does it work ok on the 11.7mm double braids that are common in tree work?

 

I think it's only supposed to go up to 11mm ropes but I have used it with 13mm xtc and apart from being a bit stiff at the top of the descent it works fine. I guess the rope size limit is to stop wear on the sides of the casing so if you do this a lot then you should inspect it often. I use mine only for ascent using the yoyo and that's with an 11.7 mm which works perfectly well. Also for my emergency descent while chogging down a pole so it basically never gets used and just sits on the rope waiting for that moment I hope will never come.

Agree that in say the competition world it doesn't stand up to the triple-action standard but in the real world, and bear in mind i use mine for descent only - not work positioning - it is fine.true true bro but its in the catalouge for work positioning

Yeah but isn't it designed and advertised for industrial rope access work? I was under the impression that they always worked with two separate rope systems anyhoo?

 

While we are on the topic, what about toothed ascenders like the croll and hand ascenders. They only require two movements to open the cam, same as the rig?

thats a good point bro

My IRATA log book has over 2000 hours in it spent on a rig, never once did the gate open. ropes occasionally rubbed over it with no adverse effects.

 

crolls and jammers are only considered a point of contact if weighted.

The ISC hand ascender has a cam lock so it can not come of the rope.

The Croll and Ascension are desigined to be used as a unit, not individually. To disengage completely from the system and escape the rope requires the removal of both devices, 4 movements in total.

No not at all. It is designed and advertised as a belaying device for rock climbers only. People do use them in rope access because they are handy but if mr IRATA came along he would'nt be very impressed!

 

The toothed ascenders are impossible to open when loaded. There is a sequence to getting out of them.

 

Rope access has a 2 line system, one is a back up line which you are connected to and the other is your working line which is loaded.

Thats interesting, my local arb supplier here in Australia stocks petzl gear - but is only allowed to stock gear which is designed for commercial use - He doesn't sell the grigri as that is recreational gear but does stock the rig and ID.

 

Good point about the fact that the chest ascender is designed to be uded in conjunction with a hand ascender hence the four movements to disconnect the line
