Q1.Under ASME A17.1, what is the maximum car speed at which the governor must trip and set the safeties?
A.Exactly the rated speed of the elevatorB.125% of the rated speed for most traction elevatorsC.150% of the rated speedD.The overspeed governor trips at any speed above rated speedB. 125% of the rated speed for most traction elevatorsExplanation: ASME A17.1 requires the overspeed governor to trip (activate safeties) at no more than 125% of the rated speed for most electric traction elevators with Type B safeties. The exact trip speed varies by safety type and elevator class. The governor mechanically trips a rope that activates the car safety, bringing the car to a controlled stop.

Q2.What is the purpose of a pit stop switch (pit emergency stop)?
A.To stop the car at the lowest landingB.To allow pit workers to disable the elevator from the pit for safe maintenance accessC.To automatically stop the car if the pit floodsD.To cut power to the car lighting in an emergencyB. To allow pit workers to disable the elevator from the pit for safe maintenance accessExplanation: ASME A17.1 requires a stop switch in the elevator pit accessible to workers entering the pit. Opening this switch breaks the safety circuit, preventing the elevator from moving while workers are in the pit. It is a critical lockout/tagout device. The pit stop switch, combined with proper LOTO procedures, protects mechanics from being struck by a moving car.

Q3.ASME A17.1 requires elevator hoistway doors to be self-closing and self-locking. This means:
A.Doors close automatically when not held open and cannot be opened from the landing unless the car is present and stoppedB.Doors lock from the inside so passengers cannot exit between floorsC.Doors close only when a passenger presses the 'door close' buttonD.Doors can be opened from the landing only with a special keyA. Doors close automatically when not held open and cannot be opened from the landing unless the car is present and stoppedExplanation: Hoistway (landing) doors are designed to close under gravity or a spring, and their interlock prevents them from being opened from the landing side unless the car is present within the landing zone (typically ±3 inches from floor level). This prevents passengers from falling into the hoistway. The hoistway door interlock is a critical safety device.

Q4.Under ASME A17.1, the minimum oil level in a hydraulic elevator's pump unit must be checked as part of:
A.Monthly maintenance onlyB.Annual testing onlyC.Every periodic maintenance inspection intervalD.Only when the elevator is first installedC. Every periodic maintenance inspection intervalExplanation: ASME A17.1 specifies maintenance intervals and tasks. Hydraulic fluid (oil) level must be checked and maintained at every periodic maintenance inspection. Low oil can cause slow operation, inability to reach top floor, or uncontrolled descent in some hydraulic systems. The oil level, condition, and any leaks must be documented in the maintenance log.
