Another Accident due to mis-use of the Gri-gri

jesus christ, if you treat the gri like it's a standard tube device you'll kill someone. |

Well, it'll be interesting to follow the true adventures for a couple of years and see if T-eli-luc don't end up with a drop between them - wonder what odds would the pros in Vegas would give (on the bold assumption you're all still climbing in 2020). |

Merely observing 1:3 odds may actually be within the realm of possible over four years. We'll see... |

"Myah" is the inverse of "feck". ;-) |

I decked in April from 30ft up. My belayer was using a Grigri 2 and, I assume, did not have their brake hand set. The rope flew through the Grigri and I did not stop until I hit the ground. It happens.
Always use a brake hand. reddit.com/r/climbing/comme… oh and in case anyone missed it ... the deleted rock and ice video where the grigri didnt seem to function very well "as a tube" should the camming not engage youtu.be/4A8-jsLAZV4 |

Yeah, waving your break hand around in a circle like you're reeling in a trout while repelling is "proper use" of a grigri, and in no way is why it failed as a tube device... |

There was no visible movement of the cam. Rope: a short length of 9.8mm in okay condition. Not fuzzy yet. Climber weight: 130lb Rappel glove: OR Airbrake that fits me well With the rope running off the end of the device, I found it impossible to stop with a single brake hand. I just slowly slid down the rope. I could stop by squeezing hard with both hands. With the rope running off the right side "rope guide", I could stop with one hand but just barely. Having the rope run off of the sharper left side provided better braking, but it still took a lot of work to stop. I am not going to try dynamically loading the device, as it was hard enough to brake when gently easing my weight into the rope. I get way, way more friction from body belay/rappel techniques than with a disabled grigri. --- I have tried using a Grigri threaded backwards to test whether it would in fact behave like standard tube device. IMO it did not provide enough friction to safely arrest a fall. I think Jim T. has some figures on this. ------ perhaps you could run for tests for us catching a few grigri whippers with the cam tapped down with a few wraps of duct tape? i suggest proper backups or using someone you REALLY dont like ;) |

The reddit post is a joke. "My belayer dropped me". no details, no nothing. The video shows a bit more but its not perfectly clear. It sort of suggests he opened the lever in a state of panic but it's hard to tell. |

Jimmy Burckhard, 31, was climbing the bolted route Foot Fist Way (5.13a) in a limestone canyon southwest of Rapid City on September 26. He had previously worked on the route a couple of weeks earlier. On this day he climbed partway up the route, yelled “take,” and his belayer held him for a rest. He continued up the climb and then, at about 70 feet, near the top of the route, he let go again. He expected to take a short fall, then lower and rest to attempt the redpoint. Instead he plunged toward the ground, impacting on his heels. Burckhard broke both feet, his wrist and thumb, and three vertebrae in his back. A local climber hiked out of the canyon to a point where he could get cell reception and dialed 911. Responders carried Burckhard out of the canyon to an ambulance. ANALYSIS Burckhard was climbing with one of his regular partners, and both men are very experienced climbers. The belayer was using an assisted-braking device, and when Burckhard asked him after the accident what had happened, he responded, “The device failed.” No further information was available. (Source: The Editors.) publications.americanalpine… getting dropped or dropping someone aint any joke ... but sadly it seems to have become more "acceptable" woohooo ... 15 post limit hit again !!! |

Perhaps you don't understand physics, but a big part of using a tube style device is keeping your brake hand below the belay device so you create an additional point of friction on the brake side of the belay device. Go try to repel using an ATC with your brake hand above the device. And for good measure make sure you are very jerky as you lower yourself. Let me know far you manage to lower yourself before you lose control and deck. |

BB, after rereading the thread title you are correct. All belay devices are subject to misuse. There is no getting away from human error. We can mitigate the error by extensive training but it will never go away completely. |

bearbreeder, how many people have you dropped since you started climbing? |
