Giant TBM accepted and heading for Italy Dec 2010
Herrenknecht News Release
15.62m mega-TBM factory tested at Schwanau

15.62m mega-TBM factory tested at Schwanau

Measuring a gigantic 15.62m in diameter, the world's largest TBM to date stands full height and factory-tested in the Herrenknecht plant in Schwanau ready for dispatch to Italy.
The mega EPB machine will excavate a 2.5km twin-bore tunnel on an extension of the A1 highway between Bologna and Florence, awarded by the Italian client Autostrade per l'Italia S.p.A. to a joint venture of Vianini Lavori, Toto Costruzioni Generali and Profacta S.p.A. The record-breaking machine, with an excavation diameter of 15.62m and an overall length of 130m, was assembled over a period of three months at the Herrenknecht headquarters in Schwanau where it was also commissioned and tested extensively.
As the time schedule for construction of the Sparvo Tunnel is tight, the dismantling phase will commence shortly following successful acceptance by the customer.

In January 2011, the first individual components will be shipped to Italy enabling final assembly to commence on site in February. The giant TBM is to start tunnelling the first tube near Florence in a northerly direction in May 2011 with plans for the new route to open by the end of 2013.
To celebrate acceptance of the giant machine, the customer Toto Costruzioni Generali S.p.A. invited top-ranking representatives of all the companies involved to Schwanau where the machine was presented and its functions explained. The next few weeks will see the machine partially dismantled for transport to the site in Italy.
