In-Line RPM requires the most area in-line with the direction of travel (up & down).It IS NOT self-tending and must be tended by hand! Pig-Rig RPM (Raise) Change of direction pulley is clipped directly to anchor plate to reduce pendulum effect when hauling A Pig-Rig RPM raise incorporates an additional rope system “piggy-backed” onto the mainline with a prusik Ratchet prusik is on the end of the Mariners to extend it’s location away from the pulley. RPM is configured differently than In-Line or Change-of-Direction RPMs (see above) Pig-Rig RPM (Lower) Prusik is removed from here & set aside Pulley & carabiner are removed from here & set aside The Pig-Rig RPM adds an additional rope for raising operations, enabling the mainline to be fully extended to it’s maximum reach. RPM configuration is the same as In-Line. Pig-Rig RPM employs a second rope for mechanical advantage allowing the mainline to be fully extended over-the-side to it’s maximum length or “reach”.Ĭhange-of-Direction RPM (Lower) A change of direction pulley and anchor are added here The Change-of-Direction RPM bends the Mainline 90 degrees to keep the system off of a roadway or position it to a more advantageous location.Change-of-Direction RPM bends the mainline 90 degrees to move the system off of a roadway or to a more advantageous location.In-Line RPM is the simplest and uses the least amount of gear.There are three distinct configurations of RPMs for Rope rescue & access.

Let’s look at an illustrated example of the most basic configuration on the next slide….

There are 3 configurations of rope rescue systems generally agreed upon by Fire Service Rescue professionals in California that can be adapted to any rope rescue or access situation.

A Belay line which provides a redundant safety component for those who are suspended from the mainline.

Rope Rescue Systems incorporate a mainline to lower and raise rescuers and victims and.
