1. Design Control
1) Control the pay-off tension of each wire in the strand and each strand in the rope to distribute the residual stress reasonably.
2) Minimize or control the friction of steel wires and rope strands when they travel in the twisting equipment, so as to control the tension and ensure the surface quality.
3) Correctly design, process and rationally use the pre-deformer, otherwise, it will affect the contact pressure between the wires, which will cause stress balance changes, and also cause scratches on the surface of the wire or strands, increasing surface defects.
4) Pre-tensioning. When the pretension is 40%-50% of the breaking force, it is good for improving its fatigue life, and the effect can be obtained when the action time is more than 2h.
5) Post-processing. After the twisting is completed, the galvanized galvanized steel wire rope can be forged or compacted to improve its fatigue life.
2. Correct use
1) Pay attention to the material, hardness, shape and size of the pulley groove and machining accuracy of the pulley used for the galvanized galvanized steel wire rope.
2) Keep it well and properly lubricated.
3) Use within a reasonable temperature range.
4) Pay attention to the influence of environment and medium.
