ASME A17.1

ASME A17.1, 2019 Edition – Safety Code for Elevators and Escalators

ASME A17.1 is a safety code for elevators and escalators that is developed and published by the American Society of Mechanical Engineers (ASME). The code sets the minimum requirements for the design, construction, installation, operation, testing, inspection, maintenance, alteration, and repair of elevators, escalators, moving walks, dumbwaiters, material lifts, and other types of vertical transportation systems.

ASME A17.1 covers a wide range of topics related to elevator and escalator safety, including requirements for machine rooms, hoistway and pit access, car and counterweight safeties, emergency lighting and communications, door and gate systems, electrical and mechanical equipment, and more.

The code is updated regularly to incorporate new technologies and advances in the industry, and compliance with the code is mandatory in many jurisdictions in the United States.
