The invention relates to a suspension monorail case-type beam inspection tour apparatus, which belongs to the technical of traffic engineering. The beam inspection tour apparatus comprises a moving platform and the following functional units arranged on the moving platform, five optical detection units which respectively correspond to five positions of a left track, a right track, an end face of a case-type track beam inner wall and two side surfaces; a system control unit, a system memory unit, a data processing unit, a communication unit and a radio frequency identification unit; wherein the radio frequency identification unit, the optical detection unit, the system memory unit, the data processing unit and the communication unit are respectively connected with the system control unit, and the system memory unit is connected with the data processing unit. The suspension monorail case-type beam inspection tour apparatus can help even substitute artificial inspection tour for crack detection, corrosion detection, gauge inspection and moving surface flatness detection.
