Underwater Lifting Bags
Due to the characteristics of air tightness and high pressure, air bag is the first choice for salvage engineering.
The lifting bag has the advantages of light weight, strong air tightness, deep water pressure resistance and convenient transportation. So it is widely used in wreck salvage, stranded ships, floating bridges, caissons and other floating salvage projects.
There are two types of PVC lifting bags, Water Drop type & Cylindrical type.
The bags can be inserted between the bottom of the ship and the bottom of the sea to pry up the sunken ship, and can also be used to restore the buoyancy of the ship itself. Each airbags can lift more than 200 tons in the water.
Characteristics
► High strength PVC
► Enclosed type, free accessories
► Light weight, easy to operate
► Shorten project cycle
► Large tonnage buoyancy
► Affordable price
Applications
◆ Shipwrecks
◆ Marine salvage
