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.
Rubber Airbags are available in a wide range of diameters and lengths. Custom sizes can be manufactured according to load requirements and operational conditions.
With proper operation and maintenance, Rubber Airbags can be reused multiple times. Service life depends on load conditions, surface environment, and handling practices.
Only standard air compressors and pressure monitoring tools are required. No complex mechanical systems are needed, reducing operational complexity.
Each Rubber Airbag is designed with a defined safety factor and tested for pressure stability. Proper spacing, pressure control, and operational procedures further enhance safety.
Yes. The material formulation provides strong resistance to seawater, UV exposure, and temperature variation, making it suitable for extended marine use.
