| Abstract: | In this paper, a new girder replacing technology, which takes the cross-track gantry crane as the girder hoister, is put forward. Assembly type gantry crane that can be assembled quickly and new patterns of girder feeding and hoisting are researched. In this way, a great deal of shortcomings of traditional technologies such as the transportation interference, long term of project and great cost are overcome. Practice shows that this technology is safe, efficient, low interference to traffic and highly applicable. |
