Well well it's 2020 it's still a valuable information thank you

Thanks a lot for the great video! I am sure it will significantly help our community to slack safer! ;)

Very professional and convincing. Thank you for the video :)

Thanks for the valuable information!

Thanks for sharing!

Thanks guys! It helps a lot.

Did not see that coming! Very interesting.

That "pear-shaped" carabiner is actually an "offset-D" carabiner which is designed to be loaded along the axis of the back bar. If you actually used a pear shaped carabiner, which incidentally is pear shaped and ,like a pear, is symetrical in design, you would find that the breaking force for the tri-loading would be significantly higher. Obviously, if you tri-load an offset-D carabiner there is an undue amount of force along the axis of the gate, which it was never designed to accommodate.

pura vida slackline😎👍

Watching this in 2021 before taking my climbing/abseiling/high ropes guiding exam

thank you so muuuch

2019-3-29 首次阅览 拍得很好，继续加油

Can you please perform the same or similar tests using stainless steel or aluminum carabiners?

thanks

very good~~

I have been thinking about a way to solve this problem for a while now in climbing anchors and i think i may have come up with something. Join the two ends of the webbing with a butterfly bend, no crossloading of the biner and the knot is known for being strong on all sides.

Hey :) i'm watching your videos for 2 years now and really enjoy them all. Keep up your nice work! ;) A few weeks ago i bought my first 100m Slackline and i wanted to know if it is possible to connect 2 roundslings with an anchor sting or another knot, if the roundsling is too short for a tree... I did it today... but i wasn't really sure if its save enough. Greetings from Germany :)

очень полезно! пасибо большое!!

would be interesting to see the test repeated with the large end of the HMS pointing at the wider side of the rigging, as it is designed for?

Great. I just bought 10 ovals on Amazon this morning at a good price. It was a choice between 5 pear or 10 oval with a few dollars difference.

What about a small rigging plate for load distribution? Like a Petzl Paw S? That'd make a ton of sense in my mind

...or just don't tri-load your carabiners. Pretty easy to avoid.

mind blow

In the market, there are available carabiner designed to work loaded in three directions.

Is the weakening of the carabiners after repetitive loading really so big of an issue with steel biners?

Thats why my roadeavour has a shape like that.

Just use two biners, one for each end of the sling, clip them into a welded ring, then another biner into the ring.....

I would question the shape decision of the pear=shape carabiner if the oval one is basically stronger.

I see petzl give a "warning" about that, why? what a point....

Is there any reason why you can't use a girth hitch to avoid the 45 degree angle when tri loading?

This is good data

I love oval shapes

Even though the gate broke it was still holding load... how % more load until absolute failure? Loading biener in correct orientation.

As a conclusion I would say the pear shaped one is always stronger. You just have to use it upside down.

Unpredictable outcome

Someone read the manual that says if combining multiple anchor points combine them to the small end to eliminate Cross loading 🤦‍♂️ I am glad to finally be able to say some numbers when people insist on doing this wrong.... Don't like that it's still 23kN

you mean shape i think. i think theres a translation error.

Is that D carabiner, not pear?

Carabiner in your vid is d-shaped, not pear shaped. Pear shaped are basically hms. Easy to check. Otherwise great job man! :-)

If you divide the wide side, it will be weak.

You should continue the test all the way until the rope actually detaches. The pear shaped carabiner was still holding on when you aborted.

Definitely should never tri load your carabiners, if possible. But also I wanted to point out that your test is flawed. Your testing the 2 biners unequally. The oval shaped one you use a webbing sling for most of the testing. Vs. The pear shaped you use a those steel links. That's why you see the breaking point significantly weaker. The webbing sling spreads out the load on the multiple points of contact. Think of how a girth hitch vs. Basket hitch does the same thing.

Your ovals were all "upside down", the pear shaped was only "upside down" for the very last take. Youre creating conclusions which don't exist. What you actually showed: pear upside down: 45Kn pear full: 55Kn oval upside down: 30Kn oval straight: 30Kn Extra result: pear other way up: 30Kn...
