[0002] A steel structure beam refers to a beam composed of steel materials such as steel plates and steel columns. In order to assist production, during the production process of steel structure beams, it is necessary to turnover the fittings to facilitate the assembly and connection of each workpiece. Currently, there are many related turnover devices.
