The release of our NEW Mainline Systems eBook!

Written By: Lance Piatt

Friction… It’s gravity’s most powerful accomplice. But do you know how to leverage it to your advantage? There is nothing more important than people’s lives hooked onto the rescue line, Technicians included!

Rope rescue requires rigging skills to either move or hold things in place. As simple as this sounds, a complete working knowledge of pulley systems and mechanical advantage is a must.

Mainline systems are the workforce contingent for all rescue and rigging operations. There’s a lot going on and much to keep track off! It’s vital that you know how to construct a Mainline system that can easily and safely convert from a lowering to a raising system.

As you well know, a mainline is not always a “simple 3:1” raise change to lower, or the other way around. Mainline systems can be a 360° option at times.

Raise and lower a mainline system with confidence, knowing that you’re operating…
  • Safely
  • Effectively
  • Efficiently
  • And in control of the rescue package
Maintaining controls of all the many aspects of friction during a rope rescue operation is a must. 

When choosing an anchor for a lowering system, we must build it strong enough to withstand the forces generated by the raising system that we will be going to later. With the use of a high directional, the unwanted friction is all but eliminated.

Maintain proficient knowledge of the key mainline operations! Overcome the most commonly occurring problems when switching from lowering to raising with a mainline system by pre-planning the layout of the working/haul line system.

Inside this eBook, we’ll cover topics such as:
  • Pre-plan the Working Line
  • Choosing an anchor system
  • Equipment for Lowering Systems
  • Simple Pulley Systems
  • Pulley Systems for Hauling, Lowering, and Holding
  • Mechanical Advantage with Pulley Systems
  • Critical Thinking on Mechanical Advantages
  • Practical Mechanical Advantages (PMA)

Maintain an ideal range of mechanical advantage, weight control, and friction, build a clean, effective and efficient Mechanical Advantage mainline system, and bolster your knowledge of Mainline Systems with this must-have eBook. FREE for a limited time!

Peace on your days…
