Actual Mechanical Advantage – Rope Rescue Rigging Systems

/ Blog, Mainline Systems and Operations, Mechanical Advantage

The T-method of analysis allows us to account for the friction in the pulleys and calculate a more accurate mechanical advantage. The efficiency of each pulley is calculated by measuring the difference between its theoretical output force, from our original system analysis, and its actual output force, determined experimentally. The efficiencies are then multiplied together […]

The New Harken Industrial Wingman

/ Blog, CMC Rescue, Harken Industrial, Mechanical Advantage, Pulley Systems, Pulleys & Mechanical Advantage

The Harkin Wingman is a compact haul kit that offers versatility, functioning as either a four-to-one or a five-to-one kit depending on how you position the load. You’ll notice significant distinctions when comparing the Wingman to other mini haul kits available on the market, with one notable feature being its exceptional compactness. We’ve engineered this

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

Progressing to the Next Level in Understanding Mechanical Advantage Using The T-Method

/ Blog, Mechanical Advantage, Pulley Systems, Pulleys & Mechanical Advantage / 295 Comments

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

Functionality of Mechanical Advantage and Considerations

/ Blog, Mechanical Advantage, Pulleys & Mechanical Advantage / 139 Comments

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
