Features of Pneumatic Rubber Fender
1. Guaranteed energy absorption
2. Chain tyre net and sling type
3. Thick skin construction
4. Good angular performance
5. Less surface pressure onto the side wall of ships. (The capability of accepting surface pressure of the fender is up to 14 ton/m2).
6. No reduction on the performance of compression when inclined.
7. Suitable for areas with large or small tides.
8. Suitable in cold weather because the compressed air as buffering medium.
9. Especially in mooring of large scale ships in sea docks and lightering.
10. Maintains large clearances between hull and structure
