Rubber Airbag is a high-performance pneumatic solution engineered for heavy-load handling, vessel movement, and structural support in marine and industrial applications. Manufactured from premium natural and synthetic rubber compounded with high-strength fabric reinforcement layers, it provides optimal elasticity, durability, and load-bearing capability.
Each airbag is designed to withstand extreme compression and deliver stable performance under dynamic operational conditions, capable of evenly distributing heavy loads over large contact areas to significantly reduce localized stress on hulls, steel structures, and industrial equipment.
A South American shipyard faced challenges with simultaneous launch scheduling for cargo vessels ranging from 2,500 to 8,000 DWT. Traditional launching rails were insufficient due to space limitations and high labor costs.
Hongruntong Marine supplied custom Rubber Airbags specifically designed to match the vessels' displacement and hull geometry. The airbags were deployed with optimized spacing to ensure even load distribution, with internal pressure adjusted incrementally for controlled, smooth rolling movement.

* Other sizes can be produced following client's requirements
Rapid deployment, adjustment, and repositioning without extensive infrastructure. Conforms to uneven surfaces, reducing setup time and labor requirements. Internal pressure control enables fine-tuned movement with precise speed and alignment.
Eliminates need for rails, cranes, or hydraulic platforms, reducing capital expenditure. Long service life and reusability provide lower cost per operation with reduced labor hours and operational costs.
Multi-layer reinforced structure evenly distributes heavy loads over wide contact areas, minimizing point stress. Air-filled design absorbs shocks and vibrations, increasing operational safety and preventing damage.
Constructed from abrasion-resistant and UV-stabilized rubber for harsh marine and industrial environments. Reinforced fabric layers provide high tensile strength and fatigue resistance with resistance to saltwater, heat, and cold.
Depending on vessel size and airbag specifications, deployment can often be completed within a few hours, significantly faster than rail or crane-based systems.
With proper handling, inspection, and maintenance, each airbag can last for hundreds of cycles, maintaining consistent load-bearing performance.
Yes. Hongruntong Marine offers fully customized designs, including diameter, length, reinforcement layers, and pressure ratings to fit unique operational requirements.
The airbag evenly distributes heavy loads, absorbs shocks, and reduces point stress on vessels or structures. Controlled inflation allows precise movement, minimizing the risk of hull or structural damage.
Yes. The materials are resistant to saltwater corrosion, UV degradation, and temperature extremes, making them suitable for long-term marine and industrial applications.
