Abstract: Taking the suspended monorail testing line project of CRRC Qingdao Sifang Co., Ltd as the engineering background, and according to the structural features of beam-rail integration, the manufacturing process of the open box-type track beam structure used as the wheel/rail running surface is elaborated. Then, the track beam structure for suspended monorail is introduced, difficulties in the manufacture of the track beam are pointed out, manufacturing schemes are compared and selected. Finally, the manufacturing processes of the track beam structure for suspended monorail and the key points in precise control are illustrated systematically.
