High quality of natural rubber ship salvage airbag
Product Introduction:
Marine ship airbags are also known as air balloon, inflatable bags, roller bags, air lifting bags, salvage bags. Airbags now are used for ship launching, loading, and floating. They are widely used in cargo boat/ship/vessel launching and landing, lifting and moving sunken ships, and salvaging stranded boats. Air bags have the benefit of not only saving labor and time, but investment costs. Additionally they are flexible, portable, and dependable. Therefore, airbags are widely used in slipping of ships and boats of all sizes.
Applications:
1. Shipwreck salvage
2. Floating bridge and dock construction
3. Rescue and remove of wrecked ship
4. Can be used as pontoons for supporting docks and other floating structure.
Performances:
1. We adopt the most advanced winding process to increase the bearing capacity and moment resistant capacity of airbags.
2. Compared with traditional launching track, the advantages of airbags is more flexibility. They are characterized by high resistance, high gas tightness, ageing resistance, and corrosion resistance.
3. Easy to install and dismantle on the wharf and anchor mast.
4. Long service lifespan.
Constructions:
Ship Launching / Landing Airbags, basic body are consisted of rubber layers, synthetic-cord-reinforced rubber layers, are kind of a cylindrical airbags with hemispherical heads at the both ends. All of these are vulcanized together, and then compress air inside to enable it to roll.
1. Outer Rubber: The outer rubber layer protects the cord layers from abrasion and other external forces. This compound has sufficient tensile and tear strength to withstand any weather condition and hard usage. Standard color is black.
2. Synthetic-net-cord Layer for Reinforcement: The reinforcement cord layers, which are made of Synthetic-tire-cord commonly used in tires, are arranged at ideal angles to hold the internal pressure
and to distribute the stress evenly providing strong efficient reinforcement.
3. End Fittings: End fittings include air tightness swivel and airbags safety air inlet.
