Product Introduction:
Heavy 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 heavy 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.

Tank lifting
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)
