Hongruntong Marine Rubber Airbags are advanced pneumatic lifting and launching solutions engineered for demanding marine, offshore, and heavy industrial applications. Manufactured from premium-grade natural rubber and reinforced with multiple layers of high-strength synthetic tire cord fabric, these airbags provide exceptional load-bearing capacity, superior elasticity, and long-term durability under challenging working conditions.
Designed to meet the operational requirements of modern shipyards, marine engineering contractors, and heavy equipment transportation companies, Hongruntong Marine Rubber Airbags have become a reliable alternative to traditional slipways, fixed launching systems, and expensive heavy lifting equipment.
A leading private shipyard in Indonesia successfully launched an 18,500 DWT multipurpose cargo vessel using Hongruntong Marine Rubber Airbags. Despite having no permanent slipway or heavy-capacity gantry crane, the shipyard achieved a safe and efficient launch through our engineered airbag solution.
Twenty-six airbags measuring 2.0 meters in diameter with 18-meter effective working lengths were deployed. The entire launching process required approximately forty-five minutes, with site preparation completed within three working days. The project demonstrated substantial cost savings of over sixty percent compared to traditional slipway construction.

Advanced engineering technology combines premium natural rubber with multiple layers of high-strength synthetic tire cord fabric, creating a reinforced structure capable of supporting heavy marine vessels while maintaining excellent flexibility and stability.
Specially formulated rubber compounds provide superior abrasion resistance and weather protection. Advanced anti-aging technology improves resistance against UV radiation, ozone exposure, oxidation, and environmental degradation.
Simple operation and flexible application requiring less infrastructure investment. Lightweight and portable design enables quick deployment in different locations with high reusability for multiple projects.
Designed with multiple safety features and supported by customized engineering recommendations. Comprehensive technical documentation and professional support throughout the product lifecycle.
Hongruntong Marine supplies rubber airbags in various diameters, effective lengths, and reinforcement layers. Standard products are available for common applications, while customized specifications can be developed according to project requirements.
Airbags are placed beneath the vessel according to the recommended arrangement plan, inflated to working pressure, and roll beneath the hull during launching to provide continuous support while transferring the vessel safely toward the water.
Yes. With proper operation, regular inspection, and correct storage conditions, the same airbags can support many launching and transportation projects.
Yes. Specially developed rubber materials provide resistance against seawater, UV radiation, ozone, humidity, and temperature changes for use in various climates and marine environments.
Each rubber airbag undergoes pressure testing, airtightness testing, dimensional inspection, and quality verification. Products meet international standards including ABS, BV, KR, LR, GL, NK, RINA, DNV, and RMRS certifications.
