Rubber Ship Launching Airbag Inflatable Ship Lifting

Inflatable Ship Lifting Rubber Airbags Ship Launching Airbag Rubber Airbag

ship launching or landing depending on Marine Airbags is an innovative technology hav ing utomost bright prospect in maritime fields. This kind of "Flexible Launching Technology" is becoming popular around the world because of its cost effective and convenient advantages. Marine airbag for ship launching overcomes the restrictions of traditional slipway launching methods which
is commonly used in small or medium size ship'building.

Salvage Rubber Airbag is made of rubber material, which is different from the metal material another salvage equipment. It can produce water buoyancy, the overall sealed, submerged in water can bring huge buoyancy, So it is mainly used for salvage sunken Vessels, weight lifting and moving and some other emergency rescue projects etc.

Through filling the compressed air to produce buoyancy, then using buoyancy to salvage, easy operation and safe and reliable.
In addition to hang a vessel in a fixed position or connected with lifting jack of the bottom of Vessel, Marine Rubber Airbags also can be placed inside the Vessel cabin, through filling out the cabin water to provide buoyancy.

The use of marine rubber airbags helps to remove the hindrance of using tows and tugs as launching and landing instruments. Moreover since the airbags use synthetic rubber and a high defined system as their core design, it has become easy to use such airbags for any ship that has a DWT (Dead Weight Tonnage) of less than 55,000.

Airbag Size:

Ship transferring from the building area to the slip is produced approaching the deflated air bag under the vessel and inflating with compressed air. The launching is made on the air bags used as the rollers. This launch can be both uncontrolled and controlled. In the latter case the launching speed is regulated by the traction mechanism which is located at the head of the slip.

The distance between the air bags depends on the light-ship, the length and width, but not more than 6 meters from the bag centers. To install the bag the space at least 25 cm in height and width at least the half of the circumference of the air bag is required.

Air bag (hereinafter - AB) for upgrading and launching of vessels and dragging heavy dimensional structures with flat basis (without protrusions). Also suitable for use as a pneumatic jack. Pneumatic bags are intended for ship transportation, repair and painting.

Pneumatic bag has two threaded bushings on the tapered ends, one of them is connected to the pressure control unit and the valve for the compressed air, another end is equipped with eyebolt to drag the bag during the operation

Air bags also allow for the landing of vessels in locations previously restricted only to dry docks. Years of trial and error with pneumatic roller bag technology has increased the ability of launching 100-ton ships to 13,500-ton ships!

4-layer bags that are 1.5m dia x 15m long for example contain a rubber content that is not less than 51%. The air-bags can safely hold 156-tons with a safe working pressure of 0.08MPa while rolling. When standing still the highest lifting pressure is 0.10MPa while holding 194-tons.

6-layer bags that are 1.5m dia x 15m long for example contain a rubber content that is not less than 51%. The air-bags can safely hold 234-tons with a safe working pressure of 0.12MPa while rolling. When standing still the highest lifting pressure is 0.14MPa while holding 272-tons.

Rubber Airbag Safety Precautions

1) Strictly control the use of pressure
2) Surface contact with the air bag cannot have sharply pointed a blur, prevent prick the airbag
3) Try to avoid air bag length direction of distortion
4) Long time not to use or repaired airbag, pressure test is required before using again; Often use airbags,test once a year.
5) Drag the airbag on the ground balloon is prohibited
