underslung segment launching gantry

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; for Balance Cantilever Method or Span by Span Method. Launching Gantry can be designed as Under-slung or Overhead Model to meet the site requirements.

Whenever segmental Launching Gantry is use, efficiency is crucial. HUADA 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.

Overhead LG Innovations of HUADA:
◆independent main structures, only connected by the gantry crane, allowing transverse adjustment from single to double and even to triple track.
◆Implementation of hinges on our underslung LG has made it possible to erect spans with a horizontal radius down to 75m.
◆The underslung hydraulic adjustment system permits the whole span to be adjusted in all directions to correct possible misalignments during erection.
◆Underslung LG consist of independent self-supporting main structures combined with advanced lifting equipment, creating an exceptionally flexible system for both the balanced cantilever and the span-by-span method.
