[0042] The technical solution of this patent will be described in further detail below in conjunction with specific embodiments.
[0043] See Figure 1-4 , The assembling process of double-box composite beam structure with equal height includes the following steps:
[0044] S1, steel box girder transportation and lifting:
[0045] After the assembling and painting of the single steel box girder is completed, the finished steel box girder is transported to the steel box girder lifting area by the girder truck, and then the steel box girder is smoothly connected to the welding platform through the traverse device, and the gantry crane lifting system is used for the order The steel box girder is lifted, hoisted to the welding platform, and the plane position and elevation are adjusted in place.
[0046] S2, steel box girder installed in place
[0047] S3. When installing the first section of the steel box girder, use the gantry crane to hoist and transport the first section of the steel ...
