2026 Q&A | Instant Download Pdf
1. What is the primary function of an elevator governor?
A. Increase speed of the elevator
B. Control cabin lighting
C. Activate safety braking system during overspeed
D. Balance elevator counterweights
The governor detects overspeed conditions and triggers safety
mechanisms to stop the elevator.
2. Which component counterbalances the weight of the elevator
car?
A. Hoist motor
B. Brake drum
C. Counterweight
D. Control panel
The counterweight reduces motor load and improves efficiency.
3. What is the most common type of elevator drive system?
A. Hydraulic piston
B. Pneumatic lift
, C. Traction system
D. Magnetic levitation
Traction elevators use ropes and sheaves for smooth vertical
movement.
4. What is the purpose of guide rails in an elevator system?
A. Provide electrical grounding
B. Supply power to the car
C. Guide and stabilize the elevator car and counterweight
D. Reduce motor noise
Guide rails keep the car aligned during travel.
5. Which safety device prevents elevator free fall?
A. Relay switch
B. Door interlock
C. Safety brake (safety gear)
D. Limit switch
Safety gears clamp onto guide rails during failure conditions.
6. What type of motor is commonly used in modern elevators?
A. DC series motor only
B. Gas-powered engine
C. AC induction motor with VFD control
D. Steam turbine
Variable frequency drives allow smooth acceleration and
deceleration.
, 7. What is the function of a hoist rope?
A. Control door movement
B. Provide lighting power
C. Lift and lower the elevator car
D. Cool the motor
Hoist ropes support and move the elevator car.
8. What device detects car position in the shaft?
A. Transformer
B. Relay board
C. Encoder or position sensor system
D. Fuse block
Position sensors ensure accurate leveling and stopping.
9. What is the purpose of a buffer in an elevator system?
A. Increase speed
B. Reduce power usage
C. Absorb impact at the bottom of the shaft
D. Control door timing
Buffers prevent damage during overtravel.
10. Which system controls elevator door operation?
A. Hydraulic valve
B. Governor system
C. Door operator mechanism
