Buoyancy Pontoon Marine Airbags Building or Lifting Rubber Airbag for Ship Dry Docking
Product Description
6000 years ago, our ancestor begin to use log-rolling method
to lift and move weights, which is still widely used in daily
production and actual life nowadays. Marine rubber airbag is
designed with soft rubber to lift and carry weights, based on
log-rolling method.
Marine rubber airbag is an innovative product of Chinese own proprietary intellectual property rights. It has wide application like ship launching & upgrading, caisson lifting & moving, heavy weights lifting, underwater-engineering buoyancy aid. The marine rubber airbag is not limited to space and heavy machinery, which could efficiently shorten the construction period and save lots of funds.
Advantages
1. High strength
2. Good air tightness
3. Good Abrasion-resistance performance and high ageing resistance
