Edit: Jiangsu Ahn Jin Rubber Co., Ltd.Date: 2018-09-04

In the rubber fender industry, no matter the model or style, there are dozens of kinds. In the dock construction, according to the site conditions and design requirements of the dock, what type of rubber fender should we choose, and the construction drawings Consistent. Below we recommend the top ten rubber fenders and models commonly used in dock or bridge construction.

First, the cone type ramp ZC

TD-AA tapered rubber fender is the third generation of drum rubber fender. It adopts a new structural design of cone rubber body and front steel frame, so that the fender can be designed to compress deformation without increasing the reaction force. With an increase of 52.5% to 70%, it is one of the best rubber fenders available today. Its emergence makes the dock structure design lighter and reduces the cost of the terminal construction. It is an ideal substitute for super drum rubber fenders .

TD-AA conical rubber fender is the third generation product of drum type rubber fender. It adopts a new structural design of cone rubber body and front steel frame to increase the design deformation deformation from 52.5 to 70 without increasing reflexes. , Become one of the Best rubber fenders today. Its appearance can make the structure design of the pier lighter and reduce the cost of the dock project. It is an ideal alternative to the Super drum rubber fenders.

Tapered rubber fenders have been around for a decade since their introduction, and the design of tapered rubber fenders has become a new trend in today's wharf design, representing a new level of design for wharf fenders.

1. Compared with super rubber fenders of the same specification, the energy absorption is nearly doubled.

2. In the case of similar reaction force and energy absorption, the small-size TD-AA cone rubber fender can be used instead of the larger TD-A super drum rubber fender, and the TD-AA800H cone fender can be used. Replace the TD-A1000H rubber fender to reduce the cost of the terminal construction.

Second, the super drum type SC

1. Increase in energy absorption / reaction force

The SC super drum rubber fender has an E/RH value of approximately 15% compared to a conventional drum rubber fender. The E/RH value of the conventional drum rubber fender is generally 0.375 to 0.385, while the SC super drum rubber guard The E/RH value of the shipboard is generally 0.43~0.44.

2. The structure is more reasonable

SC super drum rubber fender, the structure is more reasonable than ordinary rubber fenders , and the connection between the fender body and the flange is excessively smooth, which reduces the stress concentration of the root of the fender during compression deformation. The load on the side is more reasonable and the amount of compression on the fender is increased from 47.5% of the normal type to 52.5%.

3.SC Super drum rubber fenders have the same mounting bolt pitch and bolt holes as ordinary rubber fenders .

4. It has the characteristics of small inclination and berthing effect.

Third, D-type rubber fender

1. Counterforce and energy absorption

2. The bottom width is moderate, the special applies to the box terminal

3. Light weight, easy installation and maintenance.

English translation:

Inverse force

2. Moderate bottom width, special envoy applies to the box pier

3. Light weight, easy to install and maintain.

Fourth, GD rubber

Features: 1. High energy absorption and large reaction force;

2, the bottom width is small, especially suitable for framed docks;

3. High installation strength and long service life.

Inverse force

2. Moderate bottom width, special envoy applies to the box pier

3. Light weight, easy to install and maintain.

5. Cylindrical (Y) rubber fender


1. Low reaction force, small surface pressure and reasonable energy absorption

2. Adaptability to roll and pitch when the ship is berthing

3. Wide application range, can also be used as ship anti-collision device

Low reflexes, small face pressure, reasonable energy absorption

2. Strong adaptability to the rolling and rolling when ships when berthing

3. It can be widely applied and can also be used as a collision prevention device for ships.

4. Easy installation and maintenance

Sixth, V-shaped rubber fender

Features: 1. The reaction force is moderate and the energy absorption is high. 2. The installation is firm and easy to disassemble. 3. Suitable for medium-sized terminals.

Seven, π-type rubber fender

1. The top of the fender has a large area and the contact surface pressure is small;

2, high energy absorption, low reaction force, suitable for terminals above 10,000 tons;

3. The span between the two support arms can be adjusted and the compression deformation can reach 52.5%;

4. The outer surface of the anti-shock plate is ultra-high polymer polyethylene plate or nylon, and its friction coefficient is small;

5, can be installed vertically or horizontally, no need to be equipped with supporting anchor chain.

Eight, turning the fender

Rotating rubber fenders use the rotation and compression deformation (rubber) of the roller to absorb the impact energy of the ship. When the ship is berthing or moving, the rotating fender can adapt to the movement of the hull and rotate, thus ensuring the safety of the wharf and the ship. Rotating fenders are suitable for use in shipyards, docks, ro-ro ship docks, wharf corners and where it is required to limit the direction of movement and berthing speed of the ship.


a. The fender (roller) rotates on the three axes, which can limit and reduce the running speed of the ship, which is beneficial to the safe berthing of the ship;

b. The compression deformation can reach 40%, which is more than double the energy of the traditional rotating fender;

c. Since the rotating fender can adapt to the movement of the hull, the hull and the rubber fender do not produce sliding friction, so it is not easy to damage the hull paint.

Nine, rubber ramp

1. Both rubber fender and gangway function, more durable than steel gangway

2. No need to hide the ladder, install the same as the rubber fender

3. Not afraid of collision, no rust, the ladder column has bendability

4. Easy to install and maintain

X. Cape angle rubber fender

These are the top ten rubber fenders in common projects, as well as non-standard rubber fenders that require special design and customization, such as wrap rubber fenders . If some companies need to customize the map, please contact the Anjin Rubber Fender Company.
