Heavy Lifting Airbags

Dawson high-pressure heavy lifting airbags are the toughest large pneumatic lifting bags for the huge structure, concrete caissons lifting and moving.

Dawson’s High-pressure Heavy Lifting Airbags is updated based on the ship launching airbags. This update make heavy lifting airbags are more suitable for the heavy lifting work. The highest lifting capacity of each heavy lifting airbag can reach more than 1,000 ton.
 

Advantages of Heavy Lifting Airbags

Dawson heavy lifting airbags have the different structure with the ship launching airbags. Not the simple another application of ship launching airbags. It can roll steadily when take the load. The inferior lifting airbags are easy to twist.

You never find the below problems on our heavy lifting airbags.

Heavy Duty, High Pressure — our heavy lifting airbags use the special synthetic-tire-cord, which is stronger than the material used for the ship launching airbags. The highest working pressure can reach more than 400 kPa.

Super High Lifting Capacity — the maximum weight caissons move by heavy lifting airbags reach 5,000, cofferdams reaches 2,200ton.

Cost Effective, Flexible — the lifting and moving work using heavy lifting airbags doesn't need the slipway, trolley. Low reaction force on the objects, safe for structure.
 

Heavy Lifting Airbags Application

Heavy lifting and transportation relying on heavy lifting airbag is cost effective and flexible. Dawson heavy lifting air bags will provide you with a unique capability of land transport very large vessels, heavy loads, or heavy construction over ground where terrain would otherwise prevent such an operation.

The deflated marine 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 marine air bag under hull.

Performance of Heavy Lifting Airbags

Dawson have wide heavy lifting airbags in capacities from 70 ton to over 1,000 ton per bag, when compress deformation reaches 70% and inner pressure reaches the rated working pressure. Dawson has a selection of marine air bags with diameter 0.8m to 2.0m, and 6m to 20m in length to cover virtually all application.
