Rubber Cord Marine Dock Fender With Pneumatic Type For Vessel
Docking
The Advantages of Pneumatic rubber fenders:
1 Safe for excess load.
The reaction force of floating fenders does not increase sharply
even under excess load. Therefore, these fenders perform extremely
well under such conditions and, as a result, protect ships and
mooring facilities.
2 No deterioration or Variation in performance
Because pneumatic fenders use the compressive elasticity of air,
there is no performance deterioration due to fatigue. The
performance of these fenders remains unchanged at extremely low
temperatures, even below -50℃.
3 Safety and reliability
Pneumatic rubber fenders are constructed using several layers of
strong type cord and are therefore extremely resistant to pressure
and cutting. The larger sizes (2.5m dia upward) are fitted with a
safety valve to prevent accidents in event of over compression.
4 Simply and low cost installation
The weight of the fender is supported by the water on which it
floats. Fenders can, therefore, be moored simply by means of a guy
rope or chain at minimal cost. They can be removed easily to
another position when not in use and transferred to alternative
mooring points as required.
The structure of Rubber Pneumatic Fenders:
The outer rubber layer protects the cord layer and inner layer from
abrasion and other external forces. This compound has sufficient
tensile and tear strength to withstand any weather condition and
hard usage
The cord layers are arranged at ideal angles to hold the internal
pressure and to distribute the stress evenly. The fenders cord
layer is constructed by means of integrative twine technology and
consists of polyamide fiber with high tensile stress, so that the
fenders have unique strength and uniformity in different
directions.
The inner rubber layer seals the air inside, utilizing a compound
with airtight quality.Pneumatic Rubber fender description Yokohama
rubber fender is intended to be used for the berthing and mooring
of a ship to another ship or berthing structure. It also specifies
the test and inspection procedures for high-pressure floating
Pneumatic Rubber Fender.
Flange opening:The metal parts at both ends of fender,to which an
air valve or safety valve can be adapted.
