What is the primary purpose of edge rollers in rope rescue?

The primary purpose of edge rollers in rope rescue is to reduce rope friction and wear. When a rope is running over an edge, it can experience significant friction, leading to wear and potential damage to the rope. Edge rollers are designed to maintain the smoothness of the rope's path, allowing it to glide over the edge without excessive friction. This not only protects the integrity of the rope but also ensures a more efficient operation during a rescue scenario. By minimizing wear, edge rollers contribute to the safety and effectiveness of the rescue operation, making them an essential tool in a technical rescuer's kit.
