TreeMotion bridge break test and more.

Richard, did you inspect the tree motion after testing? Any damage to webbing or stitching?

Aside, I'm happy to see the bridge pull test. With all the talk of bend radius, my greatest concern has been the bend at the d's. Suspicion confirmed.

Thanks for your work and dedication in this industry, Richard.
 
I was surprised to see several of the double overhand knots seemed to be rolling out.
Granted that didn't seem to happen until the failure was imminent, and the tensile forces were very high.
Obviously, that knot should be tight-tight-tight before using it as the bridge.

I now know 4 very-very good climbers that have had /or were exposed to, figure-8 stopper knots roll out. (not related to use as bridge)

Therefore my go-to stopper knot, for quite sometime, has been a double overhand.

I know of one very good climber that has used a triple overhand stopper knot.

Just comments .....................

It would be interesting if the MCRS bridge would test out any differently if tested as it comes on the harness. That is with anchor bends tied onto fat rings. I was impressed how well both bridges did on the DMM hardware as the stopper knots do get loaded sideways to the plate making that first bend relatively sharp.

I did load and release these with about 200 pounds each before I did the pull test.

Yes, no torn stitching or stretching on the webbing and no defamation on the forward rings. Impressive.
 
Well it was just a good observation on your part and I thought I would point that out, I'm not sure if I made a big deal of it in the video or even mentioned it, it's a good thing to bring up.

The bridge from New Tribe is possibly supposed to be Platinum. My Onyx originally came with the one you show, @yoyoman. I didn't want to press New Tribe about the difference, so I just replaced my bridge with Platinum. Does anyone know why they had this non-Platinum rope on their harnesses, and do you have more info on that particular rope bridge's history?
 
Just finished the video. NICE job! this is the most valuable video you have made (to me at least). Question on the stock TM bridge: Did the core fail or pull out of the cover? It appears that the length of the core either stretched, pulled out, or the cover bunched up a lot!
 
The tests are confidence building. Nice to see scuffed up gear still retain so much strength.

What is the shortest piece of rope or webbing that you need for pulling?

I've got lots of used soft and hard gear that could be broken We talked about breaking a chunk of that three strand Manila Green Stripe I had at Jambo in St. Louis. Lots of very old Arborplex that has been on the shelf for years too

Thanks for taking the time to test and share
