Inflatable Rubber Marine Boat Lifting Airbag

Products introduction

Marine 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. 

Features of rubber airbag

1. long lifespan

2. movable and reusable

3. saving investment costs

4. saving labor and time 

Performance Calculation Principle of Airbags

The bearing capacity of marine airbags was calculated based on the working pressure, contact area. Herein, working pressure was got upon the burst pressure and safety working factor.

Because of 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. 

The approximate bearing capacity can be calculated as follows: 

F=PS

S=π x (D1-D2)/2 

Mark:

F: Bearing capacity 

P: Inner pressure 

S: Contact area 

D1: Diameter of airbags when free of loat

D2: Working height of airbags when loaded

 

We are unremittingly committed to making our Lifting and Loading Boat Rubber Airbags better, ensuring that it has stable performance and a long service life. The use of modern management methods, means and tools has become an important condition for the survival and development of enterprises.
