Each spool holds 800 metres of 3.75mm-diameter wire – sufficient to cover two metres of the main cables. The new wrapping wire is first welded to the existing free end on the cable and then wound on to a freshly applied coating of red lead corrosion-inhibiting paste. The wrapper is controlled by a remote pendant and includes a frame to allow it to be towed along the cable. A second frame hooks on to two permanent hand-strand wires running above the main cable to counteract the rotating action of the motor.
The high-level inspections are due to be completed in September.
