Pure Tension: The ÖBB Tests Tensorex C+

“It’s remarkable how easy it is!” Comments like this are common in tests involving the TENSOREX C+ tensioning system. This includes the tests conducted with the patented system by the Austrian national railway ÖBB at the entrance to the tunnel for the new Western Railway in St. Pölten. The system’s unique properties are particularly important at this point, where trains can race past at speeds of 160 km/h. It is small, light-weight, easy to install, and maintenance-free.

The TENSOREX C+ system replaces conventional tensioning wheels including their weights. The intelligent interaction between a spiral spring and eccentric discs guarantees consistent tensile force on the contact wire and/or messenger wire. As a purely mechanical system, the TENSOREX C+ is maintenance-free. A patented solution that ensures the optimum level of tension, not just for the Austrian railways.
