Great

It could have been done with out the hub. We did that job 6 years ago. Having the hub just made it safer, faster and easier. The climbers repelled on grigri's and walked up the slope hith a hand held grab backed up with a seperate prusik.

The width of the slopes were about 20 meteres. The hub sat right in the middle. We had 9 of these sections to do. A nice feature was not having to use any connecting links. Plus the system was easily repeatable. We also never had to untie and re-rig. We just through the hole thing in a large wheeled duffle bag. We could tear down one slope and rig another in about one half hour.

The horizontal ropes are htp static lines. Each on is acting as a twin rope anchored to a porta wrap and tensioned with a 5 to1 mechanical advantage. Then backed up with seperate prusiked organized with a hitch climber.

I had a chance to use a large hub this summer. We had a vista prunning ( reduction for a view) job that was on a very steep and long slope about 40 meters long. We needed to be secured on the slope so we created a fixed highline for the crew to decend and cut on the slope and also to get to the trees.

He is very good. Do a youtube search of Ryan Leech and Jeff Lenosky, great stuff . Same style

Here's a pic of our building plus a bit of the yard.

I've been a bit busy lately. I post one soon.

I'll try. Hopin to pick up a few tricks that may not have made it over the pond. Thanks for the welcome.

Forgot to describe it. A munter backed up by prusik for autoblocking. It very easy to lower a climber. Plus it is familar by arbors and rescue personel.

I like this anchor.
