Non-destructive steel cable testing with minimum disruption to operations

The deck of the 772-metre long cable-stayed bridge in Wesel, Germany, with its four carriageways plus footpaths and cycle paths on either side, is supported by a 130-metre high Y-shaped pylon and 72 steel cables.

At the end of 2020, DMT successfully inspected the 10-year old pylon and all cables in just 3 weeks with minimal disruption to ongoing traffic. This included determining the cable force by means of natural frequency measurement, the electromagnetic and visual inspection of the full accessible length of all cables and a visual inspection of the bundling elements and anchorage areas. Upon completion of the safety inspection, the bridge could be fully opened to traffic again.

With our own accredited testing laboratory for non-destructive and destructive rope testing, DMT’s safety experts are contracted to examine the performance and durability of steel cables of bridges, cable cars, cranes, buildings and other structures all over the world.
