Rubber Airbag is a heavy-duty pneumatic marine solution designed for large-load handling, vessel movement, and structural support in demanding maritime and industrial environments. Manufactured from multi-layer reinforced rubber composites, it combines high elasticity, superior load-bearing capacity, and excellent durability under repeated compression cycles.

The product is engineered using an inner airtight rubber layer, multiple layers of high-tensile synthetic cord reinforcement, and an outer abrasion-resistant rubber cover. This structure allows the airbag to evenly distribute loads, reduce point stress on hull structures, and maintain stable deformation under high pressure.

A coastal shipyard in Southeast Asia required a flexible solution to handle a newly built 6,500 DWT multipurpose cargo vessel. The site faced space constraints and uneven ground conditions, making traditional rail-based systems impractical.

Hongruntong Marine supplied a customized Rubber Airbag system designed to match the vessel's displacement and hull geometry. During the operation, multiple airbags were arranged under the hull with carefully calculated spacing and pressure control.

The vessel movement was completed smoothly within a single operational window. Compared with the client's previous handling method, overall labor requirements were reduced by approximately 30%, and preparation time was shortened significantly. The airbags were reused in subsequent projects with minimal performance degradation.

* Other sizes can be produced following client's requirements.

• High Load Bearing Performance: Designed to withstand substantial compressive forces while maintaining stable structural integrity. The reinforced cord layers are arranged in optimized angles, enabling the airbag to carry heavy loads without excessive deformation.
• Exceptional Wear and Fatigue Resistance: The outer rubber layer is formulated with high-abrasion compounds that resist surface damage caused by friction, rough ground, and repeated rolling.
• Flexible Pressure Control and Elastic Response: By adjusting internal air pressure, operators can fine-tune the bearing force to match specific load conditions. The elastic nature absorbs shock and vibration, reducing sudden impact forces.
• Adaptability to Harsh Environments: Resistant to UV exposure, saltwater corrosion, and temperature fluctuations, making it suitable for long-term use in coastal, tropical, and offshore environments.

• Vessel Handling and Positioning: Widely used for controlled movement and positioning of vessels within shipyards. Its rolling capability allows precise adjustment even in limited spaces.
• Maintenance and Dock Operations: Provides temporary support and controlled elevation during maintenance or docking preparation. Its soft contact surface minimizes hull damage.
• Offshore and Heavy Structure Support: Serves as a reliable support medium for large prefabricated structures in offshore construction and industrial projects.

• Proven Engineering Experience: Years of experience in marine pneumatic solutions with deep understanding of load mechanics, material behavior, and operational safety requirements.
• Customized Design Capability: Tailored solutions including diameter, length, reinforcement layers, and pressure ratings to ensure optimal performance for specific project conditions.
• Strict Quality Control System: Each production stage follows strict quality standards with load testing and pressure validation for consistent and reliable performance.
• Professional Technical Support: Pre-project consultation, operational guidance, and after-sales support to reduce risk and improve efficiency.
