Critical Tensioning for Cable Anchor for Suspension Bridge

At the time of opening in July 2000, the Øresund Bridge was the longest combined road and rail bridge in Europe at 7,845 metres and connects the countries of Denmark and Sweden.

The cable anchor, which clamps the huge steel wire cables of the bridge needed bolting together and given the safety criticality of the application tensioning was the chosen method, ensuring the essential retained loads were maintained in the bolting.

Each cable anchor block had 20 studs that needed tightening simultaneously and in a controlled manner to ensure a high integrity joint.
