The dissemination of technical elevator repair information to untrained individuals searching for ways to save their organization some dough is doing the entire industry a disservice.
These type individuals - usually building maintenance personel - have sought out techincal elevator information in the field for years and the internet is simply another avenue for them. Just last month in my service area a millwright (in this case millwrong) who thought he knew what he was doing got himself killed under a falling material lift.
Having a "elevator mechanic only" section in this or similiar industry website, protected by password, is a good idea and I am sure feasible if someone was willing to put in the effort.
Look at the thread "Hydraulic Elevator Floor Misalign" directly below this one for a perfect example of an indvidual with obvious little elevator repair experience looking for a fix. Someone could easily steer him wrong intentionally or unintentionally, and tell him to make a valve adjustment that could send his elevator crashing into the pit with himself or the riding public in it.
In that thread, experienced guys disseminated technical information to him and/or took his questions as a platform to go off topic or for insider stories - thats all well and good but the OP - "Sirnobody" stopped responding to the thread long ago -mid flight - hope he's not hurt!!
