SRT Trunk Tie Off/Safety Concerns

Re: SRT the Flaw?

You don't have to trunk anchor. But in my opinion it's the simplest. I use two basic rope tricks. I have a video of the one on YouTube. The other simply is take everything off and pull your tail. Makes it through tight unions and is simple but more time consuming. ( I don't do this often) I think it's almost just as quick and easy to ascend back up in this instance. The other one I do more often. Like I said it's on you tube.
 
Re: SRT the Flaw?

I agree trunk anchor is the simplest for sure but is it the safest ? Honestly its something to be very concerned with but I think I would still do it for most jobs with the right people around me.
 
Re: SRT the Flaw?

I pruned a Locust that was topped when it was really young. It had 7 leaders growing from about 6' off the ground. The shape of it was like a 7 fingered claw with fingers pointing upward. I was able to climb one leader, work, jump to the other, work, jump to the other, etc... until I circled around the tree. I used 7 natural redirects to work the crown of the tree. And I was still able to pull my rope through!

Why 7 times? Mostly because it was fun and I could. But, mainly because every time I redirected I was now working with my rope verticl instead of being off to the side. It is just plain easy working with your TIP right above your head.

Sure, if I were climbing DDRT, I could have re-tied into the specific leader I was working, but the other point of re-directs is to distribute weight.

And of course, we all have the option (and in the case of the use of chainsaws it is mandatory) to secure ourselves with a flip line before we make a cut with a hand saw.

Why don't they allow SRT?

Got any vid you can link of you working a large decurrent with this set up?

For the record, I started this thread as a way of discovering why people are happy to use the basal tie off when working a tree SRT.

If Tom wants to change the thread title to 'SRT Trunk Tie Off - Safety Concerns?' that's cool, think its safe to assume most people reading will realise the thread is concerned about SRT for work positioning not access.

The thread title 'SRT the Flaw?' was not meant to imply SRT was unsafe. 'The Flaw?' was about the exposure of the downline and trunk tie off to accidental damage.

As Zack said, to have your anchor point below you flies in the face of everything we know. In SRT (with trunk tie off) we cut branches and timber and they fall down towards that downline which runs down the side of the tree and is tied off at the base of the tree. This (for me) is what makes the basal tie off seem unsafe. The likelyhood of a falling branch causing a complete severence of the rope is highly unlikely. But if a bigger branch falls down between the tensioned downline and the tree this is where it could become an issue.

One person made the comment about a falling polesaw, I've seen a polesaw (Silky Hayauchi, just the single extension) fall down through the crown of a tree and seen it imbed itself in a branch about 40ft below where it fell from. This is one occurence which would definitely threaten the life of a climber using SRT with the trunk tie off.

Also, imagine using SRT with two climbers in the tree. The downlines running down the side of the trunk, pruning cuts made near the main stem with the chainsaw etc. Probably not a good idea to use the trunk tie off in this situation regardless of how skilled the climbers are.

On the SRT issue in general - some people have hit on the important fact that pretty much all of us have DbRT hardwired into out minds. We're used to seeing the doubled rope in front of us. So you'd have to accept it will feel different.

I'm gonna be buying a Ropewrench but I'm gonna try and use it with a top tie in point. Will just have to work out various ways for line retrieval from the ground. For me personally the Trunk tie off for working around the tree just doesn't feel right.

[Unless you want the title changed, it stays as is]

When I don't do a trunk wrap anchor I have several alternate TIP retraction schemes.

Its rare that I will descend to the ground without moving my choked TIP down with me in stages. Various choked haul down schemes have been shared.

If I were to descend all of the way to the ground I would have tied on a throwline or small cord to the pull-down tail. this would have been sent to the ground, probably in stages so that it doesn't get tangled and in the way during the job.

I'll see what i can do. Its on my to do list but i don't have a good camera. Since you asked though, would it be more helpful seeing it from the climbers view (helmet cam) or from the ground, time lapse or a video from outside the tree?

Here is the link to the youtube video of the SRT rope trick
 
How 'bout in 3D surround sound with OmniVision and Dolby?


Derrick, you don't fool me ... you just fishing for the justification for your next camera!

just a straight up vid from outside the tree with any cam, no time lapse and no editing so I can see what you got. pref. while dormant.
 
Thread title change...note!

Grover asked me to change the thread title to:

SRT Trunk Tie Off/Safety Concerns

If my 'edit signature' shows up in your post in this thread its only because of changing the title. In this thread there is no other editing...so far, and I don't see any indication.

Very polite disagreements!

it was said in a broad encompassing manner, basically, I don't hire people who don't care :)

I feel ya. A friend told me recently, "fire fast, hire slow". But even guys who are really good mess up sometimes.
