Which term denotes the component with grooves for ropes on the moving system?

Explanation:
This question focuses on the part of the drive that actually handles the rope. The component with grooves for the rope is the traction sheave—the grooved wheel that the traction rope wraps around to transfer motion to the moving system. The grooves keep the rope aligned and provide the contact needed for friction to drive the steps or belt. Other options don’t fit because platform leveling relates to adjusting the platform’s height, pitch diameter is a measurement used to describe gear or pulley size rather than naming the grooved drive part, and emergency personnel access is a safety feature, not a drive component.
