Marine Pneumatic Salvage Airbags for Lifting Ship Launching

Product Description

Products DescriptionJerryborg's ship launching airbags are typically made of reinforced rubber layers with a durable outer layer and strong synthetic-cord-reinforced rubber layers. These layers provide the necessary strength and flexibility for the airbags to withstand the immense pressure and weight during ship launching and landing operations.
Ship launching airbags are innovative and flexible maritime tools designed for the launching and landing of ships. These airbags serve as a cost-effective and efficient alternative to traditional launching methods such as slipways or cranes. Advantages
1. High strength
2. Good air tightness
3. Good Abrasion-resistance performance and high ageing resistance 4. New anti-explosion design of end part
5. High kneading & compressing resistance and damping capacityProduct Structure

Application1. Ship Launching & Upgrading
With more than 20 years development in China, Inflatable Upgrading 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, Inflatable Upgrading Airbag is also widely acknowledged by foreign dockyards, shipyards, port/harbour construction companies. Ship launching & upgrading technique with Inflatable Upgrading Airbag is also highly promoted in the markets, such as America, Europe, Southeast Asia. 2 Weight lifting & moving
Marine rubber fend could be applied to caisson lifting, launching, moving and transporting in port constructing projects. 3 Buoyancy Aid & Salvage
Because Inflatable Upgrading Airbag has buoyancy force and load-bearing capacity, it is also widely used in sunken vessel salvage and Buoyancy Aid.
