Marine Lift Bags Manufacturer , Airbag Launch For Vessles
Marine Airbag for ship launching have the best designed structure
which consists of three different functional membranes in rubber layers.
1) Outer Rubber Layer
The outer rubber layer that covers the outside of marine airbag to
protect under layers from abrasion and other external forces. This
compound has sufficient tensile and tearing strength to withstand
any condition and hard usage.
2) Inner Rubber Layer
The inner rubber layer seals pressurized air inside marine airbags.
3) Synthetic-Tire-Cord Layer as Reinforcement
The reinforcement cord layers, which are made of
synthetic-tire-cord commonly used in tires, are arranged at ideal
angles to hold the internal pressure and distribute stress evenly.
So they can provide strong efficient reinforcement.
1. usually produce and supply airbags in size of following as per
customer’s launching requirement:
Diameter: 0.8m, 1.0m, 1.2m, 1.5m, 1.8m, 2.0m, 2.5m
Effective length: 5m-24m
Layer: 4-10 layers
| Dia | Effective Length | Layers with cord | Working Pressure | Bearing Capacity |
| Lifting Height | Tons/Airbag |
| 1.2m | 10m | 6 | 0.17mPa | 0.9m | 78.51 tons |
| 1.5m | 12m | 8 | 0.18mPa | 1.2m | 100.50 tons |
| 1.8m | 15m | 8 | 0.15mPa | 1.5m | 104.69 tons |
| 2.0m | 18m | 10 | 0.17mPa | 1.5m | 235.54 tons |
| 2.5m | 18m | 12 | 0.16mPa | 2.0m | 226.12 tons |
The Security issues of airbag usage
1.Super pressure control
To strictly control the working pressure, shall not exceed the
stipulated in table 2 of the pressure of work
2. Spikes to avoid
The surface contact with airbag is not sharp outstanding
person,prevent punctured.
3.Prevent distortion
The airbag in scrolling process avoid length direction generate
distortion, Such as when the Catamarans ashore and down , if use
done airbag easy to generate distortion. So please put two airbag
in Catamarans below.
4.Exempt impact
Balloon inflated should avoid impact load. Especially in the ship
fall pier, When the airbag as lifting has lifted most hull, To
remove piers of wood and fill in scrolling the airbag process,if
left one, two piers were still tightly, Don't touch it. Because the
pier wood cut down, once the impact of hull gravity might make
airbag burst. Should adjust the airbag pressure, Make leaving ship
from piers of wood. And as with nothing in the process of moving
ship collision, When will cause serious damage airbag.
5. Pressure test
Not long after the repair or airbag before revived, shall be
carried out before reactivated no load charging test. Test pressure
should take the pressure of work. Lab, inspector shall at least 3
meters away from the airbag. If after the repair damaged area,
should reduce airbag pressure of work. Every year, all common
airbag to the experiment,can ensure a safe use.
