[0002] With the continuous development of domestic expressways, prefabricated box girder construction technology has been widely used in bridge engineering construction, and its construction technology is also becoming increasingly perfect.

[0003] According to the construction environment of the bridge, a suitable bridge erection machine is selected. Currently, a transport-erecting machine is commonly used for erecting beams. However, the transport route needs to have a large width and height when the transport-erecting machine is used to transport beams. When the transport route cannot meet the required transport height of the transport-erecting machine due to other reasons, a beam transport vehicle is usually used to transport the prefabricated box beams. In this way, the prefabricated box beams are transported to the designated location, which is convenient for the transport-erecting machine to install the prefabricated box beams.

[0004] Since prefabricated box girders are large in size and heavy in weight, after the prefabricated box girders are transported to the designated location, the prefabricated box girders are removed from the beam transporter, moved horizontally, lifted, and erected through the entire operation process. During the removal process, the beam transporter can only be fixed, which increases the danger of the beam transporter. In addition, since the prefabricated box girders are placed on the beam transporter, it is not convenient for the beam transporter to reverse the prefabricated box girders. Utility Model Content
