He set his progress capture prusik on the worst line. You see how all the lines go slack when he sets the brake except one, that means he has all the weight of the load on the prusik, at a 1 to 1 ratio. If he set it at the other end of the system, it would have only had to hold 1/4 of the load at a 4 to 1 ratio. Also, when he released the haul line, he looses about 4 inches of progress when he sets the brake. If he puts the brake at the other end of the system, he will only loose about an inch of progress.

My grandfather was a house mover and rigger, he moved houses with real horse power, I have pictures those were some big horses they made the Clydesdales look like ponies, it was at the beginning of the 1900's, there were all kind of pullies and tools in his basement and garage, sadly he went blind in the sixties from glaucoma.

Would have been helpful to bring the camera closer; it’s really hard to see what is being described.

Fantastic

[@timehonored]

Yes!

[@joemanflyer2001]

You don’t say anything about the load. What are the Pullies rated at lbs? What kind of rope are you using and how long and thickness. What is the rope rated at lbs? You should shoot the camera closer so we can see how it is looped and how to ad the carabine? Thx. Joe.

I'm trying to look up "friction hitch" but can't find anything that looks like that
