Suddenly SRT basal anchors EVERYWHERE!!!!!!!!!!!

Re: Suddenly SRT basil anchors EVERYWHERE!!!!!!!!!!!

I'm sure it's been addressed in many of these threads before, but I couldn't precisely find it by searching so I'll ask for opinions: what about the risk falling limbs striking the anchored end of the rope in SRT?
Personally, I still ascend single line but switch over to double after ascent for working. Maybe I'm chicken, but I can just imagine the anchored end of the rope being damaged by a falling limb, or someone careless on the ground doing something dumb— while I'm helplessly hanging on the other end like a schmuck.
 
Re: Suddenly SRT basil anchors EVERYWHERE!!!!!!!!!!!

4est,

your concern is brought up at almost every discussion of ground anchors. There is validity of course for falling branches. If that's a concern an anchor point can be chosen in an adjacent tree. This redirects the rope out from the TIP and changes the load up there too.

As far as the concern about a careless cut by a crew member I eliminate that by not having that person on my crew. In my experience the person who can't understand the risk of compromising a ground anchor, which is no different than what everyone is used to for rigging anyway, that person is too much of a space case to have near me. Send them away. Use bright colored ropes and make sure that everyone pays attention.

If you still can't get that level of buy-in then a choked TIP would be a better choice.

Having the potential for doing a climber lower is just one advantage of a ground anchor. This is NOT a deal breaker though. In the case of a rescue, like someone has already said, there is a good chance that this will be a moot point.

What I can see in the case of a rescue where a climber needs to go up to bring the victim down is how another belayer could be enrolled to lower the victim in tandem with the rescue climber. That frees up the rescue climber to attend to the victim not lower them too.
 
Re: Suddenly SRT basil anchors EVERYWHERE!!!!!!!!!!!

Just wondering if there has ever been a known rescue from an SRT base anchor. I don't know how some of you can say rescue from a base anchor is bogus because of hitting limbs, lanyards, etc. if it has never been attempted.
 
Re: Suddenly SRT basil anchors EVERYWHERE!!!!!!!!!!!

Rocks, The best answer for this is that it is not out of the question to do a rescue with a ground anchor. Every situation will call for a diffrent variation for the rescue. So even if the ground anchor wasnt so great for one rescue it doesnt mean it wont be great for the next. It's really all going to come down to who is doing the rescue at that time. What ever way that person goes they had better be trained and ready for that moment. Your never going to be able to go back and do it again when it counts.
 
Tom,
Are you saying to place a LRH, in the case of having to lower a climber (this way you can then at that point place a descender onto the anchor, release the LRH and then lower the climber)?

I don't know what you mean???

Using a LRH in place of the pile of half hitches makes a neater setup. Its also easier to release the load under tension.

Read up on LRHs and decide if they can be used in your setup. There are soooooo many combinations that its hard to show all variations.
 
Tom, GREAT suggestion.

There's easy room in the rings for the extra turn of rope and the Munter lets me hold virtually all the force I can lay into it. It's almost like a mini-progress capture system. Now the girth is so tight I can't tuck in a tail!

Thanks.

Does anyone add a deceleration device (Screamer, etc) into their anchor. I am comfortable using a Rig, l'd etc with mule backup. I also have trained and skilled ground workers that I trust with my life. The extra friction knot backup seems unnecessary to me and complicates the system.
 
I had a Screamer incorporated into an early Unicender tether. After doing some load/fall calculations I realized that my rope had enough stretch in it to not need the extra release of the Screamer. If I remember, in rough numbers, a 200# climber would have to do a free fall of 'way too many' feet inorder to generate a load high enough to zipper the Screamer. Our TIPs generally flex too which absorbs some of the fall load.

I would NEVER climb SRT without a friction hitch back-up.
What if the person lowering is swarmed by bees, gets attacked by a dog, or??
I know the chances are remote, but I insist on a back-up.

What rope?

Fly, KMIII and now Tachyon

Of the three is Tachyon the most dynamic?

What % of buzzers using SRT back up there basal anchors with a friction hitch?

Those that do back up, what is your friction hitch of choice? How do you tend the hitch when lowering?
 
More or less the same for climbing, as far as the stretch that I feel. That has never been an issue though. Other things, to me, that make me like a rope.

I don't back up my trunk tie.

I put a sling around the base of the tree, and attach a rescue f8 and a single spliced eye Beeline tail on a carabiner. (It is a barely used tail that I had before I switched to i2i tails). I tie a 5 coil blakes hitch, run the rope through the f8, and then do a "hard lock" on the f8.

This is my variation of a ground lowering system. Not easy for the groundmen to add extra rope into the system, so I plan in advance for that not to be required.

It's a system I put together with extra gear I had lying around. Not an elegant system, not particularly fast to setup, but it's cheap.
 
I'm late on this thread and haven't read it all but I use a simple running bowline plus a tenex sling with an 8mm Tech Cord prusik configured like a short footlock prusik.

I'm not sure the lowering feature means much to me since I'm guessing I'll be on a lanyard when whatever bad thing that's gonna happen happens.

I'm liking the ring-ring cambium saver idea for a retrievable high tie-in. Haven't tried it yet though.
