Overhead 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. Alpi’s Systems are designed to minimize the requirement for support crane-age during assemble, commissioning and dismantling.
Light Weight equipment,
Minimum of Deflection,
Rapid and Easy Commissioning
Overhead Model Form Traveller
Huada Heavy Industry Overhead Form Traveler are easier to be use compare to under slung Model. And it is easier to be modified for future usage. Our Form Travellers are with good quality modular connection, designed for future modification and repeated usage for many years. We supply good quality metal formwork on Huada Heavy Industry Form Traveller. We also provide plywood formwork system as it is a more economical solution.
Concreting Support, self-launching operation, level adjustments are all by means of hydraulic system. Erection of the traveler on the pier top can be as short as 1 week. All major parts join together by pin connection, which promises speedy erection and high accuracy design.
