4、enhancing the cost-effectiveness of bridge projects world-wide. We have continually improved the Formtraveller in collaboration with major contractors. The system is lightweight, versatile and easy to assemble and operate. Rolling forward on rails, the system can be reset quickly and easily.Where to

5、 use the FormtravellerThe Formtraveller is used for free cantilever construction of post-tensioned boxgirder and cable-stayed concrete bridges. Engineered to international standards, the system provides an exceptionally rigid formwork, with a maximum deflection of less than 25 mm at full loading. TH

6、E FORMTRAVELLER CONCEPTThe FormtravellerThe Standard Formtraveller is designed for a usual segment length of 5 m and load capacities (concrete and formwork) varying from 100 tons to 600 tons. The steel weight depends on the cross-section of the bridge in question, but will normally vary from about 2

7、5 tons to 110 tons correspondingly. The Standard Formtraveller 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. For segment lengths beyond 5 m and other conditions,

8、the Formtraveller will be tailor-made.The Formtraveller - Cross-Support for installation on small PierheadsWhen the pier head is too small to allow normal assembly of the Formtraveller, our Cross-support solves the problem.

20、mponents and recoverable high strength bars in all stays and ties reduces the total steel weight to a minimum. Flexible design:The Formtraveller may be adapted to almost any cross-section and is easily adjustable during operation to variations in segment length, box height, web thickness, deck width

21、 and road alignment (gradient, curvature, super-elevations). Small deflections:The vertical deflection at the front of the Formtraveller is less than 25 mm at maximum load. Formwork beams are designed for a maximum deflection of L/400 of their length. Easy assembly:One Formtraveller may be assembled

22、 in one week. Rolling forward on rails, the reset time is short.
