Canopy or Basal Anchor? When and why NOT to use a base anchor, for SRT canopy access | Arborist tech

A quick demonstration about the differences in forces applied to a tree when
climbing on a basal anchor compared to a canopy anchor. This video clearly shows how easy it is to accidentally tear out a top with just body weight when climbing SRT with the wrong setup. Climb safe out there!

"Isolating the branch can take as long as the pruning" Amen to that!

I started watching your videos a few days ago and I like them. Im just a hobbyist climber and I do my own tree work around the homestead. I have a arborist friend whose shown me a little bit i like watching videos like this to learn a little more. Thanks for taking the time to make it.

another advantage of basal anchors is the possibility to share the load between branches all along the length of the trunk, or even between two adjacent trees; this provides some redundancy (if a branch breaks, several others should catch the fall) and can be used to redirect the force in compression along each limb

you can get knocked off if a branch break and falls on you head, dont use neck tether

@Stridertrees 3 жыл бұрын

Definitely a point to consider ! Most often when I’m using a basal anchor what you mention is the reason why. And sometimes it even makes for easy access on opposite sides of the tree if I just switch ends of the rope after finishing on one side of the canopy

@@birdisinfire I'm not saying you should be careless about your anchor point(s), but having a branch smack your helmet still sounds like a better outcome than falling all the way to the ground and I can't say I'm a big fan of neck tethers, although if your system stays close to your harness you shouldn't ever end up hanging by the neck. Anyway I don't use one but if I were to, it would have a pretty low breakaway strength just in case

I prefer canopy anchors. I use a quick link not a quickie because it has no problem side loading like a quickie but it is heavy. I can throw and advance with the quick link and it is heavy enough to easily come back to me. When the end is light I feel like I'm whipping the slack up the tree for ever, lol.

Im a newb...but im already doing some unique things. A technique im using u havent seen elsewhere is base anchoring a rope with a pulley at the canopy. I like this when i cant isolate one branch. If one does break im over other ones. I can put my climb line through the pulley single or double and haul up. Very retrievable. And if i prusik the pulley to base line... It becomes advanceable higher in the canopy. Thoughts?

Be extra careful with basal anchors. There's a considerable risk of cutting your rope by accident because you can't always see that side of the rope that is going down.

I am a heavy climber and almost exclusively use a canopy anchor due to the forces applied to the tree.

@Stridertrees 4 жыл бұрын

It’s good you’re aware of the forces ! If you use a big shot or are really good with the throw line often you can get through a few bigger unions to spread the forces through the canopy for a very secure BA as well. Just another tool in the kit :)

u go a little lower on my acess base anchor deal im 240 in my birthday suit so its gota be beefy but i canopy achor across two tops an makesure that i have a jiant crotch that cancatch it if both tops break or i tye my canopy anchor off as a back up witha chunk of rope that tyed in befier wood just under the tip

@Stridertrees 4 жыл бұрын

Yes John that’s another good way to stay safe, spreading the load through the canopy can be a great solution

@martinirving3824 3 жыл бұрын

Base anchor = mechanical disadvantage in that twice the force is being applied in the tree. The idea that limb movement can be captured through friction and force reapplied is definitely something to think about especially as the force could be twice the gross weight of the climber. What about two ropes - one to ascend and one to work with? Could do old school double rope and descend all the way. No trouble with retrieval but it's two ropes to put away. But I suppose the whole idea of single rope is expedience?

@Stridertrees 3 жыл бұрын

Sometimes I’ll access the tree single line and switch to double once I’ve reached the top either by disconnecting the base anchor or using a second rope, but it depends on the tree. Single line can be easier to move through a canopy because of simple redirects and the doubles rope problem of increasing friction as branches rub on the lines.

@dratsieservices8928 Жыл бұрын

It sounds like the big thing to worry about is loading limbs incorrectly and multiplying friction that can then break limbs. If I understand right. Canopy anchors would pose a similar risk to base anchors if doing multiple redirects that end up loading branches in tension instead of compression? If anyone has insight please comment.

@hunterpricepepe Жыл бұрын

Canopy anchors can multiply forces on your tie in depending on the angle of your redirect. If you redirect above your tie in, you are force vectoring those two points potentially causing them to fail.

Hey buddy is it OK to use a Carabener to tie as srt up in the canopy around the limb. For a canopy anchor on a split tail

@Stridertrees 4 жыл бұрын

I can’t be sure based on your description, but I try not to choke my rope off around a branch with a carabiner because it tends to side load the biner in a way it isn’t designed, and that can lead to premature failure of the hardware.

wouldnt a friction saver solve this problem? it wouldnt allow friction to hold the limb flexed. Note im an armchair arborist

@tomgosy 3 жыл бұрын

Using SRT with a base anchor means you can avoid putting hardware into the canopy, so using a friction saver would negate this. Also, the same forces would be involved, and you'd want to avoid those
