I don't use this technique enough....it's an awesome and creative rigging system when you have 2 rigging points over top of the piece to come down... it has a lot of applications. Can also be used with various pulleys instead of the ring... lots of options.
Climb High, Work Smart, Read More.

Spanning and speed-lining are overlooked as options a lot of time in certain parts of the world. What we need to realize as climbers is that EVERY technique will play a role at some time or another. It is up to us to learn and know them. Stay safe, Patrick! I love what you are doing for the community!
Appreciate it! - Patrick
Your company should be named RIP Tree Service. Since you’re always working on cemeteries Lol.
Good stuff.
This reminded me of all the summers working as a teenager with my father and brothers growing up.
We had a 55' bucket truck with hydraulic chainsaws that would cut threw the wood like it was butter.
The basics are all the same. We just have more flavors of Gatorade now. :)
I still think lemon lime Gatorade is the best. LoL
Stay safe and cool friends.
@@briankennedy1313 Sorry to hear that @Brian Kennedy.
Hay Brian I think the more things seem to change the more they really are the same. If you take a closer look.
Here is some eye candy for you friend. Enjoy :)

Yep, I was just talking to a coworker about not letting down tip tied pieces until they have completely popped off. On that note, I've recently been cutting about 2/3 deep downward angled undercuts (ideally toward direction of rigging point) on tip tied upright pieces recently and making even steeper back cuts to meet the deep downward angled undercuts so they slide off butt end first and reducing shockload. It's sort of like spear cutting but for wood that is too fat to spear cut in one go from top down, so you make two cuts.
great technique, I get a little nervous with the one running bowline knot on the piece.... I've had the knots open and pieces come out. I almost always put a half hitch before the running bowline to help pull the knot closed and keep it tight. Took me a couple years before someone showed me that to keep the knots tight. Works really good with short stubby pieces, the long ones like you cut have a little length before the knot can come off so the danger is a lot less.
What was that termination knot / hitch ? Good video ✌️
Pretty cool. Much smoother than negative dropping. Definitely not something I would try to set up unless I really had to with out a bucket though
Yea man. The LAST THING i feel like doing is climbing back up there. but then i thought...what about a basal anchor??? WIN. Especially now that i have a big shot.
When you have to funnel the removal through a bunch of canopies underneath, it’s definitely worth the added minimal climb to save hours of energy fighting with hangers
What knot did you use on that top cut and why not the normal Daisy chain?
Why rigging ? Its nothing down ...its faster to do little chunk ...of wood ...
Seriously man, I've watched you tie the knot around the stem you're going to cut 100 times. You do it so fast, it's hard to see. But, it looks like a slip knot, safetied with a bunch of other slip knots? Is that right?
Running bowline is the knot he is using
He has a video showing it, the daisy chain knot
I used both the running bowline and the daisy chain hitch in this video... I have both of them on my channel, under the knots playlist: ruclips.net/p/PLWtbeZGrAcB4-DouSOl4XRhN4vNrHW6iL
@@TreeMuggs_PatrickM Thanks, mate!
The groundcrew have different coluerd helmets. Is that planned to keep track of each other?
That's a great idea
Nice video. Never seen that type of rig before. Also, your groundie at 17:11 has huge balls grabbing the bar on a saw that's running like that. 😆
6:08 what knot are you using to secure that piece?
"Helluva job!" Love the raw footage. Thank you as always sir.
I whistle all the time when I'm up there in the bucket.
This might come in handy this week.
Thanks for the vids as always Patrick. My question is what dictates the use of span rigging? The layout of the tree, the wood being removed, obstacles below? Thank you.
I don't use it often, really depends on the structure of the tree for me... - Patrick
The people laying there really pushed up hard on that tree.
Why Whistle ? To show how is esier ...?
Span rigging is a good tool to have in the tool box but you should be cautious of the forces it applies to the system. Your first couple pieces, the rigging span is nearly horizontal which will apply a force multiplier of over 500% at each of the rigging points of the span. The rigging point to the right, where the rope redirects down to your lowering device will see an even larger multiplier because of the anchored line. Span rigging does not become beneficial from a force multiplier standpoint until the internal angle of the dangle is 120 degrees or less. This image illustrates the angles and the forces they apply.

This also illustrates why a double whip tackle is so beneficial. It's internal angle is 0. Effectively cutting the load felt by each leg of rigging in half. Your first couple pieces applied a larger force until they were lowered enough to reduce the internal angle.
Outside of the force multiplier of span rigging, span rigging is great for creating a lowering path that wouldn't otherwise exist.
Stay safe and thanks for sharing.
Thanks for explaining that....I once read that mathematicians don't do ziplines, because there are points where the math theoretically goes to infinity... - Patrick
@@TreeMuggs_PatrickM I agree with the above comment. You must be mindful that as the span line approaches (of course it never gets there) to horizontal; the force multiplier effect is at its absolute max. In Rope Access this is something we always think about as the stress on anchor points is huge. 45 degrees is generally regarded as the max angle.
But - I love this video, reminds me I need to use this technique more for tree work.
Span rigging is pretty awsome, definitely has its place! You are deadly with the snap cuts too Pat! I need to work on my snap cuts on larger wood i have to double back to cut more and go back up to try and push again 😩 in the bucket which can put me in a hairy spot sometimes. Nice work Pat, thats what I call a good time there my friend!
Thanks brother 👍 - Patrick
joshman, I find myself having to go back up from time to time as well!!
That’s excellent I never thought of leaving the ring on the rope. That’s always why I don’t span rig to much because I have to keep untying the tie in point of rigging line
If you're using a ring don't you have to thread out the whole rope?
Nevermind I get it. Is it more advantageous than a pulley? Also I've been told span rigging is having lowering on both anchor points. If that's so what do you call it when one side is fixed?
Cringe at the pinched bar and ground guy lowering before full separation, but great exhibition of the concept. I want to make a redundant, minimal extension anchor system
for this kind of situation, like a rock climbing quad but huge.
U need a grcs 🤣🤣🤣🤣👍👍👍nice job I like the concept thinking outside the box
Oh man. I dig it. I'm just a one man show for now, but I'm slowly investing in rigging rings, thanks to your podcast with the X MAN! You've ruined me.
Thx for the video and inspiration. I had asked for help on it but I called it high line rigging. Y’all make it look easy. Keep up the good work. Xcited for the next one.
Awesome
cool Patrick, I see stillborn using this technique a lot. I'd like to try this out. thanks for sharing
I just found this video. Great Stuff! Where did you purchase your X Ring?
One day I’ll know the luxury’s of a bucket truck.
Beautifully done. Ace 1 👏🏻👍
Why not negative rig? Seems this takes a lot longer.
Simple and safer. Good work!
what length of rigging rope are you using?
Nice vid! Is that a Safebloc above the pow?
Nice work Patrick. Awesome 👍
so smooth w the x-rigging ring. very cool!
I've seen this technique used in videos, but never put it to use on my sites. Just curious what is the highest value of this method? and maybe what situation would you prefer it in most? Looks great, nice work BTW.
Let's say the tree is In a tiny backyard, the ground guys are gonna cry trying to process big limbs. So instead of lowering it to the base of the tree, you 'span' it over to the driveway to where you can grab it with the claw or whatever.
That is cool I can,t wait to try it
Slingshot!
Well done.
I noticed the Huskie you switched to half way down, I just picked up a 572 xp a month ago and on the second time I used it it started dying at idle and then completely would not start. I took it back and they replaced it with another saw. Last week it also started to do the same thing. Truth is, I Actually LOVE the saw as far as power/weight and the vibration grip is amazing, so I'm bummed that I'm having so many issues... Have you had any trouble with yours Patrick?
The Saw is autotune ?....if so...you need to reset it...
I haven't had any issues with my 572 yet, but I've had all kinds of issues with 540's... Gotta be all the electronics in them ..... - Patrick
Name of tool he's using to turn the log at 15:34?
that's a Cant Hook, highly recommended
Why all the rigging? Nothing but open space below you, that's weird.
The open space was an asphalt road... - Patrick
@@TreeMuggs_PatrickM I said the same thing but I felt it had to be paved for that application. nice work man. what size rings and rope do you use for that. 5/8 rigging line with a 5/8 normal sling on your rig ring?
im saprised ya guys werent just reducing on that leador ya took off what brought ya to just remove the big leador
$$$
My view....Two previously removed branches with subsequent compartmentalised plug offs n probably rot and it looked a thin x section nr the junction. Hanging all that over a public? Path too....you’d only have to revisit in the future and its work to keep an eye on all this, better to sort it here n now ....
It would help the viewer if you explained the job. Why are you taking off such a significant part of this tree?
Nice rigging
🤘👌
How does this style rigging effect the stems in terms of force? A simple straight stem negative rigging setup can handle unreal compression force, but this looks to be pulling down on one stem more than inward toward each other as I thought it would. I've wondered about setting up a system like this on pecan trees because they often don't have a good central lead. Always enjoy your videos, thank you for sharing.
There is a tree stuff seminar on here which covers your question. Its from the lockdown so maybe a month old. Drawn out but worth a watch
@@markwilson6663 Great, thanks.
In this one, I tried to set up both stems in compression as much as I could.... I really like this style of rigging depending on the structure of the tree, it can open up all kinds of options..... - Patrick
So a guy working in a bucket at a cementery just died, was that you?
