Yokohama Dock Rubber Fender
Progress and development of ship technology, and has to continuously cope with progressively larger oil tankers such as VLCC's, ULCC's, large gas carriers, bulk carriers and floating structures.
Floating pneumatic fenders are used world wide for ship-to-ship (STS) transfer operations, terminals, and for all kinds of ships.
Since its creation until today, Henger more than 10,000 fenders have been supplied worldwide both for ship-to-ship and ship-to-dock operations serving our valuable customers.These fenders play a critical role in the safe operation of ship berthing and mooring.
What type do we have?
Tire net type: multiple tires are tied to the ball, and both ends are tied to a special flywheel that can rotate flexibly. Suitable for large and reliable balls.
Rubber net type: tie a special rubber pad to the ball, which can be freely contracted or stretched when squeezed. Suitable for medium and small reliable balls.
Line type: The net cover is woven with nylon rope; tightly tied to the ball. It is suitable for small size reliable balls.
How does the fender work?
The pneumatic fender or inflatable rubber fender or Yokohama fender compressed air is used as a buffer medium to absorb the impact energy of the ship, so that the ship has more flexibility and flexibility when docking, so as to prevent The impact of collisions and collisions.
What is Pneumatic Rubber Fender?
The "Yokohama Type Pneumatic Rubber Fender" was developed in 1958. Progress in the development of such floating pneumatic rubber fenders is closely related to the progress and development of ship technology, and has to continuously cope with progressively larger oil tankers such as VLCC's, ULCC's, large gas carriers, bulk carriers and floating structures. Floating pneumatic fenders are used world wide for ship-to-ship (STS) transfer operations, terminals, and for all kinds of ships. Since its creation until today, more than millions of fenders have been supplied worldwide both for ship-to-ship and ship-to-dock (STD) operations serving our valuable customers. These fenders play a critical role in the safe operation of ship berthing and mooring

Unique Design of Henger Pneumatic Rubber Fender
Active-Protecting Safety Valve , All fenders are equipped with a safety valve to release the inside air in the event of accidental over-pressure.
It is a patented design which could avoid explosion of fenders from collision and air inflation.
Henger Flange is casting of corrosion-resistant iron with galvanized anti-corrosive coating, which will strongly prolong the fender quality and service life. The strength of Henger casting flange improves 40% higher than traditional type.

♦ Advantage:
● Safety and Reliability
● No Deterioration or Variation in Performance● Advantages at Inclined Berthing
● Most Cost Competitive System● Soft Reaction Force for Ship and Jetty Structure
● Lower Mooring Forces under Rough Weather Conditions
2 No Deterioration or Variation in Performance
Yokohama Pneumatic Rubber Fenders utilize the compressive elasticity of air, therefore
performance deterioration due to fatigue is absent.
In the case of solid rubber fenders or foam-filled fenders, based on data were taken
from comparison tests of Yokohama Fenders, there are variations in performance. Such
performance variations are associated to changes of rubber or foam hardness occurring
as a result of cyclic compression and temperature change.
The good performance of the Yokohama Pneumatic Rubber Fenders remains unchanged
even at temperatures under -50 degrees Centigrade (-58 degrees Fahrenheit).
Transportation We can take the deflation pallet transportation and the entire fender transportation without deflation according to the requirements of customers. We always put the customer's requirements first.
