What is the maximum practical distance for a highline operation?

In highline operations, the maximum practical distance is considered to be around 100 meters due to several factors affecting the safety and efficacy of the rescue technique. At this distance, the system can still allow for effective communication, control, and stability of the loads being moved or transported across the line.

Longer spans can lead to increased dynamic forces on the system, making it harder to manage tension and stability. Beyond 100 meters, the potential for swing and collapse increases, which can compromise both the safety of the rescue personnel and the individuals being rescued. As the distance increases, the complexities of rigging, the management of slack, and the potential for more significant environmental factors (like wind or terrain) add further challenges to a successful operation.

This distance is often determined based on a combination of best practices from prior operations and established safety standards within the rescue community, aiming to maintain a balance between efficiency and safety.
