Which of the following components is NOT typically found in the hoistway?

Circuit boards are generally not found in the hoistway. They are more commonly located in the machine room or control panel area, as they primarily function in processing signals and managing the elevator's operational features. The hoistway is primarily designed for the vertical movement of the elevator and housing components essential for that purpose.

Governors, deflector sheaves, and chain and sprocket systems, in contrast, are integral to the hoisting mechanism. Governors help in speed regulation and safety, ensuring that the elevator does not exceed its designated speed. Deflector sheaves guide the hoisting cables, allowing for smooth movement as the elevator ascends and descends. Chain and sprocket systems are part of the lifting mechanism that transfers motion from the motor to the elevator cab. This differentiation in function and location helps clarify why circuit boards are not typically associated with the hoistway's design and operation.
