Nylon Cord Winding Ship Airbag , Marine Airbag For Ship Launching
Ship launching rubber airbags technique was found to be versatile and flexible in marine engineering fields. Rubber Airbags can lift up heavy like jacks and move it forward,act as pneumatic rollers. Airbags can roll over pits and knuckles, so they have less demands of the ground or ramp. Different from rigid trolleys, launching airbags can be compressed at different ratio, thus they can absorb the impact energy emerges in some structure launching projects.
Product Feature
1. Special synthetic tire-cord layer material
Our rubber airbags are made with special sunthetic tire-cord layers, which have much better performance than those made with PVC coated fabrics.
2. High-Pressure Design
Our rubber airbag has a maximum working pressure of 0.25MPa . That means that they can be used under 25m water-depth.
3. Holistic Screw Type Enlacing Salvage Airbags
Our rubber airbags are a totally enclosed tube with cone ends. It is manufactured using Holistic Screw technology.This design ensures that there aren't any welded seams. This makes them stronger than RF welded airbags.
4. Equipped with accessories
Our Salvage-Bags are equipped with nylon straps and shackles with 6:1 safety factor.
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
