/ What is the ideal combination of prussik, Ropeman & Tibloc?
Is there a scenario where you could not use a Ropeman or a Tibloc instead of a prussik? I am debating what to carry - I own a Ropeman but it's quite heavy for what it is. I've looked at Tiblocs but not used them. I've always carried a couple of prussiks.
What is the ideal combination of prussik, Ropeman & Tibloc for adventurous trad?
Your chances of getting a Tibloc to bite on both strands of a double rope are not good, should you need to.
Just keep carrying the slings.
Light and cheap. About fifteen different knots to use if necessary.
Also useful as thread or spike runners, abseil tat or abseil back up.
Ropemans are great if you don't mind the weight,
Prussiks are bling if light is your thing,
But Tiblocs are dope if you want to f*ck up your rope.
Hey, you're a poet and you don't know it.
A ropeman is great if you're only using a single rope, if you're using double ropes just carry two prussiks.
I think he knows all too well!
Just take prussiks unless you explicitly plan or ascending, hauling etc. They're just lighter than all the options, kind to your rope and far more versatile.
And potentially lethal. I binned mine after one very scary use.
I've heard they can strip the sheath. Have you had that actually happen?
A prussic will work ok on double ropes if need be I think? I haven't tried ascending that way, but using as a lower brake/failsafe while abbing, they certainly work very well over double ropes. Wouldn't be surprised if they worked that way for ascending too.
Two prusiks....versatile and can be used for a variety of other things at need.
forget the ropeman and especially forget the tibloc....I've seen a sheath torn up badly by one.
That said, I generally carry 2x short prusiks and 1x Tibloc as there are a few situations where I would like the extra efficiency of the Tibloc. Some equipment can easily be mis-used and Tiblocs unfortunately fall into this category. When loaded gradually there is negligible chance of rope damage but this requires care in use, including when ascending and situations with high shock loads need to be avoided.
A couple of final points:
- Mammut Contact 8mm slings are TEN times more expensive than 5mm prusik loops. I therefore carry slings to use as slings, and prusiks to use a prusiks. Saving the 19 grammes which each prusik loop weighs, does not seem a sensible trade-off against the risk of damaging my expensive slings.
- I also normally carry a longer un-knotted length (c.5metres) of 5mm cord and a knife. The tat is invariably used for abseil anchors, but it means additional prusiks can be made easily, if needed.
Guide plates like the Reverso can be used as ascenders. So if thats all you have, you can improvise the foot loop using the rope itself and get yourself out of the shit. Obviously it works with two ropes too.
i own a tibloc and a ropeman 1
tibloc has been used once in anger
ropeman has never been used when it mattered
ascending with a tibloc in combination with an atc xp-guide was still a pain in the neck but far easier than using 2 prussiks
carrying cord will always be more versatile than carrying a ropeman or tibloc.
i seem to recall an andy kirkpatrick article where he talks about using a ropeman as a runner when simul climbing
personally i would carry a device with a guide mode + prussiks/cord + a tibloc.
the tibloc is super light and well worth its weight if you ever need to use it
You're not wrong.
In the absence a guide plate, there are also hitches that can made made out of the rope that will work on the rope, and indeed much smaller diametre cord than the rope itself. I've seen people hitch 3mm cord with 11mm rope.
However, none of these are particulary useful when you are dangling in space on your rope. Not getting a guideplate nor a bunch of ropeslack there.
When is a Ropeman useful to have over a Tibloc or Prussik or Guide plate?
Also, when is a Tibloc better to use than a prussik?
Well, as wolfie says, you can't put a guide plate on without first un tensioning the rope.
There's less waisted energy with a ropeman vs a prussik. As for tiblocs, too teethy for me.
Microtraxion works as a pulley and ascender, is lighter than a ropeman Mk 2.
Tiblocs cannot be released under load, some prusiks knots can. In ANY situation where you may want/need to release under load, a French prusik will be far better.
In most other ascending and progress capture situations a Tibloc can be more efficient due to much less slippage. However they are still less easy to pull-on than full-size handled ascenders so it may be that for ascending a Bachman prusik is still the better option.
Micro traxion is indeed quite awesome, however I still wouldn't carry it normally. It's pretty spendy too.
However it's silly light and efficient. A go to for crevasse rescue, hauling, or lighter ascending work.
If you're being lazy.
Why do you carry a Tibloc then?
A tibloc and a rope man only hold in one direction. A prusik in both. One common reason to really need to prusik is when the ab rope gets stuck. You need to be on prusiks then in case the rope frees itself as these will still hold when pulled in the opposite direction.
A micro trax is so useful and much better than a rope man. If you want to carry something mechanical, then there's a lot you can do with it.
I'm having trouble visualizing this, could you explain the rope being pulled in opposite direction bit?
For example, you're on a 2 pitch abseil. You've just abbed down the first pitch and you're at the stance. You attempt to pull your ropes down and they get caught.
You have to prusik up the ropes to try and retrieve them. Whilst you're midway up the rope falls down with you attached to it via your prusiks. The prusiks are now upside down and they should hold (providing they don't snap - I don't know whether a dynamic fall would be enough to snap the cord).
If the FF is low enough and you're on dynamic rope... You've got a fighting chance. I would however move a clovehitch with me as a backup.
As the others have said, when the rope comes free.
Other places a prusik is needed rather than ropeman etc (I guess these have all been covered above):
escaping the system - to bundle the anchor lines together
when tied as a french prusik (although a ropeman can sometimes be used in this way)
when used as a thread
to stop a rope reverse feeding in a silent partner - but now we have reached the esoteric.
All interesting replies. We're not really seeing any 'advantages' to carrying a Ropeman or a Tibloc though?
Petzl tested a 7mm prusik in a fall (can't remember the FF), it held, but then 7mm isn't 5mm.
Much, much quicker to prusik with. So if you think you might be prusiking carry them. One common example: you climb 6b, your mate climbs 7b. You do a 20 pitch route which is mainly less than 6b, but with a couple of 7b moves. You plan to prusik these.
If there is any chance I might have to escape up an abseil rope (not unknown as I live in Cwall and am a coward!) I carry a croll chest jammer - not massively heavy and tried and tested.
While you are right it is possible, have you ever tried using a guide plate for that purpose? It is incredibly hard work, even when setting up a pulley system from the upper ascender. I would much rather use a prusik as the waist ascender and a tibloc as the upper if push really came to shove. Neither scenario is obviously perfect, now if I had something like a grigri or a trango cinch I'd be smiling when combined with a tibloc
Off the top of my head, I'd have probably gone for the other way around - Tibloc at the waist, Bachman above with a long sling as my foot ascender.
Having not played around ascending ropes for a couple of years that is not based on practical testing and I'm always curious about what other people do...
Only reason I prefer the tibloc up high is because it is easier to adjust it and get it to seat without shredding the rope. If I had a ropeman and a prusik I'd rather have the prusik up high. I'm just very wary of the tibloc as it is well known to shred ropes if not treated with caution.
I'd just take two prussiks over a tibloc. They're not that bad, the tibloc just slides around until weighted. Definitely wouldn't go near that for the waist, if you accidently unweight it and sit back down you might be going for a ride/severly damage your rope. Not great if one is using thinner ropes, doubles or anything like this, how well it works is carabiner dependent too.
However, with icy ropes one should probably carry something with teeth.
I have found that a reverso is a joke for this with a 10mm rope, but fine on a 7.7mm ice line.
One really cool use of a reverso to prusik is in converting an abseil into an ascent when you rap a few metres passed the chains at the next station as it takes less than a 3 seconds to rig. This is shown at multipitchclimbing.com in chapter 11, just search for "converting an abseil".
Yes, I have tried it and yes, I agree it's a bugger. And you have to unweight the rope to get it on.
Just a note on getting a reverso into prusik mode when swinging in space, e.g. having fallen off under a roof.
1. place foot prusik cord above you on the rope
2. tie an overhand in the prusik cord near the prusik knot
3. stand in the prusik and clip a krab between your belay loop and the foot prusik just above the overhand
4. sit down
This should leave you sitting in your harness with a nice loop of slack in the main rope to get the reverso on.
Petzl did have a neat video of this on their site but I can't find it.
Cheers. That makes good sense.
Steve Long did a 'how to generate slack at the end' video with a ropeman, never seen a petzl version.
