Nope - Elevator failure in Hong Kong
/s/Elevator/Escalator/
Do escalators not come with a ratcheting mechanism to prevent exactly that from happening? Seems to me like a serious design error if not..
I guess they were designed to run in both directions, meaning you can't mechanically lock the "down" direction.
I mean, it's probably a Chinese escalator. We didn't get the term "Shenzhen Quality" out of thin air.
That seems a bit of a misnomer when everything is made in Shenzen.

Most escalators used outside of China are not made in Shenzhen.
Funny, it seems increasingly apt to me.

Just sayin', if I were building an escalator I would definitely use a wormdrive (or similar) gearbox, which physically cannot be backdriven.
