Removals

[Mark Chisholm]

Well, I haven't been posting too many pics lately, so let's post a few.

This is a cottonwood I removed a few weeks ago.

It was a bit of a pain. I had two ropes on a bunch of it. Some was even roped off into the back yard.

The mess was supposed to stay, but some was just in our way. We chipped about 1/2.

Here's Juan flushing it off. Nice pile of wood, huh? /forum/images/graemlins/grin.gif

Here's a Silver maple we did yesterday afternoon. We started about 1:30. Here's a shot at 1:45.

Had lots of hollows and squirrels in it. Here's a shot at 1 hr later. (re-fuel)

Same shot, just close-up. It shows an area where a lead broke during rigging. This is before it broke of course. It broke right above the dead knub in the upper left lead (above where the rope is in the crotch). I used a redirect just above that knub and used it to swing pieces over the trailer. One hunk of wood swung past the leader and then crashed into it. That's when the top cracked out below the redirect. It was very dry in the center.

Luckily it was the third point of rigging so it never made it to the ground.

This was the most difficult lead to remove. It leaned verystrongly over the trailer. I decided to get some MA with the DWT setup.

Cranked up.

The felling cut.

The last hunk going into the truck. I lightened it up a lot because it was getting dark by now. It was 10 before 5:00.

This is my new favorite saw for this time of year. Heated handles! /forum/images/graemlins/santa.gif

Ya but, where do you sit?

 

[Colin]

Haha! Great shots!

Nice pictures Mark! Just a question though. On that leaner over the trailer what did you after that shot of it being cranked up. From the picture it looked as if it was almost cranked up as far as it could go and that you were still cutting. Did you just cut through it and pus it off or something? Great shots though. I like that big stump going into the truck.

Usually I'll keep cutting space out to make it easier to slide off. On this occasion I removed the shelf. I still had to cut a small hunk off before felling it, so I just took the floor out from under it. (check attachment)

I like the use of two pulleys.
I've seen some guys just doing regular rigging using two pulleys like that. What do you think of that ?

Great pics Mark. Nice job with the MA work.

Gareth,

Double whip tackle works nice, even for smaller stuff.

Since the load on the "ground rope" is halved, larger pieces can be handled without using a friction device. Once I had the systme perfected my crew figured that we picked up about 30-50% effeciency. Besides moving bigger loads we could get them on the ground and away much faster. Not having to de-rig after every cut saves lots of time. Pieces that would normally have to be lowered could now be lifted and moved laterally with the DWT.

You have to be aware of the load distribution of your anchors. In Mark's pics it sure looks like the anchor points would be adequate...don't you think?

Guess you couldnt flop any of the leads?

Hey thanks for posting that last picture Mark to show how that worked out. I get it now. I didn't really think of that. But now that I do that was a good way of doing that. Thanks. Keep up the good work and the pictures. I like seeing them.

DWT! Double whip tackle, I learn something new every day /forum/images/graemlins/bounce.gif
