Instead of using the branch as a pulley, lift the bag into position with one hand while pulling the slack out of the rope with the other. If the bag is too heavy to lift over your head with one hand, have a second person pull the rope while you lift the bag with both hands. This will greatly reduce the friction on the tree limb.

Using anatolyg's idea of the carabiner, I think this will work. Thank you Anatolyg!

P.S.: I just noticed the question explicitly said indoors! My answer ended up being considerably more general than required... But well, the logic is the same as in case (a): Indoors the bolts are really close, so you should climb (or downclimb) to the nearest one and attach yourself to the fixed quickdraw using the harness belay loop. Both options you ...

Make a figure-8-on-a-bight knot on the center of your rope; clip a carabiner into the knot. Clip the center of a second rope into the carabiner. Toss your first rope over the tree branch using the original method. Use the second rope to raise the bag, using the carabiner as a pulley. To reduce friction, you can add a real pulley to the carabiner if you have ...

The Yosemite bowline is just a simple bowline with a Yosemite finish. This finish can also be used with other knots, such as the figure 8. It is fail-proof for the figure 8 case, meaning that if you make it wrong the knot will compensate your mistake by tightening the rope on the correct spots. It is not fail-proof when used together with the bowline, as can ...

To connect two poles (of roughly equivalent size) in a square angle you should be using the square lashing, as you already suggested. Here is a good animated tutorial showing how to tie it: https://www.animatedknots.com/square-lashing-knot Note the steps no. 13-16 from the above tutorial, where you basically "circle" your lashing between the two poles on ...

Arborists have this problem. The solution is a "friction saver" or "cambium saver". It consists of two rings, one large and one small, at the end of a length of webbing or rope. Here are some examples from wesspur.com For light duty you could easily make a similar device yourself with two differently sized rings and a piece of rope. ...

Even though I am late on this, I'd like to try to give you some answers on your questions. I am volunteering in the german mountain rescue service, but I am in no way an expert in climbing security - so please take everything below with a grain of salt. 1.1 We use redundancies for virtually every type of rescue but there is usually a lot more weight ...

This is called a cows tail tie in, it's a standard guide technique, and is merely a retraced overhand on a bight.

A variation on others' answers (which I have not tried, but speculate should work) - if you don't have a carabiner or arborist's tools or whatever, you could make do with just the rope itself. Tie the end of the rope around the tree limb - use a square knot or other non-slipping knot to leave slack in the resulting loop. Pull the long end through the loop, ...

You are looking for the barrel knot: https://www.youtube.com/watch?v=yRfjF5TcQbw. This is used by climbers to make sure the rope can't pass through the hole in a belay device.

I'd suggest a "slippery figure of eight" - although i'm not sure if that's the right canonical name for it. It's my go to knot I use when trying to shorten guy lines on a tent or tarp - i.e. when I have a runner with a hole and can pull some of the line through, tie a stopper knot and then use the shortened guy line. When taking the tent down, a ...

From the samples you give I assume you are a climber or use the knots in a related field. Keep to the names accepted in the climber community, as that is how the knots (bends or whatever) are known. The only working way to tell one knot apart from the others is to include a good picture of the knot, although in some cases a video may also work. Knot names ...

I do see a need for a munter hitch. I make an anchor at the bottom like usual. I usually make also an anchor prusik at first bolt, because I think knots as the weakest point of the system, or place it otherwise you will keep rope longer if not fall on knots. Then I tight a prusik on my harness, and climb giving slack through moving the prusik with one hand. ...

Your first concern is OK: tightened prussik loops do not cut ropes even after hard falls [1]. There are, however, several other problems with your set up. The munter hitch is not dynamic enough to allow the rope to run - even without the prussik loop. The prussik loop will definitely get tightened during ascent. The loop of rope that will form between the ...
