Thank you Peak Rescue Institute Let’s begin with manual hauls. When you talk about manual hauls or mechanical advantage, you have to talk about work. Work is done when force moves an object. Well, what’s this thing called force? Force is simply a push or pull that causes an action. And in fact, force can …
A mechanical advantage haul system reduces the effort required to raise a load. The mechanical advantage obtained is based on the pulley effect. 1. The pulley effect If we consider a load suspended on a rope, the rope passing through a pulley above the user, with the user’s hand holding the rope on …

Basic Highline System with Pulleys, Rope and Pulley Systems for High Angle Technical Rescue Highline operations are one of the most dangerous and most difficult vertical rescues. Highline rescues invoke the use of advanced rigging skills, performed by advanced technicians. Under no circumstances should a highline be attempted solely on the instruction of this …
Mechanical Advantage Overview Mechanical Advantage is a measure of the force multiplication achieved by using a tool. In most cases, this involves using pulleys, but that isn’t always the case. The purpose is to show how we can achieve more work with less people AND that sometimes having more people can actually be dangerous. An …
Marginal anchors in theory create a force out of many, but how should we present this diverse and sometimes controversial concept of anchor construction? This is an introduction to multiple back-ties and projecting the power of substantial anchors to a single focal point. Marginal anchors are generally considered independent anchors points that would not support …

Excerpt from Knots & Pulleys in Rope Rigging Systems Vol. 1 Segment 7 Let’s continue with our discussion on pulley systems. We can look at what we have right here. You can see the Vortex and we have a sandbag as a weight right now. What we have here in the way of a …

Over the last year or so I have been trying to up my rigging game with the main focus being “rigging light, rigging quick, rigging solid and rigging efficient”. I will be the first to admit that all for all of this to happen at the same time it is a special day. I will …
Today at Rigging Lab Academy, we’re going to bust this myth that parallel mechanical advantage systems somehow add together and double mechanical advantage. There are arguments out there that two 3:1s side by side pulled on the same load are a 6:1, or two 5:1s are a 10:1. It’s not true, and we’re going to …

So in this installment of Litter Hauling Techniques Using Dual Capacity or Twin Tension Rope Systems Part 2, I would like to jump into anchor and anchor systems used in a few of the systems we set up here this week. Neverland has three upper platforms or stages (as we call them) and the lower Ground …

What to learning something well?… “Do it yourself “. Well, this isn’t always the case, but for me (right now) it is. While not obsessed, I am really curious as to what a true minimally viable raise and lower system looks and feels like. Remember the 3 types of learning?….. Vision, Auditory and Kinesthetic. Well, …
