NEIEP Escalators and Moving Walks (845) Practice Test

In a chair lift, the part that actually transmits the motion in the drive system is the steel cable. This rope-like element runs around the drive drums and pulleys, carrying the load and pulling the chairs along the line as the motor turns the drums. It’s the component specifically used to transfer power and movement, making it the term that defines the drive mechanism. The other options don’t describe the moving element: carpeting requirements relate to floor or interior finishes, manufacturer’s specifications cover overall requirements and tolerances, and intermediate brackets are structural supports, not the device that delivers motion.
