5.56 Million Meters of Steel Wire Stranded

5 June 2017

Using approximately 5.56 million meters of steel wire, with diameters from 1.85 through 4.22 mm, FATZER produced 4 carrying ropes with a diameter of 72 mm, each measuring 4,900 meters in length, and 2 haulage ropes 47 and 41 mm in diameter, each measuring 4,610 meters in length. The theoretical breaking force of each individual carrying rope is 6,772 kN – approximately 690 tons! What's really special about the INTEGRA-Data type carrying ropes, which consist of 210 individual wires, are the fiber-optic cables integrated in their core, which provide an assurance of reliable data transmission between top and bottom stations lasting decades. On account of the heavy weight of each of the ropes (153 tons), a special logistics solution was required for transportation to the bottom station at Eibsee. Working together with its transport partners, FATZER designed and developed a solution exclusively for this project. For better vehicle load distribution and maneuverability, the steel rope load was shared by two linked heavy-duty transporters with a total weight of around 250 tons. This approach meant that even bridges and roads that would not be suitable for the static load of the equivalent individual weightcould be navigated with ease.
