Rubber fender is installed on wharf or ship to absorb collision energy between ship and dock or ship when landing or mooring, and protect ship and wharf from damage.

In general, rubber fenders can be divided into two categories according to their structures: solid rubber fender (non floating type) and floating rubber fender.

Solid rubber fender (non floating type) is an anti collision equipment for Wharf ships which has been used for a long time and has wide application. According to the force of rubber fender, it can be divided into shear type, rotary type and compression type. According to the structure of fender, the solid rubber fender can be divided into D, cone, drum type, fan-shaped, rectangular, cylindrical fender and so on.

Floating rubber fender can float freely on the surface of the water. According to its internal buffer medium, it can be divided into inflatable rubber fender and filled rubber fender.

Inflatable rubber fender uses compressed air as the medium and uses compressed air to do the work to consume the collision energy;

Foam filled fender is also called solid polyurethane fender, and its internal buffer medium is mainly closed cell foaming material, such as foaming EVA, foaming polyurethane and foaming rubber, etc.

Solid rubber fender has high energy absorption and reaction force, and has the advantages of low cost, long service life, simple installation and maintenance. It is a protective device installed in dock and dock.

Floating rubber fender is a new type of fender equipment, compared with the solid rubber fender, its main characteristics are: large compression deformation, large energy absorption, small counterforce, self floating, easy installation, etc. It is usually used in ship to ship, ship to wharf barge, berthing and other occasions; because of its self floating characteristics, it is especially suitable for installation of wharf with large tidal level variation. The filling rubber fender is especially suitable for harsh environment applications, such as offshore drilling platforms, because of its advantages of maintenance free and long life.
