The above production process and aerial crane device are all existing technologies; the platform is finally formed after a series of production and processing such as the loading station 1, the beam spot fixing station 2, and the overall forming station 3. In actual production, the prefabricated profiles are first transported to the loading rack 11 of the loading station 1 by the aerial crane. The telescopic hanger 12 on the loading station 1 can place the profile on the roller conveyor frame 14 through the strong magnet 13, and then convey the profile to the beam fixing station 2 through the roller conveyor frame 14.
