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.
