Question 1
What is the primary purpose of an elevator governor?
A. To regulate car door timing
B. To control motor voltage
C. To activate safety gear in overspeed conditions
D. To balance counterweight tension
Correct Answer: C
Rationale: The elevator governor is a critical safety device designed to detect
when the elevator car exceeds its rated speed in the downward direction. When
overspeed is detected, the governor mechanically triggers the safety gear
located on the elevator car, causing it to grip the guide rails and bring the car to
a controlled stop. This prevents free fall conditions and catastrophic failure. It
operates independently of the main control system, ensuring redundancy in
safety.
Question 2
Which code most directly governs elevator installation safety standards in the
United States?
,A. ASME A17.1
B. NEC Article 430
C. OSHA 1910.120
D. NFPA 70B
Correct Answer: A
Rationale: ASME A17.1, also known as the Safety Code for Elevators and
Escalators, is the primary regulatory standard governing the design, installation,
operation, inspection, and maintenance of elevators in the United States. While
NEC provides electrical standards, ASME A17.1 specifically addresses mechanical
and operational safety requirements unique to vertical transportation systems.
Question 3
What component primarily supports the elevator car and counterweight in a
traction system?
A. Hydraulic piston
B. Steel wire ropes
C. Guide rail brackets
D. Buffers
Correct Answer: B
Rationale: In traction elevator systems, steel wire ropes (or cables) are the
primary load-bearing elements that connect the elevator car and counterweight
over a traction sheave. The friction between the ropes and the sheave allows
controlled movement. These ropes are engineered for high tensile strength and
durability under dynamic loading conditions.
Question 4
What is the function of an elevator counterweight?
,A. To increase motor torque
B. To balance the car load and reduce motor effort
C. To control door closing speed
D. To regulate hydraulic pressure
Correct Answer: D
Rationale: The counterweight in a traction elevator system is designed to offset
the weight of the elevator car plus approximately 40–50% of its rated load. This
balancing reduces the energy required by the motor to move the car, improving
efficiency, reducing wear, and ensuring smoother operation.
Question 5
Which device prevents an elevator car from moving with doors open?
A. Governor switch
B. Door interlock
C. Limit switch
D. Buffer system
Correct Answer: B
Rationale: Door interlocks are safety devices that ensure the elevator car cannot
operate unless all doors are fully closed and locked. They are critical to
passenger safety, preventing movement when passengers could be entering or
exiting the car. These interlocks are part of a redundant safety circuit system.
Question 6
What type of elevator system uses fluid pressure for movement?
A. Traction system
B. Gearless system
C. Hydraulic system
D. Drum winding system
, Correct Answer: A
Rationale: Hydraulic elevators use pressurized hydraulic fluid to move a piston
that lifts the elevator car. This system is commonly used in low-rise buildings due
to its cost-effectiveness and simpler mechanical design compared to traction
systems. The movement is controlled via valves regulating fluid flow.
Question 7
What is the primary function of elevator guide rails?
A. To supply power to the car
B. To guide car and counterweight movement
C. To regulate door timing
D. To support hydraulic pressure
Correct Answer: C
Rationale: Guide rails provide a rigid path for both the elevator car and
counterweight, ensuring smooth vertical movement and preventing lateral
sway. They also serve as a reaction surface for safety gear activation during
overspeed or emergency braking events.
Question 8
Which electrical component stops the elevator at floor level?
A. Relay coil
B. Encoder
C. Leveling sensor
D. Transformer
Correct Answer: C
Rationale: Leveling sensors ensure that the elevator car aligns precisely with the
landing floor. These sensors provide feedback to the control system, which
