In the case of normal daily operations that's basically it; however as with everything there are variables. The Emergency Shutdown would also be used for other reasons. I've used the E-Shutdowns in motor flashover and bearing failure situations where I didn't want the drive to electrically decelerate the lift, I just wanted it off. These situations should be few and far between though. When I was a lift op we were also taught to use it when someone's life may be in danger (guests or staff) or the lift equipment could be damaged. We're all fixed grip though; and at least the way ours are setup - all do stop faster (by 1.5 - 2 meters) with the E-Shutdown.

What is a motor flashover? And I am guessing bearing failure on sheaves? Would you happen to know if stopping faster is still true with detachables?

Thanks Allan

A motor flashover in the simplest explanation (as was explained to me, anyways) is electrical arcing between one rack of brushes and another; with often disastrous results. I was also speaking of bearing failure in an electric motor. I don't know a lot about detaches, but I believe that the E-Shutdown in several cases is longer.

Thanks for all of your information :)

Do not forget that that e-stop in almost all cases is now to be relabeled e-shutdown. So on new installations there may be an e-shutdown and an e-stop. The e-shutdown will still open the arm contactor and come to a stop via mechanical friction. The e-stop will be the equivelant of ramp-2 on detachable lifts.

Does this apply to all manufacturers?

Don't think so, Poma at least has the same emergency shutdown and normal stop they've always had.

Allan/skiliftsrock, all our detaches stop longer on an emergency shutdown. Not much, but noticeable.

Motor flashovers aren't any fun.

Charlie-- the speed control switch on Doppelmayrs has four positions. Low is maintained, medium is maintained, and fast will return to neutral once you let go of it. Fast speeds the lift up just like more common pushbutton would. Neutral means the lift can be sped up, it doesn't do anything otherwise. Because low and medium are maintained-position functions, the operator can lock the lift in that speed setting until he or she is ready to go back to fast.

Skiliftsrock-- lift control buttons and switches aren't exactly unique; they're industrial controls found in many applications such as factories and plants. They're not cheap either. That being said, why do you want an old control panel or buttons?

Just wondering if it was even possible. Also I don't have a good reason. And maybe if there was one just to have. I'm not sure

Thanks. I haven't been "close up" with any recent LPOA installations and I wasn't sure if it was a new standard set by ANSI.

Search for stop button, or pushbutton on eBay and you'll find tons of them for cheap as dirt :) Wait... why do we pay 50 to 100 dollars for a stop button again?

I never thought to look on ebay, Thanks a lot!

I think we pay that much for one because the manufactures want their money, and or that it has to be a certain kind. (Do they have to be a certain kind? If you push the button it just completes a circuit right?) Thats my best guess.

After a conversation with Sid Rosland from NSAA at the RMLA, he told me that all e-stops were to be relabled as e-shutdown and have a guard installed. I do belive it is ANSI and will follow up.

This is correct. We did the whole deal last season, had to change button colours as well (CPTSB mandate, not ANSI, fast is black, medium is blue, et cetera), lots of extra buttons floating around the electrical shop.

Jimmi-- I haven't dealt with any recent installations in years either :devil: but we have gotten some upgraded control systems in the last couple of years. No more Afficheur BC-40s, we actually have touchscreens now!

What are the features in a touch screen unit?

Some Neat stuff.... I'll cover the stuff that the ops use and one of the techies can cover the mech side of it.

It shows the zone info, faults, speed, stopping dists, It allows us to test the zones, Shows the chair spacing, any fault that is bypassed, shows the amp / volts of the elec motors. (this is all on l-p stuff)

Wow. That sounds like a great feature. I have only seen it used once on a Partek Tripple chair and I took about one second to look at one on the lift at my resort at the lower terminal. Is there a touch screen system at both terminals?

Far as a I know all new Detachables will have it at both stations, Far as Fix grips I'm not 100% sure, But i think they are getting touch screens too. (I'm only speaking about L-P Lifts)

In this pic sideshow I have a pic of the control center on the Village Express, Take a look at my other videos too that I have of the skilifts.

Thanks for all of that :)
I have seen all of those video's many times. I enjoy watching watching them. Thanks for making them :) Were you working on all of these lifts when you took the videos?

Yep. I have some other videos that I have not posted yet. When I have time to edit them I will post them up.

Awesome! One day when ever I get an youtube account I will have a bunch videos that I would like to share with everyone.

I have some good ones of the tours I have gotten and some of a full start ups. :)

I have a question about a chairlift's controls. First off, what are the common buttons on a high speed chairlift's pushbutton station? Also, what does it do when pushed.(if it isn't obvious such as start, slow, fast etc.)


You got it. Pretty straight forward. Start, Stop, Slow, E-Stop etc.
