Due to its high strength, low elongation, wear resistance, softness, smoothness, and easy operation, the cable is widely used in industrial service. Cables can be divided into three types of cables according to the structure: three strands, eight strands, and twelve strands.

Mainly used for ship equipment, fishing, port handling, power construction, oil exploration, national defense industry, sporting goods and other fields.

The use of ropes Note: The rope should be carefully checked before each use, mark the tag label inserted ring eyes, whether the rope cut, broken stock, broken wire, kinks and other damaged parts, such as no exceptions and defects that It can be used normally; when the rope is deployed, the rope should be released from the rope end in the circle, and the rope should be released counterclockwise. If the rope is deployed counterclockwise, rope kinking occurs. If kinks occur, the ropes should be put back into the loops, the loops turned over, and then the ropes pulled out from the center. It is better to unwind the ropes on a turntable where the ropes can be pulled from the outer rope ends. If a person stands under an over-tightened rope, a danger will occur. Once the rope is out of control, a huge rebound will occur, which may result in casualties.

If the rope is unwound from the rope shaft, the rope shaft itself should be free to rotate. It is easy to use a pipe to pass through the center of the rope shaft, but it is forbidden to erect the rope by erecting the rope shaft; if the rope is unrolled from the pulley device, the pulley The ratio of the diameter D to the diameter d of the rope should be more than 5, but the ratio of certain high-performance fiber ropes can reach 20. For the ropes, it is recommended that the diameter of the pulley groove is 10%-15% larger than the rope diameter. If the arc of the rope is 150 degrees in contact with the wheel groove, the rope can achieve the best stress state. The pulley flange height should be at least 1.5 times the rope diameter. To prevent the rope from running out of the pulley. In addition, the pulleys should be inspected frequently and the bearings should be regularly maintained to ensure smooth rotation of the pulleys. The rope should be scrapped or discontinued when the following conditions occur: the rope is obviously scorched or melted; the linear distance is equal to the length of the rope, and the surface rope or strand volume is reduced by 10%; the rope is exposed to extreme temperature extremes Ultraviolet exposure is degraded, and the surface of the yarn is fragmented; ropes appear in severely damaged hot-melt, hardened, flattened areas; the number of yarns affected by melting or fusion exceeds 20%.

By understanding the correct use of the cable, it is possible to reduce excessive loss or damage to the cable during the operation and extend the service life of the cable.
