Colley Elevators 7th Annual QEI continuing education training

Each year for the last 7 years Colley Elevator has been hosting inspectors from across the Chicago area as well as mechanics from Colley and other companies to attend QEI/Elevator code continuing education.

This year we again had Joe Donnelly – PE conduct the training. Joe D has had a pretty incredible career starting out by working for Westinghouse Elevator as a apprentice then field engineer moving to Lerch Bates to start his consulting career and now at Donnelly & Associates doing elevator consulting and training.  He has had experience working on the State of Illinois Board as the technical advisor and currently is the Chair of the City of Chicago code committee and helped bring the City from a 2001 code to 2016.

While the content is similar year to year [the code doesn’t change quickly] I always learn something different each session.  The group of inspectors and mechanics who come also bring their own experiences to the discussion which is always interesting.

This year we reviewed – City – State code update, 2010 & 2013 A17.1 major code update, 2016 A17.1 Part 2 code update, 2016 A17.1 Part 3 code update, A17.1 Part 6 code update, A17.1 part 8.6 code update, FEO service review, A17.3 code review, NEC code update, A117.1 class, A17.2 routine inspection review, A17.2 periodic test review, City of Chicago 2018 code A17.1, City of Chicago 2018 code A17.3

My notes – As I said, I’ve heard all of this before many times but it sinks in a little more each time and you always pick up a few items that you can use every day.

State of Illinois mandate

Fire service witnessing – We discussed the potential issue with coordination and staffing

            Braille – Recent ADA mandate in our elevator world

Chicago code modifications

           Pit sprinklers

Car top stations – pendant station – may be a future solution to inspection station placement

           Access switches – 12” away from door jamb – Big change to some designs

           Emergency exits with 14” x 14” space next to – Never paid much attention to this

Hoistway – 55-95 Degrees – Hoistway “safe environment for elevator equipment” temperature controlled – Always important

           Freight elevator – Push to stop switches

In/car stop switch during phase I stops the car – Change now that we have keyed stop switches

            Fire alarms needed in hoistways when these are in HW – applicable to MRLs

                        Motor control

                        Drive machine

                        Control space

Phone jacks in fixtures are only required when FD use communication center @ building – This is not a very popular item because our fire fighters use walkie talkies

           Expiration of batteries visible to batteries – No one does this but should

Smoke detectors – Limitations where the need to go on wall – Fire companies need to follow the code

           Sprinkler requirement – I always get tripped up here

Toe Guard – 60 to 75 degrees – I always forget this dimension

NEC

Isolation transformers – ML to controller to Iso to controller – not disconnect to Iso to controller – if wired this way – need additional disconnect

High voltage to low voltage – UL label – coming in controller

Fire alarm announciator is king for where lobby panel – chiefed by life safety company & AHJ – Life safety companies need to talk to AHJ before we start so we are both on the same page.

Take away – Our professional lives go so quickly day by day and we “know everything” but I think sometimes taking time to go through some additional training on things you know goes a long way.  We also picked up a lot of good information from one another.

Elevator cylinder replacement – Cylinder hole clause – Water

We do a lot of cylinder work at Colley Elevator and each project is a bit different from the next.  This is what some quick thinking, quick response and a total team effort looks like when something goes wrong on a cylinder replacement.

We got the car hung, piston out, cylinder out and had a 14” casing, some water but nothing unusual for cylinder replacement.  We needed to get around 41’ of clear hole, our cylinder was going to be 39’ 5” in the ground, then you need to add the PVC and we get around 40’+, lets shoot for 41’.

[Looks like a regular cylinder hole to me]

We had the debris removal truck come by and we got a call from the project team that the debris removal truck was already filled up an hour into it and they were ½ way down and there is a jet stream of water what looks like a fire hose spraying water at about 15’-20’.  One of our top notch project engineers jumped in his car to go work with the team.  We all assessed the situation, talked to our shop, got a 12” casing with no bottom and integral couplings[saves space with no lips] ordered.  Our top notch shop brought out 50’ of PVC within an hour, we barely got it fit in the hole and it went 30’, dropped the debris removal hose down again and put another 15’ of PVC on top as the PVC sank, 20 minutes later we had a clear 42’ hole.  Got on the horn and ordered a cylinder bag from Laird Plastics and it was here the next day.

[The pond in front of the building most likely was donating the water to our hole]

We were able to stop the water stream at the 15’-20’ from coming in our hole by creating a new barrier that allowed us to clear the sand, mud and rock out of the hole.  Once the water reached natural table level it stopped coming in the hole and the problem was solved.

[12" PVC fit like a glove]

Take away - This was a 100% team effort and one for the books.  We all have different experiences dealing with projects so the more heads you get involved the more ideas come up and the existing ideas get improved and this crisis was averted.  If everyone wasn’t moving as quick as we did this would have been a job for a well driller which means a significant expense and extra down time.  The elevator inspection is set for next week. Bravo to all involved.

Hydraulic elevator modernization – Homewood, IL - Dover Elevator

We recently where awarded a project with a construction firm to complete an institutions hydraulic elevator modernization through a GC.  Colley Elevator did not have the lowest price for the project on the initial bid, but, the GC and design group felt Colley was the best fit for the project and the attention it would require.

Existing elevator & project scope – The existing elevator was a Dover relay logic from the 1970.  The building wanted to move the machine room from the basement to the 3^rd floor so it would have a formal temperature-controlled machine room.  The specifications where written but a consultant and an architect was administering the project.   The building would get a new controller, power unit, pipe line, door operator & equipment, fixtures, hatch & car doors and new interior.

New equipment providers

Controllers – Smartrise Engineering

Power units – MEI

Door operators – GAL

Fixtures – Innovation Industries

Hatch & car door – Columbia Elevator

Cab interior – Summit Cabs

Machine room – The existing machine room was in a boiler/mechanical area in the basement of the building.  The room was extremely hot as it shared it with the boilers.  The new machine room would be located on the 3^rd floor in building’s maintenance shop.

[Old machine room location]

Hydraulic elevator controller – The original Dover relay logic control system would be replaced with a non-proprietary Smartrise Engineering elevator controller.

[Old Dover controller - panel 1 of 2]

[Old Dover controller - panel 2 of 2]

[New Smartrise Controller - only one panel]

Hydraulic elevator power unit – The elevator had a newer hydraulic power unit but it was decided on the design side to replace all major mechanical and electrical components.  We replaced a MEI tank with Maxton UC 4 valve from 2015 with a new MEI tank with Maxton UC4 valve.  We also utilized the Maxton shut off valves & isolation couplings for this project.

Door operators – The cars had all Dover equipment on them.  We replaced the Dover door operators with GAL MOVFRs and replaced all the Dover hatch equipment.

[Old Dover door equipment]

Elevator fixtures – All of the Dover hall and car push buttons where replaced with Innovation Industries fixtures.

[Old Dover fixtures]

[New Innovation car station]

[Old 1st floor hall station]

[New first floor hall station with position indicator above door]

Elevator car & hatch doors – The old car and hatch doors where replaced with new Columbia Elevator doors to give it a fresh look.

Elevator cab interior – The elevator’s cab interior was updated with a package from Summit Elevator Interiors.

[Old cab interior]

[New cab interior]

Work by others – There was a fairly extensive scope of work by others on this project that included new machine room, electrical, shunt, fire alarms, cab floor, hoistway protection[during the project]

We are happy the project turned out well, the building owner was great to work with, the design team was great to work with and the general contractor was great to work with.  Elevator has been running smooth with no shut downs and faculty and parents do not have to worry about the reliability any more.

Massive elevator hydraulic fluid contamination water

We have always had a challenge when we have water contaminate the hydraulic fluid in elevator systems.  It could be from a water pipe breaking in the machine room or the pit flooding and a rec pump, pumping water back into the reservoir.  What do you do?

There is a wonderful device from Gorman that filters hydraulic fluid and removes the water from the hydraulic fluid.  Typically when we have water contamination we remove as much hydraulic fluid as we can and replace it and put this machine on for 30-60 days and the contamination is gone, no problem we move on to the next building.

Recently we had a building where a pipe broke and we misjudged exactly how much water was in the hydraulic system.  The amount of water must have been so massive it pushed 40-60 gallons of oil out of the hydraulic system.  Water is heavier than oil so it will sink so and the water kept coming in, the elevator kept running, the hydraulic fluid was pushed out the top and down the floor drain with the other water and eventually most of the tank was probably water, and water was in the hydraulic line and cylinder.  What we found was that the water bonded with the oil and created a white liquid that would not separate with the water/oil machine running.

We ended up replacing the oil twice and changing the filter on the water/oil separator machine and finally got the results we wanted.  What we learned from the situation was we need to be a bit more careful when we have water enter an elevator’s hydraulic system. We assumed there was 10 gallons of water or less in the elevator system.  In reality it was more like 40-60 gallons of water, about 50% of the total volume in the hydraulic reservoir. 

Bottle #1- This is typical water/oil separation when I took some oil from our supply and pour water in it, clean separation.

Bottle #2 - Sample after we replaced the oil the first time and put the separator on.

Bottle #3 - Sample after we had the separator on for 60 days.

Bottle #4 - Sample after had replaced the oil the 2nd time and changed the separators filter and let it run for 30 more days.

What can happen with a water contaminated oil?  It will eventually rust out the elevator’s valve.  Rust in the valve will cause shut downs and the elevator may not level properly.

We had a very patient building who worked with us through the ultimate solution to their issue and we finally got an acceptable fluid composition.  I have been working in elevators for 23 years and have never seen such a massive amount of water enter an elevator hydraulic system.  The most unique part of this specific situation is the white liquid that was created by the bonding of the oil and water.  The samples have each been sitting out at least 30 days.
