About the Course

An understanding of mechanical advantage systems — in raising and lower modes — is crucial to all rope rescue technicians. Dealing with Mass and Force is aspects of consequence if not considered during operations. Working with tensioned anchor systems, guying systems, high directionals, load positioning and litter movement all come into play when building mainline systems. If these are areas of concern for you — or simply areas in your rigging and rope rescue knowledge that you'd like to strengthen — this course is for you. 

What You'll Learn

Join us inside Mainline Systems where we'll dive into must-know material on:

  • Understanding the effects of gravity and friction on mainline systems

  • Mechanical Advantage Theory

  • Terms and definitions of mechanical advantage systems

  • Types of pulley systems

  • How and when to use Long Line MA Systems

  • How and when to use Block and Tackle Systems

  • Calculating tension force using the T-Method

  • And more!
