Wind energy complex, Trairi, Brazil

In Trairi, a city in northeastern Brazil’s Cearà state, Freyssinet completed the innovative lifting operations at the Trairi II wind energy complex, which is designed to bring down the price of energy.

Freyssinet designed and built the foundations and the 36 towers made of prestressed precast concrete with a height of 120 metres. The towers were erected with a tool specially designed for the operation called Eolift®. The method, which does not require a crane, is unique and is based on a hydraulic lifting technique long employed in civil engineering.
