We have upgraded regular NanHai-ship launching airbags to engineering airbags with ultra-high pressure in order to use them for caisson moving and heavy lifting in harbor construction projects.

Airbags with ultra-high pressure uses high quality rubber and the advanced manufacture process to assure that the largest working pressure up to 1.2Mpa. This kind of ultra high pressure airbags can be used for lifting caissons or heavy structures. Lifting airbags have many advantages compared with the conventional lifting jacks.
