उत्पाद विवरण
Cylindrical Underwater Air Lift Bag
The cylindrical Underwater Air Lift Bag is an advanced marine buoyancy and lifting solution designed for integrated engineering applications, emergency recovery operations, and complex underwater construction environments. Manufactured from high-performance multi-layer synthetic fabric reinforced with industrial-grade polyurethane and PVC composite coatings, it provides excellent resistance to abrasion, seawater corrosion, UV exposure, and long-term fatigue under cyclic loading.
The cylindrical geometry ensures stable vertical lift performance and balanced load distribution even under irregular underwater conditions. Each unit features reinforced lifting points, high-pressure inflation valves, quick-connect fittings, and multi-stage safety release systems for precise buoyancy control and operational safety.
With lifting capacities ranging from 2 tons to over 400 tons, the system is suitable for both light-duty emergency response and large-scale offshore engineering projects. It is widely used in salvage operations, marine infrastructure installation, harbor engineering, and underwater maintenance tasks.
Case Study: Emergency Vessel Recovery & Harbor Clearance
In a European commercial harbor, a 1,800-ton cargo vessel partially sank after a collision during docking operations, blocking a major shipping channel. The situation required immediate clearance to restore port operations, with strict limitations on environmental impact and operational downtime.
Hongruntong cylindrical underwater air lift bags were rapidly deployed as part of an emergency response system. A modular lifting configuration was used to stabilize the vessel and gradually restore buoyancy. The controlled inflation process allowed engineers to lift the vessel in phases, ensuring structural integrity while preventing secondary damage.
Within 48 hours, the vessel was successfully refloated and moved to a repair zone. The harbor resumed partial operations shortly after, significantly reducing economic losses. The client highlighted the system's rapid deployment capability, operational stability, and effectiveness in emergency marine recovery scenarios.

Key Features
  • Integrated Modular Lifting System for Complex Engineering Tasks
    The air lift bag system is designed for modular integration, allowing multiple units to be combined for scalable lifting capacity. This flexibility enables engineers to design customized lifting configurations for complex underwater structures, uneven loads, and large-scale salvage operations.
  • Rapid Deployment for Emergency and Time-Critical Operations
    Engineered for fast response scenarios, the system features quick-connect inflation valves and simplified rigging interfaces. This allows deployment within a short time frame, making it highly effective for emergency vessel recovery and disaster response operations.
  • High Performance Material System with Long-Term Fatigue Resistance
    Constructed using reinforced composite fabric layers that provide excellent resistance to cyclic loading and long-term mechanical fatigue. The material maintains structural integrity even under repeated inflation and deflation cycles.
  • Multi-Level Safety Architecture with Controlled Buoyancy Management
    Safety is enhanced through a multi-layer protection system including overpressure relief valves, controlled exhaust mechanisms, and reinforced connection points. This ensures stable and predictable buoyancy adjustments during lifting operations.
