Unicender ultimate load value?

[warddc]

Does anyone know if the Unicender has a published ultimate load value? I didnt find it in the documentation or on the web anywhere?

I don't think that would be a relevant number since the device slips way before it would ever break

Wouldn't that be the case with the Rope Runner as well? However they publish an ulitmate load value.

The UNICENDER was not designed to catch a fall and must NOT be shock loaded. Keep slack out of your system at all times to avoid the possibility of shock loading.
Do not use on icy ropes. Do not use on twist constructed rope. Use braided ropes only of the correct diameter. Remember your climbing system is only as strong as its weakest link. Check all equipment before going aloft.

The UNICENDER is intended for one user.
Do not load it with more than one person.
Do not lend it to someone else.

Since it's intended for one user, I'm guessing 250 lbs. is the max load on the device.

Ansi considers a single person load to be 310 lbs

Fwiw I have never heard of a uni failing

This is the video that comes to mind for me as well. I watched this vid before I purchased my Uni, and it made me feel better about the device's integrity. At least it grabs on a slacked fall!

Realistically, aren't all mechanical hitches in the same boat? Just me thinking out loud, but I expect the rope runner, BDB, zigzag, etc to behave the same way? Have any of those devices been drop tested like this yet?

I think you are correct I remember hearing that at least the bdb and roperunner slip under heavy loads.

Yeah... so does the ZZ... and some of the descenders like the ISC D4/D5 and Petzle I'D also do that...

Seems to be the best behavior for most scenarios. Unless, of course, it slides 10 feet and there's a pit full of hungry alligators 9 feet below you.
