Pneumatic Dock and Ship Berthing Bumpers 3m x 6m

Pneumatic Rubber Dock and Ship Berthing Bumper is a leading anti-collision device for marine application in the world today. Yokohama Pneumatic Bumper has become an idea ship protection medium used extensively by large tankers, LPG vessels, ocean platforms, large docks, harbor and wharfs.  Through hard work of 2 decades, Qingdao Luhang has grown to be the only one manufacturer in China that can produce Yokohama Pneumatic rubber fenders of 4.5m x 9m thanks to the largest vulcanizaiton tank. Large size yokohama marine fenders are ideal for permanent and semi-permanent port and ship-to-ship transfers requiring minimal maintenance for large vessels such as bulk carrier, LNG  Vessels. Yokohama pneumatic rubber fenders are made of synthetic-cord-reinforced rubber sheets with compressed air inside at initial pressure of 50kPa (low pressure) or 80kPa (high pressure) to enable it to float on water and work as a shock absorber between two ships or between ship and a dock. Although manufactured using different techniques, both low and high pressure fenders work by the same principle.
