Are Alien Cams Gonna Kill You?
|
Recently, I had an Alien cam (the purple size, which is roughly equivalent to the #1 BD cam) completely fail on me. The failure was catastrophic: the lobes completely separated from the stem. I realize that cams can fail when placed poorly, but this cam was set very carefully and properly in a clean, hand-sized crack. What's more, the previous day I encountered a climber who had a small blue Alien break when he fell on it while leading. To be sure, my stories are purely anecdotal, but I seem to keep finding climbers who have their own Alien "horror" stories. Am I the only one who thinks this is an issue? While I'm not out to slam the manufacturers at CCH, I'd like to hear if anyone else has their own examples of cam failure/problems. |

unless you decide to climb with them they're perfectly safe! |
|
like dude,,,,,, WHERE HAVE YOU BEEN???? |
|
Dude, what I can't beleive is you used a purple alien! |
|
Aliens don't kill, they just want the same opportunity to the pursuit of happyness as everyone else. |

Additionally, even after some of the cams have been recalled there have been issues with quality control-oops- there are lots of threads on this at rockclimbing.com |

Hey Andy, |

my aliens are over 10 years old and none have even failed. so i continue to use my purple alien and some other odd colored large ones. I love the look on peoples faces when you pull out the HUGE alien. Most have no idea anything other than black, blue, green, yellow, red exist. I have a grey, purple and orange also. wish they had a #6 camalot equivalent...now that would be something. |

You need to get out more, on second thought, don't go out more and sit at the computer reading RC.com and you would have known this. |

There is only one way to save yourself from Aliens! Let me have them and I will hide them on my gearsling. Please only send black through red, I will pay S&H. |

Jed Pointer wrote:The failure mode on post dimple recall Aliens is also very disturbing - ie, what appears to me as overheating the fine wire they use (ie, high strand count cable overcooked in brazing process perhaps to compensate for the undercooking of prior failures).For kicks and giggles a while back I threw a Red Alien onto the pull tester and pulled it to failure (I'm the guy over at RC mentioned in asmith's post above). It failed a bit below rated strength (11.3kN, rated for 12) by way of the cable separating from the head. There's a thread over on RC with all the specifics (video of the test, a datalog of the forces, more pics), but here's a closeup of the break: Someone else on RC said they worked with a metalurgist who was willing to take a look at it, so off it went. He said the same thing as Jed- embrittlement of the cable wires due to overheating, evidenced by the distance the braze wicked up the wires. Personally I don't understand why CCH doesn't switch to a swaged head and avoid the problem altogether. Or barring that switch from the brazing torch to some sort of induction heating fixture to better control the temperatures. But they seem rather set with their process and unlikely to change it. Oh well. -a. |

Aric-- let me be the first to welcome you to Mountain Project. Your posts have been welcome data points in a sea of speculation... |

Thanks Larry. I'd heard that the signal/noise ratio over here was much better, so finally got around to taking a look and stumbled upon this thread. So far I'm liking it here... :-) |
