Product Description

In order to meet the requirements of the ship salvage and rescue industry, we have redesigned the launching airbag. These can now be used as pontoons to support docks and other floating structures, and are also very useful for laying pipelines and other underwater construction projects to provide buoyancy. However, the main application of "Marine Rescue Airbag" is in shipwreck rescue, floating bridge and dock construction, rescue and removal of sunken ships and tidal flat ships.

 

After being deflated, the sea salvage airbag is very small in size and light in weight. Therefore, they can be easily transported and deployed. They can be used vertically to get sunken ships out of deep water. When the boat is suspended near the water surface, it can be suspended below the boat, and one end on each side raises the boat to a high enough water level to pump it out. In shallow water, two bags can be thrown together like a floating boat, one on each side of the boat. They can also be used as road rollers to push stranded ships back into the water, just like our "ship launches airbag".

 

Advantage

 

1. Special synthetic tire cord layer material

Our "rescue tire" is made of a special synthetic tire cord layer, and its performance is much better than PVC coated fabric.

 

2. High pressure design

The maximum working pressure of the fishing pipe is 0.25Mpa. This means that they can be used at a depth of 25m.

 

3. Integral screw type wrapped rescue airbag

Our "ship rescue airbag" is a completely enclosed tube with a tapered end. It is manufactured using integral screw technology. This design ensures that there are no welds. This makes it stronger than RF welded salvage airbags.

 

4. With accessories

Our rescue kit is equipped with nylon straps and shackles with a safety factor of 6:1

 

Heavy goods handling:

Marine airbags are widely used in caisson lifting, transportation, launching and other fields in port construction, as well as component displacement and launching.

 

Floating and salvage:

Marine airbags can generate greater buoyancy and strong load-bearing capacity, and are now widely used in rescue of stranded ships and other buoyancy and salvage fields.

 

 

 

 

Airbag packaging and transportation:

According to the provisions of the CB/T 3795-1996 of the People's Republic of China Ship Industry Standard, the packaging, transportation and storage of marine airbags should comply with the following standards:

1. Packaging
Folded and packed with plastic woven bags.

2. Transportation
Airbags should be lifted, lifted, and rolled in an inflated state when transported on short distances. It is strictly forbidden to drag on the ground.

The airbag should be folded and fixed to the tray during long-distance transportation, with a cushion underneath, and wrapped with a wrapping film on the outside.

The development history of marine airbag:

According to related records, humans have been using the rolling wood principle to carry heavy objects more than 6,000 years ago. People still use the rolling wood principle to carry heavy objects in daily production and life. Marine airbag is a flexible heavy vehicle designed according to the principle of rolling wood.

In the 1980s, due to the manufacturing process and materials of airbags, the weight of airbag launching ships was between 100 tons and 500 tons.

In the early 1990s, people made innovations in the process and materials of airbag manufacturing: nylon cords replaced canvas as a new skeleton material, and a new type of integral winding manufacturing process was developed.

Some marine airbag manufacturers still use the old production technology of lap type. It is generally believed that the integrally produced marine airbag is more reasonable in structure and has a greater safety factor and bearing capacity.

Water-filled blasting test is an important method to check the performance of marine airbags.
