1. A traction elevator uses which primary method to move the car?
A. Hydraulic fluid pressure
B. Pneumatic air compression
C. Ropes and counterweight driven by traction machine
D. Magnetic levitation only
Answer: C
Traction elevators operate using steel hoist ropes that pass over a
traction sheave driven by an electric motor, with a counterweight
balancing the car to reduce energy demand.
2. What is the primary purpose of an elevator counterweight?
A. Increase car speed
B. Balance the weight of the car and partial load
C. Stop the elevator at landings
D. Control door operation
, Answer: B
The counterweight offsets the weight of the car plus a portion of the
rated load, reducing motor effort and improving efficiency.
3. Which device prevents an elevator car from falling in case of rope
failure?
A. Governor and safety mechanism
B. Limit switch
C. Door interlock
D. Buffer spring
Answer: A
The overspeed governor activates the safety mechanism, which
clamps the rails and stops the car during excessive descent speed or
rope failure conditions.
4. What is the function of an elevator governor?
A. Control door timing
B. Measure car load
C. Detect overspeed and trigger safety device
D. Balance counterweight
Answer: C
The governor monitors car speed and initiates the safety system if
overspeed conditions occur.
5. Which component guides the elevator car along its travel path?
A. Hoist ropes
, B. Guide rails
C. Sheave
D. Governor rope
Answer: B
Guide rails ensure smooth vertical travel and maintain alignment of
the car and counterweight.
6. What is the purpose of a buffer in an elevator system?
A. Increase speed efficiency
B. Stop the car gently at terminal limits
C. Control electrical current
D. Balance rope tension
Answer: B
Buffers absorb energy and reduce impact if a car or counterweight
travels beyond its normal limit.
7. Which hydraulic component directly raises and lowers a hydraulic
elevator car?
A. Traction motor
B. Pump and cylinder piston
C. Governor assembly
D. Counterweight rope
Answer: B
Hydraulic elevators use a pump to move oil into a cylinder, extending
a piston that lifts the car.
, 8. What is the primary safety function of a door interlock?
A. Increase speed
B. Prevent movement when doors are open
C. Balance load
D. Control lighting
Answer: B
Door interlocks ensure the elevator cannot operate unless all doors
are securely closed and locked.
9. Which electrical component controls the sequencing of elevator
operations?
A. Transformer
B. Controller
C. Resistor
D. Capacitor
Answer: B
The controller coordinates all elevator functions including motion,
leveling, and door operation.
10. What is the purpose of a leveling system in elevators?
A. Increase motor torque
B. Align car floor with landing floor
C. Reduce vibration only
D. Control emergency braking
Answer: B
