Diameter 500 to 3700mm Boat Bumper Rubber Yokohama Fenders
Product Introduction
Rubber Yokohama Fender is a marine anti-collision product made of compressed air. Compressed air is mainly used as the buffer medium to absorb the impact energy of the ship, making the ship more flexible and soft when docking, so as to achieve the effect of collision and collision avoidance.
Usually aircraft tires or truck tires are used toprotect the fender body. Both ends are equipped with shoulder straps, which are widely used for ship-to-ship transfer operations and ship berthing operations. Wait. The rubber Yokohama fenders are produced in strict accordance with ISO17357-2014 international quality standards, and the products are exported to all over the world.
Advantage of Shunhang Rubber Yokohama Fender
