Wing Travellers
A wing traveller works in a similar way to the MSS and the form traveller machines, acting as a movable concrete mould to complete the full deck width. Concrete is poured into both sides of the machine at the same time, enabling workers to cast sections of the outer deck on each side of the viaduct with or without struts. Once the concrete has set, hydraulic jacks push the machine forward to the next position and the cycle is repeated. Both the overhead and the underslung WT are designed for the same purpose. The underslung wing traveller system can be adapted to different types of bridges, such as cable stayed structures, leaving no obstructions to temporary or permanent cables as well as giving the opportunity for an easy «back – launch» to its initial installation position. For projects where reinforcement is to be prefabricated, the underslung wing traveller is the perfect choice. The external formwork for this WT is supported from below, leaving no obstruction to place prefabricated bottom slab, web and top slab reinforcement.
