Marine Lift Bag Powerful Buoyancy Quick Inflation Durable Design
The Boat Lift Helper is a versatile lifting solution designed to make underwater lifting operations safer and more efficient. Engineered for maximum buoyancy control and stability, it enables operators to lift boats, submerged structures, or marine equipment with minimal effort and risk. Its robust construction ensures reliability even in challenging underwater conditions.
In 2023, a diving team in Rotterdam successfully used 10 Boat Lift Helper units to lift and stabilize a 20-ton sunken ferry section. By gradually inflating each bag and securing the load with reinforced straps, they achieved a controlled ascent with zero sway, allowing the vessel to be safely towed for repairs. This operation demonstrated the product's efficiency and precision in heavy-lift scenarios.
