Durable Yokohama Type Pneumatic Fenders Floating Rubber Fender
Yokohama Type Pneumatic Fenders
Advantages
1. Tide Adaptation
Yokohama type pneumatic fender is filled with pressure air inside that make it flexible and easy to float on the water and adapt to the tide variation.
2. Strong Enough against Shear Force
Yokohama type pneumatic fender is made of reinforced-tyre-cord layers which enable to make it cope against the shear forces and compression forces.
3. No Variation or Deformation in Performance
Yokohama type pneumatic fender is filled with air of compressive elasticity inside,the deformation caused by fatigue is absent. In the experiment of yokohama type pneumatic fender, the performance variation will not happen if the pressure is maintained properly. Our yokohama type pneumatic fender remains the same without any variation or deformation even at temperatures under -50 degrees centigrade (-58 degrees fahrenheit).

Yokohama Type Pneumatic Fenders
Yokohama type pneumatic fender is composed of inner rubber layer, outer rubber layer, and reinforced synthetic-tire-cord layer which is strong enough to withstand external compression and twisting force. Yokohama type pneumatic fenders are widely used in STS transfer operations and STD berthing protection. They’re easy to install and deflated, and adapt to the tide perfectly. Jerryborg offers various types and dimensions of Yokohama type pneumatic fenders upon customer’s request.
Fully compliant with the ISO17357 standard, Jerryborg’s Yokohama type pneumatic fender can also be equipped with chain and tire net(CTN)to provide additional protection to extend its service life.
