Navio que lança airbags

Airbag de borracha marítima é feito de uma mistura de borracha natural e corda de nylon, o ar comprimido é utilizado como material de enchimento, e o navio é descarregado e levantado por deformação de compressão de ar. 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.

Os nossos airbags de borracha marítimos utilizam uma nova tecnologia de produção de enrolamento 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.
• A fórmula de borracha profissional aumenta consideravelmente o tempo de serviço do airbag, que é duas vezes mais longo do que o do airbag normal.
• 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.

Principais caraterísticas dos airbags marítimos

• Flexível em vários projectos de lançamento: Airbags can be made to be specified sizes and layers as per the requirements of different launching projects.
•  Fácil de utilizar: 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.
• Durável e reciclado: Os airbags marítimos podem ser utilizados várias vezes de forma repetida.
• Economia elevada: Uma vez que os sacos de ar marítimos podem ser utilizados repetidamente e o seu custo não é elevado, o lançamento ou a atracagem de navios com sacos de ar marítimos pode poupar muitos custos aos estaleiros navais ou aos 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.
• Comprimento efetivo: 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.
• Diâmetro: 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.
• O número de camadas: 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.
