Customizable Size and Load Capacity
Air bags can be tailored in diameter, length, and reinforcement
density to meet vessel-specific weight requirements. This
scalability allows deployment across a wide range of ship sizes
from small patrol boats to ferries and offshore support vessels.
Enhanced Safety Through Controlled Deformation
The multi-layer reinforcement ensures predictable rolling and
compression behavior, reducing the risk of hull instability or
tipping during launch or transport.
Durable Surface for Harsh Environments
Outer rubber layers resist abrasion from concrete, steel, and
gravel surfaces, as well as UV radiation, seawater, and chemical
contaminants, ensuring long service life and minimal maintenance.
Quick Deployment and Ease of Operation
Air bags are lightweight relative to traditional rollers and can be
moved or repositioned by standard lifting equipment. Inflation and
deflation are simple, enabling faster project timelines and
flexible operations in constrained spaces.
Applications
Ship Launching and Hauling
Ideal for rolling vessels on land or toward floating docks, even in
areas without permanent slipways or traditional infrastructure.
Heavy Lift Operations
Useful for lifting and transporting large industrial modules,
prefabricated marine structures, or offshore equipment safely and
efficiently.
Underwater Buoyancy Support
Provides controlled flotation for submerged installations, pipeline
handling, or salvage operations, offering adjustable buoyant force
with predictable stability.

FAQ
1. Can air bags be used for vessels with unconventional hull
shapes?
Yes, the bags’ flexible deformation allows them to conform to
varying hull geometries while distributing load evenly, preventing
stress points.
2. How do I determine the number and placement of air bags?
Hongruntong engineers perform calculations based on vessel weight,
hull dimensions, and ground conditions to provide precise placement
for optimal stability.
3. What environmental conditions can the air bags withstand?
They are resistant to seawater, UV radiation, abrasion, oils, and
chemical contaminants, suitable for outdoor and marine
environments.
4. Is it possible to reuse air bags for multiple projects?
Yes, with proper handling, inspection, and maintenance, air bags
can be reused multiple times while maintaining performance and
safety.
5. What safety precautions are recommended during operations?
Operators should monitor inflation pressures, inspect bags for
damage, avoid sharp objects on deployment surfaces, and use
synchronized winching systems to control vessel movement.
