Testing in wire rope manufacture Easydur has developed an optical system, capable of monitoring the production of strands.

The system is incorporated into the production line to monitor the interlacing of cables. If one or more cables break, the system will stop the stranding machine. Easydur also has a range of universal machines for tensile tests on cables, bars, chains, ropes and hooks. All machines are equipped with computers and advanced software.

WireCo WorldGroup has been awarded the contract for wire rope suspenders and cables to be used on the new San Francisco Oakland Bay Bridge. The distinctive, single tower structure will be the world’s longest single span, self-anchored suspension bridge. The wire rope suspender and cables that WireCo will engineer for this project include 75mm and 90mm wire rope suspension hangers, which connect the floating bridge box girders and the tower. As a result, it will be the first suspension bridge engineered to require no connection between the tower and the deck. In addition, the company will supply the hand rope assemblies that allow access to the 2.56 foot diameter main cable. WireCo to supply bridge cables

Using an elegant, futuristic design that mixes form with function, the new structure will carry daily traffic in excess of 280,000 vehicles or more than 102 million vehicles yearly. The bridge’s single tower rises 525 feet and the bridge connects the 1.2 mile elevated skyway viaduct from Oakland to Treasure Island with two, parallel roadways (each with five lanes) and a 15 foot wide bicycle/ pedestrian path. WireCo recently moved its corporate headquarters from St Joseph to Kansas City and operates a manufacturing facility in St Joseph.
