Product Details

Sling Type Pneumatic Fender Easy To Install , Rubber Dock Fender For Boat

marine inflatable fenders are known as Yokohama fenders or inflatable pneumatic fenders. Floating pneumatic rubber fenders is made of the synthetic-cord-reinforced rubber sheet with compressed air inside to enable it to float on the water and work as a shock absorbed between two ships (ship-to-ship), or between ships and berthing structures when they come alongside each other on the water. All Marine Yokohama type floating pneumatic rubber fenders are manufactured and tested fully compliant with ISO 17357.

Fender structure

Outer Rubber

The tough abrasion resistant outer rubber is designed to protect the inner rubber and tyre-cord layers from damaging external forces. The material has mechanical properties to withstand the arduous operational conditions for which it is designed.

The diagram below shows the actual properties as specified in ISO 17357. Generally, the outer rubber is black, but other colours such as grey and off-white can be supplied upon request.

Tyre-cord Layer

Synthetic tyre-cord layers have proven to be the best option for strong, efficient reinforcement for pneumatic rubber fenders. Each layer is coated with a rubber compound on both sides that prevents contact between the layers, reducing friction and
wear during bending, compression and stretching. The same compound isolates each thread within the layer.
This greatly improves the ability of the fender to hold pressure, fatigue resistance and endurance life. Other reinforcing layer materials such as canvas have wear points that significantly reduce the life off the fender.

Inner Rubber

The inner rubber seals pressurised air inside the fender. It is usually constructed of a compound similar to that of an inner tube in a truck or car tyre to ensure a good level of air tightness.

Sling type pneumatic fenders don`t include chain tires net, but with a specially processed outer rubber double-layered cover , resulting in better resistance to operational damage.

Sling type pneumatic fender strengths:

1, First manufacturer in China being ISO17357-1-2014 Approved

2, Light and easy to re-deploy

3, Equipped with safety valve to assure safety operation.

4, Fast delivery, common size 0.5x1,1x1.5,1x2,1.5x,2x3.5 are available in stock for immediately dispatch
