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 CONCEPT 6 The Formtraveller The 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 25 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, the Formtraveller will be tailor-made. 7 The Formtraveller - Cross-Support for installation on small Pierheads When the pier head is too small to allow normal assembly of the Formtraveller, our Cross-support solves the problem. It makes it possible to start free cantilevering from pier heads as small as 3 m. The procedure is illustrated through the these 4 phases: 3 m Phase 1: Assembly at pierhead as small as 3 m 8 Phase 2: Concreting of 1st segment on each side of the pier finished The Formtraveller - Cross-Support for installation on small Pierheads When the pier head is too small to allow normal assembly of the Formtraveller, our Cross-support solves the problem. It makes it possible to start free cantilevering from pier heads as small as 3 m. The procedure is illustrated through the these 4 phases. 9 Phase 3: Splitting of travellers The Formtraveller - Cross-Support for installation on small Pierheads When the pier head is too small to allow normal assembly of the Formtraveller, our Cross-support solves the problem. It makes it possible to start free cantilevering from pier heads as small as 3 m. The procedure is illustrated through the these 4 phases. 10 Phase 3: Splitting of travellers The Formtraveller - Cross-Support for installation on small Pierheads When the pier head is too small to allow normal assembly of the Formtraveller, our Cross-support solves the problem.
