What is progress capture in a hauling system?

• A. A method to minimize rope wear by guiding rope around edges.
• B. A method (often using a friction hitch or dedicated device) to prevent backslip and allow resetting tension while maintaining advantage.
• C. A technique to store rope inside a bag.
• D. A device that automatically tightens rope to maintain constant tension.

Answer: (B)

Progress capture is the technique of locking the moving rope in a hauling setup so the load can’t slip backward when you ease, reposition, or reset tension, while still preserving the system’s mechanical advantage. It’s usually done with a friction hitch (like a Prusik or Klemheist) or a dedicated progress‑capture device. The key idea is to hold the progress you’ve made in the haul so you can re-tension and continue hauling without the load sliding back down the line. This keeps control of the load and maintains efficiency of the system. It’s not about protecting rope wear, storing rope, or automatically tightening the line—the purpose is to prevent backslip and allow resetting tension while retaining the advantage.
