Marine Salvage Pneumatic Air Balloon 2.0m x 15m Ship Lifting Airbag
Luhang marine salvage airbags are tested before shipment following on the below items which are the keypoints of one marine airbag.
>>The appearance of per air bag is smooth, glossy and without blemish such as crack, blister, delamination, pits or impurities.
>> The length and diameter of per air rubber bag are measured with the rated safety working pressure (an tolerance of 3%).
>> The gas-tightness is tested without carrying any load as per ISO 14409. The pressure loss is less than 5% of rated working pressure within 24 hour.
The ship marine salvage airbags mouths are installed with metal valves mounted for airbag pulling.
Ship Lifting
A] Tie the winch with wire rope to the ship hull
B] Choose the bow at the bottom of the better position to fill in one or more rubber airbags, when lifting to a certain height, will be the first to reach the ship under the winch tows. Barge bottom flat type, such as airbags and bottom contact area large, if the ship hull weight was small, as long as there is difficulties, from the first feeding can be from one side to the other string into a airbag.
When the hull weight is bigger, according to certain spacing increase 1 to 2 or more air bags, until lift up first. First a "v" shaped powerboat, often because of the air bag and the bottom contact area is too small lifting force is not enough, would require airbag back, sometimes want to back a quarter of the captain to lift up the bow.
C] Start the winch, the ship started to move, one by one according to the requirements of air bag placed spacing feeding airbags, always pull the boat to the berth.
D] Lifting vessels in conjunction with the lifting air bag together, playing hard block, withdraw the air bags.
