Carry Over from Work Photos

Steve Connally

Been here much more than a while
Hey there. As requested by Levi I am carrying this thread over from work photos concerning the oak I did. So Levi I've tried to carry over and draw some diagrams. Yeah I suck at it.

So as to orient us to the tree lets refer to one side of the fork as crane side and the other as neighbor side. Crane right.

The split was awful and as I stated in work photos it was getting worse daily. The split went all the way down to the old pruning cut with the suckers circled in photo one. The crack was open on the crane side though not as much on the neighbor side. That lead me to think more holding wood on the neighbor side and more weakness on the crane side. In my mind the tree had found some sort of balance between rot, holding wood, and gravity. The wind was from the west (straight ahead in the picture) so the crack was being pushed open and closed in a fairly straight line. Had the wind been from north or south I think I would have seen one side open more than the other in a rocking motion.

Picture 2 is what I think was going on. It found balance. All forces aiming in the same direction, down, based on balance of the limbs being fairly same in size.

Picture 3 is what I thought could happen with the removal of the crane side all at once. I figured it was possible the "distributed weight" being fairly equal would be upset with the crane side removed thus creating a sort of lean or twisting motion from gravity alone heading to the neighbor side. Lind of like felling a codom trunk. It'll fall straight with both leads but remove one and it'll want to fall heavy on the remaining side due to loss of balance. My thought was instead of weight being distributed evenly its now weighted left with no "ballast" and could the rotten wood on the right provide tension wood against the failure?
Again, remember we are only taking about that forked lead, no the entire tree. The rest of the tree was not my concern. My concern was upsetting whatever hostile situation the forces of nature had created. I did not want to be the trigger of this thing crushing at least one house and possibly 2 taking me with it or me getting fragged by an exploding chain.

I understand based on the simple fact of removing any weight, the lead is less likely to fail. But I kept asking myself what should I do to keep this thing as balanced as possible since it only seemed a little grumpy in that position.

I'm all ears. Like I've maintained, I am no expert at the sketchy stuff much less everything else. This was a learning experience. Fortunately or unfortunately even the next one like this won't be the same as it's all based on unknowns like decay and things I cant see inside the tree.

Now, I wanna learn here so no worries about hurt feelings. Lets get something out of this discussion!!! tree1.webp tree22.webp tree23.webp
 
I'd also love some input from the guys who've been around for a long time like Roger, Tom and Treevet. Bet they've seen a bunch of stuff like this over the years. Not to short change anybody else with years, just the first 3 I thought of.
 
I have no experience with cranes, but I originally (in the other post) thought you meant taking weight off of both sides of the tree to keep the split from failing and I couldn't wrap my head around it. As you have it drawn here makes perfect sense to me. Still just a guess, but I could see with all weight removed as you show in the last picture that this could cause it to rotate and tear.

Sometimes a picture really is worth a thousand words. I'm interested in everyone else's response as well.
 
I think that without the crane, dumping big pieces off of anywhere on that tree could easily have caused enough stress forces to bring the thing down in two very large pieces. Now, the crane can lift the pieces up and avoid nearly all of the problems, but without it, you'd really have to watch what you were doing. There are forces within the tree holding it together... trying to both pull the split apart and pulling it closed. That's energy... lots of energy... and suddenly releasing it is exactly the carnival ride you take when you drop too big of a piece off of a lateral stem. Bbrrrrrroooiinnnggggg! So, you could make the tree fail whacking big stems off randomly, but... lifting them off with a crane avoids a lot of that sudden energy release (because there isn't all the weight of the piece amplifying the oscillating forces).

What you're showing here makes perfect sense to me. Even with the crane, that's a dicey tree to remove.
 
i would set lines to get a feel for the wood. pull in all directions.
It would be interesting to see some of the pieces. base of split up.
sounds like it was pretty close to the tipping point splinter splinter and big ol fail at any moment.
The most important thing I know is when there is no movement or it sits static is when extreme caution is warranted.
Like the pencil in your hand that suddenly and unexpectedly fails.
Don't be fooled by a tree that isn't moving. Gravity always wins.
 
So if this were to be a clock face and the crane side is 12 o'clock to 6 o'clock, and the neighbor side is 6 o'clock to 12 o'clock, it would not be good to take a 12 o'clock to 3 o'clock.

That would twist the crane side leader. Starting at 3 o'clock would take the most leverage off of the fork, all else being equal, reducing the load, without imbalancing the crane side leader. Then do some of 2 o'clock and 4 o'clock. Then do 5 o'clock and 1 o'clock. Then move to the 12 and 6 positions.



I don't think that in all cases removing weight will reduce likelihood of failure. You can create imbalances that will result in torsion.
 
Exactly. The thought was if I took the lead away from the crane neighbors side where the holding wood was, if it failed it would fail towards the crane. I think that's the same thing you're saying.
 
The funny thing is after I pitched a fit he hung the other climber and he cut and chucked tips. He didn't tell me that was his plan. On a side note, the other climber has experience but not in a good way. His saddle looks like something from WWII and his rope is trashed not to mention his flip line. So he hung off the ball with no rope and had the shackle from the rigging strap through his d rings and no flip line attached. He was hanging off the hook not above the ball. At that point it was fruitless to even say anything since me and the boss just got done yelling at each other. I just picked up a rake and faced the other way so if he fell I didn't have to watch the carnage. Sometimes you just can't sell someone on safety who has gone years doing it this way and never had an incident. Luck has translated to acceptable practices in this case. I'm studying for CTSP and trying to share that knowledge to make it a better place and to protect HIM when OSHA comes by. A lot of stuff falls on deaf ears. We always did it that way seems to be the mantra. I keep trying to leave my mark by making it a safer and more efficient company. It's an uphill battle. At least when I do it, it's my way, the safest and most legitimate way possible that I know.
 
Hey, I'm close to top of the pile around here!! This isn't a progressive market and its flooded with hack climbers that will climb cheap for beer money. Cheap sells in a removal market. All I know is he doesn't put me in those positions and what happens when I'm not there isn't my issue. I can try to help as much as possible and do things rite when I'm there but ultimately I'm just a guy who gets a paycheck so I only have say in my own situations. I have no ownership other than when I'm on the job so it's not a bother to me. Things are fine on must days when I'm there and especially of I'm climbing. This for sure isn't my dream job or end game but there isn't anyone else worth moving to that will pay me what I'm worth. The other crane gig in town top climber gets $18 an hour and one of their groundies carries a pistol on the job site. This area of Virginia is a shit show for tree work. There are dozens of companies out there and most are hacks. The good ones won't pay. I'm not sure about north of me a bit. There is a company in Newport News that seems legit and has a crane but IDK. No rush to make a change. It's livable and I'm comfortable with my own safety when I'm in control.
 
Steve, I wanted to ask you about running that brush mower. Do you run it on that articulating loader? I put one on my 540 and got very frustrated in a short time with the lack of performance.
 
Yes its run on the swinger 2000. It drinks diesel when were using it and it works best running the machine in reverse. I'm not overly impressed but it beats running a chainsaw bent over all day. I think theres a better mousetrap.
 
Thanks Erik. Had I not had the crane I probably would not have used this as my test tree for rigging situations. I can always appreciate those who have a lot more experience with bad trees than I do. Unfortunately I don't have guys like you on my crew to walk through the job.
