Description

Technical Parameters

QDY type metallurgical bridge crane is used in the heat and high dust severe environment and lifting molten metal frequently with working duty A7. Main working process: used in converter adding material bay to charge hot metal to the converter and lift hot metal in refine bay to refine furnace or molten steel bay that lift molten steel to ladle turret. The crane is comprised of the bridge, trolley, long travel system, electrical equipment, etc. All of work operation can be finished in the cabin.
