3×18m Ship Launch Airbag Supports High Tonnage Optional Layers After Sales Support
Description
Crafted from eco-friendly natural rubber and layered with durable tire-cord fabric, our ship launching airbags are both strong and flexible. They are resistant to seawater corrosion and mechanical damage. These airbags are available in a variety of sizes including 1.0×8m, 1.8×15m, and 2.5×18m, with additional custom options. With excellent elasticity and shock absorption, they are ideal for launching fishing boats, cargo vessels, and barges. Easy to deploy and recover, they reduce labor intensity and improve safety compared to traditional slipway methods.
