A crank for manual operation is provided in which part of the elevator system?

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

Answer: (A)

Having a hand crank for manual operation is tied to the drive system, so it is placed in the machine room where the elevator’s motor, drive equipment, and controls reside. This location keeps manual operation safely contained and accessible to trained personnel during power outages or drive failures, allowing the car to be moved by engaging the drive and rotating the crank. The hoistway and car cab are vertical shaft and passenger spaces, which would be unsafe and impractical for manual control. The pit is below the car and is used for inspection and clearance, not for operating the system.
