The wheel/rail type bridge erecting machine with bottom guiding beam was used in the construction of the 24 m single box concrete bridge on the double tracked Qin Shen dedicated passenger line. The machine is simple in structure and low in gravity center. It feeds the girder, locates it and cranes it at three points. It then can tune the girder position. The girder carriage uses the vertical and horizontal hinges to support rigidly and flexibly the concrete box girder so that the carrier can negotiate curves without distorting the girder itself. This achievement obtained the second class award of the national scientific and technological progress 2001.
