50t Underwater Balloon Bags Uv Resistant Fabric Puncture Resistant Abrasion Resistant
Description
Our Parachute-Type Air Lift Bags are perfect for open-water lifting, especially for vertical hoisting of heavy or irregular-shaped objects. These cone-shaped bags automatically position themselves directly above the load, ensuring balanced lifting and reduced risk of tilting. They are widely used in salvage work, underwater construction, and commercial diving operations. With high-lift capacity, durable fabric construction, and pressure relief valves, they combine efficiency, safety, and ease of control—making them a trusted choice for professional marine teams.

FAQ
1. What materials are used?
Reinforced nylon, PVC, or polyurethane with stainless steel/aluminum fittings.
2. What depth ratings are available?
Standard (30m), mid-depth (100m), and deep-sea (300m+) options.
3. How is lift capacity calculated?
Based on bag volume (1m³ lifts ~1 ton in seawater) minus the object’s weight and rigging constraints.
4. Do bags have safety valves?
Yes, automatic pressure relief valves prevent overexpansion.
5. Can they handle sharp objects?
Abrasion-resistant coatings protect against edges, but avoid direct contact.
