In the high-stakes arena of rescue operations, the role of a technician or director parallels that of an astute business leader, where efficiency and team synergy are paramount. Just as a well-designed pulley system in rope rescue allows for maximum efficiency with minimal force, applying these principles of mechanical advantage can revolutionize the way rescue …
Welcome to a new era in rope access and rescue operations, where innovation meets simplicity. In the world of technical rope work, the challenges of complexity, safety concerns, and limited versatility have met their match. Introducing CAPTO and CLUTCH – a dynamic duo designed to transform the way technicians approach their work. The following is …

Rigging plays a pivotal role in the world of rescue operations, where the ability to analyze and manage forces effectively can make the difference between a successful mission and a potential disaster. In this blog, we will delve into three fundamental aspects of rigging: understanding the forces at play, harnessing mechanical advantage with pulley systems, …

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 …

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 …

This is a repost from CMCPro.com 5/17/22 Where To Get CMC Pulleys Raising systems are essential in any rescue or rigging scenario in which loads are lifted using rope. A raising system using a combination of pulleys to leverage the force applied in lifting is referred to as a mechanical advantage (M/A) system. Whether building …
System Efficiency Effect of pulley friction. Most rescue pulleys have an efficiency rating of .75 to .90 (only 75% to 90% of tension is transferred from one side of the pulley to another due to friction). A carabiner used as a pulley has an efficiency of only about 50% or less (more for a steel …

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 …
