It is mainly used to lift and install full span concrete girders for general railway and highway bridge.
2. Main features and advantages of Walking type bridge girder launcher
Main features and advantages are as following:
● First-made honeycomb girder in China features light self weight, heavy load, high stiffness, low deflection and strong wind resistance etc.
● Structure of walking type bridge girder launcher is reasonable and reliable, suitable for China bridge.
● Pin connection between main girder sections, reliable quality and convenient installation
● It doesn’t need to pave the longitudinal rails. It not only can reduce the stress of bridge, but also can save the cost of construction. It has a wide adaptability for the box girder.
● Adapt the longitudinal slope and transverse slope better, its legs can move forward by its own force;
● Front and middle legs can be adjusted randomly and core plate with adjustable angle which can adapt the erection of curved bridge and Slope Bridge. It can be used for 45°and less than 45° any angle slope bridge.
● Transverse trolley is added to the lifting trolley, the whole machine traverses with boundary beam which resolve the problem of installation of boundary beam.
