Product Description

DOOWIN Ship Launching Using Airbags Heavy Duty Lifting Marine Rubber Airbag
Heavy lifting air bags, known as marine rubber airbags or ship launching balloons, are made of heavy-duty synthetic-tire-cord layers with inner and outer rubber layers in a long cylindrical balloon shape.
The heavy lifting airbag is updated based on the ship launching airbags, making them more suitable for heavy lifting and moving work. These airbags have a different structure from ship launching airbags and can roll steadily when taking the load, unlike inferior products which are prone to twisting.
As one of the toughest pneumatic lifting airbags available, they can be used for heavy lifting and moving of huge structures, caissons, buildings, and more. Each heavy lifting airbag can reach a lifting capacity of over 1,000 tons.

Classification of Heavy Lifting Airbags
Heavy lifting airbags are categorized by bearing capacity per meter in length, with layer count determining Safety Working Pressure. Custom types are available upon request.
  • QP - Ordinary airbag with 3, 4 or 5 layers of cord fabric
  • QG - High-bearing capacity with 6, 7, or 8 layers of cord fabric
  • QS - Superhigh-bearing capacity with 9, 10, or more layers of cord fabrics
Example: QG6/1.5*15
QG6: 6 layers cord fabric
1.5: diameter is 1.5m
15: length is 15m
