Florescence Boat Marine Rubber Airbags For Ship Launching And Docking
Florescence ship rubber airbags can be used to launch and land a ship up to 100,000DWT. Comparing to the traditional slipway launching method, the ship rubber airbags are much convenient, because ship airbag can launch a ship at any seaside, so there's no need to worry about the construction of launching facilities; besides, the marine airbag need little maintenance and can be used repeatedly. Need no more than air compressors, winches and ropes.

How do airbags work?
All you need is a slipway that is free of sharp objects, a slipway winch together with accessories like steel wire rope & shackles to provide the pulling force needed, and some airbags. Then, deflated airbags are inserted under the hull of the vessel and inflated to lift the vessel. The airbags are designed with great bearing capacity & facilitates the vessel into the water (or out of the water, depending on use) due to its ability to roll.
Acceptance test for ship rubber airbag
Our test the ship rubber airbags purchased based on the test items indicated below:
* The appearance of the airbag is free from defects such as blemishes, bubbles, cracks, etc.
* The diameter, length and working pressure of each air bag need to be tested before shipping.
