PULLEYS AND MECHANICAL ADVANTAGE SYSTEMS

By Lance Piatt / Blog, CMC Rescue, Pulley Systems, Pulleys & Mechanical Advantage / 375 Comments

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 of Mechanical Advantage Systems

By Lance Piatt / Blog, Pulley Systems, Pulleys & Mechanical Advantage / 259 Comments

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 …
