@hftfire mechanical advantage.

See the you tube video of the frictionless descender. Search for j-arms. This rappelling device will revolutionize the sport and rescue applications. There is always an easier solution.

It doesn't look like there is any MA unless you consider the leverage of the length of the handle that you are cranking. I wonder if you can effectively build this into a z-rig. Seems a little sketchy though. I like good old fashioned man powerdoing the hoisting.

The mechanical advantage. If a person apllies one pound of force to the winch, how much force is generated by the winch.

The world's FIRST ever single operator Hand Rope Rescue Winch that utilizes the mechanical advantages of the Prusik and a fixed anchor that can be established in a matter of moments. SAFETY FIRST!
