No Rob, that's not what I'm saying.

Thanks for the info James. Maybe I didn’t hear wrong?

In looking at the Link-Belt’s load capacity chart, when the boom is fully extended to 115’ (without the fly) and with 16 k counterweight, at a radius of 65’, the crane is good for 12.5 k over rear (unless I’m reading the chart wrong).

Maybe this is how far back from the Pine we were at, I don’t know, as I did not measure the radius, nor to be honest with you, did I closely inspect the counterweights. I just went by what the op told me.

If you look at picture of the setup (which I’ve attached again), when I’m talking to the crane op, it sure looks like it’s further out, maybe 80’? This would bring me down to 9,000 lbs with a boom angle of 44 deg. Pictures can be deceiving though, as the tree was uphill giving it a perspective that makes it look taller and further away.

What do you guys think?

I don't think it matters much either way. The chart tells it all, so I would assume that you were 65' radius not 115' as some thought you meant. Doesn't look like it is less than 50* boom angle from that shot, but either way it was coolto see Chris. Thanks for posting.

The one thing tough with that style of crane is how long it is. We used a 75 ton Terex years ago just like that and had to pick from the front yard. Since it was so long we had to pull the phone lines back with a rope becasue they would have rubbed on the winch during the removal.
 
No worries Rob. I appreciate everyone's input as it makes me think about stuff that I may have missed the first time around. The info that you and everyone gave me at the workshop last fall, as well as what I picked up down in PA this spring from The Crane Man (Pete and his crew) really helps with my crane work.

It's especially good to hear from crane op's like yourself and others who have both a climbing and operating background. That experience is priceless IMO!

I have no intention of operating a crane myself and that is why I will listen intently to what a crane op says, to a certain extent, provided I know that they have experience with tree work. When we were at the workshop in PA, Pete stressed how important it was to keep the communication going between climber and op, and this is so true. Mark and Dan said the same thing last year at the workshop and I can see how important it is.

Keep the info coming bro!
 
Hey, nice to see a Link Belt represented on a tree site. I've been working the 8670's bigger brother for a few years now-but have never seen many other Link Belts being used for trees.
 
Hey 343, good to see you here. I read alot of your posts at AS. Stick around, we need another good crane guy here!

Nice work, Chris!

It extremely nice, if the cranoperator can estimate how much he has to preload the picks. Nothing worse than a stem flying away after you cut - and waiting for it to come back down again! Have tried that a couple of times with bad operators! Not doing that again!
 
I agree and I have nothing but good things to say about TM Crane. These guys have worked with trees for years, and they know their weights.

Funny thing is, tree work is only a small part of their operation.

Check out their website. A very nice family run business.
