The reason for the sudden braking of the crown speed differential device

The crown speed differential device is a safety protection device for us during high-altitude operations. When we are working normally, the rope will expand and contract freely with our movements. Once we have a high-altitude falling accident, the internal braking system can brake and quickly lock the rope, thereby preventing us from continuing to descend and causing danger.

However, sometimes when we are using the differential for normal operation, the rope of the differential suddenly locks itself, which not only affects our normal operation but also poses certain safety hazards. So why did this happen? The principle of locking the rope of the speed differential is that when we fall, the speed of the rope pulled out increases, and the brake immediately locks the rope to achieve the braking effect. Therefore, even under normal operating conditions, if we move too fast, it may cause the crown speed differential to suddenly brake; The rope getting stuck can also cause such a situation. When the rope gets stuck in the internal transmission system, the rope will be locked and we will be pulled by the differential to stop the operation.

We must be careful and cautious when using the crown speed differential, and always pay attention to the status of the differential to avoid such situations during operation.
