Inflatable Heavy Lifting Rollers Ship Launching 1.5m X 9m (8
Layers) Marine Rubber Airbags
Introduction
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.
Technical Requirement
According to CB/T 3795--1996, marine rubber fender should meet the
following requirements.
Diameter & Effective Length Deviation: ±2%
Total Length Deviation: ±4%
- Amount of Elastic Deformation: diameter deformation amount ≤ 5%
under 1.2 times working pressure.
- Safety Factor: >4.5
- Air Tightness: depressurization < 5% after 1hour inflation
- Surface Quality: fairing line shape, no crack, no bubble, no double
skin, no impurities, no distinct dirt and other apparent defect.
- Anti-explosion design of end part.
Manufacturing Technology
Whole Intertwine Technology
"HENGER" Airbags overall frame structure uses cross whole
intertwine technology, the overall structure is more reasonable,
texture clear, no juncture, high loads, more safety than lap
technology (roller), more than 20% bearing capacity.
Framework
“HENGER” airbag structure are consist of the outer rubber +
synthetic cord reinforced rubber layers.Its shape characteristics:
central body cylindrical + tapered on both ends. Cord layers:
4,5,6,7,8,9,10,11,12 layers.
Application
- Ship Launching & Upgrading
With more than 20 years development in China, marine rubber airbag
is proved to be the most reliable and stable technique for ship
launching & upgrading. It is applicable from tons of flat board to
ten thousand tons of huge ship. Meanwhile, marine rubber airbag is
also widely acknowledged by foreign dockyards, shipyards,
port/harbour construction companies. Ship launching & upgrading
technique with marine rubber airbag is also highly promoted in the
markets, such as America, Europe, Southeast Asia.
Marine rubber fend could be applied to caisson lifting, launching,
moving and transporting in port constructing projects
Because marine rubber airbag has buoyancy force and load-bearing
capacity, it is also widely used in sunken vessel salvage and
Buoyancy Aid.
