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

Blimey. Vids like that don’t do much for my recently acquired phobia of chairlifts.

Why didnt somebody press the emergency stop button.
We were going up the bubble from the bettex mid station in st gervais end of last wk when a guy fell down into the track behind the cabin we were in, not sure why as it wasnt busy, the lady lift operator tried to pull him up but decided just to push the stop button behind her, he wasnt hurt and saw him using it again yesterday.

Anyway, snowHeads is much more fun if you do.

It's likely that a "failure" on the arrest brake was present either through components or fudged in testing, as the Italian cable car was, to facilitate this.
In all probability the stop had been pushed (in a likely sequence of operation) at which point the line brake measures are automatically implemented, and need resetting to re-start the lift. If that failsafe system is impaired, then this can result.
At which point no controls have any real effect. Safety check routines should be fully implemented as the most important measure to avoid situations like this.

You'll need to Register first of course.

The emergency or other stop button has long since been pressed.
This is a lift that has mechanical failed and is going backwards due to gravity.
There will be a mechanical brake but I doubt the operators don't know of it's existance, let alone how to use it.
In many countries operators are tought the very basics of how the lift operates and how customers use it. They are not tought how the machine works or how to do any maintainance including how to clear faults or how any of the backup systems work.
The 1959 Draglift that I run at work has an electrical braking system and a mechanical (car drum brake) system as well. If you use the mechanical one it trigger the electrical one also. But once the lift has stopped, inertia and friction withn the system itself is all that stops it moving. Being a one way lift it does have a mechanical rachet system to stop it going backwards. However with a fully loaded lift on a cold afternoon I have had this fail. Once the lift stopped it started to go backwards, it's only a Pomma type lift and most people have the good sense to get off. But it still started to accelerate because at lest 10 people didn't get off. I had to put full body weight on the mechanical brake to stop it. Empty it takes not much more than the weigh of my arm to stop it, even with the power off!
Detachable chairlifts like this one have no anti reverse rachet as the are designed to be run in reverse. The saving grace with this particular lift (and I think true of all detachables) is as gravity force the thing backwards it has to drive the whole system backwards incluting the load/unload mechanisms. These are mechanicaly inefficient, hence the lift running at a relatively low speed and most people able to get/fall off in the loading area.
Fixed grip chairlifts are wild when the run away, but all should have anti reverse mechanisms, that should be checked daily - in France, Italy, Switzerland, Austria, Germany this check is required by law...we have 3 pomma lifts and 2 rope toes and have been visited twice this season by the authorities (the french are currently taking lift safety very seriously.....something in Italy last autumn bla bla).

@robs1, indeed very interesting, after the Galtur failure the issues IDRIS raises about staff training and knowledge is a crucial one.
I wouldn’t want a pilot getting on an A300 and asking the passengers ‘How does this work, then…?’
