Launching Gantry

There are various kinds of launching gantries available, the choice of which depends upon the geometry of site and construction sequence adopted by the designer. 

The Segmental launching Gantry is used in the erection of precast segmental viaducts for span by span and balanced cantilever methods of construction. The self launching gantry is suitable for both straight and curved bridge construction.

And the pre-cast full span launching method of construction is one of the fastest techniques used in launching of long viaducts and high speed railway.
