    Caisson Moving Airbag

    The caisson moving airbag is a specific airbag used to move the built bridge caisson on land. It also be called industrial airbag. The caisson is a kind of pier used in the construction of a cross-sea bridge. The caisson moving airbag follows the ancient method of moving heavy objects by rolling wood. After prefabricating the caisson on the pedestal, the lifting airbag is stuffed into the trench at the bottom of the caisson, and the caisson is inflated to lift the caisson. After that, the caisson is pulled by the tugboat and arrange in the ocean. The caisson moving airbag has a large contact area with the ground, and the bearing capacity is evenly distributed. It is very adaptable to the site and a very popular transport equipment in currently ocean construction. The difference between the caisson moving airbag and the ship launching airbag is the working pressure. Therefore, the ship launching airbag cannot replace the caisson moving and lifting airbag.
