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.
