Imagine... you find yourself in a spot where you were unable to ride your motorcycle to solid ground. I found myself in just such a situation, and it gave me the perfect opportunity to deploy and demonstrate a "z-drag" pulley system. It's a 3:1 mechanical advantage pulley system comprised of two mechanical prusiks, a mini pulley, three carabiners, and a length of static line and 1" webbing.
Your knowledge, skill, and physical fitness will all come into play using this system. It will only ASSIST you...it's not an electric winch. Having friends helps tremendously; as operating this system solo WILL test your fitness.
There are options for the individual components of this system, and buying a complete system that is ready to deploy right out of the box does exist. I choose to hand-pick the components based on my desire to have the ability to separate and use the components for other uses not discussed in this video; as well as size, price, and most importantly... load rating. ADV bikes are heavy and depending on terrain, can demand that your gear lift the bike at near-vertical angles.
Petzl, Kong, etc all make excellent rescue/mountaineering equipment... but based on the factors above as well as progress capture efficiency, I choose CT Climbing for the most important piece of this system. (Based on time of purchase - 2020)
Below is a list of the components I have, and how many are required:
CT Climbing - RollnLock x2
GM Climbing - Mini Pulley x1
Carabiner x3
10mm STATIC Line 50ft (DO NOT USE DYNAMIC/CLIMBING ROPE [See Below])
1" Webbing ~10ft x2
WARNING: Dynamic/Climbing rope/cord is elastic and designed to stretch when a load (climber) is falling in order to absorb the shock and protect the climber. Using dynamic rope in the system will stretch and create an unsafe load (spring) in the system. USE ONLY STATIC LINE.
