Division of Building Safety
Performance-based safety code for elevators and escalators
Standard for Elevator Suspension, Compensation, and Governor Systems
Safety Code for Elevators and Escalators
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.
The method by which unbalanced forces due to suspension means are reduced, utilizing one or more compensation members and their terminations.
Tensile component that support, raise, and lower a car, counterweight, or both.
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.
An individual load-carrying component of the suspension means (e.g., a single rope or belt)
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.
Cars are required to have two lamps or sets of lamps
