Underslung Form Traveller
Huada Heavy Industry Form Traveller System are used for Balance Cantilever （cast-in-situ post-tensioned） segmental construction method, and this system can be used for bridges such as free cantilever, cable stayed bridge and arched bridge.
The Formwork Traveller System can be designed as overhead or underslung type to adapt to many bridge cross-sections, including single, double or triple box girder, U, T section etc.
The Form Traveller System is highly flexible and allows efficient and repeated usage on bridges with different cross sections and a variety of casting lengths. Fully hydraulic as well as mechanical systems are built into the Form Traveller System, which ensure full precision control during construction of the bridge and operation of the entire system.
Light Weight equipment,
Minimum of Deflection,
Rapid and Easy Commissioning
UnderSlung Model Form Traveller
Underslung Form Traveller have its main parts hang under the completed bridge hence providing a clear space above the formwork, which means prefabricated reinforcement cages can be install easily. In certain cases Underslung Form Traveller providing the only solution which Overhead Form Traveller cannot give, for example on the construction of Arch for the Arch Bridge or when dealing with any slanting column structure or for certain Cable stay bridges.
