Elevator Mechanic Practice Exam

What is needed to coordinate the movement and to dispatch hall calls?

1. A central processing unit

2. A floor indicator

3. A group controller

4. An elevator motor

The correct answer is: A group controller

The correct answer is the group controller, which plays a critical role in coordinating elevator movement and managing hall calls efficiently within a system of multiple elevators. This device operates by processing requests initiated from different floors and dispatching the appropriate elevator to respond to those calls. It optimizes the elevator traffic, allows for grouped dispatching of elevators, and ensures that the system operates smoothly in high-demand scenarios. A central processing unit, while important for various electronic functions, does not specifically focus on the coordination of elevator dispatching. A floor indicator simply displays the current floor or movement status of the elevator; it does not manage or coordinate calls. An elevator motor is responsible for the physical movement of the elevator car itself but does not have a role in the strategic management of call responses or coordination among multiple elevators.
