The twisted steel wire rope is made of high quality galvanized steel wire rope (1*19W, 1*25FI).
One, its characteristics:
1, in the free state of tension, the steel wire rotation angle is equal to 0, synthetic torque equal to 0.
2, rope soft good, after lifting tension not knot, not winding, not broken stock, no gold hook.
Two. Main use of torsion proof wire rope:
1. used for power line traction, gravitational extension wire, or as a traction rope for line laying. But the diameter of traction grinding core should be no less than 15 times the rope diameter.
2, the wire rope can also be used as a sling instead of ordinary steel wire under the condition of tension.
Three quality requirements:
1, rope in the manufacture length, according to the user requirements length + 2% delivery acceptance.
2, the rope does not allow any form of joints per share.
3. The length of the inserting sleeves at both ends of the rope is not less than 5 pitch lengths, but also according to the requirements of the users.
4, rope appearance should be no jump stock, no wrong stock, disorderly stock, loose stock, hurt stocks and so on.
5, a square or hexagonal cross section of the rope, the opposite is composed of strands of the same direction as the diagonal rope.
6, the rope breaking tension is calculated according to the tensile strength of the rope, and the safety factor (safety factor 3) should be taken into account when selecting the user. The tension of the rope can not be taken as a practical pull.
