Hydraulic System Segment Lifter Tailored for Various Erection Requirements
Segment lifter is a kind of bridge construction equipment.
NANTE has developed several types of Bridge deck erection system segment lifter tailored for the various erection requirements and conditions of precast segmental viaduct. The technology has been used successfully to complete several large balanced cantilever bridges worldwide. The crane is fitted with electric winches and is launched forward by hydraulic system. The lifter can also be equipped with steel wheel/rails or rubber tyre mounted for increased mobility.
The form traveller system is acclaimed for enhancing the cost-effectiveness of bridge projects worldwide. The system is lightweight, versatile, easy to assemble and operate, rolling forward on rails, the system can be reset quickly and easily.
The form traveller is used for free cantilever construction of post-tensioned box girder - and cable-stayed concrete bridges. Engineering to international standards, the system provides an exceptionally rigid formwork, with a maximum deflection of less than 25mm at full loading.
The Standard form traveller is designed for a maximum segment length of 5 m and load capacities (concrete and formwork) varying from 250t to 400t. The steel weight depends on the cross section of the bridge in question, but will normally vary from about 25t to 65t correspondingly. The Standard form traveller may be adapted to suite almost any cross-section, and is easily adjustable during operation to variations in segment length (up to 5 m), section height, web thickness, and deck width.
Form Travellers are widely used in the following applications:
