End Of Life/Obsolete Elevator Equipment – TAC 20/TAC 22

 

This is big news for buildings with Thyssen Krupp/TKE or TK TAC 20 or TAC 22 controller platforms.  In a letter dated 1/6/25 sent to buildings with this elevator installed indicating the CPU board has been officially discontinued.  These are not old elevators, they where installed in the 2000’s and 2010’s

 

What’s the story?  Thyssen Krupp/TKE now TK is retiring their TAC 20 & TAC 22 product line.

Who this impacts – If you have a Thyssen Krupp/TKE/TK TAC 20 or TAC 22 control system you should begin putting money away for a control modernization.  There are still parts available, we have parts, but when they are gone, they are gone. 

Are parts still available? – Yes and no.  There are 3^rd party manufacturers that stock some of the boards.  There are a few elevator solid state board repair shops that will repair the boards.  The warning with any board repair is that while the intention is to be successful, sometimes board repairs are not successful or take a few tries.  If you don’t want these challenges, replace the elevator controller prior to going down this painful road. 

Is software available once your replace boards? – Yes and No.  We have ordered software for elevators and it has taken 4-8 weeks to get.  Why does this matter?  Sometimes when you are switching boards you will need updated software or the original software to load on the control board.

Take away – If you have one of these controllers in your building get a plan together with your elevator contractor.  See if they have replacement parts and how many.  When it rains it pours, be aware that there are a lot of these out there and if a few have issues at the same time and require spare parts, you are pulling from the same spare part pool which is finite.

State of Illinois Fire Marshal Elevator Safety Review Board Meeting 3/9/25 – Door Lock Monitoring DLM

 

The State of Illinois Fire Marshall Elevator Safety Review Board met on Thursday 3/6/25. The main item that was addressed was to adopt the new elevator code A17.1 2022. This code adoption has large implications on new/modernized elevators and even larger implications on existing elevators. The largest item is existing elevators and the requirement of door lock monitoring. THIS CODE HAS NOT BEEN 100% ADOPTED YET AND IS GOING TO SPRINGFIELD TO COMPLETE THE FULL ADOPTION PROCESS.

 

41 ILLINOIS ADMINISTRATIVE CODE 1000 1000.30 - TITLE 41: FIRE PROTECTION CHAPTER II: ELEVATOR SAFETY REVIEW BOARD - PART 1000

ILLINOIS ELEVATOR SAFETY RULES

iii. Modification: Door Lock Monitoring. System to Monitor and Prevent Automatic Operation of an Elevator with Faulty Door Contact Circuits.

a) Automatic passenger and freight elevators installed or permitted for installation prior to effective date of the adoption of ASME A17.1 (2022) shall comply with Section 2.26.5 by January 1, 2029.

b) Automatic passenger and freight elevators permitted for installation on or after the effective date of the adoption of ASME A17.1 (2022) shall comply with Section 2.26.5.


What does this mean for you? If you have an elevator that was installed prior to between 2000 to 2004, you most likely do not have door lock monitoring. This means the elevator will need to have it. If you do not have door lock monitoring you can get door lock monitoring 2 ways:

1. Replace the elevator controller – Replacing the elevator controller and door operator will ensure you have door lock monitoring and is the most reliable way to complete the requirement. This is also the most expensive way to get door lock monitoring because you will trigger other code requirements on the elevator and with the building. 

• Expense – High
• Reliability and chances of compliance - High

2. Install an auxiliary DLM panel on an existing controller– This is the quickest and least expensive option. Older elevator controllers and door operators are not recommended to have this completed because it may make your elevator system less reliable due to the additional devices that need to be added. You may also have issues with the wiring of a new door lock monitoring system to an elevator that has had wiring changes over the years (and may not have them documented correctly with wiring diagrams). Older elevators or elevators without accurate wiring diagrams will be challenging, if not impossible, to have a door lock monitoring system added.

• Expense – Lower
• Reliability and chances of compliance - Lower

There are other more typical code updates coming with A17.1 2022 which will have additional impact on new construction and modernization projects.

Moving forward - Code adoption will move to the Joint Committee on Administrative Rules (J-Car) next and then needs to get on the state agenda. Possible date for adoption would be around the third quarter. 

Does my elevator have door lock monitoring? Call your elevator maintenance provider and ask them. For buildings that need to prepare for a project, it will be expensive and you will have an elevator outage for a significant period of time, so start planning! January 2029 will come quick.

Elevator Picture Hall of Fame 2025 – Superbowl of Elevators

The Hall of Fame posts are typically some of the more popular blogs in the Colley blog history. We get to see a lot of elevators during the year on our initial visits for pricing or while engineering projects. Of the hundreds of elevators, and thousands of pictures, these are some of the gems we've seen this past year.

Try and fix I dare you - Not sure what this Wizard was thinking. The Wizard, a movie featuring Fred Savage, was one my childhood friend Robert and I watched a dozen times. It was a great promotional piece for Super Mario Brothers 3. In the 1980s when we got Mario Brothers 1, on the first level there was a place where you could jump past the finish line above the level and find the secret pass where you fell down into a cavern. You had the choice of three tubes to go down, but, you had to know how to get down the tubes[pushing the down button]. Well… My mom didn’t know how to go down the tubes and she was stuck in this area frequently. When she got stuck, my brother and I would wait for her game timer to go down to 10 and do the 10, 9, 8, 7… and start screaming each time she ran out of time. She probably really appreciated that. There are terminals in the box that could have been used.

 

Don’t turn on - It is hard to read the notes on the pieces of paper but they clearly say THIS IS A FRIDAY NIGHT FIX, PLEASE HELP ME WHEN YOU COME BACK.

 

Glass is half full -  It is an MCE greenboard controller.

Hit the showers - When I was in Junior High, the gym teachers used to make us all go in the showers after gym and they sat and watched us walk under the water, every day for 2 years. The towels they gave us were about what you see on the door restrictor. I wonder if my old Jr. High gym teachers live at this place.

 

Field innovation – I’ve never seen this one before. 

 

Tar pits – When I saw this picture and I was told the building owner rep wanted a new door operator all I could think of was “how did it get so bad?” Then I thought about Big Foot and while this foot print isn’t so big, if Big Foot ever did go in this pit we could totally find him because he would track this tar/oil substance all over the building and into the parking lot. I wonder if this person took his boot off before getting in his car to drive home or to the next place. That reminds me of when I was at the Cardinal's house and I got a big glob of grease on my boots and tracked it up the stairs. I had 3 Nuns watch me scrub the carpet with resolve. I think the guys who were actually doing the elevator work at the building where having a bit of fun having the boss scrub the 45 year old carpet and Nuns from a foreign land giving me constant feedback on my job progress. KEEP YOUR FEET CLEAN!

 

Pasta night – Maybe they didn’t have a smaller junction box to give them. Maybe they saved so much time reusing the junction box it was worth it. Maybe ¼ of the way into working with this junction box they thought this wasn’t a good idea.

 

Anyone going to say something? – The building owner found a good deal on smoke detectors. It so happens that Mike who lived in the building was a fire alarm installer and he did it himself during the nights and weekends. Last year Mike was an arborist and was cutting down trees. The year before that he worked as a spray foam insulation specialist. Hire a professional company, please.

Wizard of OZ –. My daughter is obsessed with Wicked the movie. The first of 2 movies came out in November 24’, she loves it, she had her birthday party at the movie. She has a Wicked shirt, Wicked sweatpants and a Wicked sweatshirt. The 2nd of the 2 movies will come out November 25’ and she is very excited to see the 2nd movie. Her and her friend go on YouTube and try and find the 2nd movie early, they haven’t found it yet. I’m not going to tell her but I have some screen shots from the new movie. What she doesn’t know is that before The Wizard went to OZ he was an elevator maintenance person and they spend about a ½ hour of the movie going through his day and we see some of his car tops and pits. DON’T LOOK BEHIND THE CURTAIN.

Disclaimer – We see hundreds and thousands of pictures over the course of a year. While we don’t see as many great pictures of maintained elevators, we do see them, which is fantastic. We have a lot of very dedicated and talented elevator people in our area. The reason we don’t see a lot of buildings getting great elevator service is because they are happy with their mechanic and the mechanic is probably cleaning and taking care of the building. Those buildings are not calling us to get pricing for elevator work because they are being taken care of. Be the great mechanic or helper, don’t be these people. We should all take the time and care we would like to have people who work in our homes to have. Do great things! We have great jobs! We have a great industry! If you are doing great, Keep it up. If you need to improve, no other time than now to start! Lets do it!

Cold Weather and Elevators - Deep Freeze 2025

We have had pretty warm weather in the Chicago area up until recently, now it is cooooolllldddd!

Symptoms

              Elevator runs sluggishly

              Elevator doesn’t level properly

              Doors move slowly and are bumpy

              Potential outcomes

              People get stuck or trapped in the elevator

              Trips and falls

              Elevator will not work to service the building

According to the NEII vertical transportation standard, the temperature of your elevator machine room should be 55 degrees to 80 degrees.  Computer manufacturers recommend an ambient temperature of 60 to 90 degrees.

The temperatures that hydraulic elevators fluid should be is:

            Operating temperature  - 80 to 150 degrees Fahrenheit

Source - Maxton Valve[www.maxtonvalve.com] - Maxton valve is one of the largest valve suppliers in North America.

Oil composition when it gets cold – When hydraulic elevator fluid gets cold it becomes thicker or has a higher viscosity.  Higher viscosity means sluggish leveling which means potential trip and falls or shut downs. 

Viscosity definition - The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stressor tensile stress. For liquids, it corresponds to the informal concept of "thickness". For example, honey has a much higher viscosity than water.

How does this translate to your elevator – In our Chicago area environment we use a certain hydraulic fluid that offers more flexibility between hot and cold environment because of our seasons in the Chicago area.  Due to significant swings in temperature in our environment when it is very cold the oil gets thicker and the valve and elevator system will not operate correctly causing a potential issue with leveling or entrapment.  The reverse occurs when it gets very hot and the oil gets very hot.  Both scenarios cause safety issues for the elevator riders.  If we always had cold or warm temperatures we could use a different hydraulic fluid that would be more appropriate for a hot or cold environment.  But! We live in Chicago.

What not to do – As a building owner it is very important to have your elevator running.  Some building owners take it upon themselves to improvise to get their elevators running on cold days with space heaters.  While the installation of space heaters is a short term solution, it isn't a safe long term solution as you will see space heaters in non-occupied machinery spaces that can malfunction causing smoke and fire hazards.  The space heaters also can overload your electrical circuits causing your breakers to trip.  The electricity costs to run multiple heaters in one year would probably be significantly more than the installation of an elevator tank heater.

 

[This building owner was resourceful putting a heater on the valve]

[Two heaters on one elevator power unit]

 

[One heater in the elevator pit]

Recommended solution – use a tank heater.  Pay an elevator company to install a tank heater on the elevator with an on/off switch.  This is a safe alternative to space heaters. But!  Turn the tank heater off in the summer or you will smoke your oil and burn it, if you burn your oil you will have different issues.

Take away – If you are having winter issues, talk to your elevator company.  If you are not getting the right answers, call Colley Elevator.  I went to a building for a nuisance issue[not a Colley maintenance account], they described what was occurring, without even walking in the elevator room I told them it was cold oil, they told me they had a space heater in the machine room, when we looked, they did have a space heater and it hadn’t worked all season.  The valve was ice cold.  I’m sure they will go get a new one and when it is in the machine room their inconsistencies will go away.

Salt – When we start getting cold and start having snow we use a lot of salt on the side walk.  That salt gets on our feet and comes in the building.  Have someone vacuum out the door sills because salt loves to live there and we will come out for a overtime call and charge you a lot of money for a few pieces of salt.  If you can do prevention, that is the best, but we are also always available.

Year in Reflection - Colley Elevator Blog - 2024 review

Welcome 2025!  This is our 11th year doing the blog; our first post was 2/28/14.  We had a great 2024 at Colley Elevator so this is a quick recap of our year as we move forward to the next.  For me it is a great way to see where we came from and where we want to go. I’m lucky to have such great people around as we enter our 117th year of being an independent elevator contractor.  Thank you to everyone that was part of our 2024 year!

Annual reflection – This year we saw our maintenance portfolio grow from 2350 to over 2522 elevators.  We had some bigger portfolios come over but a majority of our new customers are buildings with one or two elevators.  We have switched our main hydro controller to Alpha Elevator with still a good amount of Smartrise and using MCE as our main traction elevator controller.   We have had major headaches from GAL with shipping and have had to start ordering bulk from their local office.   This has been a large learning curve for us.  In total we probably bought 110 door operators, 80+ fixture packages, 60+ power units and a few packages[MEI & Canton].  We purchased 30-40 cylinders for ITI & EECO along with some from Custom and Hydraulic Elevator. 

Colley Cares, our philanthropic outreach, gave out over $12,000 to philanthropic organizations ranging from substance abuse to food depositories.  The Colley team came together to help out Toys for Tots this fall/winter with a truck load of gifts and food to help out those in need. We work with incredible people who made this all happen and our average employment is about 10 years. 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!  In 2024 Elevator World let us participate in their Annual Ellie “best in area” contest and we brought home the 2024 Best Contractor of the North[making it our 4th win].

Elevator resolution – This year I would like to take the opportunity to encourage everyone to go past their ceiling, giving the tools and time to do great things in their particular position.  Industrywide there is too much cannibalism for short term gains which diminishes our jobs and how we are looked at.

FAID inspections– The FAID inspection have been a big challenge for everyone. We are doing a great job.  We have gotten a pretty good system going but have a lot to work on in 2025.  If you don’t have your FAID done yet on your hydro, lets get it set up for 2025!

2024 projects/relationships – In 2024 we  have seen an up tick on projects and have had some project flow challenges like any elevator company, but we have bottle necks that we've been working out.  We are working with a lot of portfolios as well as a lot of single elevator buildings. 

Competitive market – We have seen a decline on our OEM’s maintenance programs. I call it NO LIFE GUARD ON DUTY – NO MAINTENANCE BEING PERFORMED.   We have doubled down on our Pits and Car Tops program by encouraging our maintenance mechanics to do great things with the time they have at the building.  We have also had the opportunity to work with more elevator consultants this year and working with more buildings on Turn Key solutions. 

Suppliers – We have some incredible suppliers that deliver every day, all day, all year.  Thank you!  On the other hand we have seen some of our historically great suppliers do incredibly terrible things trying to implement corporate modeling, hiring marketing clowns and implement new software programs.  A message for some of our suppliers who have forgotten what made the companies they work for great, do better! You aren't going to value engineer, restructure or sell your way to more profit or a to a better company. You will trip, fall and ruin good names and legacies. Don't forget your roots and where you came from. 

Thank you for everyone who took the time to read the blog.  Work safe, getting better, do great things and make our industry a better place for everyone.
