Ship Launching Airbags are used wildly in many shipyards for ship launching and hauling out the heavy lifting, and ship salvage. Nanjing Deers airbags are designed with the outer layer, inner layer, and reinforcement layer, also with swivels and safety air inlet on the two ends. Airbags range in size from 0.8 to 2.5m diameters, with lengths of 6.0m to 23.0m ‘effective length’. A well-designed cylindrical structure makes it easy and convenient when working. Airbags are mainly used for ship launching and ship salvage.
Before many middle and small shipyards are enslaved to the traditional ship launching methods like sliding plate and slide rail. Airbags overcome this problem by its effective, safe, and economic characteristics. After years of development, our airbags factory can achieve the launching of a 50, 000 tones ship now.
Compared with the traditional launching method, the Marine airbag is of great environmental protection, because the Marine airbag can assist the ship launching at any seaside, so there is no need to worry about the construction of launching facilities.

Marine Airbags Application
Invented in China, airbag technology has become widely used for shipping launching, heavy lifting and moving, and buoyancy with superior advantages.
Marine Airbags Functions：
Air-lifting function
Drain function
Jack up function
| · For ship upgrading, conversion, or new/repair launching | · Marine airbag for salvaging sunken ship or heavy immersed steel structure |
| · For hoisting and transporting heavy goods up to 50,000 tonnes structure on land | · Inflatable mandrel for construction |
| · For tunnel culverts to stop leaks | · For heavy lifting |
Marine Airbags Production
The marine airbag can be widely used, the most important reason is that it is easy to operate, there are no special requirements for the use of Marine airbag environment, the site is very limited, and do not need the cooperation of other large equipment. In this way, the use of Marine airbag operation, can greatly shorten the construction period, reduce the construction cost, save a lot of money. The quality of airbags produced by Nanjing DEERS is high, and the specifications can be customized according to the requirements. The feedback from customers also proves that the Marine airbags produced by us have the characteristics of safety, efficiency, environmental protection, flexibility, and so on.
Ship Launching Airbag Safety Precaution
1.Overpressure Control
Strictly control the operating pressure, overpressure is forbidden.
2.The Landing Slipway Requirements
The landing ground should be ground or cement concrete, according to the tonnage of different ships.
3.Avoid Sharp Objects
Make sure no sharp objects and make sure the smooth and clean ground during using them in case of break of airbags.
Ship Launching Airbag Storage
1. When the airbags are not to be used for a long time, they should be drained, cleaned, dried, filled with talc power, and the exterior surfaces should be coated with talc power.
2. The airbags should be maintained in a dry ventilated room and be protected from light.
3. The airbags should be kept away from any heat source.
