1.8M x 15M Lifting and Launching Barge Marine Rubber Airbag in Shipyards
Rubber marine airbags are widely used for lifting and launching ships and boats in shipyards, specially for medium and small shipyards alongside rivers and seasides in Asian and American countries. Marine air bags are often called ship launching airbags that indicate the most popular application of these heavy duty air bags is for ship launching. It is estimated that more than 80 percent new built ships who’s DWT below 60,000 are launched by marine airbags.
Key Features of Launching Vessel Marine Airbags:
1. Flexible in various launching projects: Launching ship airbags can be made to be specified sizes and layers as per the requirement of different launching projects.
2. Easy Operation: The operation of launching vessels with rubber air bags is releatively easy, just laying out and inflating the airbags to lift the vessels and roll them to the water.
It has not strict requirement on slipway conditions. Ship launching can be executed even in tough conditions.
3. Durable and recycled: Marine Airbags can be used many times repeated.
4. Less cost: As marine airbags can be used repeatedly and its cost is not high, launching or docking ships with marine airbags can save much cost for shipyards or ship owners.

How to Launch Vessels with Marine Airbags
Below is the general process of launching ship with marine rubber airbags.
1. Get enough suitable air bags ready
2. Level and Clean the launching slipway to make sure no nails or sharp stones
3. Tie the ship to the winch with steel wire
4. Lay airbags under ship bottom at suitable locations
5. Inflate the airbags to lift the ship away from the blocks and remove the blocks
6. Lower the lifting height properly by releaseing some air
7. Slowly release the wire and roll the ship slowly backward to the water

Material and Construction of Luhang Marine Launching Airbags
The marine air bag wall is constructed with layers of rubbers plates. The inner layers are reinforced with nylon cord net. These layers support the airbag with bearing strength when the airbag is inflated. More layers the airbag wall has, greater strength the airbag has. And the nylon cord net plays a critical role in strength. Besides the cord reinforced layers, there is one extra layer without cord net outside the wall. This rubber layer has a function of anti-wear and anti-aging. To maximize the function of the inner layers and the exterior layer, the rubber material is specially optimized with suitable mixing formulas.
