U type bridge erecting crane 

  U type bridge erecting crane  is a professional design for U type bridge machine required for erection of city rail transit construction beam. As a kind of structure section, the U beam has good noise reduction effect, low construction height, high utilization ratio of cross section space. Beacause of U type beam for thin-walled opening structure, the traditional bridge rack beam cannot be applied directly. Unable to realize the traditional function of carrying beam traversion, beam body installation can only be achieved by traversing the crane. Therefore I Shenghua heavy group U type bridge erecting machine with "front overhead crane beam, acquired vehicle girder, two cranes synchronous walking, then synchronized fall beam" of the process, simple operation, safe and stable.
