Ship Launching Airbag

Advantages:

  1. 1. Ship launching airbag overcomes the shortcomings of the fixed launching track, which limits the productive capability of the small and medium sized shipyards.
  2. 2. Using the ship launching airbag becomes a flexible launching technology. It has the advantage by saving time and labor.
  3. 3. The airbag has the characters of flexibility, reliability and safety in ship launching operation, and also economic.
BASIC INFO SPECIFICATION PRODUCTION PROCESS APPLICATION

Ship launching airbag is also known as inflatable marine airbag, roller bag, air lift bag, salvage bag and ship launching balloon, which is made of synthetic-tire-cord reinforcement layers and rubber layers. It is widely used in cargo boat launching and landing, lifting and moving sunken ships, installation of underwater buoyancy aid, and salvaging stranded boats. Ship launching airbag is less limited by space, no large mechanical equipment, can shorten the working period and save the unnecessary cost. Additionally they are flexible, portable and dependable. Therefore, Airbags are very popular with shipyard, ship owner and marine supplies company now.

Features of Marine Airbags:

  •  High bearing capacity 
  •  High resistance to knead ability
  •  Optimization of structural layout
  •  Durable anti-aging abilities and wear resistance
  •  Higher flexibility and shock absorption ability

Airbag heads: conical parts connecting the body and the mouths of the air bag.
Airbag mouths: either metal valves mounted on both ends of the air bag for inflating with air or a valve on one end and a metal lug on the other end used to haul the air.

The length of ship launching airbag is specified by the customer when it is manufactured.                                                  Besides, we will choose a reasonable size for the customer, according to the information provided by the customer, such as the type of vessel, LOA of ship, vessel's actual launched weight.

Ship launching airbag overall winding structure uses cross whole intertwine technology, which make its overall structure more reasonable, texture clear.
