Q1. What is the primary function of a safety governor in an elevator system?
A. To regulate the speed of the motor B. To control the door opening mechanism C. To
monitor hydraulic pressure levels D. To limit the travel distance of the cab E. To trigger
the safety device when overspeed occurs ✓
CORRECT ANSWER: E RATIONALE: The governor is a speed-sensing
device that activates the car's safety when the descending speed exceeds the rated
speed by a specified percentage, as required by ASME A17.1.
Q2. Which law states that the voltage across a resistor is proportional to the
current flowing through it?
A. Newton's Second Law B. Faraday's Law C. Ohm's Law ✓ D. Kirchhoff's Voltage Law
E. Coulomb's Law
CORRECT ANSWER: C RATIONALE: Ohm's Law states V = IR, meaning
voltage equals current multiplied by resistance. It is the foundational law for basic
electrical circuit analysis.
Q3. What does ASME A17.1 govern?
A. Escalator manufacturing standards B. Electrical safety for industrial equipment C.
Safety code for elevators and escalators ✓ D. Hydraulic pressure standards E.
National building construction codes
CORRECT ANSWER: C RATIONALE: ASME A17.1 is the Safety Code for
Elevators and Escalators, the primary code governing the installation, operation, and
maintenance of elevator equipment in North America.
Q4. In a series circuit, if one component fails open, what happens?
,A. Current increases through the remaining components B. Voltage increases across
remaining components C. Current stops flowing through the entire circuit ✓ D. Only
the failed component loses power E. The circuit operates normally at reduced capacity
CORRECT ANSWER: C RATIONALE: In a series circuit, all components
share the same current path. An open failure breaks the single path, stopping current
flow through the entire circuit.
Q5. What type of rope is most commonly used for elevator hoisting?
A. Fiber core rope B. Hemp center rope C. Independent wire rope core (IWRC) ✓ D.
Chain-link wire rope E. Braided nylon rope
CORRECT ANSWER: C RATIONALE: IWRC rope provides superior support
and resistance to crushing and deformation under heavy loads, making it the standard
for elevator hoisting applications.
Q6. What is the purpose of a pit buffer in an elevator system?
A. To absorb hydraulic fluid overflow B. To support the guide rail brackets C. To
cushion the car or counterweight at the end of travel ✓ D. To prevent water from
entering the pit E. To store the slack of the traveling cable
CORRECT ANSWER: C RATIONALE: Pit buffers (oil or spring type) are
designed to absorb and dissipate kinetic energy of the car or counterweight in the event
of overtravel, protecting occupants and structure.
Q7. What is the standard minimum headroom clearance required above the
elevator car per ASME A17.1?
A. 18 inches B. 24 inches C. 24 inches for the car top clearance ✓ D. 36 inches E. 48
inches
CORRECT ANSWER: C RATIONALE: ASME A17.1 requires a minimum top-
of-car clearance to protect mechanics working on top of the car. The specific
requirements vary by installation type but ensure safe working space.
Q8. In a hydraulic elevator, what is the function of the check valve?
,A. To regulate the pump speed B. To filter contaminants from the fluid C. To prevent the
car from lowering when the pump is off ✓ D. To control the pressure relief sequence
E. To prevent backflow into the reservoir
CORRECT ANSWER: C RATIONALE: The check valve allows fluid to flow in
one direction only — from pump to cylinder — preventing the elevator car from lowering
when the pump is not running.
Q9. Which motor type is most commonly used in variable voltage variable
frequency (VVVF) elevator drives?
A. DC shunt motor B. Universal motor C. AC induction motor ✓ D. Synchronous
reluctance motor E. Brushed DC motor
CORRECT ANSWER: C RATIONALE: AC induction motors are robust, low
maintenance, and well-suited for VVVF drive control, which varies both voltage and
frequency to achieve smooth speed control in modern elevators.
Q10. What does the term "rope lay" refer to?
A. The diameter of individual wire strands B. The number of strands in a rope C. The
distance along the rope for one complete strand helix ✓ D. The material
composition of the rope core E. The breaking strength of the rope
CORRECT ANSWER: C RATIONALE: Rope lay refers to the length along the
rope axis in which one strand completes a full helical turn. It affects flexibility, fatigue life,
and traction characteristics.
Q11. What is the purpose of the leveling device in an elevator?
A. To balance the counterweight load B. To stop the car at exactly the top terminal floor
C. To bring the car to an accurate floor level position ✓ D. To regulate the motor
torque during deceleration E. To prevent the doors from opening between floors
CORRECT ANSWER: C RATIONALE: The leveling device senses the car's
position relative to the floor landing and makes fine corrections to ensure the car sill
aligns with the hall floor, improving passenger safety and accessibility.
, Q12. What is the minimum number of wire rope suspensions required for a
traction elevator under ASME A17.1?
A. One B. Two C. Two for passenger elevators ✓ D. Four E. Three minimum for any
configuration
CORRECT ANSWER: C RATIONALE: ASME A17.1 requires a minimum of
two wire ropes for suspension of passenger elevators, ensuring redundancy in the
hoisting system.
Q13. What tool is used to measure the resistance of a conductor?
A. Voltmeter B. Ammeter C. Ohmmeter ✓ D. Wattmeter E. Oscilloscope
CORRECT ANSWER: C RATIONALE: An ohmmeter measures electrical
resistance in ohms. It must be used on a de-energized circuit to obtain accurate
readings and avoid damaging the meter.
Q14. What is the function of a traveling cable in an elevator?
A. To connect the pit buffer to the car frame B. To support the counterweight C. To
provide electrical connections between the car and the fixed wiring ✓ D. To carry
hydraulic fluid to the car E. To support the governor rope
CORRECT ANSWER: C RATIONALE: The traveling cable is a flexible multi-
conductor cable that travels with the car and provides continuous electrical connections
for lighting, controls, door operator, and communications.
Q15. What is the safety factor required for elevator wire ropes per ASME A17.1?
A. 5:1 B. 6:1 C. 7:1 for traction elevators with rated speed over 150 fpm ✓ D. 8:1 E.
10:1
CORRECT ANSWER: C RATIONALE: ASME A17.1 requires a minimum
design factor (safety factor) of at least 7.60 for wire ropes on traction elevators
operating at higher speeds, ensuring adequate margin against rope failure.
