In a rescue rope system, which device is used to prevent the litter from moving backward between haul cycles?

• A. Girt hitch device
• B. Haul-back device
• C. Progress-capture device
• D. Litter anchor device

Answer: (C)

In a rescue rope system, controlling the load’s position between haul cycles relies on a device that captures progress and prevents backsliding. The progress-capture device is designed to hold the litter in place after you finish a haul increment, so the load doesn’t slip backward when you pause or reset for the next pull. It releases or allows the next forward movement when you initiate the next haul, giving you a controlled, stepwise advance.

The other devices have different roles. A girt hitch device is used to secure the litter to an anchor or rope hitch, not to lock movement between cycles. A haul-back device helps with returning the line or repositioning it, rather than preventing backward movement of the load. A litter anchor device simply secures the litter to a point and doesn’t actively lock in place against backsliding during cycle transitions.

So, the device that best fits the function of stopping the litter from moving backward between haul cycles is the progress-capture device.
