Double Girders Or Beams Electric Overhead Bridge Traveling Foundry Casting Crane
Introduction
QDY 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 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.
The metallurgical / foundry crane is the main equipment in the steelmaking and continuous casting process, which is used for the transport, pouring and mixing of liquid metal in the smelting process, such as hoisting and transferring liquid ladle. It can timely and quickly complete the displacement of lifting and transporting heavy objects in the process of metallurgical production through lifting hooks or other pick-up devices, and now it has become the main lifting and transportation equipment in the smelting workshop of steel plants.
