Inflatable rubber fenders (by the ball)
The rubber ball is one of the inflatable fender products, and it is one of the most advanced fender products in the world. It uses compressed air as a buffer medium to absorb the impact energy of the hull, which is similar to the general compressed rubber fender products. It has a special air impact function, so it is an ideal protective equipment for ships when berthing at sea and port terminals.
There are two types of inflatable rubber fenders
1. Mesh fender: The fender is covered with a protective net, which consists of chains, wires or optical fibers and is usually used with tires or rubber sleeves.
2. Sling fender: This fender has no protective net, light weight and easy to operate.
