Where is the machine room typically located for a traction elevator?

• A. Above the Elevator
• B. Below the Elevator
• C. Adjacent to the Shaft
• D. On the Roof

Answer: (A)

Traction elevator drives are normally housed in a machine room that sits above the hoistway. This top-location arrangement places the motor and control gear directly over the top pulley (sheave), keeping the rope path short and vertical and making the drive easier to align with the sheave. It also provides a dedicated, ventilated space for heat and noise, and gives convenient access for service without opening occupied floors. While newer machine-room-less designs exist, the traditional and most common setup for a traction system is a room above the elevator.
