High Energy Absorption and Low Reaction Force
The fender uses compressed air as an energy-absorbing medium, allowing large deflection while maintaining a low reaction force. This feature ensures that both the vessel hull and quay remain undamaged during impact. The unique internal pressure dynamics enable superior cushioning even under heavy berthing speeds.
Reinforced Layered Structure for Maximum Strength
Each fender is constructed with multiple layers of synthetic tire-cord fabric embedded between thick rubber sheets. This design provides exceptional tensile strength, resists fatigue, and prevents tearing under repeated compression. The reinforced body distributes load evenly, extending the fender’s service life even under demanding port conditions.
Durable Outer Rubber Shell
The external layer is composed of weather-resistant, abrasion-resistant, and UV-resistant rubber compounds. It withstands harsh marine environments, including saltwater, oil, and ozone exposure. This durable cover prevents surface cracking and aging, ensuring reliable long-term performance with minimal maintenance.
Ease of Installation and Pressure Maintenance
Hongruntong pneumatic fenders are lightweight, easy to deploy, and can be adjusted by simply changing internal air pressure. Optional chain and tire nets provide additional mechanical protection. Maintenance is simple, requiring only periodic pressure checks and external inspections, significantly reducing operational downtime.

FAQ
1. How long does a Yokohama fender last?
Typically 10 to 15 years under standard operating conditions, depending on impact frequency, environment, and maintenance quality.
2. Can the fender operate in extreme weather?
Yes. The materials maintain elasticity and strength in high UV, salinity, and temperature variations from –50 °C to +70 °C.
3. How is the fender maintained?
Regularly check internal air pressure, inspect for cracks or surface damage, and clean marine growth. Maintain correct pressure for stable performance.
4. Can fenders be repaired if damaged?
Minor surface wear can be patched. Major structural or bladder damage should be serviced by Hongruntong’s repair facilities to ensure safety compliance.
5. What types of fittings are available?
Options include flanged ends, swivel eyes, chain-tire nets, or sling-type designs depending on berthing requirements and vessel size.
