Three days of rigging

[tod_k]

Had to remove this twin stem Elm. 80" dbh

 

[tod_k]

We used 3 rigging points and two GRCS's to lift just about every cut.

 

[tod_k]

Lift.

 

[tod_k]

And away

 

[tod_k]

This piece of wood was still 45' up the tree.

 

[tod_k]

The bigger wood was lifted into a primary rigging point and then drifted into a secondary rigging point to a clear lz.

Last cut on one of the stems.

That tree took 2 days to rig. This tree was the next day

Good job Tod, thanks for posting the pictures.
How far did you have to drag that tree to get it out onto the street?

Awesome pics and work as usual, Tod. What a monster elm!! I always love the challenge of big spreading trees, but we have less of them in the PNW than back east.

A question for ya: Are you using UHMWPE lines yet? I've found them to be indispensable for lifting and speed line applications, due to their extemely high strength to size ratio. Are you using 5/8th line on the GRCS? Presently I don't have any, just our 9/16th, which is the optimum size for the GRCS, due to its too small capstan for our 3/4. So I use the Hobbs for its larger capstan. I think the 13000 tensile 9/16th is too small for shock loading applications like trunk lowering heavy wood. I'm sure the 5/8th would allow 4 raps on the GRCS, which should be adequate for shock loading. But our Puget Sound Ropes 19000 lb tensile fully static 9/16th is awesome for non shock loading work.

As well, I plan on putting some spectra on the chipper winch, and for that, unjacketed hollow braid should be OK. I was thinking of putting a jacket on the last 10 feet of line...

That sounds cool to me Roger. Interesting idea.

It was a long way to the street. At least we could use the driveway the whole way. The brush was rigged with a 9/16" double braid and the wood was 5/8". I have not tried an exotic fiber rope for any rigging ropes just slings. WHile rigging with multiple rigging point and lifting sometimes a hinge might break or the cut just might not go as planned so I prefer a rope with a little forgiveness. The broken cotton wood was removed with our crane and the utilities 75' bucket.

 

[tod_k]

Then once the contact points were eliminated we lowered the entire truck with rope and crane.

 

[Mark Chisholm]

A strong exotic fiber rope would have been good for the trunk hold, then lower. It is great to have for those types of jobs.

That's great old school hardcore treework.

Where did you get the shirts made by the way?

The Revenge of GlenS

Though GlenS took (and dished) lots of stuff about pix file size; i L-earned something.

Smallest pic file size was 137k, 3rd smallest was 340k; totalling 5.87meg.
Shrunk, manipulated, compressed all 11 + viewer + hot links down to ~180k (Revenge of Glen)
for whole package with small loss in definition to pix.
Goes to each pic automatically, or can click slider below to view specific pic. Will werk FullPage, pix (raster graphics) having better definition in smaller window though. Rest is vector graphics, not so much quality change with window size.

For the cottonwood an exotic rope would have been a good application. Our uniforms were made by a uniform company. Cool slide show Ken.

Re: The Revenge of GlenS

Tuesday we started this 62" American Elm. Half is over a primary we got a 5 hour line kill to clear it to about 8', a large limb around 28" was around 1' from it.

Re: The Revenge of GlenS

This is the trunk and mechnaics of the heated driveway, it's around 100' long.

Re: The Revenge of GlenS

We covered the landing zone with plywood, the client wanted zero impact. We also got our Kubota to fit through a garage port. God bless the Kubota.
