TIP forces of DRT

[DBJR]

Recently began using a DMM rig pulley on a loopie for a tie in point. Saw in some tech. documents for hitchclimber that you can attach another pulley to the becket and pull your tail through and get some mechanical advantage. Tried and I can pull myself up with one hand! Just wanted to check if that somehow multiples the force on TIP. I'm not attached to the ground in anyway so I assume it doesn't but there's a problem with assuming!

Doesn't sound like to me that you are multiplying the load on your tip. A pic would help.

The force on the tree is the same. It's your weight hanging off it wether it's on one leg of line or 4 if it's all rigged like you say. Where you can get into some force multiplication of a tie in point is on a basal anchor in an srt setup. Thats a whole other can of worms

Yep...you can have 97 pulleys in your line, but it is still just your weight hanging off of a single point.

You joke but after watching a modern climber on Youtube, 97 isn't too far off.
