Marine Rubber Airbags are engineered to handle loads from small
fishing boats to vessels exceeding 20,000 tons. Their multi-layer
composite construction of natural rubber and synthetic cord fabric
provides exceptional elasticity and high internal pressure
capacity, ensuring stable performance under heavy loads. The
cylindrical design distributes weight evenly, preventing localized
stress and reducing hull damage during launching or lifting.
Durable Construction with Long Service Life
The airbags are built with multiple layers of wear-resistant rubber
and high-tensile reinforcement, making them resistant to abrasion,
punctures, saltwater corrosion, and aging. Each airbag undergoes
rigorous pressure and leakage tests to ensure airtight performance.
With proper maintenance, Marine Rubber Airbags can deliver reliable
service for over 8–12 years, even under frequent use.
Flexible Cost Effective Deployment
Unlike fixed launching facilities, Marine Rubber Airbags are
portable and require minimal site preparation. They can be rolled
up and transported easily, allowing shipyards and contractors to
set up launching or lifting operations almost anywhere. This
flexibility reduces capital expenditure, shortens project
timelines, and increases operational efficiency.
Enhanced Safety and Stability
Safety is a key advantage of Marine Rubber Airbags. The
high-friction surface and controlled rolling motion ensure a smooth
launch, reducing the risk of accidents. The airbags also provide
excellent shock absorption, protecting both the vessel and the
supporting infrastructure. Detailed operational guidelines and
optional safety accessories—such as anti-slip mats and overpressure
valves further enhance safety during use.
Applications
Ship Launching and Landing
Used to launch new vessels from shipyards into the water or to
retrieve vessels from the water for repair or maintenance. Suitable
for fishing boats, cargo ships, ferries, and offshore structures.
Heavy Lifting and Transportation
Support the lifting and movement of large marine equipment,
floating docks, or pipelines. Their high load capacity and
elasticity allow safe transport over uneven ground or
limited-access sites.
Emergency Salvage and Rescue Operations
Provide buoyancy and lifting power to stabilize or refloat sunken
vessels, overturned barges, or submerged structures during
emergency situations. Rapid deployment makes them ideal for rescue
missions.
Offshore and Industrial Projects
Assist in installing, relocating, or supporting underwater
structures, pipelines, and heavy components in offshore
environments. Their durability and mobility make them suitable for
diverse project needs.

FAQ
1. What sizes and load capacities are available?
Marine Rubber Airbags come in various diameters (0.8m–2.5m) and
lengths (5m–24m) with working pressures from 0.05–0.25MPa. Single
airbags can handle loads from small boats to large vessels
exceeding 20,000 tons when used in groups.
2. How are the airbags inflated and used?
They can be inflated using standard air compressors or portable
pumps. For ship launching, airbags are positioned under the hull,
gradually inflated to lift the vessel, and then rolled to the
water’s edge for launch. Proper coordination ensures a smooth,
controlled operation.
3. What maintenance is required?
After use, rinse the airbags with fresh water, inspect for damage,
and store them deflated in a cool, dry area. With routine
inspections and minor repairs using provided kits, service life can
exceed 8–12 years.
4. Are the airbags compatible with different ground conditions?
Yes. Marine Rubber Airbags can be used on concrete, sand, or
compacted soil. Anti-slip mats or protective sheets are recommended
on rough surfaces to prolong lifespan and ensure safety.
