Heavy Lift Marine Airbags Superior Strength Weather Resistant High
Floatation
Description
Marine Rubber Airbags revolutionize ship launching and recovery
with their high buoyancy and flexibility. Designed in sizes from
1.5m to 5m, they support vessels weighing 10–200+ tons,
distributing weight evenly for a smooth launch. Made from
reinforced rubber and nylon layers, they resist abrasions, oil, and
UV damage. Unlike traditional methods, these airbags reduce
infrastructure costs, require minimal manpower, and allow for
precise control during operations. Their quick-deployment feature
speeds up workflows, making them essential for shipbuilders, naval
bases, and repair docks.

FAQ
1. Can they operate in extreme temperatures?
Yes, functional from -40°C to +80°C (-40°F to 176°F) without
performance loss.
2. How are they inflated?
Using high-flow air compressors (6–12 bar) via our quick-connect
valve system (30% faster inflation).
3. Are repairs possible?
Yes, we provide custom repair kits with vulcanizing patches for
field fixes.
4. Do you offer certifications?
All airbags are DNV-GL/ABS/CCS certified with full material
traceability.
