Rubber Airbag is a high-durability pneumatic support and rolling system designed for repeated heavy-load operations in marine and industrial environments. Manufactured from multiple layers of reinforced natural and synthetic rubber, the airbag offers a combination of elasticity, wear resistance, and high fatigue strength that enables long-term reuse under continuous operational cycles.

The internal structure consists of high-tensile tire cord reinforcement arranged in optimized layers to distribute pressure evenly and prevent localized failure. The outer layer is engineered with abrasion-resistant rubber compounds that withstand friction from rough ground, dock surfaces, and ship hulls. This allows the airbag to endure thousands of rolling cycles with minimal material degradation.

Engineered for both efficiency and safety, the Rubber Airbag adapts to uneven surfaces and varying load conditions, providing stable support and controlled movement. Its ability to recover its shape quickly after compression ensures consistent performance during successive operations, making it an ideal solution for high-frequency use in busy shipyards, ports, and offshore construction sites.

A major European shipyard handling frequent small and medium cargo vessels needed a flexible solution to improve throughput without investing in expensive rail systems. Vessels ranged from 1,500 to 4,000 DWT and required rapid relocation between dry docks for maintenance, hull painting, and final launch.

Hongruntong Marine supplied a fleet of reusable Rubber Airbags with optimized diameter and length for these vessels. The airbags were positioned beneath hulls, and internal pressure was carefully controlled to balance weight distribution. The airbag system enabled smooth rolling across concrete slipways, allowing multiple vessels to be handled consecutively with minimal downtime.

During six months of continuous operations, the airbags demonstrated outstanding durability, maintaining structural integrity and elasticity despite heavy use. Vessel relocation efficiency improved by 35%, and the shipyard reported reduced labor costs and minimal hull surface wear. The client emphasized the reliability and repeatability of Rubber Airbags as key contributors to operational productivity.

• Superior Wear Resistance: The outer rubber layer is formulated for abrasion and friction resistance, ensuring the airbag withstands rough surfaces and repeated rolling operations without degradation.
• High Fatigue Strength: Multi-layer reinforcement distributes stress uniformly, minimizing internal material fatigue and allowing safe repeated use under heavy loads over long operational periods.
• Quick Elastic Recovery: Advanced rubber compounds enable rapid shape recovery after compression, maintaining consistent bearing performance and extending service life.
• Operational Versatility: Rubber Airbag adapts to a variety of vessel sizes and ground conditions. Controlled inflation allows fine adjustment of load distribution and movement speed, improving safety and efficiency.

• Shipyard Vessel Relocation: Ideal for high-frequency relocation of small to medium vessels, Rubber Airbag ensures minimal downtime and low maintenance requirements for shipyards with multiple dry docks.
• Maintenance and Painting Operations: Provides stable, reusable support for hull maintenance, painting, and inspection, reducing surface damage compared with rigid supports.
• Offshore Module Support: In offshore or nearshore projects, Rubber Airbag serves as a reliable temporary support and movement system for heavy prefabricated modules under repeated operational cycles.
