Thanks Fred for your Braveness. That's pretty interesting that it was almost 6000 pounds To break that rope and that wasn't even the weak spot. Thanks for taking the time to show us the quality of the equipment.

Thanks August and crew! Really thankful for good information!

Thanks for that and thanks for all the stuff you are always showing us as well appreciated

Thanks for the info. Awesome that you are doing these test.

Very neat, love the info. Keep the videos coming.

Cool video. Testing above & beyond the limits is good thing. 👍😎💪

Great job, I love the attention to detail yall put into every product. The fact that it was made with care and also quality tested, makes me want to buy more. I know it's not just thrown together in some factory by a person who does not care and hates their job anyway. Haha. Yall stay safe. Catch you on the next one.

Love the TESTS!!

That's awesome that you were so thorough. Appreciate it as a guy who uses and adjustable bridge.

Very interesting. Thanks for sharing.

Always like these test Video's Nice record to have as thing move forward ! Fred looks great Joe

dude I am in process of making adjustable bridge out of one and was wandering just this! God bless ya August! Needed this!

after looking into your videos and gear and noticing the adjustable bridge line i went and tied a prusik on my rope and thats how i adjust mine and it works great for me!

Fascinating. Thanks for the viddy.

Really like the time put into the science of what we do that makes us the user feel even better about the safety of a great engineered time n true tools That make our work possible and comfortable. Joe from California

Great test!

Thanks for doing this and pushing the envelope by proving what is realistic

The problem is not a new adjuster, but one that has some wear on it. The adjuster's cam has rounded bumps that after a little wear are no longer round but flat topped with newly sharpened edges. Under these conditions, slipping over the cam's bumps is no longer possible. without cutting the sheath. The original Rescuecender slipped at about 1300 lbs which translates into a 6.5 G shock which is what fighter pilots experience in a dog fight. Again assuming a 200 lb load, a 6000+ lb shock represents a 30 g shock to the harness and is guaranteed to be non survivable. In this situation, you are entirely dependent on the elasticity in the climbing line. Your test has one fault, the hoisting rope is not allowed to remain in the system during the drop. Think about using a Porty attached to the crossbar with a shackle. This takes the knots out of the attach point termination. The many turns on the Porty keeps the stress concentrations low.at the anchor. The stretch from tightening the wraps is insignificant compared to the elasticity in the hoisting rope. Of course, I am thinking of rock climbing which is truly hard anchors with stretchy rope. There is a reason arborists don't ascend on stretchy rope. Successfully arresting a fall is very dependent on the length and elasticity of the rope in the climbing system.

It is great that you care about the safety of your test dummy, with the backup; Does he have a name yet? So he does have a name, that's great. Love to watch your work.

Love these video's too !!! It's always amazing how the rule makers make rules but they don't have a break text machine or a Fred. But they still make the rules. Can't wait to get a new MB Saddle ❤❤

Thank you August , that was very informative... I personally would trust the adjustable bridge set up... I have been wanting to get in contact with you to order my next harness, I would like to duplicate the set up that you use . Thanks again....

Knowledge ✊

I've seen the Mumford Roll 'n Lock adjustable bridge videos - haven't done either yet. Regardless, great to see actual testing!

Good stuff ! But now I’m curious if an Ashley stopper knot would be more stubborn than that one.

Nice to meet "drop dead Fred". That is a nice test set up. The pull break was really an eye opener, to support knots weakening ropes, I am a believer now. Wow. Cool test. I suppose a jell skellitul, dummy would be more life like but your test would fail sooner as a rigid dummy made of wood with weights so your erroring on the side of safety or exceeding which supports your argument. I have always used fixed lines but I would try an adjustable bridge now, the one you tested, the adjustable cam seemed to hold together well, I like your idea of red paint or engrave or stamp.. 'for rigging only', nonlifesupport. Good job you guys, I like it...ulaut.. Thank you.

Personally I like to run bridge rope (same Samson .5" you guys are using) through a hole in the rigging paw and use a CT roll,lock or a Kong duck if nothing else...don't even ask how I keep the plates together...but just works so well and is truly fail safe with a dead end knot in the end.. I will be buying a monley beaver saddle as soon as my Buckingham needs to be retired..you're the best August, and samuari Joe!! Thanks for all you do

Old school climbing at the end, nice!!

Dang Skippy I cannot believe how violent that fall was it would be interesting to see with a force gauge what kind of forces did that big dummy put on that attachment point when it fell twice at that last height love the video please continue

Idk why manufacturers don’t publish this kind of stuff. Awesome job busting those gear myths!!

I have been running this type of adjustable bridge and I trust it completely 💪🤙 Stay safe stay healthy

Nice testing!

The scariest part was climbing that orchard ladder.

I feel smarter after watching this. 🪓🪓🪓🪓🪓. Thanks for sharing the experience folks.

Drop Dead Fred is like a Groundhog Day horse thief.

I have very strong cordage for hitches that r a tight eye 2 eye variety that must be strong even though they have superficial wear & tear on them. That test just gave me more confidence in my gear. Thanks Fred. Oh by the way Fred, I have u on the schedule to work Labor Day in a few weeks 😊 , lol ...ha haha 😆.

Good test guys very informative and interesting,

Was that regulation climbing equipment you was using climbing that tree at the end of the video lol

That was a very interesting video.👍

Very good

Nice vid I wonder how the art position 2 would do on that test have a good day

A proper designed cam rope grab should slip before it parts the line, it would be interesting to see the paw to ring setup put into the break tester. And then you did so! 😆❤️❤️❤️

Was looking at the bridge setup as a idea 💡. Think I will run the tail end of the 7ft adjustable bridge threw the rigging paw then tie stopper knot seems like it would function same with a little backup redundancy???

Just for S&Gs, you should break test a new piece of rope with TWO of those adjusters, as the weak spot created on the rope seemed to be the knot through the static anchor point on the non-adjuster side. Cheers from Tokyo!

It will work good enough for me to keep my feet on the ground. Thanks guys for what you do, I’m not afraid of heights when I’m in a elevator.

Mr. Hunicke, have not written in before. just been hanging out watching your stuff. back in my day we didnt have all the fancy climbing gear you boys have today. we did all the rope tricks but without the fancy other gear. for climbing gear, all i ever had was a good set of spurs, a simple "D" ring belt and it was onward and upwards. i dont climb much anymore. still do a lot of ground work falling. thats basically what i am, an old faller. 70 years old now but still at it. i watch how your crew works. back in the day, if anyone had a crew like you have, or appear to have on screen, well they was something really special. them boys would have been top dollar on any crew and could have set their own incomes. another thing, dont let anyone distract you from the Lord Jesus. there is only one way and its the Lords way. i been around a lot of stuff, had lots of stuff happen working and the only reason am still here....God has a plan and no one knows that plan until we get to meet the boss himself and he shows us what we did or didnt do right. right? right. having said all that, i would like to have a moment of your personal time off this net. something i have seen that needs to be addressed and no in a public manner. no what i mean? thanks for your time August.......Jim way up in dah UP of MI.

I ran a ct flip line grab and a petzl ring just like that for about a year on the monkey beaver 1.0! Now run a ct roll n lock on the outside of the tri knuckle. I think it’s the most sleek setup with a nice safety net

Good Morning August. Good tests. There at the end of the video those flamingoes have nerves of steel, all that work going on and they just lay there like no big deal....

I am sure glad Fred is 10 pounds heavier than I! It means I'm even safer than he, and if, Lord willing , I ever get over there to visit I won't be eyed as a possible replacement for Fred, thankfully also not having the required weight necessary to properly test the stuff! As I watched the drop tests and the damage to the rope i was hoping that you would pull test it after. I have a 25' lanyard made of the same stuff and very interesting that it did not fail at the damaged point! Great test and great rope :{)

U guys need more videos on drop testing and breaking more equipment.. and maby even drops outa trees to see how much a tree flexes or straight up forces on tie in points

Don't see any problems using the adjustable bridge. Take care and have a blessed weekend and I'll see you on your next video

I said "yes "before I even watched it. Cause you use it as a lanyard adjuster wtf is the difference. People like to science fuk thing to feel important. Awesome videos. Love u guys. Bsafe

Sooo, fun fact, Petzl do a variant of the Petzl Adjust personal anchor called the Petzl Sequoia Adjustable Bridge, which connects to your harness with 2 Ring Open's...... it uses use the same adjustment point as the Petzl Adjust. I actually own one of the Adjusts and there are a couple of spots that kinda make me think of a rope guillotine 🤔 I'd love to see the 2 different ways to make the bridge using the 2 different setups to see which gets the most damage, how many falls they survive, any other fun things that you would like to try 😁 Thanks 👍👍👍👍👍👍

Nice test 👌

It's interesting how you can physically weaken something, and then put it to a Insane destruction test, and it then surprisingly fails Not at the weakened area... LOVE THAT

Yes we sure are! The equipment we use has such a large safety margin and what a relief. It’s great to see you testing it to failure. I was shocked when I read that the DMM mini swivel I suspend myself from only has a 3kn WLL.. Have you ever tried to pull one of those apart?? Thanks for being awesome!!

This is also a drop onto a static line. In an in tree situation like this, one would hopefully be dropping into their life support line. This will add many more factors of shock load reduction depending on what type of line they are using, how far they are from their tie in point and what configuration their line is in (SRS vs. MRS, canopy anchor vs. Basel anchor etc.). That all said, this is a good test as is tests worst case scenario.

Well, I trust that Micrograb as a flipline adjuster, so I can't see any reason why it wouldn't work equally as good as a bridge adjuster. Personally, I run two short bridges on my harness, and I haven't really felt the need for a really long one yet. Maybe that will change with more experience on my part. In what situations would a really long bridge be beneficial? Thanks for the practical testing, always good to see that. Really interesting where it finally broke, I was not expecting that at all. Keep up the great work.

I forget who did it, I think it was climbing innovations, used a rollnlock on backside of paw for an adjuster, n just had 550cord or ziptie to hold rollnlock to paw. Best setup I've seen IMO

Years ago I used to use a petzl shunt similarly, it used to flatten the rope but the big danger with using the shunt was if you fell and slammed the tree the shunt could open up. Is there redundancy in this? Apart from the stopper knot. It would be good to see if it could withstand the forces of a short factor of 2 fall

I would like to see this tested on an old bridge that’s been in the field for a year or so.

Not only did I interrupt the drop test I interrupted a video 🤦‍♂️🤦‍♂️🤦‍♂️😂 cool video tho!!

Can we break test the rope from the test to se whats left for strength? Would be interesting Spoke too soon lol

I gatta get micro grub now. LoL

do you sell flip lines on Monkeybeaver? if not any recommendations? thanks for all you do for the arborist/tree community, August.

I NEED that ring and adjuster lol Think of the starving arborists!

Do you think the art position would be good for that ?

When are the new 2.0 beaver saddles gonna be ready

Poor Fred 🤣😂🤣

I'm far from an expert, (I used to climb rock back in the 90's, and have a bit of industrial climbing experience), but wouldn't a normal length of rope (especially DRT) or a standard "rip" style arrestor, all but eliminate any 'crimp' at the camlock adjustor device anyway? I understand you are "worst case" testing here, but it seems way above and beyond any real life situation. I like this kind of content, thanks for letting us in on the inner workings of your design and testing. FWIW - I would climb anywhere with that bridge setup and have no concerns.

Where did you get that three ring quick release? I’ve been trying to get one for my own testing stuff. I’m just up in Albany Oregon is there any place local that sells those?

Drop Dead Fred: Love it

Interesting how the failure occurred at the location least expected.Fred lives though.

Wouldn’t a Prusik or Schwabisch hitch be a better option that the Petzl grab? Wouldn’t damage the core and the failure mode would actually show melting damage to the outer portion.

I'd like to thank your drop test dummy for his excellent work. Does he have a name? Woody? Thanks for your dedication to excellence as well...

Would it be safe and practical to use a prussic instead of the mechanical device? Just wondering if that low tech (& low budget) solution would work as well.

While I am sure it could be used I weigh 130 pounds. My issues or concern would more or less be if it accidently adjusted mid cut for some reason? But thinking about it in retrospective I agree its hogwash. I have never had an ajustable flip line loosen on me.

but how many have fall a meter as a arborist, you always tighten up loose rep ( climbing rope )

Thanks for sharing the test. I never really understood the advantage of an adjustable bridge, but I guess some people like the extra gear

Super good enough. That's what that high line guy says on KZfaq. It will slip before it breaks. I'm 2min in.

Only thing is while climbing in thro stuff can push the release without knowing. But yer seems fine to me.

Have you guys seen the climbing technology’s roll n lock style rope bridge? The great thing about that setup is, if the roll n lock failed, it would still be stopped by the paw

August thanks to you sir and I'm not gay in anyway, but I'm a better climber a better arborist and a safer worker and I love you for it bro thank you

I like it. I would use it. Might do this to my monkey beaver saddle

Still not one to run adjustable bridges, just don’t really see a point. But awesome little video for proof of concept. I’m out here $50k in production on the 2.0 in a week and half… absolutely incredible saddle. Such subtle, yet drastic changes. Took a min to get it adjusted as I like, but now that it is. Oh my goodness friend, incredibly comfortable. Did 1600’ of cleans in a day, left the job with just sore knees back felt great! Highly recommend everyone upgrade as soon as possible.

ok so in theroy couldnt you use a prusick or some other non mechanical rope grab to avoid the crimping and fraying

I have trusted my life with far less for far greater peril then that. In the near future equipment will reach the feed back loop where more accidents will happen because people will take no responsibility and expect the gear to have common sense and think for them.

I need that monkey beaver harness. My rib cage can’t handle a whole lot more abuse

What's the best way to use the micrograb with the existing rigplate rather than adding that petzl ring?

Not sure how your rig and load cell are set up so this comment not be applicable but if you are applying 6k pounds to the shackle that the bridge is running through technically you are only tensioning the bridge to about 3k pounds. Not saying it’s good or bad, just want everyone on the same page. Nice to see behind the scenes a little- great video as always.

U can use the CT rolling lock like Richard Mumford does he climbs on the onyx newtribe very simaler to monkey beaver just deferent rigging paws slightly and plain jane..sad new tribe went out of business aswell...think I'll order one for my 2.0 beavers..I have everything but that petzl grab.

Don't be a dummy where your belt

Hey man!

The bridge didn't even break. It did let the rope slip through it before it stopped at the knot... I'm curious how many pounds of pull it was at when the rope slipped through the bridge.

For Science ! 👍

So just like a motorcycle helmet, if you take a hard fall, swap out the rope and carry on 😎🤙

#getaugustto200k

Hey August how are you my friend just curious is there any release date yet on the monkey Beaver 2.0 saddle harnessed thank you

Can’t you just run a secondary bridge through your ring that is the same max length as the adjustable?

Can you do a break test on the petzl ring

Did you make Fred?
