An inflatable lift bag is usually inflated with air once attached to any item needing to return to the surface.
What Is It?
These bags act as a buoyancy compensator that can be used to help raise sunken objects. It is usually made of polyester fabric and it is inflated with air.
How Are They Used?
These devices are designed for many uses in the marine industry. They are used to lift and transport heavy objects typically in construction and engineering projects.
They are also used to help divers stay underwater longer, and to help them ascend or descend their payload.
When a diver wants to ascend, they release some of the air from the bag and when they want to descend, they add more air into it.
What Are Their Advantages?
The advantages of using inflatable lift bags are:
- lightweight and portable
- require no external power source
- can be reused over and over again
- can be easily deflated for storage or transportation
Conclusion
Inflatable lift bags are a type of buoyancy device that is used for many different purposes. They can be used to increase buoyancy, as a floatation device, and as a rescue device.
