Our heavy duty air lifting bags are engineered to deliver reliable performance for demanding marine salvage and heavy lifting operations. Built with reinforced synthetic rubber and multi-layer cord fabric, these airbags offer exceptional durability, anti-aging properties and wear resistance, ensuring long service life even in harsh marine environments.
Compliant with ISO 14409 standards, each heavy duty air lifting bag features a high safety factor of ≥5:1, providing maximum stability and security during lifting, beaching and positioning tasks. Available in a wide range of diameters and lengths, they can be customized to meet specific project requirements, with lifting capacities ranging from 10T to 100T per unit.
Whether you’re involved in marine salvage, ship maintenance or heavy object recovery, our air lifting bags are the ideal solution to boost efficiency and reduce operational costs. Their quick inflation and deflation times, combined with excellent temperature resistance (-30°C to +60°C), make them a versatile choice for global marine engineering projects.
When every second counts in marine salvage, our heavy duty air lifting bags are your trusted partner. Designed for quick inflation and deflation, they reduce operational downtime while ensuring maximum safety.
With temperature resistance from -30°C to +60°C and waterproof construction, these bags perform reliably in any climate. Customizable sizes and lifting capacities make them ideal for ship recovery, beaching and heavy object retrieval, helping you complete projects safely and on budget.
What Is a Marine Air Lifting Bag?
A marine air lifting bag is a powerful tool for ship salvage and offshore operations. It lifts grounded vessels and recovers sunken cargo. Furthermore, it works safely in harsh saltwater environments.
Key Features of Our Marine Air Lifting Bags
We build our air lifting bags with reinforced rubber materials. They offer a 5:1 safety factor and high load capacity. In addition, they resist corrosion and extreme temperatures.
Applications in Marine Salvage
Our lifting bags suit small beachings and large offshore recoveries. They inflate quickly to reduce operational downtime. For example, they help salvage teams complete missions faster.
Why Choose Our Marine Air Lifting Bags?
We test every bag to meet marine industry standards. They fit easily on vessels and require minimal maintenance. As a result, they become a reliable partner for global salvage teams.
