Thanks Peak Rescue Institute Full Video at the bottom All right. The next mechanical advantage system in our progression is a five to one mechanical advantage system. And this is a simple five to one mechanical advantage system. So we’ve already differentiated between simple and compound. The last system that we showed was a four …
Thank you Peak Rescue Institute Full Video at the bottom So progressing up through the levels of mechanical advantage from 3:1, we can go to a 4:1. For those in the fire service, this is a fairly common mechanical advantage system that we’ll find actually piggybacked onto a main rescue rope. So we’ll build a …
Thanks to Peak Rescue Institute Full Video at the bottom! In general, the Ideal Mechanical Advantage (IMA) is the ratio between the distance the load moves and distances the haul team moves. In a 2:1 system the load will move 1′ to every 2′ of haul. However, this does not mean that lifting the load is twice …
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 …

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 …

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 …
From Rigging Lab Academy Course Mechanical Advantage Theory There are three categories of mechanical advantages using pulleys: Simple, Compound, and Complex. Simple MA: A Simple MA consists of a pulley system that has a single haul connection between the load and the haul team. Compound MA: A Compound MA is a simple mechanical advantage system pulling on the haul line …
