3D Door Scans – New Elevator Code A17.1 2019 – State Of Illinois

As of 5/25/21 the State of Illinois adopted A17.1 2019 which means we require all sorts of new gizmos including a new style 3D door scan.  This means 2 things; you get a safer elevator and it will be more expensive. 

In the State of Illinois we are required to install 3D door scans when:

        1. We replace a safe edge or electric eye

        2. We modernize an elevator system 

        3. We install a new construction elevator

In the State of Illinois we are not required to install a 3D door scan when:

        1. We replace it for a like door scan

How does it work? Detection of approaching objects

Detection of approaching objects/persons is now mandatory. The aim is to ensure that approaching objects trigger the doors to open, thus reducing chances of being hit by the closing elevator doors. The code states that an object of  an 8" diameter and 40" height will need to be detected at an approaching speed of up to 3 ft/s within a defined detection zone.

The design requirements within the code call out the detection of ‘ultra-flat matte black’ and ‘glossy white’ color targets. As matte black surfaces absorb infrared (IR), conventional 3D detection solutions based on IR technology will be unable to detect the target.

[detection objects required for testing]

The detection zone, wherein objects must be detected when moving towards the doors, is described as between 20” and 9” from the landing side face of the hoist way door and 9” ahead of the leading edges of the doors. This area will decrease in size as the doors begin to shut. Once the leading edge of the doors are within 18” of the fully closed position, the detection device is permitted to become inoperative, unless there is a 2D trigger before the doors are fully closed.

Rendering inoperative of a 3D detection means

The rendering inoperative requirement for 3D detection focuses on 2 things:

    1. Once the leading edge of the doors are 18” from the closing point (i.e. the other door or door jamb) the 3D detection device is permitted to become temporarily inoperative. For reference the 2D detection is required to stay active until 0.75” from the door / door jamb.

    2. The second point relates to how long after a trigger the 3D detector is supposed to stay active. After the first 3D trigger the detection device is required to stay active for 20 seconds. Once the 20 seconds is over, the 3D detector is permitted to be made temporarily inoperative and the doors will begin to shut unless there is a trigger in the 2D detection zone whereby the 20 second count will begin again.

What does a 3D door scan do differently than a 2D door scan?  The traditional 2D door scan rides on the elevator and will detect an object or person when it breaks the threshold of the elevator's car door.  The intent of the code change is to catch a person or object so it doesn't get caught between the car door and hatch door.  You know, when you run to catch an elevator and put your hand in the door way hoping the door reopens?  We want to reopen the door so people's hands aren't getting caught in the hatch door if they don't break the car door beam.

What if I installed a 3D door scan years ago, do I comply?  Probably not because that generation of door scans didn’t work very well.  Some had cool light up colors, some had some promises, but most didn’t work to today’s code requirements. 

Who sells 3D door scans?  Lots of great vendors sell solutions for 3D.  If I missed one, let me know so I can put a link up.

Colley Cares - Chicago Land Elevator Company Gives Back!

 

Last year we committed to extend some of our charitable outreach. The more we sell, the more we donate. As a group we targeted 5 organizations to support in the 4th quarter of 2021.   We will also continue to support the organizations we have supported for many years. Colley Elevator will be donating an additional $1,900.00 amongst the following 5 great causes.  We have given over $12,000.00 in 2021 to our 2021 line up.  I have included how we got to know each of the organizations and why they mean something to us. Get to know them and if you feel so inclined, give them a few bucks. 

 Pillars Community Health website

Pillars Community Health – A healthcare organization that is committed to meeting the changing health and social needs of the western suburban residents.

Colley Elevator has been servicing buildings for Community Nurses out of La Grange, IL for the last 40-50+ years. Pillars and Community Nurses merged to form Pillars Community Health. Pillars Community Healthy is a phenomenal organization that you should get to know! I have a deep appreciation for everything they do day to day!

 

Ray Graham Association website

Ray Graham Association – Founded in 1950, Ray Graham Association serves nearly 2,000 people with disabilities and employ about nearly 350 people. Ray Graham enriches lives by empowering those we support and those who care for them to reach, grow, and achieve. Thank you for being a part of this life-saving and life-giving mission.

I got a phone call from a person who I dealt with at a facility for many years and he had a new gig at Ray Graham and wanted us to take a look at his elevator.  I walked in and saw the wonderful work the people at Ray Graham are doing and learned about their organization.  Before I even left the building I thought of them as one of our Colley Cares causes.  RG has a facility right by my house and I ride my bike by it with my kids frequently, now I know what they do.  Get to know them!

NEDSRA website

NEDSRA – Northeast DuPage Special Recreation Association improves the quality of life for thousands of people with disabilities each year by providing them with a variety of recreational and social programs. The programs are offered in partnership with eight park districts and three village recreation departments.

We had a phone call for an opportunity that was nearby. When we stopped in, we talked about what the organization does. In the end, we helped them out with their elevator and are now their service provider. It's been a pleasure getting to know this group which is doing wonderful things. One of our coworker’s family members has had great experiences with the service offerings that NEDSRA provides.

                                

Chicago Food Bank website

Greater Chicago Food Pantry – A united community effort working to bring food, dignity and hope to our Cook County neighbors.

Something we may take for granted is having a meal on the table. Some people cannot take that for granted and this is one of the organizations that is there to help them in their time of need. No one should go to bed hungry, go to school hungry or have to worry where their next meal is coming from. This is one of the organizations that Colley fundraised for last year and donated a few thousand dollars to.

Hydraulic Freight Elevator Modernization – Evanston, IL

We recently turned over the first of a multiple car modernization that was the heart and soul of the building, the freight car.  This elevator is in charge of food service, materials, construction, storage and all other heavy lifting.  Since freight elevators are a niche within a niche industry, I am always pretty stoked to get a chance to work on them and work with the different vendors that are only freight elevator suppliers.  After we completed and visited the building to do the final equipment review, I saw this freight car being used and abused nonstop by the building, food service, contractors and anyone in-between to get everything where it needed to go and it didn’t skip a beat.  Great work Colley field teams!

Existing elevator & project scope – The old elevator system was an Otis Elevator from 1962 with all original components; Otis Elevator controls, Otis Elevator freight doors, Otis Elevator hydraulic power unit.

New equipment providers

Controllers – Motion Control Engineering

Door operators – Peelle Doors wireless

Fixtures – Innovation Industries

Power unit – Quality Elevator w/Maxton UC4 control valve

Elevator controllers – The existing elevator controller was an Otis Elevator hydraulic controller from 1962.  The new elevator controller is a Motion Control Engineering hydraulic elevator controller.

[New MCE 2000 hydraulic elevator controller]

Freight door equipment – We replaced the existing Otis Elevator automatic freight doors with Peelle Company freight door equipment.

Elevator fixtures – The old Otis Elevator hall and car stations where removed and we installed Innovation Industries fixtures.  We also installed an additional car station for the building as it is helpful to have 2 car stations on this walk through elevator. This helps multiple people, loading multiple loads at the same time, get in the elevator.

Experience – This elevator modernization's first look was in April 20’ when COVID was unknown and scary. We had a walk through with 15+ people in a sensitive building and a bunch of contractors, GC’s and building owners.  We were fortunate enough to have the opportunity to work with the building on this elevator, which will be the first of 5 modernizations over the next few years.  Over the last two years, we have worked with 2 GCs, an elevator consultant, building owner, and multiple other trades before we even began the project.  With all of these other people orbiting the project, some helpful some not so much, and COVID surrounding us we delivered a great end product for the building owner.

Team work– The sales person and the project team who finishes typically get the glory on a project.  In between the initial contract sale and the final acceptance are many other people who work on the project to make it successful.  From the truck driver to the engineer to the billing department to the assistance when needed, 14 Colley Elevator employees where involved in the project and we had tremendous team work on it.  Thank you everyone - without you we would not have had such a successful delivery!

Cold Weather Elevator – How Does Cold Weather Affect My Elevator

We have had pretty warm weather in the Chicago area up until recently, now it is cooooolllldddd!   What happens to your elevator when it gets cold?  Good question. 

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

Trip 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 

Operating temperature  - 100 to 130 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.  

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. 

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.
