Description
Our Ship Launching Balloons are engineered for versatility, supporting ship launching, salvage operations, and heavy lifting. With sizes ranging from 1m to 5m, they accommodate various vessel weights and types. The multi-layered rubber construction ensures puncture resistance, while the oil- and chemical-proof design enhances durability in harsh marine environments. Quick inflation/deflation saves time, and their compact storage makes them a practical choice for shipbuilders and rescue teams. A reliable, reusable alternative to steel rollers and slipways.
