Chain Tyre Net Yokohama Pneumatic Fender
Pneumatic fender is a prevailing style of anti-collision device for marine use in the word of today. When the ship contacts to ship or berthing facilities, its protective effect against collision is better than that of conventional fenders made of solid rubber fender, etc.
These fenders are generally equipped with chain nets and tyres or with wire rope nets, end rings, towing rings and swivel joints with suitable D-Shackles at both ends for better life. Sling type fenders are also available on specific request. These fenders offer excellent resistance to shear force, inclined compression and are highly reliable.
Characteristics
1. Safety and Reliability
Using compressed air as damping medium, the rubber fender can transform flexibly under pressure, with large contact area, small reaction and absorb large amount of energy.
2. Safe for excess load
When berthing , the ship is almost at a certain angle, the pneumatic rubber fender can realize contact in a certain angle by bringing full play to its performance.
3. Adaptable to the tide
Floating on the water surface, even the ship fluctuate and sway resulting from ebb and flow and waves, the pneumatic rubber fender bears less friction, which would be no harm to coating surface of ship and rubber fender.
