Lanzamiento de airbags

Airbag de caucho marino está hecho de caucho natural mezclado y cuerda de nylon, el aire comprimido se utiliza como material de relleno, y el barco es descargado y levantado por la deformación de compresión de aire. The use of airbags can save the cost of a shipyard, a building dock, and a launching slipway, has the advantages of convenience, safety, and repeated use, and can effectively deal with the launching in bad terrain.

Nuestros airbags marinos de caucho utilizan una nueva tecnología de producción de bobinado integral

• The new technology that the head is two layers more than the body strengthens the intensity of the airbag’s use, and its airtightness and safety are also significantly improved.
• La fórmula profesional del caucho prolonga enormemente el tiempo de servicio del airbag, que es el doble que el del airbag ordinario.
• Standard nylon cord fabric, with 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 seashores in Asian and American countries. Marine airbags are often called ship launching airbags, which indicates 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 with a DWT below 60,000 are launched by marine airbags.

Características principales de los airbags marinos

• Flexible en diversos proyectos de lanzamiento: Airbags can be made to be specified sizes and layers as per the requirements of different launching projects.
•  Fácil manejo: 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 into the water. It does not impose a strict requirement on slipway conditions. Ship launching can be executed even in tough conditions.
• Duradero y reciclado: Los airbags marinos pueden utilizarse muchas veces de forma repetida.
• Alta economía: Como los airbags marinos pueden utilizarse repetidamente y su coste no es elevado, botar o atracar buques con airbags marinos puede ahorrar muchos costes a los astilleros o armadores.

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.
• Longitud efectiva: The effective length should be the same as the ship’s breadth, or 1 meter shorter than the breadth. We can make airbags in lengths from 5m to 24m.
• Diámetro: Select a 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 the bottom, choose bigger airbags so that workers can work in a more comfortable posture under the ship. Diameters of 1.5m, 1.8m, 2m, or 2.5m are all suitable and available for large ships.
• El número de capas: The more layers the airbag has, the bigger its 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, then airbags will need higher pressure and more plies to ensure safety.
