Lancement de coussins gonflables de sécurité

Coussin gonflable en caoutchouc pour la marine est composé de caoutchouc naturel mélangé et de corde de nylon, l'air comprimé est utilisé comme matériau de remplissage, et le navire est déchargé et soulevé par la déformation de la compression de l'air. 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.

Nos airbags en caoutchouc marin utilisent une nouvelle technologie de production par enroulement intégral.

• 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 formule professionnelle du caoutchouc prolonge considérablement la durée de vie de l'airbag, qui est deux fois plus longue que celle d'un airbag ordinaire.
• 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.

Principales caractéristiques des airbags marins

• Souplesse dans les différents projets de lancement : Airbags can be made to be specified sizes and layers as per the requirements of different launching projects.
•  Fonctionnement facile : 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.
• Durable et recyclé : Les airbags marins peuvent être utilisés à plusieurs reprises.
• Grande économie : Comme les airbags marins peuvent être utilisés à plusieurs reprises et que leur coût n'est pas élevé, le lancement ou l'accostage de navires équipés d'airbags marins peut permettre aux chantiers navals ou aux armateurs de réaliser des économies substantielles.

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.
• Longueur effective : 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.
• Diamètre : 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.
• Le nombre de couches : 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.
