Boat Lift Inflatable Rubber Air Bag Size 1.5m to 12m Ship Lifting Airbag

Products introduction

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

The out side 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 cord layers are made of synthetic tire 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 air bags was calculated based on the working pressure, contact area. Working pressure was got upon the burst pressure and safety working factor.Because of the flexibility of marine air bag 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 air bags will vary as well as the contact area.
