  1. Stakeholders Meeting June 22, 2011 Division of Building Safety Industrial Safety Elevator Program

  2. A17.7 Performance-based safety code for elevators and escalators

  3. Two Types of Code • Prescriptive • A17.1 • Performance • A17.7

  4. AECO • Accredited Elevator/Escalator Certification Organization • Underwriter Laboratories • Liftinstituut • TUV SUD America

  5. GESR • Global Essential Safety Requirements • Globally agreed-upon essential safety requirements.

  6. LCU • Load-carrying unit (LCU) (car) • Part of an elevator designed to carry persons and/or other goods for the purpose of transportation.

  7. SP • Safety Parameter • A quantitative unit, the value of which provides a level of safety consistent with that provided by relevant codes and standards in current use in the elevator industry and good engineering practice.

  8. SR • Safety Requirement • Requirement intended to eliminate or sufficiently mitigate the risk of harm to users, non-users, and elevator personnel using or associated with elevators and escalators.

  9. A17.6-2010 Standard for Elevator Suspension, Compensation, and Governor Systems

  10. Three Parts • Part 1 • Stranded Carbon Steel Wire Ropes • Part 2 • Aramid Fiber Ropes • Part 3 • Noncircular Elastomeric Coated Steel Suspension Members

  11. Part 1 Stranded Carbon Steel Wire Ropes • Allows for rope diameters down to 4 mm • Specific replacement criteria for ropes

  12. Part 2 Aramid Fiber Ropes • Specific replacement criteria for ropes

  13. Part 3 Noncircular Elastomeric Coated Steel Suspension Members for Elevator • Specific replacement criteria for suspension members

  14. A17.1 - 2010 Safety Code for Elevators and Escalators

  15. Definitions Creep: slight incremental, natural movement of the suspension means over the arc of contact with the driving sheave due to tractive forces….Creep is independent of the motion status or direction of rotation of the driving sheave Note: Creep exists in all traction systems and is not loss of traction, and can occur while the drive sheave is stationary or rotating.

  16. Means, Compensation The method by which unbalanced forces due to suspension means are reduced, utilizing one or more compensation members and their terminations.

  17. Means, Suspension Tensile component that support, raise, and lower a car, counterweight, or both.

  18. Member, Compensation A single component of a traction elevator the weight of which provides tensile forces on the car and counterweight that reduce unbalanced forces due to the weight of the suspension means.

  19. Means, Suspension An individual load-carrying component of the suspension means (e.g., a single rope or belt)

  20. Suspension member, noncircular elastomeric-coated steel (hoisting) A noncircular suspension member, such as an elastomeric-coated steel belt constructed of encapsulated steel cords, used to raise and lower an elevator, dumbwaiter, or material lift car or its counterweight or both.
