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.
