Releasable Trunk Anchor

Worthaug said:
One thing I'd like to add or remind people of is that a basal anchor does not have to be connected to the work tree. It can be set on a remote tree and when the climber gets to the tie in point they can lanyard in and unweight the basal leg of the system enough to generate the slack needed to add a midline attachable canopy anchor (I prefer the alpine butterfly/ pinto method). Now the anchored end is not life support and the tree can be worked like it's canopy anchored.

Yes, Conversion and Release kinda go along the same lines, I don't see what tying the anchor to another tree has to do with it but your anchor has loads of good benefits.

For me I try to use up every bit of rope while I am working so tend not to leave draped retrieving sections. These days I cut ropes in 2.
 
I made the assumption that you felt that basal anchors were for ascent because when anchored to the work tree the standing part of the line is in risk of being severed by the climber, the ground personnel, or a cut piece. By anchoring to a remote tree one can reduce this risk during a pruning job or switch over to a canopy anchor for a removal job (which requires eventual untying of the basal anchor...)

I guess I was think about work climbs, but, Moss has shown us that releasble anchors can be invaluable for rec climbing.

Yep, it's very rare for me to use a releasable anchor work climbing. I usually stay basal anchored through the majority of my pruning climbs and rope length is never an issue, I tie on a second rope if needed. I also try to tie into a tree away from the one I'm working in. If I'm worried about a ground worker contacingt with my lifeline I'll still set my rope like a basal anchor on a lower limb in the crown.

Without wanting too much of a faff I wonder how the dropped end on Erik and my example could be controlled to stop hockling, twisting and generally getting stuck.
I used the trt/hub release yesterday, just rigging winch pulleys, but it meant the climbing rope could be stored well away from the rigging through the day. It released sweet enough, the 8mm tends not to get hung up, perhaps because lower friction on obstructions?
Worthaug, unlike Moss I work exclusively on crown anchors, I dont mean to say trunk anchors are not for work, just that they have different parameters.
 
You only climb large trees? You never have a tree to work on with one or a few target limbs? You waste the time to climb all the way to your tie in point to switch over to a canopy anchor? You never climb young trees with just two lanyards? You don't ever use a high tie in to remove an adjacent dead tree? You just do arboricultre in the movies? Quit over thinking shit and just work dude!

Yep, I think releasable anchors make the most sense for rec, research, expedition style climbing where weight matters and bringing less rope into the woods makes a huge difference. All the closeted solo work climbers out there ;-) can make use of releasable anchors, but no one ever works solo right?

I solo, too... in fact, I rarely have help. Sometimes the wife will come along (strong woman) and help with what she can. Mostly just unhook the drop so I can pull the rigging line back up, drag what she can, unhook a saw from haul line and attach a bigger one, and keep me company. If I had my way, she'd work with me full time. She's not afraid of work and she's my best friend, so we never argue or get pissy with each other.

I also enjoy the art of solving the problems of solo work. Tree will keep you in shape, the tasks that need to be accomplished will keep your brain from going soft.

Oh boy, out of the closet, yeah solo works for me for many pruning jobs. It is fun coming up with cool static rigging setups when needed, also speedlines come in handy. But... how many solo workers love cleaning up the brush? ;-)

Hypothetically, you could climb in the afternoon, and hit the cleanup in the morning. Hypothetically...
 
On large diameter dismantles, I will occasionally send a running bowline up to an isolated crotch, so I can re-position my climbing line and move my anchor point as needed. A self retrievable basal anchor is a bit unnerving to me. Of course I don't mind watching you ginepigs. o_O

Ummm.... It's so much fun untangling a massive pile of brush because for some reason it didn't go away after you spent the day in the tree. Can we bow our heads for a moment and be thankful for awesome groundworkers?

I think... the releasable anchor makes sense when you're short on rope and you need to convert to a canopy anchor, and you're solo. It's never really a problem running out of rope on a job, it shouldn't be anyway.

We had a chat on site on friday morning, we call them 'tool box talks' in the UK. None of the lads had ever seen a self releasing trunk anchor or felt the need to have one beyond asking a groundworker to untie their rope. The conversation kinda steered itself to different ways of release and we ended up talking about and looking at floating systems. With my twin ring loop we rigged up a floating Ddrt, SRT with knot block and TRT. Floating systems are interesting and they all release.....they've kinda become redundant but I love em!

I walk away from piles of brush just like cool guys walk away from explosions.
