Product Description

700t Segmental Launching Gantry Crane for Highway & Railway Construction
 

Product Description

          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 Underslung or Overhead Model to meet the site requirements.
   Whenever Segmental Launching Gantry is use, efficiency is crucial. NANTE Heavy Industry Launching Gantries are designed to save every single minute in the construction sequence. Motorized mechanisms are used for continuous self-launching, electric winches with motorized travelling wagons are used for segment lifting and transporting, Spreader Beam with 360° on plane rotating, vertical tilting and angle adjustment functions are provided.

-------------------------------------------------------------Design and manufacturing features------------------------------------------------------------

1. Our glue-as-you-go procedure is a special erection method for glued span-by-span bridges. A stiff main girder allows limited pre-loading of the LG, avoiding time consuming double handling.
2. A symmetrical system allows turnaround of the LG without dismantling and re-erection. A special gantry crane, able to travel over hinges, combined with a 360 degree horizontal bearing on the bottom block, allows very flexible and smooth segment installation.
3. Tower elements placed below the support beams allow substantial changes in the longitudinal slope. This facilitates compensation or elevation differences between neighboring bridges and repositioning of the LG in a vertical direction by vertical climbing of the LG.
4. Easy extension of the support beam for overhead Launching Gantries makes sideways movement of the whole system to the neighboring bridge or over existing superstructures possible.

A launching gantry (also called beam launcher, girder launcher,[bridge building crane, and bridge-building machine, locally nicknamed the "Iron Monster") is a special-purpose mobile gantry crane used in bridge construction, specifically segmental bridges that use precast box girder bridge segments or precast girders in highway and high-speed rail bridge construction projects. The launching gantry is used to lift and support bridge segments or girders as they are placed while being supported by the bridge piers instead of the ground.
