Don't these things have emergency stop buttons and both ends like escalators?
Edit: At, not and. Fuck you edit button.

Yes. Yes, they do.
However, that's not an "emergency stop button" situation.
That's a chairlift that's gone into "rollback"; basically it's stopped when loaded on the "uphill" side, and for some reason the brakes have failed. There's two brakes - one on the input to the gearbox, and one on the bullwheel. Normally the input side brakes are used, and if the lift detects it's rolling back via its cable speed detector, the bullwheel brakes are slammed on on automatically. If that doesn't happen fast enough, i.e. before the lift gets to about 5km/h, or, in real terms, under about half a second, the lift's inertia will win and it will smoke the brakes. At which point you can do fuck all apart from pray not too many people get killed.
There's been at least 3 points of simultaneous failure for this to happen, but none of them involve somebody not "pushing the emergency stop button".
I am an actual chairlift maintenance person, most of the lifts I service ore of that exact type.

Thank fuck you're here or we'd have never known.
From now on I'm only using chairlifts if there are a sufficient number of tubbies on the downhill side.
