Tire Chain Net Protective Marine Fender

SunKai Tire Chain Net Protective Marine Fender provides customized marine protection solutions for vessel berthing applications. The fender combines an airtight pneumatic rubber body with an external tire chain net protective structure, creating a flexible impact protection system for ship-to-ship transfer, terminals, and dockside operations.

The internal compressed air absorbs berthing impact through controlled compression, reducing reaction force and surface pressure on vessels and dock structures. The external tire chain net uses rubber tires connected with high-strength chains to improve wear resistance, distribute impact forces, and protect the pneumatic body from sharp contact surfaces.

The fender body consists of an inner airtight rubber layer, multiple high-strength cord reinforcement layers, and an abrasion-resistant outer rubber layer. Manufactured through integrated wrapping and high-temperature vulcanization, the structure provides reliable airtight performance and long-term durability.

Available in 50 kPa and 80 kPa pressure grades, SunKai Tire Chain Net Protective Marine Fender can be customized according to vessel size, berthing energy requirements, and installation conditions.

Tire Chain Net Protective Structure

The main feature of SunKai Tire Chain Net Protective Marine Fender is the external tire chain net protection system.

The tire chain net fully surrounds the pneumatic rubber body and works as a protective layer between the fender surface and external contact points. During vessel berthing, the tire and chain structure helps distribute impact pressure over a wider area, reducing concentrated stress on the rubber surface.

This protective structure helps:

· Reduce local wear on the pneumatic rubber body

· Protect against steel structures, concrete edges, and rough contact surfaces

· Improve resistance to repeated berthing impact

· Extend the service life of the marine fender

The chain components are treated with anti-corrosion protection to improve durability in seawater and salt spray environments.

Pneumatic Cushioning Performance

SunKai Tire Chain Net Protective Marine Fender uses compressed air as the cushioning medium.

When a vessel contacts the fender, the internal air chamber compresses gradually and absorbs impact energy. The pneumatic structure provides a softer contact process compared with conventional solid rubber fenders, helping reduce reaction force and hull pressure.

Main performance benefits include:

· High energy absorption capacity

· Lower reaction force

· Reduced contact pressure on vessels and docks

· Stable compression performance under different berthing angles

The fender maintains effective protection even during inclined compression and different vessel approach directions.

Technical Specifications

Note: The above are standard conventional dimensions. SunKai can customize the dimension specifications and performance parameters of Tire Chain Net Protective Marine Fenders according to customer actual project requirements.

Multi-Layer Cord Reinforced Manufacturing

SunKai Tire Chain Net Protective Marine Fender is manufactured using a multi-layer reinforced rubber structure, including:

· Inner airtight rubber layer

· Multiple synthetic cord reinforcement layers

· Outer wear-resistant rubber layer

The rubber body adopts integrated wrapping and high-temperature vulcanization technology. The seamless construction reduces potential leakage points and improves structural reliability during long-term marine operation.

Each fender is inspected for:

· Rubber material quality

· Reinforcement layer arrangement

· Vulcanization condition

· Airtight performance

· Tire chain net installation quality

Performance Characteristics

High Energy Absorption with Low Reaction Force

Relying on the high-efficiency pneumatic cushioning structure, the fender can absorb large berthing impact energy while maintaining a low and stable reaction force, effectively reducing the impact load transmitted to vessel hulls and dock infrastructure.

Reduced Hull and Dock Surface Pressure

The flexible pneumatic contact surface realizes soft contact during vessel berthing, avoiding rigid extrusion and pressure concentration. It comprehensively protects ship coating systems, hull structures, dock walls and marine terminal supporting equipment.

Enhanced Abrasion and Impact Resistance

The external tire chain net isolates the rubber body from direct friction and collision with external hard surfaces. It is specially suitable for ports and terminals with frequent berthing operations and harsh marine working environments.

Marine Environment Durability

The combined protection of marine-grade rubber, high-strength cord layers and anti-corrosion tire chain net enables the fender to resist various marine environmental damages:

• Seawater long-term immersion erosion

• Salt spray corrosion and atmospheric aging

• Frequent mechanical friction and impact

• Cyclic impact load fatigue damage

Installation and Maintenance

Before Installation

Inspect the following items to ensure normal equipment operation:

• Surface integrity of pneumatic rubber body

• Overall condition of tire chain net (no deformation, damage or loose links)

• Firmness of chain connections and supporting fittings

• Air valve sealing and working condition

During Operation

• Maintain the standard rated internal pressure of the fender

• Avoid contact with sharp hard objects to prevent rubber piercing and scratching

• Check internal air pressure regularly to ensure stable cushioning performance

• Periodically inspect tire chain net connections for looseness or wear

After Operation & Storage

• Flush surface seawater and salt deposits with clean fresh water

• Dry the fender completely before storage

• Keep away from oil, organic solvents and corrosive chemicals

• Store in a dry, ventilated and clean environment

Minor rubber surface damage can be repaired with special rubber repair materials; professional maintenance is recommended for structural damage, reinforcement layer failure or air leakage problems.

Frequently Asked Questions

What is the difference between Tire Chain Net Protective Marine Fender and conventional pneumatic fenders?
Different from conventional pneumatic fenders that only rely on the rubber body for protection, this fender adds a full-coverage tire chain net protective layer. It can effectively disperse berthing impact loads, improve overall abrasion resistance, and avoid direct damage to the rubber body during repeated vessel contact. The internal pneumatic chamber still undertakes the core energy absorption and cushioning function.

Does the tire chain net affect energy absorption performance?
No. The energy absorption and cushioning performance of the fender is determined by the internal pneumatic structure and air pressure grade. The tire chain net only serves as an external protective structure, which optimizes force dispersion and anti-wear performance without weakening the original cushioning and energy absorption characteristics of the pneumatic fender.

How to choose between 50 kPa and 80 kPa pressure grades?
The selection depends on vessel size, berthing speed, berthing energy and required reaction force. The 50 kPa grade features softer cushioning and lower reaction force, suitable for medium and small vessels and scenarios requiring low hull pressure. The 80 kPa grade provides higher energy absorption capacity, ideal for large heavy-tonnage vessels and high-load berthing conditions. The final selection shall comprehensively consider vessel weight, berth design and actual working conditions.

Can SunKai customize Tire Chain Net Protective Marine Fenders?
Yes. We provide full personalized customization services, including fender diameter, length, internal pressure grade, tire chain net specifications and supporting connection accessories. All products can be tailored to meet customer project requirements and on-site working conditions.
