1. Use of salvage lifting airbags
Salvage lifting airbags, also known as a roller bag or a ship-launched rubber airbag, which is made of a heavy synthetic tire cord layer, and the inner and outer rubber layers are in the shape of a long cylindrical balloon. Marine airbags for ship launches and dry docks for barges can be used in shipyards in Brazil, Indonesia, especially for barge launches, shores, ship transport and ship landings.
2. Compare with other launch methods
The Rollers Bag is an innovative ship launch technology that compares to “terminal launch”, “side ship launch” and “floating”. The ship launch technology overcomes the limitations of side-fired fixed launch orbits. Thanks to the advantages of saving time, saving investment, flexibility and safety, ship launch airbags are accepted by more and more shipyards around the world. The largest ship has reached 100,000 DWT by launching airbags from ships.
3. Material and structure of salvage lifting airbags
The salvage lifting airbag is composed of an outer rubber layer, a multi-layer heavy synthetic tire ply and a firmly vulcanized inner rubber layer. The salvage lifting airbag is a cylindrical airbag body with two tapered heads and ports. The airtight rotary and air intake kit is tightened with the port. See the picture below.
1. End cap/plug of sealed end (Q235 H.D.G or stainless steel)
2. Rubber pads at both ends (enhanced sealing)
3. End protection clips at both ends (Q235 H.D.G or stainless steel)
4. Salvage lifting airbags
5. Safety is air inflated at one end and airtight at the other end (Q235 H.D.G or stainless steel)
6. Three direct connection of the inflatable end (Q235 H.D.G. or stainless steel)
7. 3/4' ball valve (brass)
8. Hose connection at the expansion end (Q235 H.D.G or stainless steel)
9. High quality pressure gauge on the inflated end.
4.Classification of salvage lifting airbags
Salvage lifting airbags are categorized by "ordinary airbags", "high-bearing capacity airbags", and "Super-high-bearing capacity airbags" according to the bearing capacity.
Ordinary airbags - the air bag with 3, 4 or 5 layers of cord fabric
High-bearing capacity airbags - the air bag with 6, 7 or 8 layers of cord fabric
Super-high-bearing capacity airbags - the air bag with 9, 10 or more layers of cord
