Rope rescue pulley systems diagrams.

Mechanical advantage systems can be either simple compound or complex. Simple m a systems can be defined as systems with all the moving pulleys moving at the same speed as the load. Any ultimate benefit from the rescue maneuver hinges upon pulleys systems for rescue industrial rope. 3 1 system the 3 1 is the classic mechanical advantage system used by rescuers.

The most common is a 3 1 mechanical advantage sometimes called a z rig because when rigged the rope looks like a z. The obvious challenge of importance to the rescue attempt is the need to get the victim down. They are typically used for hauling and lifting loads but can also be used to apply tension within a system such as in a tensioned line or tyrolean. A few simple pulley systems are most frequently used.

It requires less rope than a non piggybacked 2 1 system is reasonably easy to rig is easy to add a progress capture device provides an appropriate amount of mechanical advantage to raise one or two people and with a few tweaks it can be converted into a simple 5 1 system.
