Product Description

Non-rotating Steel Wire Rope

The non-rotating wire rope is safe to use, reliable, and evenly stressed. It runs smoothly and is not prone to wire breakage. Even if the wire is broken, it will not be uplifted. It will still lie in the original position, so that it will not scratch the rope wheel or drum, and will not affect others. The normal work of the steel wire is safe, reliable, and the force is even. It is not easy to break the wire when it runs smoothly.
Why use the multi-strand non-rotating steel wire rope to name:
Let’s take a look at the working principle of the non-rotating steel wire rope. The inner and outer layers are twisted in opposite directions. When the outer layer is subjected to a force in the opposite direction, since the inner and outer strands have opposite twist directions, the rotation of the outer strands will be restricted. This will appropriately reduce the angle of rotation of the load-bearing object in the air, but when the free end of the wire rope rotates in the opposite direction to the twisting direction of the outer strands, the inner rope will be tightened, which will shorten the inner strands and shorten the outer strands. Extend, but because both ends of the rope head have been tightened, the outer strands will be forced to bulge, causing the inner and outer strands to separate. If the separation is severe, the structure of the wire rope will be damaged, causing the load to concentrate on the inner strands and reducing the safety factor of the wire rope. , The service life will be greatly reduced.
In order to prevent the separation of the inner and outer strands, the torsion moment of the inner and outer strands should be considered when designing and producing.
1: The twist direction of the inner and outer layers should be different,
2: The diameter of the strands of each layer can be the same or different, but the strands of the same layer should be the same
3: If the non-rotating wire rope is made of steel wires with different diameters, the thicker diameter should be used as the outer strand to increase the wear resistance and rigidity of the outer strand
4; Calculate the twisting parameters according to the balance conditions of the sum of the inner and outer strands, but in order to prevent delamination, the lay length of the inner strands can be appropriately reduced, about 15%-20%, to increase the torque of the inner strands .
5: The round strands are changed into special-shaped strands to increase the supporting area of the wire rope, drum and sheave.
