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.
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.
