SEE FOR YOURSELF
When building Mechanical Advantage (MA) in your haul system, begin by adding the system components as close as practical to each other. This way you can SEE IT to make sure that the system is clean, rigged properly and lines aren’t crossed. Once the MA has been added to the haul line, then expand the system out to reach the maximum distance to the edge or load by loosening the Prusik and sliding the pulley down the line using the carabineer as a handle. Just remember, START SMALL.
