1.An elevator inspector reviewing a traction elevator system in a high-rise
building in New York City is primarily concerned with verifying compliance
with which of the following safety standards governing installation,
operation, and maintenance requirements?
A. ASME A17.1 Safety Code for Elevators and Escalators
B. National Electrical Code Article 250 only
C. OSHA General Industry Standard 1910.147 exclusively
D. International Fire Code Chapter 3 only
Answer: A
Rationale: The ASME A17.1 Safety Code is the primary governing standard
for elevator safety, covering design, installation, operation, inspection, and
maintenance requirements, making it the most comprehensive and
relevant code for elevator inspection.
2. During a routine inspection, an inspector discovers that an elevator’s
emergency stop switch does not interrupt the control circuit as
intended. What is the most appropriate classification of this defect?
A. Minor cosmetic defect requiring no action
B. Critical safety violation requiring immediate shutdown
,C. Permitted variance under maintenance discretion
D. Operational preference issue
Answer: B
Rationale: An emergency stop failure is a critical safety defect because it
directly compromises passenger safety and requires immediate removal of
the elevator from service until corrected.
3. Which component in a traction elevator system is primarily responsible
for maintaining counterbalance between the car and the
counterweight?
A. Governor
B. Hoist ropes
C. Buffer springs
D. Door interlock system
Answer: B
Rationale: Hoist ropes connect the car and counterweight and are essential
for maintaining balance and enabling controlled vertical movement in
traction elevator systems.
4. What is the primary purpose of an elevator governor?
A. To regulate door opening speed
B. To activate safety mechanisms if overspeed occurs
C. To balance hydraulic pressure
D. To control lighting in the cab
Answer: B
Rationale: The governor detects excessive speed and triggers safety
mechanisms to stop the elevator, preventing free fall or uncontrolled
descent.
, 5. An inspector finds oil leakage in the machine room of a hydraulic
elevator. What is the most immediate concern?
A. Aesthetic maintenance issue
B. Increased energy consumption only
C. Environmental hazard and potential system failure
D. Reduced cabin lighting efficiency
Answer: C
Rationale: Hydraulic oil leaks pose environmental risks and can indicate
system failure, including pressure loss that may affect safe elevator
operation.
6. Which device ensures that an elevator door cannot open unless the
car is properly aligned at a landing?
A. Door operator motor
B. Door interlock
C. Selector switch
D. Buffer assembly
Answer: B
Rationale: Door interlocks prevent doors from opening unless the elevator
car is correctly positioned at a landing, ensuring passenger safety.
7. What is the function of a buffer in an elevator system?
A. To regulate electrical voltage
B. To absorb impact energy at terminal landings
C. To control door closing speed
D. To lubricate guide rails
Answer: B
Rationale: Buffers are safety devices designed to absorb and reduce impact
energy if the elevator car overtravels beyond its normal limits.
, 8. In a hydraulic elevator system, what component generates the lifting
force?
A. Counterweight
B. Hydraulic piston
C. Governor
D. Traction sheave
Answer: B
Rationale: The hydraulic piston uses pressurized fluid to raise and lower the
elevator car in hydraulic systems.
9. What is the primary purpose of a machine room ventilation system in
elevator installations?
A. Improve passenger comfort inside the car
B. Prevent overheating of mechanical and electrical equipment
C. Reduce elevator speed during peak hours
D. Increase traction efficiency of ropes
Answer: B
Rationale: Proper ventilation prevents overheating of machinery and
electrical systems, ensuring reliable and safe elevator operation.
10. What is the required function of an elevator hoistway enclosure?
A. Provide decorative aesthetics
B. Separate elevator equipment from public access and prevent hazards
C. Increase building lighting
D. Store maintenance tools
Answer: B
Rationale: Hoistway enclosures isolate elevator shafts to prevent
unauthorized access and reduce risk of injury or entrapment.
