What is a Z-drag and what advantage does it provide in rope rescue?

• A. A Z-drag is a hauling setup using multiple pulleys to create mechanical advantage; it reduces the effort required to move a load.
• B. A Z-drag is a knot used for anchors.
• C. A Z-drag is a method to cut rope.
• D. A Z-drag uses a single pulley to maximize effort.

Answer: (A)

In rope rescue, a Z-drag is a hauling setup that uses multiple pulleys arranged to create mechanical advantage, so you can move a load with less applied force. By routing the haul rope through two fixed points (pulleys or anchors) in a zigzag “Z” pattern, the load is supported by several rope segments. That shared load multiplies the effort you put in, allowing you to move heavier loads more easily and with smoother control. The typical advantage is around 3:1 or 4:1 depending on the exact routing, which is why this method is preferred over a straight pull for longer hauls or heavier loads. This is not a knot for anchors, not a technique to cut rope, and it relies on more than a single pulley to achieve the mechanical advantage.
