Buoyancy Bags 3 Ply PVC Diving Salvage Flotation Buoyancy Assit
Rescue
Description
Buoyancy Bags, often referred to as underwater lifting bags, are
specialized devices designed for lifting heavy objects in submerged
conditions. Made from durable, high-strength materials like PVC or
rubber, these bags can withstand significant pressure and harsh
underwater environments. They work by trapping air inside the bag,
creating buoyancy that allows for the safe and efficient lifting of
heavy loads, such as sunken vessels, machinery, and debris.
Buoyancy Bags are commonly used in salvage operations, underwater
construction, and marine transportation, offering a cost-effective
solution for lifting and repositioning submerged objects without
the need for cranes or other complex equipment.
