Instruction of Yokohama D2.0L3.5m marine pneumatic rubber fender
Pneumatic rubber fender is installed on the dock or ship, to absorb the collision energy between the ship and the dock or ship when berthing or mooring, and to protect the ship and the dock from damage.
Pneumatic rubber fender has the advantages of low reaction force, small surface pressure and reasonable energy absorption. In berthing, the ship rolling and pitching adaptability, it will not affected by the size of the ship and is widely used for installation and maintenance convenient, especially suitable for the dock.
