just got a new HRC eye to eye the other day, grizzly spliced. used it for a few climbs, then upon my next pre climb inspection i noticed the core is pulling threw the cover for some reason, any ideas why that would happen??

could the core be a different length then the cover and after some use it found its way out, i hope they will give me a new one.

I have had the same problem with soft heat (a variant of beeline).
See this thread: http://www.treebuzz.com/forum/showflat.p...rt=2#Post216597

I have just received some new soft heat from the store.

That is very typical for HRC. I have seen it many times, in a co- workers HRC. Usually after a month or so, not after a few climbs. Something to look into as to why it hemmoraged (sp) so quickly
 
There's another thread on this. Apparently NE changed the jacket weave or something and this started happening. I've spliced a lot of HRC tails and only my last two have this issue.

Yup. Did you have a problem with the stuff with a gray/black core?

ok that is a good picture I have no idea why a grizzly splice would do that...sherrill is the only one to do this splice right?

Nope, the "grizzly" is sherril's name for their stitched eyes. Other companies and rope manufacturers offer stitched eyes.

DON'T USE IT.
Call the supplier, they should replace it.
It's herniating and they (cover/core) won't share the load like it's designed to.
 
Yeah, that is a bit normal (unfortunately) for that newer version of HRC. They added material to the core so that it would still hold a 5000# rating even after the stitched eyes were included. That makes the material want to escape the cover.

There is a new version where the cover has more material now to help keep that from happening. It might be available already? If not, it will be replacing all supplies soon.

Do you know if it increases the overall diameter? I've been hoping for a slightly fatter version of the stuff.
 
A collegue of mine had 2 hrc in a row hemmorage just like that within the first 5 climbs, couldn't recall if they wre grizzly or hand splice. Either way after this thread and personally witnessing that same problem, I no longer trust that stuff, think I might just stick to my bee line.
 
Unfortunately, B line does it too. Many ropes will herniate depending on the cover and the core. One thing that is very good about the high-tech ropes is that fact that the core alone is usually stronger than the core and cover of a poly prusik. Safety is not a major concern in that example.

Glad to hear that!
I've been climbing on it for more than a year. I am pretty concerned with my prusik cord's, so I normally replace them pretty fast. It hasn't seemed like a major problem, but I am glad that I have got some of the "new version" from my dealer. The old stuff have passed gear inspection at comps three times too.

Have a fantastic weekend!

No one should put up with herniating ropes! Since it happens both to HRC and to Bee-Line, it seems like there is an engineering problem in using kernmantle-style ropes for hitch cords.

I did a number of tests last year on 8mm Bee-Line that point to a simple solution that preserves the best qualities of the rope while probably eliminating the herniation problem: remove the core.

Yale lists the rope with a nominal strength of 8000 lbs. I separately tested the core and cover for strength by making eye-2-eye slings of each, as shown in the photo.

The vectran core, upper, had simple buries about 9 inches long without locking Brummels, and broke at 9594 lbs.
The cover-only sling, below, also had 9-inch buries and broke at 6020 lbs.

I had enough material left to make a cover-only e2e to test in the field. It had physical properties virtually identical to the orginal rope: it was the same size, it was just as pliable as the original, and it worked just fine as a friction hitch. It seems unlikely the dense weave of the bury could ever herniate through the cover.
