[0002] In bridge construction, the prefabricated box girder ring production line is an important part. The prefabricated box girder is a bending member that is prefabricated by pre-tensioning or post-tensioning the steel bars, and then transported to the construction site for installation.

[0003] However, the existing prefabricated box girder top plate steel bar binding work still has the following problems: during the prefabricated box girder top plate steel bar binding construction process, due to the large size and long length of the prefabricated box girder, the workers need to walk on the bundled steel bars when binding at the intersection of the steel bars, and gradually complete the entire prefabricated box girder. During the operation, the workers need to step on the right position to avoid stepping on air, which is laborious and unsafe. Therefore, it is necessary to design a mobile trolley. The mobile trolley of the prefabricated box girder top plate binding frame spans the top plate steel bars. During the construction process, it can move along the binding direction of the steel bar intersection. The workers do not need to walk or work on the steel bars. After the installation of the prefabricated box girder top plate steel bars is completed, the mobile trolley is lifted away to carry out the lifting of the steel cage.
