Product Description:
Marine rubber airbags are also know as marine airbags and ship launching airbags. It's made by synthetic-tire-cord reinforcement layers and natural rubber layers.
Marine Rubber Airbag is China independent intellectual property rights of innovative products, the products are mainly applied to ship launching and landing, weight lifting, handling, installation of underwater buoyancy aid etc. Nowadays, marine rubber airbags are widely used in the world. The Products are less limited by space, no large mechanical equipment, can shorten the working period and save the unnecessary cost. Through years of development practice, marine rubber airbag is become more safety, effective and green environmental protection.
Comparing to the traditional slipway docking and launching method, the marine rubber airbags are much environmental, It's low cost and low risk. Unlike most other launching methods that are fixed infrastructures, ship docking airbag has relatively less limitations and can be used in versatile ways. It overcomes the disadvantage of fixed track docking in which capacity of shipbuilding and ship repairing is limited by the fixed infrastructures especially in small and medium-sized shipyards. Marine rubber airbag can dock a ship at any seaside. Besides, the marine rubber airbags need little maintenance and can be used repeatedly.
The marine rubber airbags provide support to the hull of the ship, its rolling motion take a vessel out of the water or launch into water. Thus it is obviously more safety than other options like sideways launching.

1.Standard size of marine airbags
Diameter(D):0.8~2.0m
Effective Length(EL):6~18m
Total Length(TL):7~19.5m
2 Standard number of layer
In order to confirm airbag's safety working pressure
we define the number of layers,which means the
number of synthetic-tire-cord layers.Normally we
offer marine airbags with 4,5,6,7,8 layers.Other
types are available upon request.
3.Material type of Synthetic-tire-cord
There are two kinds of synthetic-tire-cords with different performance.Refer to following table.
