Trivect Rigging Vid

first let me say, very nice job and great video.

Then, don't get too bent out of shape about my conversation here.

Three ropes gives an awesome amount of control. I don't know if dyneema and the calculations were needed, especially by skilled people as yourself. But I suppose if they did not slow you down much, great, why not.

Almost seemed like overkill, that's all. But overkill is much better than not being prepared.

Keep up the great work and hope to see more videos.

So how were the rigging points installed.....from the ground, or did the three trees have to be climbed?

That is the time consuming part.

We have a permanent access system in place to help reduce some of the time spent setting lines.

Aside from the height (first limb usually isn't until 150 - 170'), firing throwbags and crossbows around runs the risk of damaging the statues, in the highly likely event we miss our target.

There are adjacent trees, outside the protection zone we can fire lines into. We ascend to the top, throw a line across into the next canopy.
Transfer to that tree, and repeat.

To get to where we work, we probably transfer 10 times or so.
Once the string line is in place, we just leave it there for future access.
 
Haha don't worry Gord, I didn't think you sounded negative at all. My dry humour doesn't translate into text well :)

Yeah software project of mine... Wish I had a little more time to make it nice.

Hope your keeping well anyhow.
DiNG on your 1000th post too.

Thanks everyone for your compliments and questions.
I'm super conscious of me spamming threads with waves of responses, but I appreciate you guys sharing your thoughts on the video and the job. Makes doing it worthwhile.
 
Yep, 5 hours is impressive. I think the whole thing is just dead sexy. I loved how the pieces stayed static as they parted. World class, that's all i can say.

I do some rigging like that but never on that scale and never with that measure of control.

I agree, Sherbrooke has consistently demonstrated the highest level of competency I've ever seen on video.
 
Given the conditions you had to work with, that was very impressive. How long did it take to develop the software? How often do you use it in your everyday work?
 
Yeah, you guys certainly rock. I watch that Tahune day 3 vid religiously. I've been telling the guys at the shop that "Sherbrooke has done it again!" Thanks for sharing Angus. Waiting anxiously for more.
 
Thanks :)

The software only took a few hours to write, but deriving the formula took a while - even though I wrote it, I don't have a strong background in vector mathematics.
In the end I used perverted trigonometry which evidently got the job done.

We don't use it in our everyday work at all.

It's interesting - now we've got it, it has changed the way I look at doing jobs. There are a few configurations that I won't discuss until I have video evidence, that could be advantageous to everyday use.

The system was developed specifically for works that we couldn't apply "opposing pendulums" rigging.

On this job, we couldn't safely work on the tree unless our rescue and access line were free of all rigging. This was not possible for a whole bunch of reasons. This was a big driver to produce the three rope system.

If we used two lines, the load would be displaced, shock loading everything, very high likelihood of dead wood falling. The dead wood has a hell of a run up, so it doesn't need to be big, or a direct hit to do catastrophic damage.

The tree itself had two bee-hives, and the top 40ft was too sketchy to climb and rig in a dynamic system (it would just fall apart). That is why we took 80ft in one hit, statically.

Ironically, the under story doesn't allow video viewers to see what we are dodging - but it shows what we can see; Nothing!
