Enviroguard provides underwater lifting bags specifically designed for load handling and marine salvage operations within the diving industry. Heavy Duty Air Inflatable Lift Bags come in various styles, including Enclosed Style, Open Bottom Style, Tetrahedron Style, and Pontoon Style. Air lifting bags are all turnkey ready and collapsible for easy storage and economical transport.
Lifting Bags are diving equipment consisting of a robust and air-tight bag with straps that is used to lift heavy objects underwater by means of the bag’s buoyancy.
The heavy objects can be moved horizontally underwater by a diver or sent to the surface without help. It is crucial to choose a lift bag that has the appropriate capacity for the task. If the bag is grossly oversized a runaway or otherwise out of control ascent may result.
Underwater lift bags may also incorporate dump valves to allow the operator to control the bags' buoyancy during ascent. If a single bag is insufficient, multiple bags may be used and should be distributed to suit the load.
Lift bags can also be used to support loads on the water's surface. These air lifting bags come with a single positive venting relief or dump valve located in the center of the top lift plate. This valve is spring-loaded, allowing it to automatically open when it detects excessive pressure.
Enviroguard marine salvage bags feature a totally enclosed cylindrical design, commonly known as enclosed air lift bags, inflatable buoyancy units, or salvage pontoons.
