0.7-2m Diameter Boat Lift Airbags / Boat Air Bags Easy Installation

Product Description:

Marine Airbags have the best designed structure which consists of five different functional membranes in rubber layers.And they are made by patented whole enlacing technology which eliminates joints of cylindrical bodys with hemispherical heads.

Marine airbag also known as rubber airbag, ship air bags, ship launching airbag, ship salvage airbag, boat salvage airbags, inflatable airbag, ship lifting bag, air balloon, made by rubber & multi layer of rubber-dipped tyre fabric. Airbags are widely used in launching and landing ship/ boat/vessel, lifting and moving heavy goods, salvaging stranded boats. Marine airbags are very popular with shipyard, ship owner, and marine supplies company now.

Features:

• 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.

HOW TO SELECT SHIP LAUNCHING MARINE AIRBAGS ?

Length

Select the airbag's effective length not less than the maximum width of vessel.But when you arrange two rows of airbags keep in mind to calculate the total length of two rows to avoid contact of airbags.The total length of airbags can be estimated to be effective length plus diameter.

Diameter

Diameter of airbag is decided by the height of your vessel's support blocks.If the support block is 1m high,then you should choose airbag's diameter not less than 1.5 m.If you get 1.5 m high blocks, the airbag with 2m diameters will suits you well.

Plies

Marine airbag's performance is decided by its component plies.Generally speaking,airbags with 6 plies are enough for most engineering works. Only in some rigorous situation,airbags will need 7-8 plies to enhance its performance.
