Steel Mill Overhead Casting Crane

QDY Steel mill overhead casting 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 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 Supervision, Inspection and Quarantine of the People' s Republic of China. The place where molten nonmetal material and red-hot solid metal is lifted also can refer to this document, (note: HO in the below figure is the Increased height of buffer of the crane)
