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.

Why Choose Marine Heavy Lifting Air Bags

Superior manufacturing and quality control processes from raw material selection through the highly skilled production process ensure reliable performance.

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
