UHMWPE Rope  Double Braided HMPE Port Towing Ship Super Mooring System Rope

1. General Description

QINGDAO JINCHENG MARITIME has serial products including varieties of nylon, polypropylene filament, polypropylene, polypropylene /polyester mixed, polyester. It started a new epoch of rope and cable industry in the country and its products have advantages of reasonable braided structure, scientific technology, high strength, low elongation,wearing resistance, anti-corrosion and simple operation, it is particularly suitable to make large scale ropes and cables as well as anti -static ropes therefore they are well received by broad customers, The products are mainly used in fields of shipbuilding, ocean transportation, national defense and military industry, sea petroleum and harbor operation etc.

1. Features

• Exceptional Strength-to-Weight Ratio: The 8-strand double braided construction combines an inner core and an outer braid, both made of high-tensile fibers. This design distributes load evenly across all strands, resulting in a rope that offers significantly higher breaking strength compared to single-braided or twisted ropes of the same weight and diameter. It is easy to handle and transport without sacrificing durability.
• Superior Flexibility and Knot Retention: The double braided structure, with 8 outer strands, gives the rope excellent flexibility. It can bend and conform to various shapes easily, making it simple to tie and untie knots. Moreover, the tight braiding ensures that knots stay secure once tied, reducing the risk of slippage even under dynamic loads, which is crucial for tasks requiring reliable knot performance.
• Abrasion Resistance: The outer 8-strand braid acts as a protective layer for the inner core. This outer layer is tightly woven, creating a smooth yet tough surface that can withstand friction against rough surfaces such as rocks, metal, or wood. It minimizes wear and tear on the inner core, extending the overall service life of the rope, especially in harsh operating environments.
• Low Stretch and High Elasticity Balance: This type of rope maintains a good balance between low stretch and moderate elasticity. It has minimal elongation under static loads, ensuring precise positioning and control in applications like lifting or mooring. At the same time, it possesses a certain degree of elasticity to absorb shock loads (e.g., sudden pulls or impacts), reducing the risk of rope damage or equipment failure caused by abrupt forces.
• Weather and Chemical Resistance: When made from synthetic fibers (such as polyester or nylon), the 8-strand double braided rope exhibits strong resistance to environmental factors. It is resistant to UV radiation, preventing degradation from prolonged sun exposure; it also repels water, avoiding water absorption that can add weight and cause rot (unlike natural fiber ropes). Additionally, it can withstand exposure to common chemicals, oils, and saltwater, making it suitable for both indoor and outdoor, as well as marine, applications.

2. Applications

• Marine and Boating: It is widely used in marine settings, such as mooring lines (to secure boats to docks), dock lines, and anchor lines. Its abrasion resistance stands up to contact with boat hulls and dock edges, while its water resistance and saltwater tolerance prevent deterioration in marine environments. The high strength ensures it can handle the forces of waves and wind.
• Recreation and Adventure: In outdoor activities like rock climbing, caving, and rappelling, this rope is a reliable choice. Its strength-to-weight ratio makes it easy for climbers to carry, and its knot retention ensures safe belaying and rappelling. It is also used in camping for setting up tents, hanging food bags, or creating zip lines in controlled adventure parks.
• Industrial Lifting and Rigging: In industrial environments, it is employed for light to medium-duty lifting and rigging tasks. For example, it is used to hoist small machinery, tools, or materials in factories, construction sites, or warehouses. Its low stretch ensures accurate positioning of loads, and its flexibility allows it to be routed around pulleys and hooks easily. It is a safer alternative to some metal cables in situations where accidental contact with workers could cause injury.
• Arboriculture (Tree Care): Arborists use this rope for various tree care tasks, such as climbing trees to prune branches, remove deadwood, or install tree supports. Its strength supports the weight of arborists and their equipment, while its flexibility allows it to be maneuvered through tree canopies. The abrasion resistance protects the rope from damage caused by contact with tree bark, branches, or rough terrain on the ground.
• Utility and Maintenance Work: It is used in utility work, such as for securing ladders or scaffolding during maintenance of buildings, power lines, or telecommunication towers. It can also be used as a tag line to guide and stabilize materials being lifted to heights, ensuring they do not swing uncontrollably. Its weather resistance makes it suitable for outdoor utility projects, where it may be exposed to rain, sun, or extreme temperatures for extended periods.
