Inflatable Boat Lift Air Bags Boat Landing Airbag Synthetic Tyre Cord Layers

Marine Lift Inflatable Rubber Air Bag Size 1.2m to 12m Boat Landing Airbag

Products introduction

Ship lift air-bags, made of synthetic-tyre-cord layers, are also known as inflatable marine airbags, rolling airbags, lifting air bags, and salvage air bags. They are widely used in launching and landing ships, lifting and moving sunken ships, laying underwater pipes, building mandrels, etc. They have advantages in time saving, labor saving and cost saving. Airbags are safe, reliable and flexible, as well as environment friendly.

The constructure of the airbags are: inner rubber layer , middle reinforced tyre cord rubber layers, and outside protective rubber layer.

The outer rubber layer that covers the outside of rubber 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.The inside rubber layer seals pressurized air inside marine airbags. 
The synthetic tire cord layers are made of polyamid cord which commonly used on tires, that  hold the internal pressure and distribute stress evenly. So they can provide strong efficient reinforcement for the airbags.
 

Performance Calculation Principle of Airbags

The bearing capacity of marine airbags was calculated based on the working pressure and contact area. Working pressure  got upon the burst pressure and safety working factor.As the flexibility of marine airbag the contact area will be affected by some terms which include the carried ship condition, the different position from gravity center during the process of ship launching and pulling. So the bearing capacity of airbags will vary as well as the contact area.
