The speed differential fall arrester ensures the personal safety of welding workers in large cabin structures

The total length of the cabins of large ships, rockets, and the Shenzhou-16 manned spacecraft is over ten meters, and the height is also over five meters, which is very tall. These cabins are not naturally so large, but are pieced together like a puzzle by welders.

The welding master holds a welding gun and performs welding operations on a certain part. The cabin has many welding parts and complex structural forms. The total length of the weld seam is 50-60 meters, and the shape is irregular, including round and square ones. The welding difficulty is very high. In order to ensure the welding quality, the "seam" quality must be observed at all times during welding. Therefore, the welders stand for several hours at a time, and their bodies are in a very tired state. During the process of walking back and forth on the high-altitude work platform, it is very easy to have accidents of falling from high altitude. Fortunately, every welder wears a speed differential anti fall device and high-altitude work safety belt.

The seemingly dazzling but actually scorching welding flowers are very easy to splash onto the ropes of the speed difference anti fall device and seat belt. However, these ropes are woven with aviation grade flame-retardant ropes, which have strong flame-retardant properties, ensuring the safety of large cabin welders while maintaining their own locking function and safety characteristics.
