Options using an adjustable rope bridge.

[@Bluecollar711]

I love going back and looking at the older videos videos in which trained me 4 years ago to understand everything that was going on when I had nobody Richard Mumford thank you very much my brother

[@mvblitzyo]

Great ideas Richard I've often thought about the chest ascender, but didn't think it would assist in a limb this came down my climb line which has happen in the past lol it bonked me the head first ( PPE ) rt ya no injuries just a close my eyes n hang on ! It did hit my friction knot . And that was scary , at that moment I never thought that could happen. Oh well sharing the story helps out the new climber of what to look out for. Ps I really like my SAKA !

[@ipguyman108]

What kind of swivel pulley do you use? I just purchased a rock Exotica/Notch swivel pulley with 3 holes. The load rating was way below the load bearing weight that I expected for life support. I don't have it with me at this moment to state the "kn" rating . Thanks for all you do for all of us guys out here ..!

[@mtreeservices]

Great Video Richard! Been thinking about doing something like this with a rock exotica rope grab!

[@benoit.gerin-lajoie]

Nice gear !!!

[@SlammedBeretta]

Get a Petzl ring open or a petzl delta link and attach the Rollnlock on the other side of the rigging plate!

[@baloo32287]

so the device that is keeping you attacked to the rope is zip tied on? Oh wait, there are 2 zip ties. Should be good.

[@RichardMumford1]

Nice try but you're about 8 years late on that joke.

[@88mmFlaK]

Interesting configuration- my only concern would be the roll n lock causing stress riser scratches on the paw.

[@RichardMumford1]

Not a problem, it lays nicely, moves very little and it would take a lifetime to wear into the paw. Thanks for the input though. It is always good to have other eyes and brains looking things over.

Richard Mumford how do i search that rollnlock?

[@ipguyman108]

Love your videos and inovations. I however would NEVER TRUST "ZIP TIES" for life support. Zip ties are just plastic ridges using a tiny single PLASTIC detent. Am I wrong..?

[@RichardMumford1]

the zip ties do not serve a life support function

Kren Very good mister

[@gillettemarc3]

Always loved your vids Richard - thank you. I'm going to try out all these ideas. I have one other - your adjustable rope bridge could almost be taken a couple of steps further to make it also an adjustable lanyard in itself. Either by putting a small carabiner/connector where the termination knot is on your bridge plate, or by putting a biner/connector on the opposite (tail) end of your rope - then you could bring that tail end round a trunk/branch and (possibly) through another roll n lock/rope grab/adjuster connected back to the original plate the rope started from (to form a complete rope loop circling the branch/trunk - connection point to connection point). Or you could thread the tail of your bridge through a connector on your D ring, round the trunk, back to your opposite D ring - then possibly back to the starting rigging plate (though that is almost getting back to original lanyard rigging points - side D's). The only reason I'm thinking of this is because I use a flipline - when sometimes all I need is a rope lanyard. To minimise gear - if I'm making an adjustable rope bridge anyway - it might only be another couple of steps to make it into a rope lanyard. Just putting the idea out there for anyone to dismiss/modify. One possible need for this (apart from removing flipline from saddle when it is not needed) is when you are pruning small trees (and don't need flipline + climbing rope so much). Also if you are near uninsulated power lines (3 phase) - you want to minimise metal conducting (flipline) components on your person. At first I thought you wouldn't be able to connect your climbing line to your bridge while you are using the tail end of your bridge as a lanyard - but why shouldn't you? - It might take some jiggery pokery with rope grabs/stoppers to make both bridge and lanyard run to full potential - but it is possible. Maybe in the future lanyard and bridge will be one rope (and consequently even reduce the need for 2 pairs of full size D rings)? - Someone tell me I'm not going completely crazy... : ) Thanks Richard!

[@RichardMumford1]

gillettemarc3 The tail is there for a second bridge, why not a short lanyard as you suggest, I like the concept.....something to think about. Thanks

[@gillettemarc3]

Richard Mumford Effectively the bridge and the lanyard would be occasionally/alternatively sharing a certain length of the rope (the length just beyond the normal length of the bridge - before it enters a lanyard adjuster). I currently don't have the means to test this out. It may be my only claim to fame - but it could be called the 'Brailsford Loop' (my second name) - or maybe more appropriately the 'Bridge Lanyard Loop' Ha ha - Keep up the good work!

[@gillettemarc3]

gillettemarc3 Obviously - if you pull either the bridge or the lanyard to full possible extension on the rope - you will decrease the length of the bridge or lanyard on the opposite end of the rope; unless you applied some kind of 'stopper' or device/rope grab (that is small - quick apply/quick release) that can come up against either the lanyard adjuster or the ct roll n lock and temporary 'lock' the rope from being pulled from either end.

[@gillettemarc3]

Richard Mumford I was speaking to another Arborist today who has also viewed this video (and your other on the adjustable rope bridge) - he pointed out to me that it is possible that this ascender can sever your bridge if you shock load it. This is enough info for me that I will not use it in this way. What do you think? Should people be warned about this possibility? Thanks (he also really appreciates all your videos).

[@RichardMumford1]

gillettemarc3 I believe your friend is confusing this with the Wild Country Ropeman. What your friend described is not the case here.

[@RichardMumford1]

yes, I've seen it attached to the TM.

[@stephen1133]

Has anyone made this work with the TreeMotion harness? I'm pretty sure you could zip tie through the lower webbing slot. However I don't think the TreeMotion is rated very high structurally (I'll have to look at the paperwork again) so anything that might de-rate their rigging plates is probably a bad idea. edit: I just read the bridge is 15kN and the plates have no marking. I can't imagine the CT piece would change much. I think I'm going to test this idea on the TM with a small Ultra Tech, Amsteel, or Tech12 prusik. Slip knot behind the plate

[@treelimbjim]

I use this setup with a TreeMotion. The finish isn't as graceful as with a paw but I have no doubts about it. I believe I use three ties and inspect them well and frequently. Two to anchor to the CT to the ring plate and one additional to keep the becket aligned in case of some extreme event where the CT gets snagged. The optimal solution to keep the becket aligned would be a plastic coated maillon rapide--- and likely there's one of those shaped to hold the Rollnlock!

[@OldSloGuy]

What may not be obvious to everyone is that the rope bridge passes through the paw and then the roll-n-lock and finally there is the stopper knot if the roll-n-lock lets go. The zip ties only keep the roll-n-lock from flopping around when the bridge is slack. When it is loaded, the bridge pulls the roll-n-lock hard against the paw and the zip ties have nothing to do. There is nothing magic about a zip tie here, you could replace it with a shoelace pulled through with several wraps and tied off. Having the roll-n-lock loose is simply an unnecessary distraction that could be hazardous to the fingers..

[@RichardMumford1]

Thanks for re - stating that, I tried to make that clear starting at :37 and with a close up. The only problem I have with using a shoe lace is now i will drop my boot and hurt somebody. ;-)

[@Bluecollar711]

Richard Mumford You can’t drop your boot again that can only happen to you once do you still have that video? LOL LOL

[@patrickmiles5151]

The listing for the CT RollNLock at TreeStuff says "Not suitable as a lanyard or bridge adjuster." I'm assuming that's because it has a breaking strength of 20kN. Your thoughts on that warning? Suggestion for another adjuster that could work?

[@RichardMumford1]

I have a mechanical mind and not a marketing mind, I have no idea of the opinion. As far as the 20kN, being a shared load, 50% load on the other side of the bridge, seems this would be reasonable.

[@junglezilla74]

Richard, do you know if it is safe? I have the monkey beaver 2 point oh, I'm going to an adjustable bridge. I bought the adjustable bridge off of their site it comes with. A petzel ring open. Can I attach that straight to the rigging plate? Is that okay? Do you know? Thank you so much.

how much weight can 3 zip ties hold?

[@RichardMumford1]

I don't know. These are the black ones.

[@blackbird1234100]

they aren't holding weight though

[@johnmcgrath8111]

I was wondering the same and also wondering why anyone would even consider this. Shock load those zip ties and you will be sorry. Sure you still are connected on one side but the violent twist and uncontrolled spin that you will be forced into and then crashing into whatever happens to be in your path might make you wish that you just fell to the ground. Do you wonder why zip ties are not offered at arborist supplies? Are they rated? Not being a life safety connection is kind of a grey area in this instance but common sense comes into play. So yeah, the question... What are the odds of this happening, would you bet your life on it? The black ones? Are they rated? Richard's innovations and videos are great but this is straight up dangerous and makes him lose some credibility IMO.

[@aliray1165]

I bought this rook pulley and used it in some rigging but it’s not designed for that I guess

[@beckvitallys3573]

with all dew respect, I think those zip ties are not used correctly. Don't get me wrong and I don't mean to rain on your parade but they're still some how sporting your WHOLE!!! wheight plus your saddle. it's a great idea and the whole video it's very informative and you always have good vids but maybe using some kind of wide webbing or cordage or small diameter rope. If you see it from the viewers point of view, it looks like the paw it's being held by the zip ties alone. I still gave you a thumbs up. Take care.

[@JefAlanLong]

If those zip ties break the only difference will be the rope grab possibly flopping around when the bridge is not weighted. Even this is unlikely as the swivel pulley and unicender will certainly outweigh the grab and the tail of rope there. When the bridge is weighted absolutely nothing will happen, that grab is not going to be pulled through the rig plate. Worst case (extremely unlikely) the grab will slip a little, maybe as far as the stopper knot (3 feet?)
