After several months during which tonnes of steel left the Kremsmueller production facility every week in the form of pipeline segments, it was time for the first of five branch junctions to start their journey to the hydroelectric power plant in the Tyrolean Kaunertal. At a height of 5 metres and a width of 6 metres, the dimensions of the branch junction are truly awesome. The total weight is 120 tonnes.

Using a self-propelled heavy-duty transporter with a height-balancing function, the Y-shaped component was moved into the tunnel. The separate control of wheels and axle lines helped to keep the platform with the branch junction horizontal. When the time came to move the branch junction to its intended place, it was also time for correct-to-the-nearest-millimetre work.

In the tunnel, the pipe segments are welded to one another. Later, a pressure of 80 bar pro cm² will be exerted on the lower part of the tunnel armouring of the pressure shaft. That equals 800,000 kilograms per square metre. The welding skills of the team play a very significant role here.
