Marine Salvage Bags UV Resistant Abrasion Corrosion Resistant Easy Storage

Description

The Pillow Type Underwater Air Lift Bags are advanced inflatable lifting devices designed for precision underwater operations. These bags combine high-strength materials, robust design, and safety features to provide controlled lifting and flotation of submerged objects. Their pillow-shaped construction distributes air pressure evenly, minimizing tilting and enhancing stability during vertical ascent. Equipped with overpressure relief valves and reinforced attachment points, these air lift bags are ideal for complex salvage, construction, and emergency buoyancy tasks.

Case Study
 

During a recent underwater infrastructure project, a team needed to lift a 5-ton concrete beam from a riverbed at a depth of 18 meters. The engineers deployed three 2-ton Pillow Type Air Lift Bags, each carefully positioned beneath the beam. The sequential inflation technique allowed the beam to rise gradually, avoiding sudden movements that could endanger divers or damage the beam. Overpressure valves ensured safety by releasing excess air automatically. Once at the surface, the beam was stabilized and transported for further installation. This project showcased the precision, stability, and reliability of pillow-type lift bags in handling heavy, irregularly shaped objects in challenging underwater environments.

Features

Exceptional Lifting Strength and Buoyancy Management
The Pillow Type Air Lift Bags offer superior lifting capacity with precise buoyancy control. Each bag is designed to distribute lifting forces evenly across its surface, reducing the risk of toppling. Sequential inflation methods allow operators to lift uneven or asymmetrical objects safely. The integrated overpressure relief valves provide an automatic safety mechanism, preventing dangerous air pressure buildup and ensuring a smooth, controlled ascent. These features make them suitable for delicate salvage operations, underwater construction, and heavy equipment recovery.

Robust and Long Lasting Construction
Constructed from reinforced PVC-coated fabric with high-strength seams, these lift bags withstand abrasion, punctures, and UV exposure. The materials are carefully selected to maintain flexibility under varying pressures and temperatures, ensuring consistent performance in harsh underwater environments. Reinforced attachment points and seams guarantee that the bag retains structural integrity during heavy lifting tasks. This durability reduces downtime, repair costs, and enhances overall operational efficiency, making these bags ideal for professional marine operations.

Versatile Deployment and User Friendly Design
These lift bags are lightweight, compact, and easy to transport, simplifying logistics for remote underwater projects. Quick-connect inflation systems and integrated harnesses allow rapid setup and precise placement. Operators can deploy bags individually or in groups to accommodate loads of different shapes and weights. This flexibility is especially valuable in underwater construction, salvage, or emergency scenarios, where conditions can change unexpectedly and fast deployment is critical.

Enhanced Safety and Operational Reliability
Safety is central to the design of Pillow Type Air Lift Bags. Overpressure relief valves, reinforced attachment points, and stable pillow shapes minimize the risk of accidents or uncontrolled movements. The high-visibility color and durable coating enhance underwater monitoring. Combined with careful deployment and controlled inflation, these safety features ensure reliable and secure lifting operations, protecting both divers and cargo.

Applications

Salvage and Recovery Operations
Pillow Type Air Lift Bags are essential for recovering sunken vessels, heavy machinery, and underwater debris. Their controlled lift and high capacity ensure objects are raised safely without causing additional structural damage.

Underwater Construction and Positioning
These lift bags assist in positioning large components such as bridge segments, pipelines, and subsea platforms. Their stability and ease of deployment enable precise maneuvering, even in challenging underwater conditions.

Emergency Flotation and Rapid Response
In emergencies, Pillow Type Air Lift Bags provide immediate buoyancy support for stranded vessels, submerged cargo, or flooded docks. Quick inflation and reliable lift capacity make them indispensable for rescue and maritime safety operations.
