Insulated Overhead Crane

Insulated overhead crane is widely used in metallurgical plants to handle the electrolysis equipment for aluminum, magnesium and other nonferrous metals. The overhead lifting equipment is mainly made up from four parts including box shape girder, end trucks, trolley and electrical equipment. To protect the driver from electric shock in material handling, the bridge crane for steel industry is equipped with insulation devices at some electriferous parts. In addition, it adopts double brake to ensure totally safe lifting.
