The size 2500×4000 of Yokohama fenders represents the fenders with the diameter of 2500mm and the length of 4000mm. Yokohama fenders are also called pneumatic fenders. They need to be inflated with air or hydrogen when working, which can provide them with large compression capability.
Yokohama fenders can also be divided into several types with different protection layer, such as chain and tire net and so on. In different application scenarios, they have different functions. But all types of layers can reduce the damage to the fender body on berthing process or ship to ship operation. This can extend the lifespan of the fenders as well.
Yokohama fenders are manufactured with high-quality rubber materials, which allows them to carry out heavy duties. When they are off duty, the Yokohama fenders can be deflated to store. This are convenient for some customers with limited storage space, especially for ships. With only chains connected to the Yokohama fenders, the fenders have finished installation. It is time saving and can be prepared as the backup fenders in emergency.
