Net Type Boat Docking Pneumatic Yokohama Rubber Fender
Product Introduction:
Yokohama rubber fender which is made of synthetic-cord-reinforced rubber sheet with compressed air inside, at initial pressure of 50 kPa or 80 kPa, to enable it to float on the water and work as a shock absorber between two ships, or between ships and berthing structures when they come alongside each other on the water
1. Outer rubber
Rubber layer that covers the outside of the fender to protect the
cord layers and the inner liner rubber from abrasion and other
external forces
2. Inner rubber
Liner of a rubber membrane that seals the pressurized air inside
the fender
3. Synthetic-tyre-cord layer for reinforcement
Layer made of synthetic-tyre-cord fabric, which maintains the
internal air pressure of the fender
Note 1 to entry: As the main fibres of the synthetic-tyre-cord
fabric are not braided like synthetic canvas fabric or synthetic
belt fabric, there are advantages for its fatigue-resistance
performance and pressure-holding performance. .
4. Flange opening
Steel flange which is mounted on the fender, to which an air valve
or safety valve can be adapted
5. Guaranteed energy absorption
Energy that the fender can absorb without permanent deformation or
failure
6. Reaction force
Force produced by a fender reacting to a compressive force
Note : It is equal to the force of the air pressure of the fender
multiplied by the contact area of the fender to the ship or
berthing structure.
7. Initial internal pressure
Air pressure at which an uncompressed fender operates
8. Endurable pressure
inner pressure at which a fender bursts
Specificaton of Yokohama Rubber Fender:
Initial internal pressure : 50kPa or 80kPa.
