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.RPM Definition Rack Pulley/Prusik Mariner’s Knot (a load release strap) with pulley and prusik attached as shown Rope Rescue System Components Anchor Anchor Double Prusik Belay with Mariner’s RPM Mainline Belay Line Both Mainline & Belay Lines always have separate and dedicated anchors 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.
