    High Buoyancy Floating Marine Lifting Rubber Airbag Dia 2.0m Length 10m

    Vulcanize Rubber AirBag Dia and Length Customize Ship Lifting Marine Air bag

    “Ship Launching marine airbag is a kind of inflatable air bags with high pressure used for launching a vessel. It is also named marine airbags, ship launching balloon, roller bags, air lifting bags, invented in 1980, which is a modern launching methods in the shipbuilding industry nowdays.


    Luhang is professional manufacture of ship launching / landing salvage rubber air bag and ship berthing fender.


    Performance Calculation Principle of Airbags


    The bearing capacity of ship launching rubber air bags was calculated based on the working pressure, contact area. Herein, working pressure was got upon the burst pressure and safety working factor.Because of the flexibility of rubebr air bag the contact area will be affected by some terms which include the carried ship condition, the different position from gravity center during the process of ship launching and pulling. So the bearing capacity of rubber airbags will vary as well as the contact area.


    The approximate bearing capacity can be calculated as follows:

    F=PS
    S=π x (D1-D2)/2

    Mark:
    F: Bearing capacity

    P: Inner pressure

    S: Contact area

    D1: Diameter of airbags when free of loat

    D2: Working height of airbags when loaded

    Preparation
    1. According to the calculation, prepare enough airbags, towing winches, air compressor and other insturments needed.
    Before Operation, airbags should be inflated with 1.25 times pressure of working pressure to test its safety and airtightness. If there is any problem, airbags should be fixed before use.
    2. Clear all the obstacles and sharp iron nail from launch ramp. Check vessel bottom to ensure no welding scar which may puncture airbags.
    3. Fasten towing winch with ship
    4.Close all vessel's valves, fix the helm and screw propeller.


    5.Insert airbags between support blocks and inflate them to lift vessel. When vessel is lifted, people can take out support blocks under the ship.
