Wings formwork travellers for Mersey Gateway Bridge
Location: Widnes, (Liverpool)
Year: 2015 to 2017
What was the challenge?:
Avoid the use of scaffold and the lowering of FT on each movement and internal form adaptability to the different cross sections.
Automatized operation either for external and for internal form, avoiding the vertical movement and stripping using deformation of the structure. Internal form floating system, with a capacity of withstand 300 tons of concrete. The cable was needed to be anchored prior launching, being a real challenge to develop a inner form capable to enable the PT of the stay cable after pouring.
