Belaying the leader with a Munter off of the anchors
|
To clarify Jim's comment about the "power point" belay, he is referring there to leader fall catches when their is gear higher up on the pitch, not to the factor-2 situation. |

Not sure why you would want to use a Munter, especially on multipitch. An ATC weighs very little and it is challenging enough to keep your ropes untwisted after 10 pitches. I couldn't imagine the frustration of using a Munter for that many pitches. |
|
The munter doesn't really twist your rope until it's weighted. |

I climb to spend good time safely solving problems with good friends. Just like in life, there are trade-offs that need to be known in different methods. We ultimately decide what we deem acceptable or not.Instead of hating those who have differing views or opinions as mine, I will read and learn from what is said...both the sound and unsound comments. Thanks to all of you who have participated in "enlightening" me! Climb safe. |

I do the same thing Ryan Williams mentions, and your follower should be cloved in the anchor anyways ja? So if fall is too much for belayer I always figured the anchor would catch them before they go too far up. |
|
At least with the ropes I have used, the Munter hitch "wants" to twist the rope while belaying. You have to kind of fight it with torque from your hands as you feed through. After a few pitches though, I started getting a few twists anyways. |

i like how the guy from texas immediately talks shit, without providing any insight on the physics that others elaborate quite reasonably on. way to be a typical texan douchebag, you live up to the standard that you and your fellow statesmen have set. |

( potomacmountainclub.org/con…) I just double checked, and it can be reversed ;) In any case, I like knowing there are two human bodies absorbing the fall/distributing the force--rather than my human body cranking on a hard point--be it a Munter, Guide, or GriGri that's binding the rope. |

Old thread but here's a few links on the issue for anybody looking up this topic down the road. |

Good link, Leroy. |

Thanks for posting this Leroy. Really good video, that clarifies a lot of the issues raised with alternative belay methods mentioned in the thread. Several things interesting to note, esp. at the end of the video with the f.f. 1.5 simulated lead fall - when the fall was caught with a belay device, the belayer was pulled up several feet, and surprisingly violently, whereas when caught on a munter, the catch was far less severe, which would seem to put far less force on the fixed point, and anchor in general. It seems that the catch with the munter was much more dynamic - something I'd never really considered. I've always used the munter for convenience, or when I'd forgot, or accidentally dropped my device. |

I'm a bit of a late convert to using a Munter directly of a BOLTED anchor, but it is very, very good. |

Belaying with a munter from (bolted) anchors has two distinct advantages compared to an ATC in guide mode. |

Once the follower arrives at the belay he can just keep going. No need to change anything. Also if the follower falls before the first piece of protection, the knot "flips" and the fall can be safely caught.Whoa! You mean to tell me that the Munter can safely catch a follower? Holy cow. I thought it was only good enough to catch a leader. Learn something everyday. |

My bad, I meant to say "(...)if the leader falls before the first piece of protection (...) |
|
I think the Munter on the anchor is primarily for bolted multipitch sport climbs. The fact that it can as much as double the load on the top piece compared to an ATC on the harness suggests it is not a great idea for trad protection. |

I'm with you rgold. Unfortunately videos seem to have such authority whether right or wrong. This is supported by the above poster stating that belaying off thr anchor reduced loads. |

the video made by the ACMG on fixed point belaying is sound and based on their testing and usage .. more than what we can say about many intrawebers |
