Construction Features of Airbags
Ship moving airbag for ship launching have the best designed structure which consists of five different functional membranes in rubber layers.
1) Outer Rubber Layer
The outer rubber layer that covers the outside of marine airbag to protect under layers from abrasion and other external forces. This compound has sufficient tensile and tearing strength to withstand any condition and hard usage.
2) Inner Rubber Layer
The inner rubber layer seals pressurized air inside marine airbags.
3) Synthetic-Tire-Cord Layer as 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 distribute stress evenly. So they can provide strong efficient reinforcement.
To recommend you best rubber airbag size
Before to provide suitable airbag size and quantity for your ship, please provide below information:
1.Ship length,width and weight.
2.Type of ground ship is built on? (Dirt, concrete, etc.)
3.Type of ship?
4.Depth in meters of the water where the ship first enters the water?
5.What's the angle degree of slipway? (Land, not under water)
6.Please provide the low/high tide schedule at site.
7.The working height? (The block stand height under the ship)
8.Distance from bottom of propeller to the water level?
9.Distance from back of ship (in dry dock) to the water entry point?
*If possible, please provide photos of the launch area.
Material of ship moving airbag
An rubber roller airbag is to be constructed of an outer rubber layer, one or more synthetic-tyre-cord layers, and an inner rubber layer. The arrangement of synthetic-tyre-cord reinforcement layers is shown in the picture below, all materials shall be vulcanized firmly.
Advantages of ship moving airbag
1. Various sizes.
2. Provide repairing kit.
3. Long service life(6-8 years).
4. Reused many times.
5. Good wear resistance.
6. Good raw material.
7. Harmless to the enviroment.
8. Cheaper and portable.
Safety Precaution of ship moving airbag
1.Over pressure Control:
Must use the right pressure when use. 2.The Landing Slipway Requirements:
The landing ground should be clean and stable. 3.Avoid Sharp Objects(most important):
Sharp objects can easy damage the airbags. 4.Avoid Distortion And Overweight:
Avoid distortion in the length direction during rolling and avoid overweight load after gas charging.
