ISO9001 Certified Pneumatic Cylindrical Robust Marine Rubber Fender with Safety Protection for Ocean Vessels and Terminals

Pneumatic rubber fenders, also known as Yokohama fenders, are manufactured from rubber and multiple layers of rubber-dipped tire fabric. These represent the leading anti-collision devices for marine applications worldwide.

Floating pneumatic rubber fenders consist of synthetic-cord-reinforced rubber sheets with compressed air inside. The internal air enables flotation on water and functions as a shock absorber between ships (ship-to-ship) or between ships and berthing structures during docking operations.

• Reinforced synthetic-tire-cord layers providing strong stability, heat resistance, fatigue resistance, and impact load resistance
• No mold vulcanization with advanced surrounding molding process
• Single-formed rubber capsule wall eliminating secondary joints and improving overall strength
• Thin, soft walls with excellent contact deformation performance and high energy absorption
• Superior adaptability to inclined contact up to 15 degrees
• Floating capability enabling application during ship swaying and multi-directional docking
• Easy installation and handling

Ships typically make initial contact with docks or other vessels at oblique angles during STS operations. Unlike solid rubber or foam fenders, which experience reduced rated reaction force and energy absorption at inclined compression, inflatable rubber fenders maintain full energy absorption capacity even at compression angles up to 15 degrees.

Ideal for ship-to-ship transfers, ship-to-berth operations, and various marine terminal applications requiring reliable collision protection.

Zhonghaihang Pneumatic Rubber Fenders are constructed with three primary components:

• Outer Rubber: Protects cord layers and inner rubber from abrasion and external forces with superior tensile and tear resistance
• Reinforcement Synthetic-Tire-Cord Layer: Maintains internal air pressure with exceptional strength and stability
• Inner Rubber Layer: Seals pressurized air inside the fender

Fenders with diameters of 2500mm and larger include safety valves to release excess internal pressure during accidental over-compression. The assembly features metal end components with dual flanges and bolt clamping, similar to automotive tire valve structures.

• Maintain fender pressure within ±5% of standard air pressure
• Check air pressure quarterly and adjust as needed
• Avoid contact with sharp objects
• During extended storage: clean, dry, fill with proper compressed air, and store in cool, dry, ventilated areas
• Keep away from heat sources, acids, alkalis, oils, and greases
• Do not fold or stack fenders during storage
