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.
