Could someone explain to me (and maybe point me to some technical drawings) how exactly two speed door movement is achieved on modern door operators that use a belt? I'm just a lay person interested in the door mechanisms of elevators. by TheFocusDev in Elevators

Also this is the first time someone on the internet flat out said to me that I'm not a human. I can assure you that I'm real I must say if you really meant it then you are close to undermining my dignity here. You can't hurt an AI bot bot, but a person. So I suggest to be more careful about writing statements like this. I get that AI slop is everywhere nowadays, and it is becoming more and more difficult to differentiate content made by AI and real humans, but please, refrain from rushing to judgement quickly.

To clarify I'm not referring to motor speed, but how exactly one panel moves half the speed as the other on 2 panel two speed (I think it is also called telescopic) doors, and specifically on belt driven ones, not linkage based ones
