From cotton and hemp to nylon, aramid, and polymers, different materials and processes determine the differences in strength, elongation, corrosion resistance, and wear resistance of ropes. To ensure the safe and effective use of ropes in safety, marine, military, mooring, firefighting, mountaineering, off-road and other fields, reasonable selection should be made based on the characteristics and safety requirements of the ropes, following usage standards, and paying attention to non-standard use of ropes. The following provides a detailed explanation of the types and uses of commonly used ropes based on different fields.Climbing ropeClimbing ropes are important equipment in mountaineering, with the core being climbing techniques such as lifting, reducing, and protecting. The performance and charging time of climbing ropes are three very important performance parameters.Climbing ropeModern climbing ropes are all used to add a layer of mesh rope to a few twisted ropes, rather than regular nylon ropes. Flower rope is a power rope with a ductility of less than 8%. Power rope * * * is used for projects that may experience power falls, such as rock climbing, mountaineering, reduction, etc. Generally speaking, white rope is a static rope with a ductility of less than 1% or considered as zero ductility under ideal conditions. Generally used for cave exploration, road repair ropes, and industrial purposes during mountaineering.Not all climbing ropes can be used separately. The word UIAA ① marked on the rope head can be used separately in areas that are not too steep, with a diameter of 8mm up and down. It only indicates that the strength of the UIAA rope is not enough, and only double ropes can be used at the same time.Off road series trailer ropeThe off-road series usually includes off-road trailer ropes, off-road winch ropes, and off-road soft shackles. The trailer rope is generally made of polyester nylon with a two-layer woven structure, which is sturdy and wear-resistant; The off-road winch rope can be used for off-road vehicles equipped with electric winches for off-road self rescue. The material is * * * molecular weight polyethylene; The soft shackle is made of * * * molecular weight polyethylene fiber and is used to connect the trailer rope to the vehicle body.Mooring ropeMooring line is an important part of mooring system, which is used to fix the ship to ensure that it can effectively resist the impact of wind, flow and tidal force under standard environmental conditions during berthing. The accident hazards caused by the breakage of mooring ropes under stress conditions are serious, therefore the requirements for the stiffness, bending fatigue resistance, corrosion resistance, elongation, etc. of the ropes are strict.***Molecular weight polyethylene rope is the choice for mooring cables. At the same strength, the weight is 1/7 of traditional steel wire rope and can float in water. Diversified structures and rope coatings can be used to improve the performance of cables in expected applications. In practical applications, cable breakage caused by natural factors or improper human operation cannot be ignored, which may cause serious personal injury and equipment damage.The safe operation of mooring ropes should include but not be limited to the following aspects: selecting cables based on the design breaking force of the ship, so that each rope is at an appropriate stress position; Pay attention to the maintenance of ropes and regularly check the condition of cables; Timely correct mooring cable plans based on climate and sea conditions; Cultivate safety awareness among crew members.

In addition to light weight, high strength, good impact resistance and wear resistance, ship ropes have advantages such as corrosion resistance, mold resistance, and insect resistance. If the strength and wear resistance of nylon cables exceed that of hemp and cotton cables several times, and the specific gravity of polypropylene cables is less than that of water, they can float on the water surface, making operation convenient and safe. Chemical fiber ropes are divided into two types according to their processing structure: 3-strand, multi-strand twisted ropes, and 8-strand, multi-strand braided ropes. The diameter of a 3-strand cable is generally 4-50 millimeters, while the diameter of an 8-strand cable is generally 35-120 millimeters. In addition to being used for mooring ships, chemical fiber ropes are also widely used in transportation, industry, mining, sports, and fishing.

1. TransportationPrevent rain, moisture, and sharp tool handling during transportation2. Storage in rolls (circular)The right twist rope should be coiled in a clockwise direction into a coil: the left twist rope should be coiled in a counterclockwise direction into a coil, and the cables should be placed in sequence. Move each layer of cable a few centimeters to form a spiral shape without stacking each layer on top of each other for storage.3. 8-character storage4. When the cable is exposed to ultraviolet radiation for a long time, its strength will decrease. Therefore, after use, the cable should be placed in a backlit area to prevent direct sunlight, so as not to affect the strength and service life of the cable5. The cable shall not be operated in molten metal, acid, alkali corrosion, nuclear reactor and high temperature environment.6. If users want to use a certain type of cable under special conditions, they should consult with the production factory for technical assistance.

High performance ultra-high molecular weight polyethylene cables produced by introducing overseas equipment and technology, using high-quality ultra-high molecular weight polyethylene fibers, with a structure of three strands, eight strands, twelve strands, and other specifications φ 6MM-160MM, the product has ultra-high strength, lightweight, low elongation, wear resistance, smooth and soft, anti-corrosion and aging resistance, more convenient, faster, and safer operation, and is often used for port towing, VLCC, VLCC, VLOC mooring, national defense and military equipment, naval equipment, marine engineering, aerospace, sports equipment, power communication, Large precision object lifting and other fields.
