  • November 2021 Meeting


    Historical Perspective – overview

         Elevator installations in North America are estimated to be 1,000,000; escalators add another 44,000.  That translates to something in excess of 120 billion passenger rides per year!

        2021 marks the centennial anniversary of ASME’s A17.1 Safety Code for Elevators and Escalators, first published in 1921.  In the century which followed, technology has changed; commitment to design and operational integrity has not.    Safety for installers, service personnel, and the riding public continues to be the primary focus of ASMEs A17 family of standards.

         Current ASME A17 membership (Standards Committee and working committees) includes approximately 300 volunteers who represent an array of interests – design, manufacture, installation, jurisdictional authorities, inspectors, consultants, etc.  Code development is based on a consensus approach.  Decisions don’t have to be unanimous, but any dissenting votes have the option of a formal appeal.  Balance of interest requirements in accordance with ANSI requirements assures a level playing field.

         As technology has advanced, historical developments in the elevator and escalator design present a colorful mosaic of progress, including some disappointments among many successes.  Developments in software monitoring, control technology, and AI promise a diversified and stimulating future.

         For our November 10, 2021 meeting, we are fortunate to have Past Codes and Standards Senior Vice President Jim Coaker tell us about the ASME Elevator Safety Code. Jim Coaker will chronologically step through highlights of a century of development, focus on selected milestones, and share behind-the-scenes insights.  There will be time for questions and open discussion.
