Ship Launching Airbag: High Load Capacity, Superior Durability, Reliable Performance
Product Overview

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.

Case Study: 18,500 DWT Cargo Vessel Launch

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.
