Beam Launcher Process description:

1, Installation the launcher, check the functioning of the institutions, subject to normal after the main girder leveling, and place the girder at the end of the launcher;

2, Lift the front legs and rear leg so that the main beam is elevated and the middle leg lifts off ground, and then move the middle leg front. And move the two trolley rear;

3, Loose front leg and rear leg, let middle leg and rear leg support the main girder and level the main girder again, and then move it to from about 35m;

4, Front trolley lift bridge girder at the end and make flatbed support the other end, which can make the main girder front movement steady;

5, Move the main girder as well as the flatbed front 10m, then make the front leg touch the new pier and support the main girder again. And then finish the work of launching the girder. Erection schematic diagram of the side beam
