Hey, guys. Thanks for all the help. Had a long day and just got in.
john jay - yep...it's a roped hydraulic. Not sure if I have an overspeed collar.
it sometimes takes all day to get it off the safety because it happens on the top floor. This time, it got stuck on the top floor and they stated that something snapped.
Additionally, they said the temp sensor in the oil tank broke and they replaced it. They said this is common every 5 years.
But, they still don't know why the safety keeps going off.
They said they will be replacing the old contactor. They say that the only thing they can do is keep fixing it and keep going by baby steps.
From what you guys are saying, it really could be a number of things and best way is to get the professional to figure it out. The problem is they can't seem to do it. I'm really loyal and so I've been sticking with the present company for a while but I really need to get this elevator running...
Do you guys suggest a certain way to resolve this? For example, would hiring an elevator engineer to consult with present elevator company help? Or is there a certain type of company I should be using? Like union as opposed to non-union? Or should the techs have certain type of accreditations?
Thanks in advance for your help, guys. You guys have been great...
Ah yes it can be a drama if the safety gear is in on the top floor especially if the headroom is small. They have to be able to lift the car to disengage the gear and may not have room to do it in or to work.
Just another couple of points. I have worked on lots of roped hydraulics, but it was a while ago so bear with me. We had lots of problems with bouncing in of safety gear for no reason. By that I mean it didn't actually actuate or overspeed, but the lift or diverter sheave momentarily stopped on the rails. We had to check things like: rail clearances from S/gear, governor rope pit pulley weight too heavy and pulling the actuating arm down, gov rope loose, rope diverter sheave rails dry, rope diverter sheave rails loose and cause cross bar to bind in slipper guides.
All of these things should be checked. What is the manufacturer of the lift?
