The manual crank for moving the elevator car is located in which part of the system?

• A. Pit
• B. Machine room
• C. Hoistway
• D. Car cab

Answer: (B)

The key idea is where the manual control for moving the elevator car is located. The manual crank is part of the hoisting machinery and is placed in the machine room, where the drive motor, gears, and related equipment reside. This location provides a safe, direct interface to the drive system for manual operation during maintenance or a power outage. The pit houses safety components and access to equipment below, the hoistway is the shaft itself, and the car cab is the moving interior of the car—none of these are where the manual crank is mounted. So, the manual crank being in the machine room makes the most sense for controlled, safe manual operation of the elevator.
