What devices help control ropes during re-roping?

When dealing with re-roping tasks, holdbacks and separators play a critical role in managing the tension and positioning of ropes. Holdbacks are utilized to maintain a certain position of the rope or to prevent it from moving unexpectedly, ensuring that it remains secure during the re-roping process. This control is particularly important for safety and to ensure the operational efficiency of the system.

Separators, on the other hand, help keep ropes or cables apart, reducing the risk of tangling or interference between them. This separation is crucial for keeping the ropes aligned correctly and ensuring smooth operation, especially in systems where multiple ropes are in use simultaneously.

These devices together provide the necessary control to facilitate a safe and efficient re-roping process, minimizing the risk of accidents or equipment failure. The other options, while they may relate to various mechanical processes, do not specifically address the control mechanisms needed for managing ropes during re-roping tasks.
