Docking ship yokohama type high energy absorption Low Reaction Marine Pneumatic Fender
Pneumatic Large Ship Fender is the advanced anti-collision device for marine application in the world. Pneumatic rubber fender is also known as floating fender or Yokohama type tugboat rubber fender, it is often installed on the terminal or ship, which aims to absorb or reduce the collision energy between ship to ship and ship to dock. This kind of product can protect the ship or dock from the damage of collision. With inner compressed air, it can float on the water and widely used as protecting medium equipment. Size : D0.5 m x L1.0 m ~ D 3.3 x L6.5m. “XINCHENG” yokohama barco defensas are produced in strict accordance with the ISO17357-2002 and GB/T 2002-2002 international quality standard. Nowadays, our products have been exported to all over the world.
Advantages low reaction marine pneumatic fender:
1. Large compression deformation, low reaction force, high energy absorption
2. Good floating performance, meet the needs of water level change
3. With compressed air as medium, the collision energy consumption bu compressed air power
4. Easy installation and long service life
Structure pneumatic tugboat fender
1. Outer Rubber
Cover outside on the ball of rubber layer, which is used to protect skeleton material and inner rubber ball from damage of external force, the main features: high strength, wear resistance, ageing resistance and tear resistance.
2. Synthetic cord reinforced rubber layer
Reinforced cord rubber layer is composed of winding Synthetic cord layer, It is mainly used for maintain the internal air pressure, which has good elasticity, no deformation and high power etc.
3. Inner Rubber
On the ball inside the rubber layer, which is used to prevent air leakage and control the ball pressure.
4. Flange opening
The metal parts at both ends of fender, which can be fitted with charging valve and safety valve.
Synthetic-tyre-cord layers commonly used in tyres, have been proved to provide strong efficient reinforcement layers in fenders. Each layer is coated with rubber compound on both sides as well as in between synthetic-tyre-cord threads, hence isolating all cords from each other.
1. Wrap threads that run vertically through the synthetic -tyre-cord pattern.
2. Weft threads that run perpendicular to the wrap threads.
