Marine Salvage Flotation Air Lifting Buoyancy Bag for Heavy
Equipment Lift
Description
Buoyancy bags play a crucial role in ship launching and recovery,
offering a safe and efficient method for lifting and moving
vessels. When placed under a ship, the bags provide the buoyant
force necessary to lift it from dry land or raise it from the
water. Constructed from high-quality materials, these bags are
designed to endure underwater pressures, harsh weather, and marine
conditions. Their flexibility in size and lifting capacity allows
them to be used in various ship types and sizes, making them ideal
for shipbuilders, marine engineers, and companies involved in ship
launching or recovery projects.
