Most elevators have both an electric eye and those pressure sensitive panels to reopen doors if someone is trying to get in while the door is closing. What happens if I just put my hand in an inch or two, so that it does not activate either? What prevents me from being injured? I assume that closing force is limited. What is the door closing force.
ASME A17.1 is the standard for elevators governing all the elements. ASME A17.1 (2007): Safety Code for Elevators and Escalators … (PDF around 25mb) Closing force seems to be a maximum of 135 N or 30 lbf according to 2.13.4.1
And you have to leave a certain space at the bottom of the shaft for finger tip cleanout.:eek:
Thanks, that is exactly what I was interested in finding.
Putting you hand between the doors but not across the safety edge can be dangerous. Sorry but I have forgotten what force was generated by the door closer. But if you fingers are small enough and or the door safety latch is a little sloppy in adjustment the door switch can make up and the car can move.
