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.
