    Nice, I really think that third anchored line for the haulee is very nice to have, when possible.

    One man hauling, rope pulley-ed through a carabiner, other side fixed --- I am calling that a 1-1/2 man haul. The person actually doing the hauling has a 2:1 advantage.

    Except it wasn't one man hauling, there were 2 of us hauling from the top and the guy coming out of the pothole had a 3rd fixed line that he was using to help.

    Didn't see much hauling from the second person. That side did not seem to move much. Therefore It looks like functionally a fixed line.

    If you are going to do a two-man haul, tie a knot in the bight, and have the victim clip in to that. Result: force applies is equal to the sum of the two people hauling. With a pully at the waist, the force applied is twice the weakest person pulling, and in the event of a slip or one person not pulling very well, traction is not lost.

    In this scenario, the first person was in a good position to pull strongly and did. The second person was in a weak position to pull, and did not do very much.

    Of course, maybe the geometry was not as it looks in the film. The Magic of Hollywood!!!

    I think it was a little of both, I was the second man and not in a great position so I wasn't hauling as much, but I was doing more than you can see in the video. I'll have to remember to tie a knot next time, I wasn't the first one up and I just took over to relieve someone and send them forward.

    My favorite kind of potholes escapes- where you get a ride prior to being plucked out by strong dudes.

    I avoid tying a knot in the bite because it creates a contact point between rope and rock. Dragging a loaded knot up the wall of a pothole can kill a rope in a single haul. Something to be aware of.

    We haul like this frequently and have never dropped anyone. :)

    Past performance is no guarantee of future results...

    More important on the higher ones. And with feeble old men hauling.

    I just discovered this thread and am excited to study up on these techniques because I KNOW this is an area where I need help. :help: Thanks, Ram!

    Not sure I understand the physics behind this. Are you suggesting if one person is hauling at 100 lbs and the other at 50 lbs, you get 150 lbs of force with a knot and only 100 lbs without a knot. Is that really true? I'm going to have to think about that for a while.

    The strand of rope going to puller A and the strand of rope going to puller B are connected by a pulley - so the tension in rope A is the same as the tension in rope B.

    In essence, the stronger puller cannot pull with more force than the weaker puller - but CAN pull faster at that weaker force. If Puller A pulls with 100 lbs but does not move the rope, then Puller B will pull with 101 lbs and pull rope through the pulley, lifting the Ram... er, the load at a moderate pace.

    My girlfriends and I are heading out this weekend with the purpose of practicing "captures" and spotting techniques, so I am stalking this thread and loving it. Although I our group is made up of 4 short girls, so some of these ideas might not work for us. But that's where the fun and creativity comes in! :)
