Copenhagen’s Lille Langebro Swing Bridge
Realdania for Københavns Kommune
In Partnership with
Buro Happold, Wilkinson Eyre, Niras, Urban Agency, Speirs & Major
We worked together with Buro Happold, Wilkinson Eyre and Niras to produce the design of this architecturally striking and technically challenging bridge. Our role was to produce the detailed concept design of the operating equipment which allowed the architectural vision to be realised whilst also ensuring that the operating equipment, used to control the 2 central moving decks, is reliable and maintainable.
The two moving spans are mounted on large diameter slewing bearings which have integral teeth. These teeth engage with pinions, driven by four 15kW electric motor gearbox units, resulting in the span rotation. The bridge operating cycle takes 109 seconds to open and 144 seconds to close.
