When the prefabricated box girder is hoisted to the surface of the transport frame, the adjusting cylinder is adjusted to the lower end, and the adjusting cylinder drives the transport frame to move to the lower end and enter the adjusting groove. At this time, the height of the prefabricated box girder is reduced, the center of gravity of the transport vehicle is reduced, and the safety of transportation is ensured.
