From Stephen Attaway for ITRS: Track Lines and Guiding Lines: Forces Based on Point Loads in a Catenary

In Track Lines and Guiding Lines: Forces Based on Point Loads in a Catenary, Stephen Attaway says, “The scope of this paper is limited to providing a better understanding of how to predict sag, tension, forces, and possible hazards.” This research was originally presented at the International Technical Rescue Symposium (ITRS) in November of 2013, …

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 …

A Quick Look at Two Tension Rope System and a Dynamic Directional Offset using Two Artificial High Directionals

The Purpose (Vision) We have always encouraged experimentation and creativity when learning.  I do my best to take the advice of people I respect.  The other day I sat in the studio thinking about some unused space we have and decided to build a test piece… a small slot canyon where a hiker needed to …

Carabiner Shaming: Losing The Gold

I’ll admit it.  I’m guilty. I’ve done it.  Nope, I’m not talking about stepping on the rope, using dropped carabiners, or mistakenly peeing on my belay loop… c’mon winter layers can be a challenge!  Nope, I’m talking about what I’ll call “carabiner shaming.” Like many, I used to pick apart photos on the interwebs to …

Mechanical Advantage: 2:1 or 3:1? – RLA Partner Richard Delaney of RopeLab

I thought this was a super quick illustration to show how observation and proximity make a difference.  The question, here is  what is the mechanical advantage difference between a “ground hauler” or that of the “load hauler”.  The significance is found in the frame of reference… the applied force to the input is what defines …
