What type do we have?
Tire net type: multiple tires are tied to the ball, and both ends are tied to a special flywheel that can rotate flexibly. Suitable for large and reliable balls.
Rubber net type: tie a special rubber pad to the ball, which can be freely contracted or stretched when squeezed. Suitable for medium and small reliable balls.
Line type: The net cover is woven with nylon rope; tightly tied to the ball. It is suitable for small size reliable balls.

Pneumatic Rubber Fender Application
Pneumatic Rubber Fender is constructed of synthetic-cord-reinforced rubber sheets with compressed air inside to keep floating over the water surface and work as a shock absorber between two ships or between ships and berthing structure when they come alongside each other on the water.
Pneumatic Rubber Fender is a leading anti-collision device for marine application in the world today. Pneumatic Fender has become an idea ship protection medium used extensively by large tankers, LPG vessels, ocean platforms, large docks, harbors and wharves.

For Large-tonnage Ship |
1. When the Pneumatic rubber fender is not used for a long time, it should be washed and dried, filled with appropriate compressed air, placed in a dry, cool, ventilated place.Inventory temperature is maintained at -15 ℃ -40 ℃ .
2 .The place where the fender is stored should be kept away from the heat source.
3 .Fenders shall not be in contact with acids, alkalis, greases and organic solvents.
4 .When the fenders are not in use, they must not be stacked and should not be stacked on the ba. In order to better extend the service life of pneumatic rubber fenders, it is recommended that you store them in strict accordance with the above recommendations.
