Elevator Preventative Maintenance – How often should my elevator technician come by?


Back ground - We have been getting a tremendous amount of calls for maintenance proposals and more than ½ the time the reason is that the incumbent company doesn’t even show up, but, the building is still being billed.  I only go on a small percent of the walk throughs but I get to see all the pictures and when we are only showing up to take service calls we are deferring maintenance and putting the building owner’s elevator equipment in a compromised position.




What’s the big deal? Elevator maintenance is important because the elevator is most likely the most complicated piece of equipment in the building.  We have hundreds of moving parts on an elevator and it is very important that you have a qualified and competent service technician reviewing your equipment on a regular basis.  If no one is looking at the equipment, cleaning the equipment, etc your issues will snowball to having a elevator that looks like the surface of the moon because no one has cleaned it or having an electrical or mechanical failure because we are not checking the critical components of your elevator system[start contacts, motor brushes, suspension cables, etc].  You also are required to have functioning emergency phones, lights, fireman’s recall, etc that should be checked on a regular basis to ensure they function correctly in the event of an emergency.

How often should someone come?  This is a good question.  Every elevator is different and should be looked at differently.  At Colley we sit down after we visit a building and ask questions like; What kind of building is it?  What is the traffic like?  What is the environment?  Who is using it? Etc.   Ultimately we can give our recommendation for how frequent someone should visit but if the elevator contractor recommends X and the building owner only wants to pay for X minus Y then the  choice for an elevator contractor is to give it to them or walk away from the opportunity.   Make sure when you talk to a potential elevator maintenance company you ask them “why are you recommending quarterly/monthly/bi monthly, semi annual  visits”?  What are my building’s needs.  

Monthly to Quarterly – For many generations the elevator technician has been going to most elevators on a monthly basis.  This has been changing over the last 10 years.  Now we go quarterly or “systematically”.  “Systematically” typically means as little as possible. This goes back to the conversation you have with your current or potential elevator contractor and finding out why they come to your building when they do and if it makes sense for your elevator(s).  The biggest issue with no going to buildings on a monthly basis is who is going to exercise fireman’s recall Phase I & II, it is required to be checked monthly in our elevator code and is a State of Illinois/City of Chicago requirement.

OEMs – The Otis, Schindlers, Kone, Thyssen Krupp’s of the world are very busy and in our area do not have the man power to go to the maintenance stops on a regular basis.  We are seeing deferred maintenance.  We are hearing buildings who call in at 8am and get “if you want someone out there today, it will be after hours at $900.00 an hour”.   There are a lot of great elevator mechanics at OEMs, the issue is they don’t have the hours in the day to complete the required work load.  Some of this is due to looking for short term profits[you remove a few guys here or there and the bottom line looks better], some of this is due to a lack of elevator mechanics available.

Remote monitoring – I am not yet a believer in remote monitoring yet.  I’m sure the different remote monitoring devices have great capabilities to capture data 
There is something to be said about having trained eyes and ears riding your elevator to identify if something doesn’t feel right.  Remote monitoring is a wonderful selling point but I’m not sure how great it works in practice other than allows the company implementing it to not send an elevator mechanic to the building.  I have not seen an elevator monitoring device from an OEM that will tell you if your elevator pit is filled with water or you have a pipe that is dripping on your controller in the machine room that is about to damage your solid state circuit boards. If I’m wrong, please let me know.

[Not sure any remote monitoring system will pick this up]

Take away – Preventative maintenance is required on anything with moving or building critical parts; furnace/AC, alarm systems, sprinklers, elevators, etc.   Your elevator is a huge capital investment and the building’s users rely on it to get around in the building.  Educate yourself on what you are getting from your elevator contractor and it should make sense to you as an building manager, building owner and elevator contractor.  We collectively need to be on the same page on what type of elevator maintenance your building requires.

Colley Elevator end of Year Party – K1/Cybersport – Addison, IL

Who thought Whirly Ball/Cybersport would be so much fun?  Last Saturday we had our annual end of year party a Cybersport K1 Racing.   We had over 60 people brave the crummy weather to come together to start our 112th year as an Independent Elevator Contractor.  We had 437 years of collective Colley Elevator experiencing in attendance. 


It was wonderful to see our new faces and even better to see some of the legends who were building the foundation for us long before some of us knew what an elevator was.  We had a few 5 and 10 year anniversaries and got to say thank you to some of our long time employees who keep us together.  Every year when going through anniversaries and years worked it is amazing to see how long we have been together and the memories we create.

It is always great to see everyone get together outside of work and see who we spend the other ½ of our life with.  We have a deep appreciation for everyone who work with us but a deeper appreciation for the people at home who have to listen to how our days go.

We had surprisingly great food at the facility and had a raffle where 1/2 of the people walked away with something.  Everyone did get to leave with a Colley Elevator Yeti.



The games were competitive.  We had some shining stars and some black holes, but all of it was all fun!

[Many legendary battles took place on this court]

It takes a great group of people to keep this 112 year old company going.  I have said and will keep saying, It takes a lot of people from the first phone call to the final inspection or repair for us to be successful. I am proud to part of the team and that I get the opportunity to work with everyone here.   This is the group who won the 2019 Ellie!  Thank you to everyone!

Hydraulic Elevator Modernization – Montgomery MiProm – Park Ridge, IL


In May of 2002 I made my first sales visit to this building in Park Ridge, IL.  Years later we ended up doing a modernization on 3 of the elevators and they left one alone as it was newer than their 1960’s equipment that was in the old part of the building.  While newer equipment it was Montgomery Elevator Miprom equipment which isn’t always everyone’s favorite to work on.


Existing elevator & project scope – A new owner bought the building and was doing capital improvements and the non-modernized elevator had a habit of shutting down on the weekends.  This piece of conveyance equipment was critical in their building traffic pattern and could not have shut downs.  We made a recommendation to replace this piece of equipment for two reasons; 1st was the critical nature of this elevator to the building and 2nd was the amount of technicians who are proficient in Montgomery equipment will be fewer and fewer as the years go by due to the retirement of domain knowledge.  The new owners agreed and wanted a completed mechanical and electrical modernization.  This was completed on 12 hour days and delivered early back to the building.

New equipment providers

Controllers – Smartrise Engineering
Power units – MEI
Door operators – GAL
Fixtures – Innovation Industries

Elevator machine room– With updated equipment, painted machine room floor and new electrical makes it look a lot better!

Door operators – The elevator had MAC operator and equipment.  We replaced the operator with a GAL MOVFR and retained the MAC hatch equipment was replaced.

Elevator fixtures – The old Montgomery fixtures went away and new Innovation flush mount fixtures to meet ADA and elevator code requirements were installed.  I was pretty excited to see how the main landing turned out with the digital PI to replace the multi light on the right hand side of the door frame.

Take away – With how important this elevator was to the building the modernization was long overdue.  Our project team nailed it and brought it in early.  Another great team effort from signing of contract to engineering to delivery of equipment, project support and finally field personnel execution.  We also had some help from our Park Ridge Elevator Inspector who made it out there when we requested it.  Thank you to everyone involved.

Year in Reflection – Colley Elevator blog – 2019 Elevator Blog


What a year!  2019 winds down and we begin reflecting on the year and the decade. As Colley Elevator enters our 112 year as an independent elevator contractor we reflect on a few things to tie up the end of the year.

Annual reflection – This year we saw our maintenance portfolio grow from 1500 to 1650 elevators under contract.  This year we have ordered/installed 55 Smartrise controllers, a handful of MCE product and a ton of cylinders, power units and a few machines.  In 2019 Colley won Elevator World’s Ellie for Best Contractor in the North. We have a great team over at Colley from the person who answers the phone to the elevator technician who executes and everyone in-between.  I’m proud to work side by side with everyone here and that we have a culture of openness at Colley that helps get everyone done at a high level! Thank you to our coworkers, customers & suppliers for being great!

Decade reflection – Think about what was going on in 2010, as an elevator industry we started to feel the recession in the Elevator Industry.  Those days may be behind us but should not be forgotten.  A lot of people lost their jobs, and 401ks, plans for the future changed.  Right now the economies fire is burning hot, which is great, but what goes up will come down.  

Blog reflection – 47 posts in 2019[that is a lot of words, pictures and time], over 30,000 views, over 104,000 views in the blog’s history.  We did a really cool feature on non proprietary controllers feature some of the top brands.  This year I hope to do a few more mini features with freight doors and some other niche items.  With Tom Syberts retirement from Elevator Radio Show it makes us the longest running weekly social media source.  I loved the Elevator Radio show!  Thank you Tom for all the years of hard work!

Elevator electrical problems - Elevator motor damage


The motor is one of the most vulnerable parts of your elevator system to power issues.  From time to time we have premature motor issues which is difficult to explain and we attribute it to prolonged wear due to power issues.  We did some quick research for reference.

Here are some issues that will prematurely wear your motor

1.    Under/over voltage
a.    Under voltage - Can come from heavy use from your electrical grid/building
b.    Over voltage – When power grid doesn’t respond fast enough to shifting loads or lightening strike.
2.    Phase Loss/reversal  
a.    Can occur from lighting strike, power line issue, blown fuse, wiring error or contactor failure
3.    Voltage imbalance
a.    Contactor fails
b.    Tin can transformer fails and is replaced with a new one
c.    New load is added to one phase of facilities power system

2% imbalance = 8% temperature rise in motor windings
3% imbalance = 18% temperature rise in motor windings
As imbalance grows worse the temperature sky rockets
The higher the temperature the sooner the insulation on the motor windings will fail
NEMA[National Electrical Manufacturers Association] recommends less than 1% imbalance

When I am engineering elevator modernization projects we have started measuring each leg along with leg to leg.  It is rare that we are within the 1% NEMA recommendation on most of the buildings I go to.

What happens to your motor?  All these zips, zaps and drains will take a toll on the motor and lead to premature motor failure.  

What is the solution?

Add a phase monitor – A phase monitor can be installed for less than $1,000.00 and will protect your motor from many of the electrical issues listed above.  There are very simple phase monitors that will turn the elevator off when a power issue is detected. There are also phase monitors that will trap information so you have it and you can use it to pin point electrical issues and you can develop potential solutions.

[This device of a similar device is what we find on most older elevator systems with phase protection - it works great but you get limited information when it detects power problems]

[This device not only tracks phases but it traps a lot of information with time stamps - for a few more dollars you will get a lot more information]

Add a soft start motor starter – This is a device that will not only smooth out your electrical curve but also has phase protection built in.  The soft start will also increase your ride quality when replacing a mechanical motor starter. This device can be installed for $2,500.00 to $5,000.00 dependent on your VAC, HP and where it will fit in the elevator control system. 


Take away – Electrical issues are a buzz word in our industry because most of our issues are attributed to what the power the building supplies the elevator system.  Take a peek at a picture of a very old mercury switch from 50+ years ago that was installed to protect phase reversal, this is an age old problem.  If you are having issues, identify them and address them with your elevator contractor.  There are many tools out there that can help you quickly resolve power issues.  While we are talking about motors in this post, your elevator’s control system will also have significant issues if we do not supply it with the correct power.

[Left is newer phase protection - Right is very old phase protection]

Maxton valve no longer to repair or service valves over 20 years old



Starting January 1, 2020 Maxton will no longer maintain repair or VEP services for their elevator control valves beyond the age of 20 years rolling forward.  

The details are as follows:
·         Effective 1/1/2020
·         All Maxton valves manufactured prior to 2000, requiring replacement, will be "New only"
·         All parts used exclusively on said valves above will no longer be available.  
·         Rolling forward each calendar year maintaining 20-year range
·         2-year warranty period still applies for rebuilt & VEP valves prior to this announcement

This decision comes from a continuous decrease in market demand for older valves versus buying new.  Additionally, this progression gave way to slower inventory turns and increasing costs to maintain these programs.  After looking at the data further Maxton determined that valves over 20 years of age saw the sharpest decline and the line was drawn.


What is the VEP? The VEP or Valve Exchange Program is when you send a valve in and you get a repaired valve sent back to you.  Maxton then repairs your valve and will exchange that with someone else who sends theirs in, in the future.

What does this mean? Maxton valve is no longer going to do valve exchanges for 20+ year old valves or repair valves that are 20+ years old. 
           
i.e. The valve pictured was manufactured in 1985 and was sent back for repair in 1997.  If this valve was sent back for repair it would be retired and wouldn’t be a candidate for the VEP.


Can I still get technical support? Yes we can still get technical support for your 20+ year old valve but the reality is that there may be a strong recommendation to replace the valve if it is over 15-20 years old which has listed as the useful life of their valves.

How long should a valve last? A valve can last a very long time.  Maxton recommends replacing them every 15-20 years.  Depending on your environment, usage, oil contaminants and other variables it could require replacement sooner.
