Which device is used to change a haul system into a lowering system?

• A. Load releasing hitch
• B. Z-drag
• C. Prusik
• D. Re-direct pulley

Answer: (A)

The feature being tested is how to switch from a hauling setup to a controlled lowering setup. A load releasing hitch is designed for this exact purpose: it holds the load secure during hauling, and when you’re ready to lower, you can release the hitch to let the line slide while the brake person controls the descent. That controlled release is what converts a haul configuration into a lowering configuration, enabling you to manage the descent smoothly. The other options don’t provide that specialized release function. A Z-drag is a hauling arrangement that increases mechanical advantage; it’s not about enabling controlled lowering. A Prusik is a friction hitch used for progress capture or backup in belay/ascend scenarios, not for converting a haul to a lowering system. A re-direct pulley simply changes rope direction and doesn’t inherently enable controlled lowering.
