Pneumatic Fenders (Yokohama Fenders) use air as the medium and use compressed air to absorb impact energy, making the ship more flexible and softer when it is docked, so as to achieve the effect of anti-collision and anti-collision. Compared with the traditional elastic rubber fender, it has the characteristics of large impact energy absorption, small anti-impact force on ships, simple installation, good elasticity, no deformation under compression, light weight, practical and economical, etc. In recent years, with the continuous development and growth of the shipbuilding industry, this kind of fender has been widely used in large oil tankers, ocean shipping ships, offshore facilities, offshore platforms, port terminals, large docks, yachts and other fields.
The pneumatic fender is a rubber airtight container made of rubber cord fabric as the skeleton material. After the ball is filled with compressed air, it can float on the water surface. It is used as an important buffer medium for berthing between ships and berthing between ships and bows. At the same time, the inflatable rubber ball can absorb the impact energy of the ship’s movement, reduce the ship’s recoil force, have a softer impact on the wall, and the area pressure acting on the ship is low, which greatly improves the safety of the ship’s berthing.
The sphere of the inflatable rubber fender is composed of inner rubber, outer rubber and reinforcement cord. All layers are vulcanized and formed together, and finally hydrostatically tested. The rubber compound of the outer layer is designed and manufactured to withstand severe use, including in harsh operating environments; while also protecting the carcass ply and inner rubber layer. Through the design of the ball layout, the scraped nylon dipped cord can evenly distribute the load force of the ball, and the inner rubber layer is completely sealed.
