Two Rope Tension System A-Frame Resultant Insight, Part 2

Excerpt from “A Guide to Artificial High Directionals & Two Tension Rope Systems” To review, this simplest way to make sure it’s stable is to visualize your resultants and make sure they’re landing within the footprint of your system. Then provide some guying for stability and the insurance that in the event that someone should […]

Pulley system efficiency tests with Petzl Maestro, I’d S, Pro Traxion and RollClip

There can be a big difference between the theoretical efficiency of a pulley system and its actual efficiency. Here are test results from the Petzl lab. 1. Efficiency depending on the device used at the head of the system. The force required to raise a 100 kg mass was tested under several configurations with different
