After several months of preparation, Ævia’s teams successfully carried out the jacking down of the Sylvain Dupuis Bridge on the Brussels Ring Road on behalf of Bruxelles Mobilité - Brussel Mobiliteit.

The operation was carried out using a Computer-Assisted Lifting (CAL) system, allowing precise control of the pressure and movement of 40 hydraulic jacks with capacities ranging from 45 to 250 tonnes.
The jacking was performed at a height of 1.5 metres on specially dimensioned temporary supports.
The bridge bearings were then replaced, followed by the jacking down phase.

A complex lifting operation successfully completed in partnership with INCYE Etaiements, Butonnages et Etançonnements.
