VSL Heavy Lifting Systems (Strand Jacks) at Queensferry Crossing
Firth of Forth, Scotland, UK · 2011-2017 (Queensferry Crossing construction period) · £1.35bn (Queensferry Crossing total)
The judgement call
Account-gated at launchVSL's heavy lifting systems, particularly their hydraulic strand jacking technology, were critical for the construction of the Queensferry Crossing. These systems enabled the precise and safe movement of large and heavy bridge elements, demonstrating advanced engineering solutions for complex bridge construction. The use of such specialized equipment was essential for the efficient and accurate assembly of this iconic cable-stayed bridge.
Key engineering challenges
Handling and positioning massive bridge sections and components with extreme precision. - Working at significant heights and over water in challenging weather conditions. - Ensuring the structural integrity and stability of the bridge during construction phases.
