The fender is mainly to withstand the impact force of the ship when the ship is docking, leaving the dock and other forms (such as when the ship is tied to tow), and transmits it to the hull structure of a larger area. Wooden fenders have buffering effect. Although steel fenders have poor buffering effect, they have better strength and can be included in the section of the hull girder (the welding strength must be guaranteed). Especially for large-open deck barges, they can make up for the deck The lack of effective cross-sectional area is conducive to longitudinal strength. Steel materials cannot be used for the fenders of oil barges and small oil tankers.
Large seagoing vessels usually do not have fenders. River boats, work boats, permanent double-track fenders, one of which is located on the upper deck, and the other is located slightly higher than the designed waterline
1 Outer rubber
The outer rubber layers that covers the outside of fender protects the cord layers and the inner rubber from abrasion and other external forces. This compound has sufficient tensile and tear strength to withstand any weather condition and hard usage. Standard color is black, but other colors are available on request.
2 Inner rubber
The liner of a rubber membrane seals the pressurized air inside the fenders.
3 Synthetic tire cord layers for reinforcement
The reinforcement layers, which are made of synthetic tire cord commonly used in tires, are arranged at ideal angles to hold the internal pressure and to distribute the stress evenly providing strong efficient reinforcement.
4 Beading ring
A steel ring is placed at one end (or both ends) of the fender and holds the end of cord layers.
5 Flange
A steel flange is mounted on the fender, to which an air valve or safety valve can be adapted.
6 Safety valve
Fenders of diameter 2500mm and larger shall be equipped with safety valve for releasing excess internal pressure when the fenders are over-compressed accidentally. Fender which are smaller than 2500mm in diameter, can be equipped with a safety valve if required.
7 Metal accessories
All the relevant metal accessories of pneumatic fenders, include shackles, towing rings, swivels, chain net, are made of stainless steel, which are resistant for sea water corrosion.

1. Safety and Reliability
Boat Rubber Fender are constructed of several layers of strong tire-cord, and are thus resistant to pressure and cutting. The safety factor adopted in the design of this fender is based on accepted theory and has been proven by extensive experimentation. large-size fenders are equipped with a safety valve to release the inside air in the event of accidental over-pressure.
2. No Deterioration or Variation in Performance
Boat Rubber Fender utilize the compressive elasticity of air, therefore performance deterioration due to fatigue is absent.
3. Advantages at Inclined Berthing
Boat Rubber Fender, energy absorption does not decrease at inclined compression up to 15 degrees.
4. Most Cost Competitive System
The utilization of the compressive elasticity of air provides completely uniform surface pressure on contact, making Boat Rubber Fender ideal. The surface pressure of the Boat Rubber Fender is equal to the internal air pressure. Due to low and uniform surface pressure properties, the Henger Pneumatic Rubber Fenders are popular at LNG-ship terminals.
5. Soft Reaction Force for Ship and Jetty Structure
The reaction force of Henger Pneumatic Rubber Fenders does not increase sharply, even under excess load conditions. Therefore, the Boat Rubber Fender perform well in such cases, and protect ships and mooring facilities.
6. Lower Mooring Forces under Rough Weather Conditions
The reaction force and deflection of Boat Rubber Fender do not easily reach the maximum because the reaction force increases slowly and allowable deflection is wide. Thus, the Henger Pneumatic Rubber Fenders safely protect ships and mooring facilities even under rough weather.
