1. What is the primary purpose of a safety brake in an elevator system?
A. Increase travel speed
B. Stop and hold the elevator car in an emergency
C. Reduce power consumption
D. Balance the counterweight
Correct Answer: B
Rationale: The safety brake is designed to stop and securely hold the
elevator car if overspeed or failure conditions occur.
2. Which component primarily supports and guides the elevator car?
A. Hoist ropes
B. Guide rails
C. Counterweight
D. Governor
,Correct Answer: B
Rationale: Guide rails keep the elevator car aligned and ensure smooth
vertical movement.
3. What is the function of a counterweight in a traction elevator?
A. Increase motor speed
B. Balance the car weight and reduce motor load
C. Act as emergency braking system
D. Control door operation
Correct Answer: B
Rationale: The counterweight offsets the car weight to reduce energy
required from the motor.
4. Which device detects overspeed conditions in an elevator?
A. Relay switch
B. Governor
C. Limit switch
D. Encoder
Correct Answer: B
Rationale: The governor monitors and triggers safety mechanisms if the
elevator exceeds safe speed.
5. What is the main purpose of interlocks on elevator doors?
A. Increase door speed
, B. Prevent movement unless doors are fully closed
C. Reduce electrical load
D. Control lighting
Correct Answer: B
Rationale: Interlocks ensure the elevator cannot operate when doors are
open.
6. What type of current is most commonly used in modern elevator
motor systems?
A. DC only
B. AC variable frequency drive
C. Solar current
D. Static current
Correct Answer: B
Rationale: VFD-controlled AC systems allow smooth acceleration and
energy efficiency.
7. What is the function of a buffer in an elevator system?
A. Control speed
B. Absorb impact at terminal limits
C. Increase torque
D. Balance voltage
, Correct Answer: B
Rationale: Buffers reduce impact if the car travels beyond its normal limits.
8. Which system controls elevator speed and direction?
A. Controller
B. Governor
C. Guide rail
D. Door operator
Correct Answer: A
Rationale: The controller manages all operational commands including
speed and direction.
9. What is the purpose of a machine room ventilation system?
A. Improve lighting
B. Prevent overheating of equipment
C. Increase elevator speed
D. Reduce noise in shaft
Correct Answer: B
Rationale: Ventilation prevents overheating of motors and control
equipment.
10. Which component carries electrical signals between car and
controller?
A. Guide shoes
