Rubber Fender classification; Characteristics and Applications
Usually rubber fender according to the structure can be divided into two categories: solid rubber fenders (non-floating) and floating rubber fenders.
Solid rubber fender (non-floating type) is the history of the earlier application, and wide application of the anti-collision devices ship pier. The rubber fender can be divided into the forces shear, rotary type and compression type, etc.; according to fender structure, solid rubber fenders can be divided into D-type, cone, drum, fan-shaped, rectangular, cylindrical shaped fenders and so on.
Floating rubber fenders can freely float on the water surface, which can be divided according to the different internal buffer medium: inflatable rubber fenders, rubber fenders filled.
Inflatable rubber fender is a compressed air as the medium by compressed air acting to dissipate collision energy; filled rubber fenders buffer medium predominantly closed-cell foam material, such as foam EVA, foamed polyurethane and foam rubber, etc.
Characteristics and applications of rubber fenders
Solid rubber fender has a high energy absorption and reaction, along with low cost, long life, simple installation and maintenance, etc., it is piers, docks install more protection.
Floating rubber fenders fenders are newer equipment, compared with solid rubber fenders Its main features are: large compressive deformation, absorbing a large reaction force is small, self-floating, easy installation. Usually used in ship-to-ship (ship to ship), ship to dock (ship to wharf) goods under the barge, docked other occasions; because it is particularly suitable for large changes in tidal dock installation from floating characteristics. Which filled rubber fenders because of its maintenance-free, long life and other advantages are particularly suitable for use in harsh environments, such as offshore drilling platforms.
