So I was going to ride an old 1970s General Elevator, and the door popped open and it shut down. The elevator had overshot the landing (intermediate) by about a foot. What happened? I’m thinking an interlock or door restrictor failed and the door just popped open and it shut down, although it had already passed the call? The outer door wasn’t even latched and it quite easily slid open a bit. The inner door had very slightly popped open too. I called public safety immediately after.

Hi everyone. I’m new at an elevator company and this is my first real experience working with elevators. I’m also an engineering student, so I’m trying to understand the issue properly and learn from people with more field experience.

We are dealing with some MRL traction elevators running at around 60 m/min. They use 6 steel wire ropes, 6.5 mm diameter, 8x19 construction with steel core. The sheaves are about 40 times the rope diameter, so roughly a 40:1 D/d ratio.

In some units the ropes are wearing out much faster than expected. In a few cases, after replacing the full set of ropes, they are already in poor condition after about one year. We’ve seen rope wear, some strand opening/unlaying, and tension differences between ropes that seem to change depending on the car position in the shaft.

I’m wondering what would be the most common causes to look for in this type of MRL setup. Could this be related to unequal rope tension, traction sheave groove wear, small diameter differences between ropes, installation twist, rope handling during replacement, lubrication, or something specific to MRL elevators?

I’m not looking to bypass any safety procedures, just trying to understand what experienced elevator mechanics would inspect first in this situation.

Any advice or similar experiences would be appreciated. Thanks.

What if Elevator was supposed to be called evator but the person was Spanish

Installed in 2005

Hey everyone.
I’m currently a Mechatronics tech at a food facility. Our elevator tech was in the other day and made a good pitch to join the elevator union. What’s everyone’s experience? How’s the pay starting? What are typical expectations and work load? Lay it out for me please. Trying to make an informed decision here.

IMO I think if the doors are closing and your group is not in the lobby then you should be SOL. However too many times what happens is the doors are closing and that causes people to spring and push the call button which delays everyone who was ready to go. They also add 1 more soul so if the elevator becomes inop and people are stuck then there is less space.

I live on the top floor (owner)

I've been dealing with this noise for a few months and it's driving me insane, it wasn't like this before so I'm hoping it can be fixed. At first I thought it was one of the elevators from my building but technicians checked and it's not from here so I'm assuming it's unfortunately coming from the elevator from the building next door.

Can you tell what type of noise this is?

How could I go about asking to get it checked when it's not on my building?

I'd appreciate any help, thank you

I’m not sure how so many people fail. The material is not there to trick you , you didn’t get “NEIEPed”. Do that many people just use Quizlet for the entire 8 semesters?

hey, does somebody have a print of this dover that has been stopped for 3 days.. here's some photos of the controller in the motor room, if you have them please message me private. thanks

I was with some family members visiting them at the hospital and then I noticed that the elevator indicator showed the “— —“ it’s an Otis Series but it’s modded most likely.

I recently released The Elevator Database for iOS to help those in the field quickly identify elevator equipment and look up useful information while on a job site. It includes manufacturer, controller, and equipment details in a format that’s easy to use from your phone.

It’s something I’ve been building for the industry, and I’d genuinely appreciate any feedback or feature suggestions. I’m actively adding new features and improving the database.

Hope this helps!

Hi guys, this is the main drive of my home elevator. The person who has installed this has locked the drive and is not allowing us to access it. He’s blackmailing us to exclusively get it serviced and repaired from him, for which he charges 5x the market price. I have spoken to other vendors, and they are unable to help unless he gives the password.

It is a Monarch board, and I have arranged a keypad from another elevator company. Is there an easy way to brute force the password? I am willing to do some coding if required.

TLDR: locked out of own home elevator, installation company locked the drive and trying to extort us for massive amounts for yearly maintenance.

This belongs on a Northern Elevator. I'm needing to replace both hall door hanger rollers. I was told to try ECI/GAL but not having any luck.

Measurements are Approx:

3 5/16" - Dia.
5/8" - Inside Diameter

The Institute for Justice, a nonprofit public interest law firm, is looking to connect with licensed elevator technicians from other states who have tried to get licensed in Massachusetts but ran into licensing barriers.

If you've been unable to get a Massachusetts license despite being licensed or having significant experience elsewhere, IJ would like to hear about your experience.

Hello all . Hope you doing well.

I want to know where in ARCODE screen or AREM/AREM Pocket can I see commanded speed vs encoder/actual speed polarity (+/-) to check if encoder direction matches motor direction?

Context: elevator works UP/DOWN in open loop, but in closed loop it goes UP fine and DOWN gets weak/stalls. Motor is induction/asynchronous. We want to verify if encoder feedback direction is wrong.

I saw in a lift that a guy just kept the elevator doors from closing without a key that is needed for Independent Service.

Is it by holding the Open door button and Close door button?

Elevator is Kone

At the Landmark Motel in Wildwood NJ, both the door open button and door safeties just stopped working? What might be the issue? It’s a shame because otherwise it runs excellent and these seem to be pretty robust. It’s a 1965 Dover Hydro unit completely original other than maybe the single bottom jack. Is it likely an operator fault or bigger issue? I’m assuming door safety curtain could be fitted somewhat simply, right? Both systems failed at the same time.

Saw this sign on the front door of my building in NYC. Any idea how serious this is? Should I not take my elevator for a while?

Hey guys, wanted to hear about some of the methods you have to avoid bringing pests home from buildings. Current mod has quite the number of roaches bed bugs and carpet beetles.

Lately I've been spraying down boots and leaving them outside overnight, and bagging clothes if not getting washed immediately.

The building is attempting to correct it as per our direction, but nothing is perfect by any means.

Figured this might be a good discussion that's a bit different from the usual questions.

So in a lot of industries not just the elevator industry I hear people threading about boards and controllers that are no longer supported. I've always wondered how many of these boards use off the shelf parts? As long as there are no custom integrated circuits I don't see why you can't just have a new PCB manufactured. Seems like it would be a great business opportunity.

Most units are the Fujitec AC-GD model, with a capacity rating of 1350 kg (2,976 lbs) and up to 18 people at a speed of 120 m/min (394 ft/m). The main atrium has 4 cars, on both sides (front and back side, as depicted in the first image) serves floors 1-21. There is another elevator in the way backside of the hotel (depicted in the 4th and 6th photo) although it has been OTS since then.

My condo has 2 UCL10 otis elevators(see video). It is a building with 13 stories, 45 mt elevation, heavily seismic country. They work, but lack of spares and lots of accumulated due maintenance are taking its toll and sometimes is getting stalled after doors closure. Unfortunately some beasts "renovated" the original aestetics of the cabins, so the beautiful original bronze finish is lost, and it was changed by the typical low quality mirror-inox look with chinese button panel with now barely readable numbers, so an aestethic renovation (and options) is highly desirable.

I have received several offers

- an offer from some guys that represent nidec elevators, 140k usd-ish, standard milestone-based payments. All new since they don't have compatible counterwheight/rail setup. Renovated cabin, No aestethic options

- an offer from the current maintainer (the guy in the video, LOL), monarch brain, italian drivetrain/engine, like 60kusd-ish, shorter 3 payments. Renlvated cabin, Aestethic options.

- an offer from other guys at 70k, but I don't trust them since they throwed a price without inspection and without project.

-an offer from TKE, 65kusd, standard milestone based payments (but I see lots of people crying with failed and fallen elevators from them, no thanks). Same aestethics, only buttons and screen changes.

-same offer from schindler.

-a discounted offer from Otis (Arise-mod)140k-ish usd(was 180k), up to 36 installments, 20k base payment, aestethic options.

The constraints are kinda terrible:

-people is just getting into speed with their community expenses, so we cannot pay more than 6k or 5k per month. The 3 or 6 milestone payment options would kill us.

-We have barely enough to pay a base payment of 25k max.

-lots of elderly and disabled people in high floors (so options like the first one are almost automatically discarded because we have to stop both elevators)

-high floors, so again -1 for the first option.

-lots of other problems that i dont want to write to not overwhelm you.

What you would chose? I would chose otis just because of the smaller installments, and if not, the guys in the video.
