Natural Rubber Marine Launching Airbags With Different Size
Usage of Marine Airbags
Ship Launching Marine Airbags, also known as roller bags or ship launching rubber balloon, are made of heavy-duty synthetic-tire-cord layers with inner and out rubber layers in long cylindrical balloon shape.
Comparison with other Launch Way
Rollers Bag is a innovative ship launching technology, comparing with "end-on launching", "side ship launching", "float-out". This ship launching technology overcomes the restrictions of fixed launching track of side-launch. Ship launching airbags are accepted by more and more shipyards world wide due to its advantages of saving time, saving investment, flexible, safety. The biggest vessel launched by ship launching airbags up to 100,000 DWT.
Features of Our Natural Rubber Launching and Landing Airbags
1. Outer and Inner Rubber Layers
Our marine rubber airbags are equipped with distinct outer and inner rubber layers. The outer rubber layer serves as a crucial protective shield for the underlying layers. It safeguards them from abrasion, which can occur during contact with rough surfaces such as the ground during launching or landing, or when rubbing against other objects in the marine environment. Moreover, it can withstand various external forces. This rubber compound is engineered to possess sufficient tensile and tearing strength. This strength enables it to endure any challenging conditions and heavy usage scenarios that the airbags may encounter during their operation in the marine industry.
2. Synthetic - Tire - Cord Reinforcement Layer
The reinforcement of our airbags is achieved through synthetic - tire - cord layers. These layers, made from the same synthetic - tire - cord commonly employed in tires, are arranged at optimal angles. This strategic arrangement is designed to effectively hold the internal pressure within the airbag. When the airbag is inflated, the pressure exerted from the inside needs to be contained. The synthetic - tire - cord layers ensure this containment. Additionally, they play a vital role in evenly distributing stress across the airbag structure. By doing so, they provide strong and efficient reinforcement, enhancing the overall durability and performance of the airbag. This reinforcement mechanism allows the airbag to maintain its shape and integrity even under high - pressure conditions.
3. End Fittings
Our airbags come with specialized end fittings. These include air - tightness swivels and safety air inlets. It's important to note that these end fittings are enclosed when the airbags leave our factory. The air - tightness swivel ensures that the air inside the airbag is properly sealed, preventing any leakage. This is essential for maintaining the required pressure within the airbag during its operation. The safety air inlet, on the other hand, is designed to allow for safe inflation of the airbag. It provides a controlled passage for air to enter the airbag, ensuring that the inflation process is carried out without any risks.
4.High - Pressure Launching Airbags
Our high - pressure launching airbags are available in a diverse range of sizes. The diameter of these airbags ranges from 0.8 to 2.5 meters, while the effective length varies from 5.0 to 24.0 meters. These airbags find extensive applications in the marine industry. They are primarily used for ship launching, haulouts, loading, and floating operations. In the case of cargo boats, they are instrumental in both the launching and landing processes. They can also be used for lifting and moving sunken ships, as well as salvaging stranded boats.

Classification & Size of HEAVY LIFT MARINE AIRBAGS
1. Standard size of Lifting Airbags
Diameter(D): 0.8~2.0M
Effective Length(EL): 6~18M
Total Length(TL): 7~19.5M
2. Standard number of layer
In order to confirm lifting airbags safety working pressure we define the number of layers, which means the number of synthetic-tire-cord layers. Normally we offer lifting airbags with 4, 5, 6, 7, 8 layers. Other type are available upon request.
