Rope type when bringing 2 climbers up a multipitch
|
What is the current accepted rope type for bringing 2 climbers up a multipitch route. I've been using 8.4mm half ropes, red tied to one and blue tied to the other. I want to know if this is okay. If not, what is? |
|
That's the way to do it. |

You can bring up two followers on half/twin ropes, but you will have more stretch on each rope if one of the climbers falls and you won't have the edge/cutting protection of a single. |
|
I always use half or twins when bringing up 2 seconds. Works well. |
|
depends on what you have with you and what your are comfortable with. Could also isolate a 10ft bight on a single and have your weaker follower tie in there, and the stronger on the very bottom. |

Yeah using half ropes is pretty common. A top-rope (that is following) fall won't put nearly as much force on a rope as a lead fall, so this is fine. It will be a bit more stretchy for the fall, if one of the 2nds falls, but not huge compared to, say, sling-shot TRing the same distance on a route. |
|
You're fine with 8.4 with a second on each rope. |

one important note ... twin ropes are not recommended for bringing up 2 seconds |
