Industrial Using 2 Cord Heavy Object Rubber Lifting Airbags
Product Introduction:
Rubber lifting airbag is updated based on the ship launching airbags. This update makes heavy lifting airbags are more suitable for heavy lifting and moving work. Heavy lifting airbags have a different structure from the ship launching airbags. It can roll steadily when taking the load.
The rubber lifting airbag is one kind of the toughest inflatable lifting airbag. It can be used for heavy lifting and moving of huge heavy structures, caisson, buildings, etc.
Heavy lifting and transportation relying on heavy lifting airbags are cost-effective and flexible. Heavy lifting airbags will provide you with a unique capability of land transport very large vessels, heavy loads, or heavy construction .
The deflated heavy lifting airbag is very flat and can be placed under a grounded or stranded vessel that is hard aground. As little as 12 inches will provide very quick placement of lifting airbags under the hull.

Lifting Capacity
The bearing capacity of heavy lifting airbags were calculated based on the working pressure, contact area. Herein, working pressure was got upon the burst pressure and safety working factor.
Because of the flexibility of rubber airbag, the contact area will be effected by some terms. It inludes carried shipcondition, the different position from gravity center during the process of ship launching and landing. So the bvearing capacity of rubber airbags will vary as well as the contact area.
The approximate bearing capacity can be calculate as follows:
F=PS S=π x (D1-D2)/2
Where:
F is the bearing capacity
P is the working pressure
S is the contact area
P is the percentage of deformation (%);
D1 is the original diamater of the airbag (m);
D2 is the height of the compressed airbag (m)
Attention During Application
1. Working pressure must be controlled strictly, it is not allowed to exceed the working pressure.
2. No sharp and protruding hard object on the contacting surface of the airbags, to avoid the puncture on the skin of airbags.
3. Avoid the distortion along the length of airbag.
4. Empty inflating test must be performed if the airbags were not used for a long time or after reparation. The pressure should be as same as the testing pressure of our company. Inspectors must be at least 3 meters away from the airbags. For repaired airbag which was damaged in large scale, its working pressure should be lowered reasonably. Besides, annual check should be conducted on airbags which are used frequently.
5. Don’t drag the airbags on the ground.
Storage of The Airbags
1. If the airbags won’t be used for quite a long time, it shall be washed and dried, filled with talcum powder inside and coated with talcum powder outside, place it in dry, shady and ventilated place in the warehouse.
2. Place string the airbags should be far away from the heat source.
3. The temperature of the warehouse should be kept no more than 30℃.
4. Keep the airbags away from acid, alkali, grease and organic solvent.
5. The airbags should be stretched flat when not used. It is not allowed to pile up and stack heavy object on the airbag.
