Marine Rubber Airbag 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.

1. Ship water airbags
The application of marine airbags is less subject to site restrictions and does not require large-scale mechanical equipment, so it can shorten the project cycle and save a lot of money. After more than 20 years of development practice, it has been proven that this product is safe, efficient, green, environmentally friendly, and maneuverable. Launched ships have developed from flat-bottomed boats with a dead weight of tens of tons to large ships with tens of thousands of tons. Practice has proved that the ship airbag launching and launching process is safe and reliable. At present, this technology has been recognized by the shipbuilding and port construction industries at home and abroad, and the airbag launching technology has been widely used in Europe, America, Africa, Southeast Asia and other countries.

2. Air bag for lifting and carrying heavy objects
The high pressure of the inflated rubber airbag is used to lift large heavy objects, and the heavy objects are moved through the rolling of the airbag. Since the airbag lifting and transportation method does not require large mechanical equipment, has low investment, and is simple to install, it is now widely used. In the fields of caisson lifting and transportation, drilling platforms and the lifting and handling of large heavy objects.

3. Air bags for flotation and salvage
After being inflated, the air bag has the advantages of light weight, simple and easy operation, high buoyancy, and resistance to seawater corrosion. It is widely used in the rescue and salvage of stranded and wrecked ships, the launching of caissons, the buoyancy of large pipelines, and the buoyancy of underwater installation projects.

4. Rubber inflatable mandrel
Rubber inflatable mandrel is also called concrete prefabricated hollow slab rubber inflatable mandrel, bridge inflatable core membrane, and rubber inner mold. It is mainly used in the pouring and molding of concrete pre-tensioned and post-tensioned beams in highway bridges and ship engineering. It is also used in culvert sewage drainage projects. The inflatable rubber mandrel is easy to use, economical and durable. It is soft and can fold or curl when it is not inflate. It has enough strength to withstand the pressure of concrete when it is inflated, this is incomparable with any traditional rigid template. It is suitable for drilling holes in reinforced concrete components, including piles, roof trusses, roof panels, beams, construction projects, and water conservancy projects (shipyards, slipways, docks).
