3.3 x 6.5m yokohama pneumatic fenders with internal pressure 0.05Mpa
Yokohama Fender Description:
Yokohama pneumatic Fenders which is made of synthetic-cord-reinforced rubber sheet with compressed air inside to enable it to float on the water and work as a shock absorber between two ships (ship-to-ship), or between ships and berthing structures when they come alongside each other on the water.
The yokohama fenders are kind of a cylindrical air-bag with hemispherical heads at both end. Basic body construction of this fender consists of an outer rubber layer, cord layers and inner rubber layer. All of these are vulcanized together. End flanges are at both end for convenience of air charge and other purposes.
The structure of Pneumatic Fender:
1. The outer rubber
Outside on the ball of rubber layer, which is used to protect by skeleton material and lining rubber ball from external force damage or wear.
2. Cord fabric reinforcement layer
Reinforcement layer is winded by nylon cord layer and it maintains the inner pressure of fender.
3. The inner rubber
On the ball inside the rubber layer, which is used to prevent gas leakage and stay on the ball pressure.
4. The end of the flange
On the ball at the ends of the metal parts, can be installed charging valve and relief valve.
Yokohama Fender Specifications:
Yokohama Fender utilizes compressed air as cushion medium to take in the impact energy of ship. It features favorableflexibility, powerful energy absorption,portability (lightweight) and so on,and its angular compression performance is notliable to degrade.Thus, it is widely used to help ships lighter or moor in open sea or wharf with poor berthing conditions.

Yokohama Fender Specifications and Performance
The yokohama fenders are kind of a cylindrical air-bag with hemispherical heads at both end. Basic body construction of this fender consists of an outer rubber layer, cord layers and inner rubber layer. All of these are vulcanized together. End flanges are at both end for convenience of air charge and other purposes.
Characteristics of floating Yokomama fender:
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.
4. Simple installation
The weight of floating pneumatic fenders are supported by water on which it floats, therefore, the floating
pneumatic fenders can be simply installed on the wharf and anchor mast.
Our Yokohama Fender
Our company is the leading of producing yokohama type yokohama fender in China, and all the
procedure is accorded with ISO 17357. The pneumatic rubber fender is widely used in marine shipping
industry as the protective medium against the collision when ship-to-ship and ship-to-berthing.
