<p>A highly adhesive polyurethane, epoxy or polyester resin, is applied in a marquee or a structure assembled from transportable prefabricated units, on the site, in the course of unwinding the cables from the delivery reels. A continuous steel strip of high duty allow with chromium, nickel, molybdenum and titanium, and having good welding qualities is then folded round the circular or hexagonal rods and welded lengthways. Or the cable may be wrapped in the steel strip and welded spirally. For the erection, special clamps are fitted and suspended from cables; the lifting being automatically controlled, so that the minimum radius of curvature at which damaging deformation of the protective sheath and corrosive protection would occur, is always exceeded. A first class and highly durable protection against corrosion, needing none at all or very little maintenance is given to the tensile members of suspension bridges and similar structures, provided as works assembled cables consisting of a bundle of parallel wires; The equipment ensures their erection without the possibility of damage.</p> |
