Harken’s new WingMan applies new design and technology to achieve more from a compact personal mechanical advantage system. WingMan’s innovative design makes it among the first offerings in this category to achieve internal progress capture mechanically within the unit rather than relying on prusiks to achieve that externally. WingMan combines a ratcheting sheave to stop …
Excerpt Taken From Rigging Lab Academy’s ~ Confined Space Rescue: Technician course Confined Space Rescue Split 4:1 Introduction With the introduction of Petzl Grillons, AZTEKs, and other small mechanical advantage devices, a lot of people don’t use a rig split 4:1 anymore. If you don’t have access to a Grillon or small mechanical advantage systems …
Welcome to the third and final demonstration installment of our confined space rescue series… Confined Space Rescue Demonstration: Technician. We have a stacked line for you with tons of tips, information, and demonstrations. What you’ll be watching is far from exhaustive, however, we’ve tipped the scales way beyond anything you’ll find on the open market. …

Get More Done With Less… and remove the mystery out of “the theory” of Mechanical Advantage Systems. Mechanical Advantage Systems ~ arguably is the “bulwark” of rope rescue… giving strong support, encouragement and leadership to those in need. Wait! Doesn’t “bulwark” have to do with wall like structures raised for defense? Like a seawall? Sort …

When we developed ideas into courses, we considered many things. Yes, we went through the SWOT analysis as well. Know this will get you What, Where, When, and How! Strengths Opportunities Weaknesses Threats I will let you reference this, however we went through all 4 elements before we engineered, designed, went to production and released …
Kudos goes out to Peak Rescue Institute for the help. The purpose of this lesson is to give the student rescuer a more thorough understanding of mechanical advantage. It will review basic concepts learned in the technician course and add advanced concepts such as the T-method, system efficiency, haul system progressions, and counter-balance haul systems. …

Thank you to Peak Rescue Institute for the graphics In this section, students will learn five different MA systems: 1:1, 2:1, 3:1, 4:1, and 5:1. This range of MA systems is sufficient to address the majority of rescue hauls encountered in normal field operations. As with most other aspects of rope rescue, consistent practice building …
The Mechanical Advantage (MA) systems used in rescue incorporate one of the most elegant simple machines known to man, the pulley. While it is Newtonian Physics that explains how pulleys work, we owe the Sicilian mathematician Archimedes for its invention. History tells us that Archimedes boasted to his king that with enough pulleys he could …

Thank you Peak Rescue Institute Full Video at the bottom So progressing up through the levels of mechanical advantage from 3:1, we can go to a 4:1. For those in the fire service, this is a fairly common mechanical advantage system that we’ll find actually piggybacked onto a main rescue rope. So we’ll build a …
Thanks to Peak Rescue Institute Full Video at the bottom! In general, the Ideal Mechanical Advantage (IMA) is the ratio between the distance the load moves and distances the haul team moves. In a 2:1 system the load will move 1′ to every 2′ of haul. However, this does not mean that lifting the load is twice …
