The QMD250 bridge deck crane is used to erect segmental steel box girders or concrete beams, it assembles the segments piece by piece in order, and welds them to the installed segments one by one to form an integral structure, meanwhile it travels forward and installs the segments one span at a time along the scheduled installation direction. The construction method not only ensures the quality of the project, but also solves the impact on the existing traffic, and greatly reduces the noise and dust pollution, which is very suitable for the project construction requirements of crossing rivers, railways, and traffic roads. ...
