Significant Code Changes that will Affect Your Elevators!

By: D&D Elevator

For reasons of safety and code compliance, property owners and managers should be aware that there are requirements that must be adhered to.

First up is regarding Elevator Door Lock Monitoring. The New York City Department of Buildings has announced that – by January 1, 2020 – all "automatic passenger and freight elevators must provide a system to monitor and prevent automatic operation with faulty door contact circuits."

Example of Door Lock MonitorElevator Door Lock Monitoring

The code is a requirement of Appendix K3, Rule 3.10.2, stating that the car doors must be monitored to prevent the following two issues:

  1. To prevent operation of the car if the car door is not closed, regardless of whether the car-door contact and interlock contact circuits are open or closed (excluding the access switch operation and inspection operation)
  2. To prevent power closing of the doors if the door is open and the car door contact circuit is closed or bypassed, or if the interlock circuit is closed (excluding during Firefighters' Service Phase II). Primarily, this determines if jumpers or other means of bypassing normal operation are being used

Elevators installed or modernized prior to July 1, 2009 will require a software and possibly a hardware update. Controllers installed or modernized after July 1, 2009 may already be partially compliant and may require installation of additional hardware or software – this will need to be confirmed by the elevator contractor. Elevators installed or modernized after January 2, 2015 may be equipped to be made fully compliant but, may need hardware or software installed. This also should be confirmed by the elevator contractor. If the controller cannot be adapted with the hardware or software upgrades, a modernization may be required. All modifications and/or software changes to the controller will require filing with the New York City Department of Buildings, and inspection and testing upon completion.

Further ahead, by 2027, Rope Grippers will be required by the NYC Building Code 2.19.2 and 2.8.4.1 Appendix K. Elevators without them will be considered non-compliant. Such devices – developed to safeguard passengers by stopping an elevator in case of a mechanical and/or electrical failure.

Rope Grippers will be required by the NYC Building Code 2.19.2 and 2.8.4.1 Appendix K. Elevators without them will be considered non-compliant. Such a device – developed to safeguard passengers by stopping an elevator in case of a mechanical and/or electrical failure – must be installed on all elevators by 2027. Rope grippers detect emergency situations, including if a car leaves a floor with the door open. They provide over-speed detection and unintended car movement with the door open when caused by brake, control or drive failure.

Addressing the Skilled Labor Shortage: D&D Elevator to open NYC-area Training Center for Elevator Technicians

By: D&D Elevator

D&D Training CenterOne of the primary issues facing U.S. industry today – across virtually all the manual labor trades, and particularly in construction – is an ongoing shortage of trained technicians. In the face of this skilled labor shortage, construction contractors across the U.S. are being forced into the uncomfortable position of having to turn down work. A recent Wall Street Journal survey revealed that more than 33% of the survey’s respondents needed to do so to maintain their project volume, a particular problem on the coasts and in regions recently affected by catastrophic weather events.

In the currently-bustling economic environment, there is no shortage of jobs in construction, but rather of skilled workers to fill them. Around the U.S., this is being strongly felt in the elevator industry, where steadily-growing building construction has created increasing demand for technicians to install, service and maintain new and existing systems. More and more one hears, “we need more trained technicians, but there’s no one available to hire.” Many firms are reporting that this is their greatest single challenge and that they are expecting such conditions to escalate in the months and years ahead. Some are offering increased compensation and benefits to attract the additional skilled labor they need, but to little or no avail.

According to Bob Schaeffer, CEO and President of Elmsford NY-based D&D Elevator Maintenance, the solution is “training, training, training,” and D&D has a plan underway to help.

An elevator industry veteran, Schaeffer has throughout his career been a strong advocate for education. Among his many accreditations, he served as board president of the National Association of Elevator Contractors (NAEC) and, as Education Chairman, was instrumental in creating the Certified Elevator Technician (CET™) certification. This nationally-recognized certificate program provides the elevator industry with the means of obtaining and verifying knowledge and experience requirements related to compliance with industry codes, elevator and escalator specific technical theory, components, and competencies.

For its own company, D&D Elevator has been delivering apprenticeship training for over 15 years with great success. Explains Schaeffer: “To allow us to grow at a reasonable pace, our goal was to make sure we always had enough skilled workers, while maintaining and enhancing our existing workforce. More recently, we have seen a dynamic change in the workforce. Retirees have outpaced new apprentices and rather than deal with the rigors of daily maintenance, repairs, modernizations and the installation of elevators, many qualified technicians have opted to become inspectors and third-party witnesses. Our industry urgently needs a young, skilled labor force to come in behind them.”

To address this need, D&D is working on expanding the training model to other elevator companies nationwide that subscribe to the common goal of using only educated and safety-trained skilled labor. When D&D began asking other companies if they had any interest in this, the answer was a resounding ‘if you build it, we will come.’ Accordingly, D&D has begun the process of building a 2,500-sq-ft Elevator Learning Center in Yonkers, NY, minutes north of New York City, anticipated to open Spring 2018. In keeping with the objective of developing an innovative education model that other companies would find valuable – while ensuring that the educational content is proven and accepted – all classes are being taught by highly-experienced and certified instructors.

According to Schaeffer, the overarching objective of the Center is to allow for other companies to train at its facility, either through its approved educational delivery system, or a process created through contractor related organizations. The Center’s services will include certified testing, proctoring and graduate placement services for entities that provide apprenticeship and re-certification. Working with Human Resource professionals, it is planning to add personal attribute and ethics training to help create well-rounded candidates who understand the importance of communication, quality and professionalism. Preliminary discussions are underway with school districts to include an elevator technician pilot program in trade schools at the high school level, to prepare students for apprenticeship training.

To provide actual hands-on, “real-life” training for students, the Center is receiving equipment from many companies in our industry, including Titan, Hollister-Whitney, Columbia Elevator, Delaware Elevator, AFD Industries, Innovation Industries, GAL, ESI, SmartRise and others; we are most grateful for their generous contributions to this mission.

Concludes Schaeffer: “We see this approach as a solution to the shortage of skilled labor – to help build a body of educated, trained, skilled, responsible workers for our industry, who can make an extremely good living while serving a pressing societal need.”

As Elevator Parts Reach OBSOLESCENCE

By: D&D Elevator

What You Need To Know…

Time flies and a significant percentage of elevators in the field today are aging to the point of obsolescence, with many systems and components in need of upgrade. While property managers and building owners may recognize the need to rethink their elevator equipment, budget and timing may be factors for some in implementing a full modernization all at once. At the least, consideration should be given to certain components of the elevator system, installed 20 to 30 years ago, which have outlived their useful life, or which have been rendered obsolete by technology advancements and updated code requirements.

For example, as was covered in a previous blog in this space, if a building today is operating hydraulic elevators with Single-Bottom-Cylinders installed prior to 1972, this stands in violation of various state and city codes, as well as the requirements of ASME A 17.1-2000. For several years now, code requirements have called for the use of Double Bottom Cylinders and the replacement of older single bottom installations, which should be upgraded as soon as possible. As also previously covered here, old controller systems – including ones made by major manufacturers such as Staley, AB SEE, Otis, Westinghouse, Dover, Armor and others – may require updating. Aside from conforming to code requirements, updating controllers can provide many other benefits, including faster response time, increased ride comfort and enhanced energy efficiency.

Old mechanical starters, making for bumpy rides, can now be replaced by newer “soft starters.” Upgrading door equipment, by eliminating the older/mechanical bumper edges – and replacing them with the current infrared safety edges or the new “light curtains” – improves passenger safety and reduces operating noise. Replacing old fluorescent and incandescent lighting fixtures with modern LED lighting helps save energy and enables stylish, contemporary looks for cab interiors. And upgrades to machines, governors, power units and traction equipment can all help vastly improve elevator operating efficiencies, ride quality, and avoid costly downtime.

All this can be very confusing. But, what is certain, because of the ravages of age and protracted operation, and the obsolescence of a growing number of parts, elevators and their performance do suffer from deterioration. As tenants in residential environments are trending older – and occupants of commercial properties have high expectations in an environment extremely competitive for tenants – keeping one’s elevators “up to snuff” is becoming increasingly essential.

 upgrade obsolete elevator parts

Many elevator components currently in service are now obsolete, for a number of possible reasons: they are no longer being manufactured, the manufacturer is out of business, and/or they no longer comply with current code. In all cases best practice is to upgrade such components, with some examples shown here, including out of date controllers, a rear brake and motor.
