Boat Lift Inflatable Rubber Air Bag Size 1.5m to 12m Ship Lifting Airbag
The boat lift rubber airbags been used for ship launching has been lasting for decades, which generally accepted that originated from China.A shipyard that using air bags to replace chute and skateboard,to overcome the many shortcomings of traditional ship launching.
The airbag is featured with energy conservation and environment protection, reasonable structure and durability. The airbag body is round and smooth and the heads are safe and reliable. Our airbags have been widely used domestically and overseas. The application of airbag has little specific site constraints and it does not large machinery or equipment, thus using airbags to launch or land ships can shorten project period and financially save a large amount.
Products introduction
The constructure of the airbags are: inner rubber layer , middle reinforced tyre cord rubber layers, and outside protective rubber layer.
The out side rubber layer that covers the outside of rubber airbag to protect under layers from abrasion and other external forces. This compound has sufficient tensile and tearing strength to withstand any condition and hard usage.The inside rubber layer seals pressurized air inside marine airbags.
The cord layers are made of synthetic tire cord which commonly used on tires, that hold the internal pressure and distribute stress evenly. So they can provide strong efficient reinforcement for the airbags.
Performance Calculation Principle of Airbags
The bearing capacity of marine air bags was calculated based on the working pressure, contact area. Working pressure was got upon the burst pressure and safety working factor.Because of the flexibility of marine air bag the contact area will be affected by some terms which include the carried ship condition, the different position from gravity center during the process of ship launching and pulling. So the bearing capacity of air bags will vary as well as the contact area.
