A special hopper is suspended on the main trolley hook to support and flip the workpiece; the auxiliary trolley is used to lift the workpiece.
