SUBJ: Single Speed AC (SSAC) Elevators
In an effort to better inform and protect our customers, we would like to update you of the potential leveling problem with the Single Speed AC Elevators.
Single speed AC passenger elevators are a slow speed, low-capacity passenger unit and were created early in the 1960’s. At the time, these elevators were competitively priced and where mostly used in residential buildings.
These elevators are now obsolete and are no longer being made or installed. The current New York State code requires that elevators, when arriving at a floor, the elevator must stop accurately and consistently within a finite limit of only one half inch above or below floor level. This is reflected in the following excerpt from the current edition of The American Harmonized Elevator code the CSA B44/ASME A17.1.
Elevators with the potential of not leveling probably will be a tripping hazard to everyone, particularly the elderly and those with disabilities.
Today’s elevator does not even use the brakes to stop the car, as was done in the past and with new technology, the control systems will consistently stop the elevator at floor level (+-1/4 inch).
To avoid any possible liability due to levelling and/or Single Speed AC problems, we a recommend modernization be performed on this type of elevator. Please contact us today for our recommendations and pricing.

Here at D & D Elevator, we are constantly striving to keep the public and the riding personnel included in the need for safety when travelling in elevators and on escalators. We would like to share some of these recommendations with you.

During the month of October, to discuss a special project in the White Plains area, I had the good fortune to visit Delaware Elevator. Delaware Elevator is a manufacturer that supports not only us, but many elevator contractors.
Delaware Elevator is a manufacturer of Residential and Commercial elevator equipment. They have an expert design team that can assist with those specialized design projects. When a specific project needs to be fast tracked and delivery times are of vital importance to the overall project, they go above and beyond to accommodate their customers.
To discuss our most recent project, where they will be providing engineering and Group 1 elevator equipment for 4 new MRL installations, I met with Mariano Escobal, the Chief Engineer and Walt Smakulski, the Plant Manager. As usual they were very accommodating and worked out a plan to deliver the equipment ahead of our already tight schedule.
During this time, they also treated me to a tour of the Plant where we met the CEO and owner Charles “Pete” Meeks. Pete then revealed their new residential package and explained plans for the new Delaware Elevator expansion in 2014.
We then toured the new Delaware Elevator training facilities. This is one of the most impressive training centers I have seen during my 30+ years in the elevator business. This center can accommodate over 75 Technicians at any given time and while I was there I witnessed the newest model MRL system that was being installed right in the middle of the training center. Since both Delaware and D & D Elevator’s participate in the NAEC “CET” Program, we then discussed training partnerships.
Overall a great trip and another learning experience for yours truly.
