Diameter 1.5m Marine Floating And Lifting Rubber Airbag Rollers
What are the advantages to using this launching system over traditional ship launching techniques?
An marine airbag ship launching system does not need the traditional fabricated slipway so it saves time, investment, land, etc. Marine airbags need no extra maintenance and after use they can be cleaned and folded in the corner to wait for another mission. It is easy to find that airbags’ elasticity can give more protection to the launched ship. A remarkable character of airbags is that the working height can be changed to redirect the ship or object being launched by adjusting the inner air pressure. For this character it is peerless compared to traditional ship launching techniques.
Features
●Airbags of different sizes are in stock
●Provide repair kit and on site instruction
●Long time service life can be reused many times
●Wear resistance and anti aging
●Good raw material and cord fabric
●Do no harm to the environment. Time & money saving
●Need no more than air compressors, winches and ropes
●Marine airbags are much cheaper and portable than other methods
Advantages of ship launching air bags
1.Less land form limited
Only need enough bearing power ground and no sharp objects
2.Minimum fixture needed
Need no more than air compressors,winches and steel ropes
3.Environment Protective
Do no harm to the environment. No chemical needed.
4.Time & money saving
Marine airbags are more cheap and portable than other methods.

Loading of airbags
The requirements of launching ship and relevant equipments.
1.Ship
The engineering work under water line shall wholly be finished,
especially those equipments, valves and others that are to be
installed at the openings under ship waterline,the installations
should be approved by inspection. All the burrs, welding beading
and the like on the ship bottom or appendages should be ground
away. All the welds on the shell plate must pass inspection and
tightness test. The main dimensions of the ship should be measured
up and the mark of loadline must pass inspection. All the paint
work of the shell plate has been finished.
2. Ramp way
The ramp way on which the airbags will rolling should be cleaned
and be clear of sharp fends such as iron nail. The ramp way should
be leveled and the level error from left to right should less than
80mm. The ground caved in should be filled up and the ground
bearing capacity should be relatively equalized. The ramp made of
mud land, sanded land, sands or concrete, however, its bearing
capacity should be twice as big as the working pressure of airbags.
The slope of ramp is to be determined according to the size of the
launching ship and is generally no bigger that 1/7. In the range of
the whole length of the ramp way, the shape may be of multiple
combination with slope line, are line and others. However, the ship
bottom should not contact the ground even when the airbags are at
their lowest working height. The ramp way should extend into water
for certain length.
3.Winch
In general, a slow winch is to be selected, its veering speed is
about 9-13/m/min. The moving speed of a ship must not be more than
6m/min with the control of hauling force of winch wire. If the ship
weight is less than 200t, the moving speed can be increased
properly. The wire must be inspected and replaced regularity.
4.Air compressor
The type and capacity of the air compressor is to be selected
according to the total volume of all the airbags provided for the
launching and time required for air filling and the air pressure.
The gas tank of air compressor should be installed with
adjustable pressure limiting valve.
Application
1.For ship upgrading, conversion or new/repair launching
2.Marine airbag for salvaging sunken ship or heavy immersed steel
structure
3.For hoisting and transporting heavy goods up to 10,000 tonnes
structure on land
4.For floating use purpose as improve the draft.
5. Container for storing and transporting gas and corrosive
chemical liquid and pure water for voyage
6.Rubber airbags used for culvert making
