Learning the cuts

Here's my favorite shot, my favorite crane guy's new crane. It's a new Altec 38 ton (marked down to 35 on this size rig) with 138' main boom. It's on a Sterling with a Mercedes engine. Big Pimpin! /forum/images/graemlins/jj.gif

There's one peice that looked like it may have flipped a bit? Soon we will be getting a new crane wish we could have one like that! It looks perfect for residential work. Big money. Did you remeber how to put the spurs on correctly?
 
Nope, no flippin that day. Just the usual spin and twist stuff. It was a smooth day.

Sweet Mark!

wish our boss would rent us a crane some time. we seam to do everything manualy and just with a banditt 150 chipper. Be nice not to have to load so much firwood by hand. seams like u guys use bigger chippers too.

that white crane is one of the best I've seen.
 
Thanks Mark,
For more than one reason I'm at a point where I don't get the opportunity to do many removals, which is not where I want to be. I think the pictures you guys post are one of the best things about this website. Before I came on treebuzz I used to do searches like "crane tree removal pictures", or I'd type "Chisholm crane removals" too, cuz I heard it was one of your specialties.
I'm still very 'green' with removals, so when somebody tells me that the tree to be removed has my name on it, I get mixed feelings. But the feeling that always wins is that I wanna be a big tree taker downer damn-it! I'm a little scared, but I'm goin' up!
 
That crane in the pic would probably be about the best all-round size for tree work. The bigger the better for some jobs, but 138' of boom and 38 ton is pretty much the most usable for everyday stuff. The carrier is still narrow enough to sneak in between trees and such.

The most used crane for me is the GRCS! It can fit through a 36" gate! /forum/images/graemlins/wink.gif
 
I wouldn't say that it is one of my specialties, but I do think that you should do your homework before taking on crane jobs -or big removals for that matter. I just try to keep learning. It's the best way to remain safe and effective!

Being scared at your stage of the game is pretty normal to an extent. The one thing I would say is to envision what the outcome of every cut will be but be prepared for the opposite. Meaning, know what should happen if it goes your way but look for what might get you or you crew and be prepared for it. Even the small things could hurt!
 
I really wish I had pics of this tree I did 2 weeks ago. Not a real tall tree but beefy and real dead. The kind where birds look past it to perch. Anyway, all limbs out by lunch, which were trees themselves. Got down to trunk section where the leads branched out. Choked on one side to open cut so it didn't pinch. Used a 066 with 32" bar. Had to walk all the way around tree to complete cut. After it came off the piece dipped down with all the flex and stretch. Looking at the cut afterwards, you can see where the tip of the bar had just made it to the center to make a clean cut. The piece weighed 11,500 @ 7ft. tall. The final cut was 11ft. and 13,500. The point is, is that if you don't choke and cut right your getting crushed. The piece that dipped when I cut it would have crushed me if your not in the right spot. When an "accident" happens on a crane it becomes catastrophic. You don't just get hit with some brush. Learning cuts also means learning total failure if it were to happen.

Knowing the operator helps with knowing what cut to give him too. The tree above is a good example. Operator says he's good for about 9k. So I asked him to double the line so he can winch more and I gave him those pieces above. Our whole crew knew you could take more. Nothing wrong with being cautious, but I don't want to be sitting more than I have to.

Damn man. Our biggest/baddest guy slings a 046 around like a superhero, but I've never seen anybody up in the air with an 066. I can barely pick the **ucker up. Don't forget the pictures next time. /forum/images/graemlins/ukliam2.gif. Sounds awesome!
 
There's a lot of fat trees out there. Rob's area is full of 'em.

I did a crane job a few years ago that was a fat Pin Oak. It stretched over four yards (it stood in the backyard). We used a 75 ton to wreck it, but since we had to park it in the front yard, the capacity went down bad.

When I got to the main trunk, I had to use the 088. With the boom angle, I had to cut 6 footers. It took a long time to widdle it down. One cut with the 088 is tough enough when you're on spurs, but to do four or more- it's the hardest part of the whole job. This Oak was 19' circ. at chest level.
 
....and an 088 I can only try to imagine, cuz I've never seen one. Gees louise. My back hurts just thinking about it. /forum/images/graemlins/bigcry.gif
 
Here is a pic of job we did at Stanford University in CA. We had two 75 ton Grove cranes rented to remove 8 Eucs and 1 Oak. This piece is cut right above the outrigger ram. It weighed in at 8 tons.
