Dia1.5m L12m High Bearing Capacity Pull Out The Boat Ship Launching Airbags
Product Introduction:
History of Ship Launching Airbags.
The airbags is invented in China in about 1986 by some experienced
engineers, to help launching small boats in rivers. After years of
development of technology, the airbags are adopted to launch huge
ship weigh up to 9000 tons or more.
Material: an airbag contains several layers of rubber-dipped Nylon
fabric+1 layer of rubber. For example,
7 layers of airbag, means 7 layers of rubber-dipped Nylon fabric +
1 layer of outer rubber.
Technical Requirement
According to CB/T 3795--1996, marine rubber fender should meet the following requirements.
1. Dimensional Deviation
Diameter & Effective Length Deviation: ±2%
Total Length Deviation: ±4%
2. Amount of Elastic Deformation: diameter deformation amount ≤ 5% under 1.2 times working pressure.
3. Safety Factor: >4.5
4. Air Tightness: depressurization < 5% after 1hour inflation
5. Surface Quality: fairing line shape, no crack, no bubble, no double skin, no impurities, no distinct dirt and other apparent defect.
6. end part anti-explosion design

Caculation of Performance of Airbags
As a soft flexible body, airbag’s shape depends on various factors,
such as the shape of ship bottom, ramp shape, width of ship bottom,
length of airbag, position of airbag under the ship, etc.
Users should calculate the bearing capacity of airbags basing on
above factors, correct bearing capacity accordingly.
Formula: Bearing capacity F=PS
P=pressure in the airbag(MPa)
S=contacting area between ship bottom and airbag(M²)
S= π*(D1-D2)/2
Storage of The Ship Launching Airbags
1)If the airbags won’t be used for quite a long time, it shall be
washed and dried, filled with talcum powder inside and coated with
talcum powder outside, place it in dry, shady and ventilated place
in the warehouse.
2)Place string the airbags should be far away from the heat source.
3)The temperature of the warehouse should be kept no more than 30℃.
4)Keep the airbags away from acid, alkali, grease and organic
solvent.
5)The airbags should be stretched flat when not used. It is not
allowed to pile up and stack heavy object on the airbag.
Application:
Ship Lifting, Launching And Docking
Heavy Structures Lifting And Transferring
Sunken Ship Floating And Salvage
Concrete Culvert Making
