Open parachute lift bag An underwater air lift bag with an open bottom.
The buoyancy can be easily adjusted by controlling the amount of air infused into the bag through a manual air dump relief/dump valve.
Structural composition:
1) Dump line is tied to the exhaust valve of the parachute lifting bag and can be operated by the diver to open or close the exhaust valve to control the underwater air lifting bag.
2) Inverter line is used to pull down the parachute lifting bag to release the air in the bag when the parachute lifting bag accidentally detaches from the lifted weight.
3) Web sling is a set of slings that connect the bottom of the lifting bag and converge to the lifting ring.
4) Restraining or hold-back line is a rope used to prevent the lifted weight from rising uncontrollably with the underwater air lifting bag.
5) Dead man anchor is a fixed structure or independent anchor point used to restrain the load.
6) Manufactured attachment point is the connection point for the top of the parachute lifting bag to connect the overturning rope.
Safety and high quality
• Overall WLL is 5:1, and the sling WLL is 7:1.
• Equipped with multiple pressure relief valves to ensure safety.
• High-performance structural fabric canopy.
• RF welds.
• Tapered design at the ends prevents stress and over-inflation at the end points.
Convenient and flexible design
• Ideal for extremely shallow water.
• Buoyancy of single or multiple units can be increased or decreased as required.
• Webbing safety harness includes multiple fixed steel lifting loops with spacer straps.
• Integral end ropes to prevent rotation.
• Integral carrying ladder.
• 2 x 3/4" BSP standard inflation/deflation valves with 316 stainless steel male quick adaptors as standard.
• Leafield marine high-speed pressure relief valves (PRVs).
Optimized deployment
• Air can be charged or released to one or more units to facilitate placement or change of deployment location.
• Optimized horizontal deployment
Product Specifications:
• Lifting capacities are available in a variety of different specifications from 250 kg to 50 tons.

Understand the conditions of use
• The use of underwater air lift bags should meet the basic regulations and environmental requirements for diving safety.
• There should be no underwater explosions, pollution, obstacles, high-pressure water jets, electric shocks, and other factors that endanger the safety of divers.
• Sufficient surface and underwater lighting should be provided, and the illumination should not be less than 200 lx
