Product Detail

Technical parameter

Marine airbag is an innovative product with independent intellectual property rights in China. It has a wide range of applications such as ship launching and landing, caisson lifting and moving, heavy lifting, buoyancy aid for underwater engineering. The airbag is not limited by space and heavy machinery, which can effectively shorten the construction period and save a lot of money.

Application scenario

1 、Ship Launching & Upgrading

With more than 20 years development in China, 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, Airbag is also widely acknowledged by foreign dockyards, shipyards, port/harbour construction companies. Ship launching & upgrading technique with Airbag is also highly promoted in the markets, such as America, Europe, Southeast Asia.

Packaging and transportation of airbags

According to the provisions of the People's Republic of China shipping industry standard CB/T 3795-1996, the packaging, transportation and storage of Marine airbags should follow the following standards:

1. Packaging

After folding, bind and pack with plastic woven bag.

2. Transportation

When the air bag is transported in short distance, it should be carried by lifting, lifting, inflating state rolling, etc., and it is strictly prohibited to drag it on the ground.

During long-distance transportation, the air bag should be folded and fixed on the tray, with a liner underneath and wrapped with a winding film outside.
