A very useful feature of non-rotating wire rope is that the rope is effectively improved and becomes soft; The recoil force is small, will not form a winding knot; Non-rotating performance can be continuously improved. Therefore, the non-rotating wire rope installation is convenient, safe and reliable, the force is uniform, the operation is stable, and the steel wire is not easy to break when used. Even if the wire is broken, it is not lifted, and it is still lying on the original position, so that there is no scratch rope wheel or drum, and it does not affect the normal work of other kinds of steel wires.

The inner and outer layers are twisted in opposite directions, and when the outer layer is subjected to a force in the opposite direction, the inner and outer strands are twisted in opposite directions, so that the rotating force of the outer strands is limited, and the rotation Angle of the bearing object in the air is appropriately reduced. But when the free end of the wire rope rotates in that direction. When the outer strand is twisted to the opposite direction, the inner strand will be tightened, which will shorten the inner strand and extend the outer strand, but because the two ends of the rope head are already tied tight, it will force the outer strand to bulge, resulting in the separation of the inner and outer strands. If the separation problem is serious, it will damage the structure of the wire rope, so that the working load is concentrated in the inner strand rope, so that the safety correlation coefficient of the wire rope system can be reduced The use of network life will also be greatly improved and reduced.

In order to prevent the separation of the internal and external steel strands, the equal torque of the internal and external steel strands should be considered in the design and production.

1. The twist direction of the inner and outer layers should be different.

2, in addition, the diameter of each layer of rope structure can be the same or different, but the rope strands of the same layer should be the same.

3, if the use of different types of diameter steel wire technology does not rotate through the wire rope, the diameter of the thicker should be used as an outer strand to increase the wear resistance and rigidity of the outer strand.

4. The torsion parameters are calculated according to the balance conditions of the sum of the inner and outer strands, but in order to prevent delamination, the torsion distance of the inner strands can be reduced by about 15%-20% to increase the torque of the inner strands.

5. The circular strand is changed into a special-shaped strand to increase the supporting area of the steel wire rope with the drum and rope wheel.
