The first process is 34*7, 35*7, 36*7, using the diameter of the wire, the rope is formed three times, 35W*7 is formed twice, and the small strand is in line contact. If the thickness of the steel wire is different, the density increases, the breaking force increases, the non-rotating specific gravity is 30% higher than that of the same diameter 6×19 and 6×37, the breaking force directly increases by 30%, and the wear resistance is 30% higher than that of the ordinary 6 strands of steel wire rope, so the life of the non-rotating rope is much higher than that of the 6 strands of rope. 35W*7 structure is more reasonable. The use of non-rotating wire rope is safe and reliable, the force is uniform, the stable use is not easy to break, and even if it breaks, it will not rise. It will still lie in its original position and will not scratch the rope wheel or reel. Does not affect the normal work of other steel wires, safe to provide reliable, uniform force, stable operating system, not easy to break wire during use.

Working principle

Working principle of non-rotating wire rope: the inner and outer layers twist in the opposite direction, when the outer layer is subjected to the force in the opposite direction, due to its inner and outer strands twist in the opposite direction, it will limit the rotation of the outer strand wire rope, which will reduce the rotation Angle of the load bearing material in the air, but when the free end of the wire rope rotates in the opposite direction, the inner strand wire rope will tighten, which will shorten the inner strand wire rope. Extend the outer strand wire rope, but because the two ends of the wire rope are tied tightly, the outer strand wire rope will be forced to expand, resulting in the separation of the inner and outer strand wire rope. If the separation is serious, the structure of the wire rope will be damaged, resulting in centralized management of the working load on the inner strand, so that the safety correlation coefficient of the wire rope will be reduced, and the service life will be greatly reduced.

In the design and production, the reasons for the equal torsional torque of the two layers inside and outside the strand should be considered to prevent the separation of the two layers inside and outside.
