MOVABLE SCAFFOLDING SYSTEM Main Products Applications;;;The formtraveller system was invented in 1970 and today it is acclaimed for 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 use the Formtraveller The 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. ;The Formtraveller;The Formtraveller - Cross-Support for installation on small Pierheads; ;;;;;;;;Lightweight:The use of rectangular hollow sections in the main structural components 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 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 in one week. Rolling forward on rails, the reset time is short. ;;;;;;;;;The Formtraveller - A normal working cycle may be as follows:;The Formtraveller: Arrade, Portugal;The Formtraveller: Alqueva, Portugal;The Formtraveller: Dyr?y bridge, Norway;The Formtraveller: Algés, Portugal;The Formtraveller: Loures, Portugal;The Formtraveller: Arrade, Portugal;The Formtraveller: Rio Minho, Portugal
