Locked Coil Strand Cables

Eventually one or more layers of wedge shaped wires.

Locked coil strand cables.

Full locked coil ropes are a unique assembly of a classic wire rope core consisting of multiple helically twisted wires with on top of that on the outside one or more layers of profiled z shaped wires that interlock with each other. The inner layers are made of round wires twisted helicoidally over a straight core. This interlocking outer layer creates a dense rope assembly with high strength stiffness and an aesthetically pleasing smooth outer surface. Redaelli s locked coil ropes are reknown for their strength rotation resistance and reduced stretch.

Pick up adjustable locking cables that can protect construction equipment from theft and unauthorized use and keep trailers generators power tools and ladders securely locked. The best customizable rope for structural applications. Locked coil strand cables locked coil strand cables fig 4 are helical shape strands composed of two types of twisted wires. The interlocking z shaped wires provide a superior barrier against external corrosive elements and reduce internal corrosion while giving this product a desirable aesthetic and modern look.

They can be fully customized to suit every client s need and requirement including layers of z shaped wires. A core helical strand. The outer z shaped layers give the rope a smoother profile which allows for better clamping. On a tied arch bridge vertical or crossed hanger assemblies offer a visually astonishing load transfer path from the deck to the arch.

Full locked coil strands have a high metallic cross section this guarantees a higher breaking load and elastic axial stiffness with a smaller reduced diameter. The maximum diameter of fully locked coil cables available in the market is of the order of 180 mm. Material high tensile stainless steel wire inox 1 4401 aisi 316 to din en 10264 4 1 4436 1 4462 on request modulus of elasticity 130 kn mm 10 kn mm. Cables are pre stressed and measured under load to give a high accuracy dead length and to ensure the correct resistance in your structure once installed.

And a number of outer layers formed by z shaped wires arranged helically figure 21 1d. The former cable stayed bridges of modern times employed fully locked coil strands. These strands are made from the assembling of wires with different shapes. In addition when it comes to the corrosion protection bridon bekaert offers various schemes to meet the lifetime and maintenance targets you have in mind.

Commonly used in stadium roof ring cable and radial cable construction and available for both galfan coated spiral strand cables and galfan coated locked coil cables up to 180mm diameter. Full locked coil strands. En 12385 10 full locked coil strand strands are made of shaped high strength wires which are coated with galvanized or galfan then helically spun around a core.
