1. What is the primary purpose of an elevator governor?
A. Control cab lighting
B. Detect excessive car speed and initiate safety action
C. Open the hoistway door
D. Control the door operator
Correct Answer: B. Detect excessive car speed and initiate safety
action
Rationale: The governor monitors elevator car speed and
activates the safety system when overspeed occurs.
2. Which component supports the elevator car through
suspension ropes in a traction elevator?
A. Governor
B. Sheave
C. Counterweight
D. Buffer
Correct Answer: C. Counterweight
Rationale: The counterweight balances a substantial portion of
the car and load, reducing the power required to move the
elevator.
,3. What is the primary function of an elevator buffer?
A. Increase elevator speed
B. Absorb energy if the car or counterweight travels beyond its
normal limit
C. Operate the doors
D. Control the governor
Correct Answer: B. Absorb energy if the car or counterweight
travels beyond its normal limit
Rationale: Buffers provide controlled energy absorption at the
bottom of the hoistway.
4. Which standard is primarily associated with the safety code
for elevators and escalators?
A. ASME A17.1
B. ASME B30.5
C. NFPA 13
D. ASTM E84
Correct Answer: A. ASME A17.1
Rationale: ASME A17.1 is the Safety Code for Elevators and
Escalators and is referenced by Colorado conveyance
regulations.
5. What is the purpose of elevator guide rails?
A. Supply electrical power
B. Guide the car and counterweight vertically
C. Operate the door locks
D. Lubricate the ropes
,Correct Answer: B. Guide the car and counterweight vertically
Rationale: Guide rails maintain the proper travel path for the
elevator car and counterweight.
6. Which component changes the direction of the suspension
ropes in many traction elevators?
A. Traction sheave
B. Buffer
C. Governor switch
D. Door restrictor
Correct Answer: A. Traction sheave
Rationale: The traction sheave engages the suspension ropes
and can redirect them depending on the elevator configuration.
7. What is the purpose of a traction sheave?
A. Provide traction between the ropes and machine
B. Absorb hydraulic pressure
C. Operate the emergency alarm
D. Support the hoistway doors
Correct Answer: A. Provide traction between the ropes and
machine
Rationale: The traction sheave transfers motor torque to the
suspension ropes.
8. What is the primary purpose of an elevator counterweight?
A. Increase the car's weight
B. Balance the car and a portion of its rated load
, C. Stop the car during overspeed
D. Operate the door interlock
Correct Answer: B. Balance the car and a portion of its rated
load
Rationale: Counterbalancing reduces the motor power needed
to move the car.
9. What is the hoistway?
A. Elevator machine room only
B. Enclosed space in which the elevator car and counterweight
travel
C. Passenger waiting area
D. Electrical service room
Correct Answer: B. Enclosed space in which the elevator car and
counterweight travel
Rationale: The hoistway contains the vertical travel path and
associated elevator equipment.
10. What is the primary purpose of an elevator door interlock?
A. Increase car speed
B. Prevent operation unless the hoistway door is properly
secured
C. Increase motor voltage
D. Lubricate the door rollers
Correct Answer: B. Prevent operation unless the hoistway door
is properly secured
