Building a ramp for a crane

[easyphloem]

Here is the driveway

This is looking down from the middle of the driveway.

This is a series of pictures that show the extent of the death involved with all three of these Oaks. One is hovering over the house, the other is over the guest house, and the largest is near primary power lines. Oh my.

Again. Big time importance in getting the crane up the drive.

Couldn't they have waited a little longer before contacting you? Just a little more decay and they would be perfect.

That said, the driveway looks like it may be possible for an ATV, maybe even a 70 ton like the one shown in NoBivy's photo, to get in there. Though I'm not sure that particular one has the adjustable suspension like Mr Ed mentioned, which may be very helpful going up a slope like that. Good luck, whatever you do. Prepare for shrapnel. You might hang from a basket for a little while getting some floppy deadwood off, if there's anything that might get broken by falling deadwood (like yourself). You could do the breaking cut that Reg mentioned in another thread, but still, if there's a house under it you probably don't want big dead limbs falling on it as the tops flop off.

No need for the tops to flop off.

Here is a tree of about the same size as easyp's, equally (perhaps even more) dead, full of ivy, and had to be got by reaching over power lines. Below the tree there was an old cemetary that was being restored, so the client did not want anything to fall and (potentially) break a historic headstone.

 

[Mahk_Adams]

(Almost) every piece was rigged with multiple slings so that when it was cut it barely moved...

 

[Mahk_Adams]

...and then the crane floated it gently away.

Cool.

But why all the attachment points? I see no targets close enough to warrant all the extra rigging. So what when it shifts/rolls a bit?

 

[Roger_Barnett]

One tie point high enough to not flip that section could have easily resulted in breakage, Butch.

Looks like a dicey one to climb as well, Mark. Of course, with smallish pieces being taken delicately, the climber's weight is rather negligible. Still a diceroll, imo....

Better view of some of the headstones.

 

[Mahk_Adams]

Closeup. The tree is about 34 inch DBH.

This was the first phase of the restoration so there was still a lot of undergrowth. We were told that there may have been more headstones, plot lines, crypts or other artifacts that were hidden in the weeds. When I first looked at the job the client asked if we could remove the tree with as little impact as possible. In order to avoid any pieces breaking out as the tree was dismantled we rigged each piece so that there would be minimal movement (shifting, rolling) when the cut was made.

VERY professional and delicate work Mahk. You are an excelent arborist!

You're right Roger. It's difficult to see, but the climber was attached to the boom of the crane in all of the previous photos. The climbing line is a little more visible in this photo.

 

[Mahk_Adams]

After all of the limbs had been removed the tree was deemed stable enough for the climber to disconnect from the crane and rig the trunk pieces while attached to the tree.

Does your lanyard in this photo have a weak link of some type in case the tree were to break out? I see you are tied into the crane.

Great job.

 

[easyphloem]

Good work on the removal, Mahk!


We will be doing something similar over the houses and the power lines. Actually, I am getting the local utility to clear a couple of the limbs over the primaries in the Red Oak. Every little bit helps.




We are scheduled to start next week, and I can't wait to see if we get our boom truck up that drive.

Call another AT operator...that dont look to bad. Hard to say not seeing it in person though. Those trees a MO-dead....be careful. Why the hell did they wait so long?

Good eyes Dan.

At this point the top and all of the other branches had been removed. After this piece was removed all that was left was the spar. I was in the 'grey' zone. Confident that enough of the weight had been removed that I could put my lanyard on the tree, but not so confident that I wanted to pull my climbing line out of the crane.

Looking at the pictures I dont see a need for dunnage. Is it to keep the back of the crane from bottoming out at thhe transition from road to driveway. I would think a truck crane could drive up that.

 

[easyphloem]

I am in Hartford, for the TCI Expo


The job is well on it's way, and the boom truck made it up the driveway with very little drama.


I am getting periodic updates, and will have photos when I get back.
