Bungee dock lines for boats
In the dock environment, ropes are exposed to seawater, moisture, salt spray, and industrial oil pollution for a long time. Traditional metal ropes (such as steel wire ropes) are prone to corrosion and failure, while PE material dock ropes have extremely strong corrosion resistance. The density of PE material is only 0.97g/cm ³, which is lighter than water and can float on the water surface. This is its core advantage compared to nylon (which becomes heavier after absorbing water) and steel wire ropes (submerged in water): if the rope accidentally falls into the water during dock operations, there is no need to dive and salvage, making it easy to recover and operate; PE material has stable chemical properties and is not prone to producing toxic substances after disposal, with minimal impact on the marine environment. The dock rope needs to frequently rub against hard objects such as dock piles, ship decks, pulleys, etc. during use, and may even come into contact with sharp objects (such as metal corners). High quality dock ropes use fiber weaving technology to increase surface density or add wear-resistant coatings to reduce friction losses. The dock rope, with its high strength, corrosion resistance, wear resistance, flexibility, ease of operation, and cushioning and shock absorption, is perfectly adapted to the complex working environment of the dock. It can ensure the stability and safety of ship mooring, reduce maintenance costs and labor intensity, and is an indispensable key equipment in modern port operations.
