Rope Rescue Pulley Systems Diagrams

The obvious challenge of importance to the rescue attempt is the need to get the victim down.

Rope rescue pulley systems diagrams.

In a simple system one rope is routed between pulleys on the anchor and load and all of the pulleys that move i e the traveling pulleys do so at the same speed and in the same direction as the load. Any ultimate benefit from the rescue maneuver hinges upon pulleys systems for rescue industrial rope. Simple m a systems can be defined as systems with all the moving pulleys moving at the same speed as the load. 3 1 system the 3 1 is the classic mechanical advantage system used by rescuers.

A few simple pulley systems are most frequently used. Mechanical advantage systems can be either simple compound or complex. 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. Pulley systems introduction victims in the field of rescue often times find themselves stranded somewhere well above head level on cliffs mountains bridges buildings and other structures.

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.
