door close buttons : LUSENET : Elevator Problem Discussion : One Thread

I am doing some research on impatient behavior and I have read somewhere that elevator munfacturers have to replace 'door close' buttons more frequently, worn out from impatient stabbing.

So, does anyone know if this is true and are there some statistics about this? I need some sources.

yeah thats right....and on a lot of older lifts the door close button only works when the lift is on attendant control, not on automatic operation

do you know where this information comes from? Are there any statistics about replacement of 'door close' buttons?

from experience:- most calls to lifts when used in a high-rise housing are to the doors ranging from damage caused by people banging or kicking or alternatively by wedging the doors during removals, cleaning, deliveries, This damage ranges from safety edges smashed, vision panels broken, buttons damaged. It seems strange but true that those who are the most impatiant and do the most damage are those wanting the lift most. I have found door close buttons damaged and a wedge under the leading edge of the car door, the wedge was clearly visible and took only 5 seconds to remove. On one lift where we had repeated damage at the ground floor we fit a highly polished stainless steel mirror and found that people were too busy looking at themselves to notice that the lift took over 30 seconds to reach them. and vandalism drooped to almost nothing I would appreciate your findings being posted on this site when you have finshed. They should prove fascinating as to why people will only wait 30-45 seconds for a lift but half an hour for a bus or plane or underground train
