Ship landing rubber airbags, also called marine airbags, docking airbags, ship lauching balloons, marie air bags , now have become one convenient ship launching method in the some shipyards, especially where slipways are not available.

Qingdao Florescence is the first company that initiated airbags for ship launching in China from year of 1992. During the 20 years' development and experience in airbag production and ship launching, our ship launching airbags have become the most reliable.

1. Airbag body
The airbag body is composed by natural rubber and strength fiber material through vulcanization progressing

2. Terminal iron part
The terminal iron part is made of cast iron, it is combined closely with the airbag body, one end is for pulling when you move it, and the other end if for charging and discharging the air.

An rubber roller airbag is to be constructed of an outer rubber layer, one or more synthetic-tyre-cord layers, and an inner rubber layer. The arrangement of synthetic-tyre-cord reinforcement layers is shown in the picture below, all materials shall be vulcanized firmly.

We usually produce and supply airbags in size of following as per customer's launching requirement:
Diameter: 0.8m-2.8m
Effective length: 5m-24m
Layer: 3-10 layers

1. Ship Launching and Landing
2. On Land Construction
3. Ship Salvage
4. Objects Lifting
5. Caission Floating
6. Marine Engineering

1.High pressure
Special synthetic-tire-cord reinforcement make airbags stronger with working pressure up to 400 KPa.

2.High lifting capacity
One piece bag can lift heavy structures ranging form 70 tons to 1,000 tons in weight. Normally, caissons up to 5,000 tons or cofferdams up to 2,000 tons can be lift by our heavy lifting system.

3.Steady roll movements
When airbags are taking the load, they can roll steadily with large contact area and less reaction force to secure a smooth transportation and relocation.

4.Easy to operation
Only compacted ground and minimum facilities such as trolleys are needed. Meanwhile, heavy lifting airbags are easy to install as the deflated airbags are very fat and small to be placed under vessel's hull.

5.Lower cost 
Using airbags helps to decrease 70% budget comparing with traditional lifting methods.

1.Less land form limited
Only need enough bearing power ground and no sharp objects 

2.Minimum fixture needed
Need no more than air compressors,winches and steel ropes

3.Environment Protective
Do no harm to the environment. No chemical needed.

4.Time & money saving
Marine airbags are much cheaper and portabler than other methods.
