Airbag Launching technology was developed based on traditional slipway launching mode, it used flexible Marine Airbag to replace slipway and sliding plates, so as to overcome many short comings of traditional slipway launching mode. Flexible airbag is like elastic cushion to bring the ship free pitching during the launch course and the pressure under hull bottom to be moderated due to larger flexible contact area, which protects the hull structure and surface paint against damage. CHANGLIN ship launching rubber airbags are developed especially for ship launching technology, which process extremely high bearing capacity, resistant to wear and to salt water corrosion, its main function is for transporting ship to launch or upgrade.
the applications of airbags except ship launching can widely use to transport large-size construction modules, to salvage sunken ships and service and as a container for storing liquid and gas and as a pontoon to building bridges and pipelines and so on.
