salvaging airbag

Product Description

The structure of WINTON marine airbag: The structure of WINTON rubber airbag is shown in the picture. It consists of a bag body and an iron-end component. The bag body is manufactured by vulcanizing the preliminary shaped airbag made of base rubber and reinforced fiber material. The material of the iron- end component is metal, and it is connected to the bag body firmly.
Application:
1.Hoisting and moving airbags: They can be widely used for moving various large prefabricated reinforced-concrete products (such as caisson, box culvert, and bridge), oil drilling equipment and integrated building, etc.?
2.Floating and filling airbags: The corresponding buoyancy can be offered on the clients’ request for wreck salvage and underwater installation operation. Filling and floating gasbags can be flexibly used in the projects of wreck salvage, pontoon bridge installation, dock building, underwater transmission pipeline installation, etc. in many ways.
3.Ship landing and launching airbag: It is widely used for landing and launching the large-size, medium-size and small size ships, with the advantages of labor-saving, time-saving and capital-saving.
4.Mandrel airbag: It can substitute the wooden or steel mandrel used for pouring the hollow of large reinforced concrete structure.
5.Container airbag: It can be used as the gas or liquid storage and transport container.
6.Specifications Air-bags for Marine Use
Ship launching marine airbags are also known as inflatable bags, roller bags, air lift bags, and salvage bags. Standard air bag maximum diameter size range is 2.0m.

High-pressure ship launching marine airbags are used for ship launching, ship landing, ship lifting, loading, and floating. They are widely used in cargo boat launching and landing, lifting and moving sunken ships, and salvaging stranded boats. Marine airbags have the benefit of not only saving labor and time, but investment costs. Additionally they are flexible and dependable.

The technology of applying pneumatic roller-bags to the launching and landing of ships relieves the restrictions of traditional slide-board technology which is commonly used in building small or medium size ships. Years of trial and error with this technology has increased the ability of launching ***-ton ships to 7,***-ton ships!

*-layer marine airbags that are 1.5m dia x *5m long contain a rubber content that is not less than *1%. The air-bags can safely hold ***-tons with a safe working pressure of 0.*8MPa while rolling. When standing still the highest lifting pressure is 0.*0MPa while holding ***-tons.
*-layer marine airbags that are 1.5m dia x *5m long contain a rubber content that is not less than *1%. The air-bags can safely hold ***-tons with a safe working pressure of 0.*2MPa while rolling. When standing still the highest lifting pressure is 0.*4MPa while holding ***-tons.
