SRT questions

[Col2y]

ive been climbing for 4 years now in the toronto area, it must be a sheltered part of the world because ive never seen anyone use it.

im under the ...understanding that you set a rope much the same way as drt then you tie a running bow, or knot of choice and sinch it around your TIP, then ascend,

now not knowing everything there is to know i wonder a few things,

1 - how do you retreive your rope after you decend

2 - how do you change your tip

3 - there is so much talk about manual decenders like figure 8's that you have to control or you will drop like a stone, which seems like an accident waiting to happen

now as i mentioned before i dont know very much about SRT but it seems like DDRT is so much more efficient in the long run, sure it takes a little more to get up in the tree, but once your there you can ascend and decend with little effort when your working and you can decend to the ground just as fast and much safer,

so somebody enlighten me please

thanks

I ts hard to pick up on new teqniqes on a single thread, Ive only been here for a year. But this much i can say, if you instal your rope from the ground, and isolate your tip, you tie off one end, of your rope(at the bottom) to a tree, mecanicly advance up the other end. whence your at the top,groundie unties other end and proceed how ever dbrt. Seems to me only helpful on long acents no branches no gafts, but in that case how do you get up there? shimmy? bare foot like on a palm? Also try search and research somtimes helps if your luky. As far as a figure eight gose its helps on long decents so you can come down fast without burning up your rope, and other stuf like a belay point some times i use it to lower stuf out myself. The guys here have endless knowledge, and are inventing new things every day. It would help if some one could draw you a map.

You don't. You climb srt to your tie in point and switch to traditional climbing technique. I think this answers question 2 and 3 also.

Thiss is the system in it's most basic, were it is used solely for entry. There are advanced techniques, such as Tom D's RADS thaat can be worked on.

Another system starts the SRT line as entry, then it becomes the TIP ffor the TRAD system.

As for changing the TIP on a "plain" SRT climbi ng sysstem is just redirecting you line, either naatural crotch or sling & carrabiner.

ive been doing alot of searching on the subject, its kind of coming across as a southern hemisphere kind of thing, but i still see no advantage to it, you can still use mechanical ascenders on ddrt and its alot less pulling

On DRT you have to climb twice as far, since you are basicly on a 2:1 pulley.

One of the thoughts behind SRT is that huge trees can have a dedicated entry line for more then one climber to get set up, or where you have to work up, and downclimb to you can reenter the tree footlocking up the SRT line.

It is one more method in a broad toolbox, some older climbers with shoulder problems say it is helping them work longer.

Here is a search on SRT RADS for one year back.

1- one way to retrieve your rope is to put it in a crotch and have the groundie secure one end and the repel down the other. Ir there is no good crotch you can use a false crotch that can be rigged to choke the stem, and fall when the rope is removed.

2- I use a sit/stand rig for srt. When I get as high as I can or need to be, I simply hang on the single by the upper ascender (backed up by a prusick) while I put in my climbing line or get my lanyard around something. When I get to where I can take the weight of the srt, I unhook it and send it down.


3- Belay, belay, belay. Why this is not taught more, and used more is beyond me. It is an essential.


I agree with you that traditional drt is the most useful for most tree work. Unless I have at least 40' of clear climb it is a total waste of time. Even with 40 or 50 feet of climb it may not be worth it.
But on the other hand I have done some very large technical trees that required a couple of days and having a easy re-entry to a high work area is invaluable for conserving energy.
One tree in particular, I was in and out of it probably 6 times. It was over 6' dbh, and where I cut the top out was over 150' feet up. I came down for lunch, walked across the street and ate at a cafe with my groundy and a couple of nice young ladies, walked back to the tree, and ascended up 100' in about 5 minutes with out wearing myself out. To have spiked or drt up that high (with a full belly and tired) would have been out of the question. I would have just had to skip lunch, or have it sent up.

ok, i mentioned before that its more of a southern hemisphere thing, from what i read there are much bigger tree's down there, tall that is, i removed the biggest tree in the area, that area being northern toronto, it was about 165 but that was the biggest tree ive seen, and its a rarety to get to take down anything that big

it seems that our tree's in canada, excluding BC where the red woods grow, our tree's grow out more than up, they get tall 125 - 150 foot is tall but nothing in comparison to what ive heard about, My boss started in australia clearing hydro through the bush for a company in Brisban, and i always figured he was bull ####ting me talking about going up 150 feet to flop the top 50 foot out of a tree so that it wouldnt contact the hydro wires, but i guess not, my only question would be why he has no knowledge of SRT

The biggest trees in the world are on the west coast of N. America. Austrailia and S. America and Africa have some nice ones as well.
The SRT is pretty new in tree work. It has been crossed over from rock climbing just in the past couple of decades. Not to mention most rock climbing SRT is pretty new. I think the tree workers of the southern hemisphere just have more rock climbing influence instead of the tree work tradition we have.
