What are the precautions for mixed rope?

The mixed rope is the most popular choice for marine rigging applications because the mixed rope has higher tensile strength, great flexibility, and better abrasion resistance is easy to handle and manipulate and can float on the water. The next is the introduction of hybrid rope considerations.

Pay attention to check

The polyester line in each use before should check carefully mark label insert knitting ring eye, the rope body has no cut, broken strands, broken wire, kink and other damaged parts, such as no abnormalities and defects can be used normally. When unfolding the mixed rope, should start to put out the mixed rope from the end of the rope inside the circle, the mixed rope should be put out counterclockwise. If unfold the rope is counterclockwise, it will occur the rope kink. If produce kink, should put the mixed rope back to the rope circle, flip the rope circle, then pull out the rope from the center, the better way is to unfold the rope on a turntable, at this time can pull out the polyester marine rope from the outside rope end. If the personnel stand under the rope which is overstretched, it will be dangerous, once the mixed rope is out of control, it will produce a huge pulling force rebound, which is likely to cause casualties. If unfold the rope from the rope shaft, the rope shaft itself should be free to rotate, use a tube through the center of the rope shaft will be easy to do this, but forbid the vertical release of the rope shaft to unfold the mixed rope. If unfold the mixed rope from the pulley device, the diameter of the pulley D and the diameter of the roped ratio should exceed but for some high performance, the fiber rope ratio can reach 20.

Stop using

The polyester marine line appears the following situation should be scrapped or stop using: mixed rope appear obvious scorch or melt, straight-line distance is equal to mixed rope length on, surface rope yarn or rope strand volume decrease 10%. Mixed rope exposed to the extreme temperature environment of the super range; UV exposure degradation, rope yarn surface into fragments. The mixed rope appears in the severely damaged heat melting, hardening, and flattening area. The number of melt or fusion affected rope yarns exceeds 20%.

Diameter selection

For polyester fishing ropes, it is recommended that the diameter of the sheave groove is 10%-15% larger than the rope diameter. If the rope in the sheave-groove contact arc is 150 degrees, the mixed rope can achieve a good stress state, the height of the sheave flange should be at least 1.5 times the rope diameter, to prevent the mixed rope run out of the sheave. In addition, should often check the pulley, and regular maintenance of the bearing to ensure smooth rotation of the pulley.
