Pneumatic Rubber Fender has been used for almost 50 years, it's
also called marine rubber fender or YOKOHAMA fenders.
It is the mian anticollision device for ship application in the
world.
Pneumatic Rubber Fender is used as a protective medium for ship to
ship contact, ship to quay,and ship-to-berthing.
Pneumatic Rubber Fenders are a type of marine equipments that are
used to prevent boats, ships and other naval vessels from colliding
against each other or against docks, wharves and piers. In other
words ship fenders can be simply termed as a marine bumper.
The advantages of pneumatic rubber fender
1.1 Choose reinforce synthetic-tire-cord layers
1.2 No mold vulcanization and attach surrounding molding process
1.3 High energy absorption and low reaction force
1.4 Good adaptability to tilt in contact
1.5 Floating on the surface of the water, ship swaying can apply
Structure characteristics of the pneumatic rubber fender
Pneumatic Rubber Fenders are made of an outer rubber, reinforcement
synthetic-tyre-cord layer, and inner rubber, vulcanized firmly.
A]. the outer rubbers are used to protect the cord layers and inner
rubber from abrasion and other external forces. This rubber
compound have sufficient tensile and tear resistance strength to
withstand anticipated weather conditions and severe usage.
B]. the reinforcement synthetic-tyre-cord layer strong enough to
maintain the internal air pressure of the fender.
C]. the inner rubber layer seals the pressurized air inside the
fender.
D]. fenders of diameter 2500mm and larger equipped with safety
valve for releasing excess internal pressure when the fenders are
over-compressed accidentally.
Fender assembly for the end of metal, by inside and outside the two
flanges with bolts, nut clamping, center is a valve, its structure
is similar to automobile tire valve.
The purpose of the pneumatic rubber fender
1 Ship to ship berthing
Accompanied by a large ship, the risk of two ship berthing at sea
is also increased, especially when the weather changes with wind
and waves. Adopting pneumatic fender as the buffer can not only
makes heavy berthing easy, but also improves the efficiency of the
transportation operations. Pneumatic fender is mainly used for Ice
in the Antarctic ocean fishing ships and large oil tanker
berthing.
2 Used for terminal dock protection
Because of the large size of the ship, the berthing impact energy
has multiplied.Inflatable rubber fender are widely used because
of its high energy absorption and low reaction force features.
Maintenance and safety knowledge
1 Internal pressure adjustment
Fender pressure should be kept in the standard air pressure in the±
5% range, and once every three months to check air pressure,
deflated or fill gas up to standard in a timely manner.
2 safety knowledge
a. Avoid touching the sharp things
b. when Long time not use, should wash to dry, filled with right
amount of compressed air, placed in a cool dry ventilated place.
c. Storage place away from heat, acid and alkali, oil and grease
Pneumatic rubber fender use matters needing attention
a. Pneumatic pressure control in±5% of the rated pressure
b. Test pressure normally, add pressure in a timely manner
c. Avoid contact with sharp objects
d. when Long time not need, should wash to dry, filled with right
amount of compressed air, placed in a cool dry ventilated place.
e. Storage place away from heat, acid and alkali, oil and grease
f. when store, shall not be folded and piled up
