Airbag per il lancio di navi

Marine rubber airbag is made of natural mixed rubber and nylon cord, compressed air is used as filling material, and the ship is discharged and lifted by air compression deformation. The use of airbags can save the cost of shipyard building dock and launching slipway, has the advantages of convenience, safety, and repeated use, and can effectively deal with the launching in bad terrain.

Our Marine rubber airbags use new integral winding production technology

• The new technology that the head is two layers more than the body strengthens the use intensity of the airbag, and its airtightness and safety are also significantly improved.
• The professional rubber formula greatly extends the service time of the airbag, which is twice as long as that of the ordinary airbag.
• Standard nylon cord fabric, high-pressure explosion-proof performance is safe and reliable.

Marine rubber airbags are widely used for ship launching and docking in shipyards, especially medium and small shipyards alongside rivers and seasides in Asian and American countries. Marine airbags are often called ship launching airbags that indicate the most popular application of these heavy-duty airbags is for ship launching. It is estimated that more than 80 percent of newly built ships whose DWT below 60,000 are launched by marine airbags.

Key Features of Marine Airbags

• Flexible in various launching projects: Airbags can be made to be specified sizes and layers as per the requirement of different launching projects.
•  Easy Operation: The operation of launching vessels with rubber airbags is relatively easy, just laying out and inflating the airbags to lift the vessels and roll them to the water. It has not a strict requirement on slipway conditions. Ship launching can be executed even in tough conditions.
• Durable and recycled: Marine Airbags can be used many times repeatedly.
• High economy: As marine airbags can be used repeatedly and their cost is not high,  launching or docking ships with marine airbags can save much cost for shipyards or ship owners.

How to Select Marine Airbags for Launching ships

• Ship launching airbags can be made into various sizes and layers according to the ship size and weight and the launching or docking conditions.
• Effective length: The effective length should be the same as the ship breadth, or 1 meter shorter than the breath. We can make airbags in length from 5m to 24m.
• Diameter: Select diameter based on the ship size and work requirement. Select bigger airbags for large ships, but smaller airbags for small boats. In case the ships need cleaning or repairing bottom, choose bigger airbags so that workers can work in a more comfortable posture under the ship. Diameter of 1.5m, 1.8m, 2m, or 2.5m are all suitable and available for large ships.
• The number of layers: The more layers the airbag has, the bigger bearing capacity it has. To lift a ship to a certain height, enough airbags with enough layers are needed. Generally speaking, airbags with 6 layers are enough for most engineering works. Only in some rigorous situations, airbags will need 7-8 layers to enhance their performance. For example, if people use airbags to lift heavy caissons but their contact area is limited, and then airbags will need higher pressure and more plies to ensure safety.
