Tom_Ski, Saw that, great work by the patrollers, getting it done when needed. 
Back up and running in 31 hrs apparently, good going by the mechanics.

Well, the person's real but it's just a made up name, see?

Great response.
We visited Winter Park in January 2001. The coldest I’ve ever been … -25C on an open chairlift at the very top with a strong polar northerly. Ended up buying the HotHands warmers for mitts and boots.

Anyway, snowHeads is much more fun if you do.

That’s an interesting theory. The clean break in the arm looks like it could be consistent with that failure vector. OTOH, it’s not like a manufacturing company, the American arm of the French manufacturer Leitner-Poma, that makes lifts for ski resorts wouldn’t have engineered the components with a big safety margin for temperature fluctuations because they didn’t anticipate them. The comments on the article are worth a read if you’re interested in such things - many of the posts come from lift industry types. One of them suggested everyone just quit speculating why the beam failed and wait for the official report.
The good news is - they already have the replacement part installed. Should be back up and running soon.

You'll need to Register first of course.

Geez. I ski there frequently and use that lift a lot when I ski there. I’ve never heard of a lift doing that. It’s a bit concerning to say the least. Hope they release more info about what happened and how it can be prevented. Hope the injured are going to be ok. Sounds pretty bad.

Looking at the photos, the fracture runs right past the weld where the cable conduit is attached, which is more or less dead centre of the beam, at the maximum stress point, bad place to put a weld?
That's not a crack, it's a fracture, it's a clean staight brittle fracture to start with, then a jagged ductile fracture as the crack propagation slowed down. It must have made a hell of a bang when it went! Definitely a few thoughts of "WTF WAS THAT!!!"

In frequent spells it’s a very cold part of the contiguous 48 states. Close by Fraser (frost hollow) records incredibly cold temperatures.

Been a few decades since my last engineering exams, but surely the centre of the beam would be at the lowest stress, closest to the neutral axis? The bottom of the beam would be under maximum tension (hence the location of the crack). |
I was referring to the end to end centre, not the top to bottom centre. The weld that I was referring to, was not the welds around the pivot pin, but the small weld holding a conduit to the bottom of the beam.

Ha - yeah - realised that just after I posted, hence the rapid delete! Not fast enough it seems

And love to help out and answer questions and of course, read each other's snow reports.

The folks at Superdevoluy were stuck on the ride for 2-4 hours.
Very cold.
