Descripción
Precast Segmental Method with a Segmental Launching Gantry (LG) is a very popular way used for the construction of bridges and viaducts with small curve and long span.
Segmental Launching Gantries are used for erecting Precast Segmental Bridges and it uses Balance Cantilever Method or Span by Span Method.
Launching Gantry can be designed as Under-slung or Overhead Model to meet the site requirements.
Underslung Segmental Launching Gantry
According to the design and site construction requirements, there are some differences between overhead and underslung segmental launching gantry, such as the design of main girder structure, segment girder hanging mode, each supporting leg structure and launching mode etc.
Whenever Segmental Launching Gantry is use, efficiency is crucial. Huada Heavy Industry Launching Gantries are designed to save every single minute in the construction sequence.
