Marine Salvage Airbags
Marine Salvage Airbag is developed by Hongruntong team according to the requirements of salvage engineering. Underwater fishing engineering generally has the characteristics of complex construction, high cost and strict requirements for equipment and personnel. The fishing airbag completely overcomes these shortcomings. Because of its convenient use, simple operation, buoyancy and other advantages, it is recognized by the majority of engineering teams.
Salvage Airbag is mainly used for sunken ship salvage, floating bridge, wharf construction, rescue and removal of ships in distress and stranded. The design of fixing method of salvage airbag is changed according to different rescue projects, which is very important to ensure successful rescue. Salvage airbag is attached with fixed lifting point, which can be fixed together with objects to be rescued by rope.
Each airbag can easily lift more than 200 tons in the water. Practice has proved that the airbag is an economical and practical tool in the process of salvage.
