2m x 12m Inflatable Rubber Air Bag for Lifting and Launching Barges
Marine rubber airbag typically has a body of cylindrical shape and
two conical heads, one at each end. At each head end, there is a
metal bushing as a mouth for air inflation and the plug with a
ring. Marine air bags 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 air bags
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 air bags.
Key Features of Lifting and Launching Ships Marine Air Bags:
1. Flexible in various launching projects: Launching ship air bags
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 air
bags 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
4. Less cost: As marine air bags 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.
The Size and Specifications of Rubber Marine Air Bags
According to different launching requirement, marine rubber air
bags can be made into various sizes and layers accoding to the ship
size and weight and the launching or docking conditions.

How to Launch Vessels with Marine Air Bags
Below is the general process of launching ship with marine rubber
I. Get enough suitable air bags ready
II. Level and Clean the launching slipway to make sure no nails or
III. Tie the ship to the winch with steel wire
IV. Lay airbags under ship bottom at suitable locations
V. Inflate the airbags to lift the ship away from the blocks and
remove the blocks
VI. Lower the lifting height properly by releaseing some air
VII. Slowly release the wire and roll the ship slowly backward to

Material and Construction of Luhang Marine Launching Air Bags
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.
