Sling Type  Dock Ship Yokohama Fender Pneumatic Fenders with ISO9001, BV, CCS, RS, IRS, ABS,etc Certificate

The Sling Type Fender is a lightweight and convenient derivative of the inflatable fender. Its core feature is that it uses a dedicated high-strength sling instead of traditional chains or frames for lifting and fixation. It is mainly designed for flexible deployment, quick installation, and compatibility with small and medium-sized vessels or temporary berths.

Product Description:

Material Advantages:

The main material is synthetic rubber (such as a blend of natural rubber and styrene-butadiene rubber), which has excellent elasticity and can efficiently absorb the energy of a ship impact.

The rubber material is resistant to seawater, ultraviolet radiation, and acid and alkali corrosion, making it suitable for harsh marine environments.

The internal structure uses high-strength nylon cord fabric as a reinforcing layer, improving tensile strength and tear resistance, and extending service life.

High energy absorption + low reaction force, dual protection: The energy absorption rate reaches 70%-90%, much higher than the 40%-60% of traditional protective planks; under the same impact force, the reaction force on the ship and the dock is only 1/3-1/5 of that of rigid protective planks, which can significantly reduce the risks of hull concave deformation, dock cracks, etc., especially suitable for high-value ships such as luxury cruise ships and LNG vessels.
Excellent elasticity, strong deformation recovery ability: It disperses impact energy through gas compression, can undergo significant deformation and quickly return to its original state, and its performance does not decrease when compressed at an angle, avoiding local stress concentration, and is suitable for the multi-directional swaying of ships caused by wind and waves.
Adjustable air pressure, wide adaptability: It can be adjusted to adapt to different tonnage, speed of ships and complex sea conditions (such as tidal changes), and even integrate pressure sensors and automatic inflation systems to improve berthing efficiency.
Deployment and operation advantages
Lightweight, easy installation and transportation: The weight is much lower than that of solid protective planks of the same size, and the volume is significantly reduced after deflation, which is convenient for transportation, storage and rapid deployment, suitable for temporary docks, offshore floating platforms and other scenarios, and can be modularly combined to cover longer shorelines.
Self-floating design, adaptable to water level changes: It can float on the water surface, automatically adjust its height with the tide, and does not need frequent adjustment of installation positions, suitable for ports with large tidal differences and ship-to-ship operations.

Manufacturing Process:

Raw material preparation: Rubber compounding (mixing rubber, reinforcing agents, antioxidants, etc. according to the formula), cord fabric cutting and pretreatment.

Molding process: Utilizing a winding process, the rubber layer and cord fabric are alternately wound to ensure a uniform and tight structure.

Vulcanization treatment: Vulcanization under high temperature and pressure ensures a strong bond between the rubber and the cord fabric, improving product stability and durability.

Assembly and inspection: Installing inflation valves, flanges, and other accessories; conducting airtightness tests, pressure tests, and visual inspections.

Features:

Lightweight hoisting, high installation efficiency
Equipped with customized high-strength polyester or nylon slings, the slings are integrated and vulcanized with the hull body, with an tensile strength of 10 - 20 tons. No additional welding or assembly fixings are required. Installation can be completed by a single person with a small crane. Compared to chain-fixed coamings, the installation time is shortened by more than 60%. Suitable for temporary docks, fishing ports, small yacht clubs, etc., for rapid deployment.
Low-damage design, protecting the hull and coamings
The sling material is soft and evenly stressed, avoiding rigid friction between the chain and the hull or the surface of the coaming. It can effectively prevent scratches on the hull coating and wear and cracking of the coaming rubber. Especially suitable for ships with high requirements for hull appearance, such as yachts and fiberglass fishing vessels. At the same time, the flexible connection of the sling can buffer the lateral tension caused by wind and waves, reducing the risk of coaming detachment.
Suitable for small-tonnage vessels, precise buffering performance
The volume and specifications are mainly small (diameter 0.5 - 2m, length 1 - 4m), with a wide adjustable air pressure range (0.02 - 0.15MPa), specifically meeting the berthing needs of vessels ranging from 500 to 5000 tons. The energy absorption rate can reach 75% - 85%, with low reactive force, avoiding ship displacement or deformation due to excessive counterforce from the coaming for small-tonnage vessels.
Convenient transportation and storage, outstanding cost performance
After deflation, the volume can be compressed to 1/10 of the original size. No need for large transportation vehicles, small storage space occupation, and logistics costs reduced by more than 30%. Daily maintenance only requires checking the wear of the sling and the airtightness of the coaming. Local damage can be repaired with patches on site. The total life cycle cost is lower than that of the same-sized solid coamings.
Weather-resistant and corrosion-resistant, strong environmental adaptability
The hull body is made of chloroprene rubber (CR) or ethylene propylene diene monomer rubber (IIR), resistant to seawater corrosion and UV aging, with a service life of 8 - 15 years in salt spray, high and low temperature (-30℃~+60℃) environments.
The slings are treated with UV protection and seawater immersion prevention, with long-term stable tensile performance , suitable for various water areas such as coastal and inland rivers.
Flexible combination, highly expandable
Can be used alone or connected by slings to multiple coamings to form a continuous buffering belt, meeting the protection needs of longer berths or irregular berths； combined with anti-collision tires or buffers, it can further enhance puncture resistance, suitable for complex operation environments such as sandstone docks.
