The rope has kinds of good properties such as high tensile strength, impact resistance, abrasion resistance, flexibility, lightness and softness. It's multi-strand ropes aim to tying ships.
If sort mooring rope by materials, there are polyester, polypropylene, ultra-high molecular polyethylene, aramid and nylon composite rope, etc.
Generally, mooring ropes are polypropylene or polyester ropes. According to the processing structure, chemical fiber cables are divided into two types including 3-strand,8-strand, 12-strand and multi-strand twisted cables. The diameter of 3-strand cables is generally 4 to 50 mm, and the diameter of 8-strand cables is generally 35 to 120 mm. These ropes not only used for ship moorings, chemical fiber cables are also widely used in transportation, industry, mining, sports and fishing.
8 shares are commonly used in conventional ships. The service life of a mooring rope is usually related to the material of the rope, the braiding method, the degree of wear and the status of use. Usually the service life is 1-3 years. For the aging mooring rope we must inspect and exchange reliable mooring rope.
Difference materials rope have quite different tensile strength and wear resistance. For example, polypropylene ropes achieve high tensile strength. If you are worried that the mooring ropes get excessive wear when dragging, you can cover a protective sheath on the rope.
The rope protecting sheath is made of polyester to increase its wear resistance. Its a very wear-resistant polyester. In this way, the service life of the ship rope can be greatly extended, and the service life can generally be extended by 12 months.
