Product Introduction:
Marine airbags can also be used for marine salvage airbags. Marine salvage and refloatation is another application of marine airbags after update.It's designed with lifting belts and shackles equipped on the update marine salvage airbags.
It can be used as salvage pontoon for the supporting docks, and other floating structures. Also can be used to salvage the shipwreck, rescue the floating bridge and dock construction. It really come into own when marine salvage airbags employed in heavy duty salvage work under severe environment.
Through inflating the compressed air to produce buoyancy, then using buoyancy to salvage. It is easy to operate and safe and reliable. In addition to hang a ship in a fixed position or connected with lifting jack of the bottom of ship, ship salvage airbag also can be placed inside the ship cabin, through filling out the cabin water to provide buoyancy.

Advantages comparing with PVC Air Lift Bags
PVC air lift bags are widely used for the diving or marine salvage industry. Marine salvage airbags are made by multilayer heavy-duty synthetic-tire-cord layers. It’s more sturdy and reliability than PVC air lifting bags, which is made only by one layer PVC coating fabric.
Super-high tensile strength — Heavy-duty synthetic-tire-cord layers is framework material of our marine salvage airbags. The breaking strength of each synthetic-tire-cord layer is more than 15,000 N / 5cm, which is two times of PVC coating fabric material.
Resistant to abrasion — The thickness of Evergreen Maritime marine salvage airbags is up to 12mm or more. The PVC air lift bag only is about 1.5mm. In bad environment, the PVC air lift bag is easily scratched or damaged by sharp objects. But our marine salvage airbags can resistant the scratch. Even the out rubber was damaged, the inner synthetic-tire-cord layer also can work well.
Multiple application — Normally, the parachute type PVC lifting bags used for the lifting work from underwater. The enclosed type lifting bags used for the buoyancy support of surface. But our marine salvage airbags are qualified for these two work, because of its high working pressure.
