Bad Rope Burn Belaying with Gri-Gri
|
so i guess my questions are, |
|
If you fully inhibit the cam, you won't be able to catch a leader fall by having a good brake grip as you would a regular tube device. So where the brake hand was, or should have been, the same result would have happened but to both hands. |
|
I've taken a liking to the Trango Cinch for that reason. I don't think you could accidentally keep the cam from locking off since you push it open to feed instead of holding it shut. In the gym a couple of weeks ago I looked down as I fed the last arm load of rope to my partner for him to clip the anchor at the top of an overhanging route and he fell without warning. Even though I was holding the cam open with my brake hand thumb as I paid out slack, the thing slammed shut and launched me. |

Just last weekend I was out doing some aid practice. I just bought a Gri-Gri and my partner wanted to try it out. Near the top of the route a hook popped and I went sailing 20' down the wall even though my last piece just before the hook held. I'd call this belayer error, but due to the complexity of the device. He was holding the brake open to feed me rope and when I fell, squoze harder. |

I too, have been dropped with a gri-gri. The bottom line is find a device that works well for you and learn it and use it right. Don't be lazy or take an auto-locker for granted. Phil, I'm sorry your hand got jacked up, Hope it heals up right! |

Both of the devices ( grigri and CInch) are auto lock assists. this does not mean have a smoke and a brew while belay8ing. So keep you head and eyes up and one hand on the rope. |
|
curious what size rope it was? new? 10-11mm is the rope size allowed in the manual. most ropes used now are smaller. |

A climber in JT last weekend died when he fell and hit his belayer then continued to fall 100 feet to his death... I am not sure of the rest of the details... Or what might have been done to prevent it... |

I keep three fingers on the rope with the device basically balanced on my index finger like I'm holding a wine glass, and I use my thumb to nudge the edge of the plastic lever to feed slack. I've also cultivated a habit of keeping the device locked off while I'm not actively feeding slack by putting a small amount of tension between the device and a two finger-grip of my feeling hand - works for the sake of avoiding cross-loading as well. It is your design, though. Do you think that nudging the bar instead is equivalent to clamping a Gri-Gri shut with an entire palm? It seems to me that the slightest tug on the rope makes the thumb pop off the bar...There is no need need to keep the cam open by pinching at the fulcrum. It is all about the motion you use when you feed out the rope. Unlike a gri, you do not make a motion of "handing your belayer a armful of rope." This upwards motion will cause the cinch to lock up. Instead, make a motion of "stabbing yourself in the gut" while holding the fulcrum with your brake hand. Basically, if you keep your hand low and pull horizontally to the ground, the cinch pays out rope very fast. As soon as there is an upward tug, it locks up. Evan |

I was belaying last night and I noticed that my mutant-sized hands are so large relative to the device that my thumb nudges the bar whether I like it or not. |

Wow. This story hits close to home. I was climbing Swoop Gimp or Be Dust in Zion in 1997 and had the EXACT same thing happen to me. The only difference is that I was about 30 feet off the belay with maybe 5 or 6 pieces in between us. I was the climber and I took a head first 100 footer catching nothing but air. My partner burnt through a glove and then injured his hand pretty severely. The irony of it was that I took the fall, but it was him that got hurt. My memory is fuzzy, but I think I actually had to lower him because he couldn't grasp anything. At the time I worked at a big climbing gear company (partner, too, same company)and people saw his hand and the story got around pretty fast. |

just an fyi: anyone jugging lines should be tied into the end of the line they are jugging, and periodically tie back up knots as you move upward... |

It keeps the device a little farther away from the harness and a little easier to manage with big hands. Anyway, I just put the facial hair to the face and think I see you at RNJ all the time. I'm the other tall skinny dude in the gym. But, now, we're hijacking the thread. Evan |

I'm just always extra careful that my gear is in good shape and that I'm properly daisied in. |

Interesting that there were two nearly identical accidents. It just shows that if it can happen, it will happen..... and more than once too! |

My left hand still mildly resembles raw hamburger is a few places, but is definitely getting better, those special blister bandaid's and some good ointment helps tremendously. Very good point Andy regarding aid falls, in my [limited] aid experience, i've noticed that especially on harder routes in sandstone, gear is likely to fail suddenly and without warning; Tim had both feet in the aiders on the alien when it very suddenly ripped out of a crappy pin scar, still no excuse for me futzing around in the belay seat, but I think it caught us both off guard. I think the extremely sudden nature of the fall and that it was 3 feet above a hanging belay contributed to the belayer error on my part; def. should have had a better backup/knot in the rope though until he got few solid pieces in. And I correct my earlier statement, the end of the line was knotted. The rope was a 10 mm. line I believe. The grigri was my partners and it was his suggestion to use it, I neglected really making sure I remembered how to use it though after not having used one in a about a year. |
