There has to be way to much friction in the mechanics for that to happen. No? Mitch. One of the greats. Uncopyable.

- peller 9y agoDo escalators not come with a ratcheting mechanism to prevent exactly that from happening? Seems to me like a serious design error if not..
- euyyn 9y agoI guess they were designed to run in both directions, meaning you can't mechanically lock the "down" direction.
- FussyZeus 9y agoI mean, it's probably a Chinese escalator. We didn't get the term "Shenzhen Quality" out of thin air.
- StavrosK 9y agoThat seems a bit of a misnomer when everything is made in Shenzen.
- bykovich2 9y agoFunny, it seems increasingly apt to me.
- seanmcdirmid 9y agoMost escalators used outside of China are not made in Shenzhen.

- semi-extrinsic 9y agoJust sayin', if I were building an escalator I would definitely use a wormdrive (or similar) gearbox, which physically cannot be backdriven.
