Yokohama fenders are the most famous pneumatic fenders. In most cases, Yokohama fenders are equivalent to pneumatic fenders. The size 500×1000 of Yokohama fenders refers to the type of fenders with the diameter of 500mm and the length of 1000mm. They are popular in the world for their excellent performance on protection the berthing vessels and dock structures.
The Yokohama fenders are manufactured with high-quality materials, mainly rubber material. The reinforced rubber material is strong and robust but elastomeric. The requirement of high deflection can be fulfilled by the rubber material. On the surface of the Yokohama fenders, many other protection methods can be used, like the chain and tire net. Different types of outer protection layer can be chosen in different application scenarios.
The Yokohama fenders usually will be connected with chains whose another ends are fixed onto the dock structures. This installation method can ensure the flexibility and can also keep the fenders in certain area. The fenders can be packed with air, which can save a lot of area in delivery.
