Marine Lifting Ship Rubber Airbag

Marine lifting ship rubber airbag

Advantages:
1. High strength
The polyamide cord thread for rubber airbag is produced with high tension reinforced fiber. Acord thread has the strength more than 320N, and the cord fabric has consistent and reliable quality. Our company developed and manufactured high strength airbags with the higher strength steel wires and aramid fiber as skeleton materials on customers' request.
2. Wear resistance and anti-aging
An airbag often works in extreme conditions, for example, it is soaked in the seawater, insolated in the direct sunlight and rolled in send. Rubber airbag is produced with natural rubber in a reasonable formula. The practice proves thatrubber air bag has high wear resistance and anti-aging ability, and the service life is as long as 8-10 years.
3. Good air tightness
Our company uses high quality rubber, etc. As raw materials and the advanced manufacture process to assure that our products have good air tightness, especially air tightness of the assisted floating air rubber assisted floating airbag can keep its pressure for 24 hours at work pressure, with the pressure drop less than 3%

Application:
High-pressure ship launching marine airbags are used for ship launching, ship landing, ship lifting, loading, and floating. They are widely used in cargo boat launching and landing, lifting and moving sunken ships, and salvaging stranded boats. Marine airbags have the benefit of not only saving labor and time, but investment costs. Additionally they are flexible and dependable. The technology of applying pneumatic roller-bags to the launching and landing of ships relieves the restrictions of traditional slide-board technology which is commonly used in building small or medium size ships. Years of trial and error with this technology has increased the ability of launching 100-ton ships to 7, 000-ton ships!
