Product Description
Floating pneumatic rubber fenders, also known as Yokohama fenders or Yokohama-type pneumatic fenders, are constructed from synthetic-cord-reinforced rubber sheets with compressed air inside. The internal air enables flotation on water and serves as a shock absorber between ships (ship-to-ship) or between ships and berthing structures. All Doowin Marine Yokohama-type floating pneumatic rubber fenders are manufactured and tested in full compliance with ISO 17357.
Our Pneumatic Rubber Fenders are available in two common types:
- Type I - Net Type: Covered with a chain net, wire net, or fiber net for small size fenders
- Type II - Sling Type: Features a lifting device on each end for connection with guy chains or ropes. Lightweight and easy to handle without a protection net
Floating pneumatic rubber fenders consist of an outer rubber layer, reinforcement synthetic-tire-cord layer, and inner rubber, all vulcanized firmly together.
- Outer Rubber Layer: Provides superior protection for cord layers and inner rubber, with compounds offering excellent tensile and tear resistance for harsh weather conditions.
- High Quality Synthetic-Tyre-Cord Layer: Maintains internal air pressure while the inner rubber layer seals the pressurized air.
- Safety Valve: Standard on fenders ≥2500mm diameter (optional for smaller sizes) to release excess internal pressure.
- Chain and Tire Net Protection: External chain and tire net (using truck, fiber, or aircraft tires) provide additional protection with easy replacement.
All materials comply with ISO 17357:2014 standards. Contact us for detailed outer and inner rubber material properties.
