Description
Marine Rubber Airbags revolutionize ship launching and recovery with their high buoyancy and flexibility. Designed in sizes from 1.5m to 5m, they support vessels weighing 10–200+ tons, distributing weight evenly for a smooth launch. Made from reinforced rubber and nylon layers, they resist abrasions, oil, and UV damage. Unlike traditional methods, these airbags reduce infrastructure costs, require minimal manpower, and allow for precise control during operations. Their quick-deployment feature speeds up workflows, making them essential for shipbuilders, naval bases, and repair docks.
