three dimensional speedlining

[Paul knight glos]

Not my video sorry. Posted on behalf of my friend who is the designer/ climber and editor.

 

I've used the device but he is better placed to talk about the finer details of it.

 

The device does help to what would of previously been tricky tree removals.

I want to know more. Please explain how it all works as just when I thought I'd worked it out I doubted myself again.

I with you there!

 

Dreadful vid!!

 

No, wait a minute, didn't enjoy it because it was all going too fast and I couldn't get to grips with it.....

 

I need a diagram!

 

The work is awesome, I only didn't "like" it because i didn't understand it....

 

Very impressive!!!

Great video. Looks like a very compact English Reeve. Great idea and simplified solution that can be a bit complicated. Looking forward to seeing more of this!👍🏻

I asked on the YouTube video itself and the climber replied to me so head on there if you want a good explanation, but I can give you the gist of it.

 

Top line is a static speedline and the trolley(blue thing) travels along that line.

 

The other line you see that has the DMM pulley block on is what controls the lift and the drop of the DMM pulley. It's tied off on the host tree and then goes through what I'm guessing is a pulley and down to a hoisting bollard(GCRS Hobbs etc.). I think scenario they have a power unit that used the hoisting capability to lift the pieces and then just letting off the line lowers it

 

The last piece is the green climbing line connected to the rear end of the trolley as a braking line to control the movement along your static top line. He said ideally would be controlled by another groundy but due to people constraints he took charge of it in the tree

That makes sense now. I was even more gob smacked when it said 3 people.

Great video & setup 👍, you can see in the pic the basic principle..

Nice video- the carriage functions similar to a skyline one. Interesting concept

That block certainly neatens up an English reeve, I do love a job that requires one. Setting up and operating one makes a great training exercise, especially on a smart winch, students can practice flipping between the track reeve and control lines and all the while having to communicate far more than during conventional rigging techniques.

Cool vid... well smart! And a very nifty crew working that job.
