5 Rules to Help Determine Simple & Compound Mechanical Advantage Systems

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 …

T Method Applied To Mechanical Advantage Systems Using Rope Grabs

T Method Applied To Mechanical Advantage Systems Using Rope Grabs. Calculating mechanical advantage: the T-system 1. Assume continuous strands of rope have the same amount of tension. If we start at the point where effort is applied and assume that we apply one unit of tension (1T) then we can assume that the tension along …

Marginal Anchors | Anchor Considerations in Rope Rigging Systems Vol. 2

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 …

Staggered Anchors: Progression from 3:1 to 9:1 Simple Mechanical Advantage

  Excerpt from Knots & Pulleys in Rope Rigging Systems Vol. 1 Segment 7 In continuing with the discussion about pulley systems this video reviews the 5 rules of simple pulley systems before delving into the principles of a 3:1 MA, mechanical advantage, and compounding a 3:1 system to a 9:1 using staggered anchors for …

The Gear Used In Artificial Highlines and Two Tension Rope Systems

Ultimate – the best achievable or imaginable of its kind. Can we have The Ultimate Gear List for anything?  Probably not, but we can put some thought into what that might look like. Before we get to the list, let us outline where this gear cache came from. In building this course with Jason Ilowite …

How To Calculate Mechanical Advantage

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 the …

A Little Known Tool That Is Making Huge Headway… The Inside 9 Mechanical Advantage System

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 …

Parallel Hauls, Doubled Mechanical Advantage or Not?

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 …

For Two Tension Dual Capacity Rope Systems Savvy Technicians: The Efficiency Schematic

So lately, I have been going through a type of transformation of sorts.  I will be honest… not all of the process has been fun and pushing through bias demons can be difficult, but with friends like Craig McClure, Jason Ilowite and Rich Delaney… the sojourn has been rewarding.  Bear in mind that a sojourn …
