What is the best way to advance your line when climbing SRT? When I first set the line I can use the throw line to help get the rope through the 'biner if the branch is more than 1/2 the distance of my rope (e.g. setting up on a branch 60' up when my line is only 100'.

But that's not possible when one end of my line is attached to the first branch.

So can someone describe to me the technique they use to set the second (third etc) branch? Right now I'm really limited to the trees I can climb because I only have 40' of rope.

Thanks

Get another rope!

Or pull the end up after you and throw that over a branch. Make sure you throw a collapsable monkeys fist rather than a carabiner, if it gets stuck you can be in trouble.
If you are making a nooseloop to cinch to branch for SRT, you can also anchor it to yourself and make a DdRT loop. More damage to tree and rope but a basic technique.


moral of the story:

You need at least two tie in points to move in a tree. try both ends of the same rope.

Thanks.

That's actually what I do now. I can only throw the other end of the line to a branch less that 15' above the one I'm on (about 8 feet tying me onto the first branch, leaving 32', half of that is about 15). I can then use DRT or put the loop onto the line and pull it up for another SRT.

My question is - is there a way to get the SRT line around a branch say 25 feet above the first one? I'm a bit too broke to get a new line yet - when I do I'll probably get a much longer one.

Any ideas of what I can do in the meantime?

Tying in with a lanyard would allow you to use the same technique you used on the ground to progress further up the tree.

You're right. That's my problem exactly. If I use DRT I'll have no rope at all to advance with. My plan is to use SRT the whole way.

I think what Blake said is probably the only option I have. At each branch I'll have to switch to a lanyard, then advance the rope. It'll take some time, but hey, at least I'm spending it in a tree.

Of course, if you are lucky youve got a beloved "groundie" ready to undo the anchor once you are up there!!

Anchor? Not sure what you mean.

oh sorry, i lost the plot. your initial post implies you are anchoring the rope on itself. you could alternately anchor it to the ground, which would be the way to go if you had branches in the middle.

One small warning: if you anchor one end of your line at ground level and climb SRT on the other end, the laws of physics show that you double the amount of weight on the limb.

It works like this -- if you weigh 100 pounds and climb DRT from a limb, you are putting 100 pounds of weight on the limb. If you weigh 100 pounds and climb SRT with the rope cinched up tight against the limb with either a running bowline (not recommended by some climbing professionals) or with spare carabiners or a delta link, you are still putting 100 pounds of weight on the limb.

But, if you run the rope over the limb and back to an anchor point on the ground and then climb on the other end of the rope, you are putting 200 pounds of weight (100 from the climbing side and 100 from the anchor side) on the limb.

Personally, I use that method only on my initial entry into the tree and only if the limb supporting the rope is very big (in fact, I prefer to have the rope running through the main crotch if possible).

Remember, gravity always wins!

The weight on the limb in SRT or DdRT doesn't change but the load does. Small difference :)

WB,

Do you have a problem with working/climbing on SRT with the rope anchored at the ground because of the doubling of the load?

Strong limbs and single ropes!

Terribly sorry, old chap --

I stand corrected; instead of doubling the weight on the limb from 100 pounds to 200 pounds, I have simply added another 100-pound load to the system...! Picky, picky, picky.

Okay, that's enough fun with you, Tom. In a few minutes I'm headed down to my practice tree to try out some new stuff that came to me in the middle of the night. I'd tell everybody what it is, but it might turn out to be so stupid that I'd rather nobody knew about it until I can prove it either useful or worthless. If it turns out to be useful I likely will brag about it at a later date; if worthless, there will be no additional posts regarding the subject...!

1 Buy another rope
2 Tie your self to the tree using a sling or something take of the rope then do whatever you do to get it on the next branch
3 pull your remaining rope and use that to throw to a higher branch

Hoped it helped
