5m x 5m Buoyancy Air Bag 8T Load Lightweight Non Slip Surface
Descripation
Designed to meet the demands of offshore engineering, underwater salvage, and ship maintenance, Hongruntong Marine’s parachute-type lifting bags deliver precise vertical lift with reduced lateral drift. The open-bottom design allows for smooth water displacement, ensuring stable ascension.
Our lifting bags feature pressure relief valves and reinforced lifting belts, providing added safety during complex underwater operations and minimizing the risk of over-inflation or load imbalance.
