Pillow Shape Underwater Lift Bags Inflatable Flat Rescue Air Lifting Bag
Description
Underwater lift bags are essential tools used in various marine and underwater applications to provide buoyancy and facilitate the lifting of submerged objects. Made from durable materials such as PVC and nylon, these bags are designed to withstand harsh underwater conditions and can lift weights ranging from a few kilograms to several tons, depending on their size and design. They work by being inflated with air, creating buoyancy that allows them to lift heavy items like salvage equipment, sunken vessels, and construction materials to the surface. Whether utilized in commercial diving, salvage operations, or underwater construction, lift bags are invaluable for safely retrieving items from depths and managing underwater tasks efficiently.
