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, fire fighting, mountaineering, and off-road applications, reasonable selection should be made based on the characteristics and safety requirements of the ropes, usage standards should be followed, and non-standard use of ropes should be noted. Below, the types and uses of common ropes are explained in detail according to different fields.

　　Mountaineering Rope

　　Mountaineering ropes are important equipment in mountaineering, with their core function being in ascent, descent, and protection techniques. The rope's properties and durability are three very important performance parameters.

　　Mountaineering Rope

　　Modern mountaineering ropes are all made with several strands of rope plus a mesh layer, rather than ordinary nylon rope. Dynamic ropes have less than 8% elongation. Dynamic ropes are used for activities where dynamic falls are possible, such as rock climbing, mountaineering, and rappelling. Generally, static ropes have less than 1% elongation, or are considered to have zero elongation under ideal conditions. They are generally used for cave exploration, rescue operations, and industrial purposes during mountaineering.

　　Not all mountaineering ropes can be used alone. Ropes marked with the UIAA symbol can be used alone in less steep areas, with a diameter of around 8mm. Ropes only marked with UIAA are not strong enough and must be used as a double rope.

　　Off-Road Tow Ropes

　　Off-road series typically include off-road tow ropes, off-road winch ropes, and off-road soft shackles. Tow ropes are generally made of polyester nylon with a double-braided structure, making them strong and wear-resistant; off-road winch ropes can be used on off-road vehicles equipped with electric winches for self-rescue. The material is ultra-high molecular weight polyethylene; soft shackles are made of ultra-high molecular weight polyethylene fiber and are used to connect the tow rope and the vehicle body.

　　Mooring Ropes

　　Mooring ropes are an important component of the mooring system, used to secure vessels and ensure effective resistance to wind, current, and tidal forces under standard environmental conditions during berthing. Accidents caused by mooring rope breakage under stress are serious, therefore, the requirements for rope stiffness, resistance to bending fatigue, corrosion resistance, and elongation are extremely strict.

　　Ultra-high molecular weight polyethylene rope is a choice for mooring cables. At the same strength, the weight is 1/7 that of traditional steel wire rope, and it can float on water. Diversified structures and rope coatings can be used to improve the performance of the cable in its intended application. In practical applications, cable breakage due to natural factors or improper human operation cannot be ignored, and may cause serious personal injury and equipment damage.

　　Safe operation of mooring ropes should include, but is not limited to, the following aspects: selecting cables according to the design breaking strength of the vessel, ensuring that each rope is under appropriate stress; paying attention to rope maintenance and regularly inspecting the cable condition; correcting the mooring cable plan in a timely manner according to the climate and sea conditions; and cultivating the safety awareness of the crew.
