1. Middle support legs do not move on the bridge deck, it is unnecessary to lay longitudinal sliding rails, which reduces the pressure on the bridge deck as well as saves construction cost, thus the launching gantry has a larger adaptability to the box type precast girder.

2. The launching gantry uses support legs to move forward by itself, so it can better adapt to longitudinal and lateral slope in the actual working condition as well as make the bridge deck bear safer and more reasonable force;

3. Front support legs and middle support legs can be adjusted at random, core plate has adjustable angle, which make the launching gantry better adapt to construct curved bridge and skew bridge; as constructing the skew bridge, the position of front support legs and middle support legs can be changed according to the angle of skew bridge, the machine can construct skew bridge with angle below 45°.
