1.
Which code primarily governs elevator installation and safety standards in the
United States?
A. NEC Article 430
B. OSHA 29 CFR 1926
C. ASME A17.1 Safety Code for Elevators and Escalators
D. NFPA 70E
Answer: C
Rationale: ASME A17.1 is the primary safety code governing the design,
installation, operation, inspection, testing, maintenance, and alteration of
elevators and escalators in the United States. NEC and OSHA standards may
apply to specific electrical or workplace safety aspects, but A17.1 is the main
governing standard for elevator systems as a whole.
2.
What is the primary function of an elevator governor?
,A. Increase motor torque
B. Control car leveling accuracy
C. Activate safety mechanisms during overspeed conditions
D. Regulate door opening speed
Answer: A
Rationale: The elevator governor monitors car speed and triggers safety devices
when overspeed conditions occur. It mechanically activates safety gear to stop
the car and prevent free fall, making it a critical safety component in traction
elevator systems.
3.
Which component directly supports and lifts the elevator car in a traction system?
A. Hydraulic piston
B. Counterweight guide rail
C. Hoist ropes (steel wire ropes)
D. Buffer springs
Answer: C
Rationale: In traction elevators, steel hoist ropes connect the car and
counterweight and pass over a traction sheave driven by the motor. Friction
between ropes and sheave enables vertical movement of the car.
4.
Which device prevents the elevator car from falling in a free-fall condition?
A. Drive motor
B. Limit switch
C. Safety gear assembly
D. Selector tape
,Answer: D
Rationale: The selector tape is used for position control and floor selection, not
safety stopping. Safety gear assemblies engage guide rails during overspeed or
free-fall conditions, preventing uncontrolled descent of the elevator car.
5.
What is the purpose of a hydraulic elevator pump unit?
A. To balance counterweights
B. To regulate door timing
C. To force hydraulic fluid into the cylinder to raise the car
D. To monitor speed regulation
Answer: B
Rationale: Hydraulic elevators operate by pumping oil into a cylinder, which
pushes a piston upward to raise the car. The pump unit is the source of pressure
that enables vertical movement in hydraulic systems.
6.
Which electrical system is most commonly used for modern elevator motor
control?
A. Relay logic only
B. Pneumatic control system
C. Variable Frequency Drive (VFD)
D. Mechanical cam switches
Answer: C
Rationale: VFD systems control motor speed and torque by varying frequency
and voltage, enabling smooth acceleration, deceleration, and energy efficiency.
They are widely used in modern elevator installations.
, 7.
What is the primary purpose of an elevator counterweight?
A. Increase car speed
B. Reduce door wear
C. Balance the weight of the car and partial load
D. Prevent electrical faults
Answer: D
Rationale: Counterweights balance the elevator car and a portion of its rated
load, reducing motor effort and improving energy efficiency. This also reduces
wear on hoisting equipment.
8.
Which device is used to detect car position in the hoistway?
A. Brake coil
B. Governor switch
C. Encoder or selector system
D. Oil buffer
Answer: A
Rationale: Brake coils control motor braking but do not detect position. Encoders
and selector systems track car position within the hoistway and provide input to
the controller for floor leveling and stopping accuracy.
