This is a good stimulation to continue to launch the award,” said Ben van den Horn, ITA COSUF General Secretary, commenting the steering board decision to award the 2019 COSUF prize.

Tough working conditions prevail in tunnelling. The demands posed on technical equipment are correspondingly high, as e.g. gears, which must reliably cater for movement in various machines. In tunnel boring machines (TBMs) planetary gears must withstand strong vibrations, impacts, high temperatures and pronounced external pressure. These powerful gears are also applied in building cranes, drilling rigs, cutters, excavators, pumps or tracked vehicles.

From May 3–9, 2019, the World Tunnel Congress will take place in the South-Italian city of Naples. On May 9, the final day of the congress, participants will have the opportunity of joining technical visits to underground construction sites and can choose one of four interesting destinations ...

The fourth tunnel drive of the tunnel boring machine (TBM) „SUSE“ started in November 2018.
