The "Z-Drag" creates a three-to-one mechanical advantage hauling system which multiplies the pulling force on the hauling rope by a factor of three. This is accomplished with the use of carabiners which act as pulleys and allows for a person to pull a much heavier load than with a rope tied directly to an object.

Like other mechanical advantage systems, the Z drag works by pulling the rope 3 times the distance the load is moved, to "collapse" the system. For example moving the load 5' requires pulling 15' of rope, which is 5' on each of the 3 legs of the Z. Ideally each leg is parallel so the entire system can collapse to a length of zero.
