1. What is the primary purpose of an elevator governor?
A. To power the hoist motor
B. To lubricate guide rails
C. To detect excessive car speed
D. To monitor door operation
Answer: C
Rationale: The governor detects overspeed and triggers the safety to stop
the elevator.
2. Which rope construction is most commonly used for elevator hoist
ropes?
A. Fiber core
B. 6×19
C. 8×19 Seale
D. 2×7
Rationale: 8×19 Seale offers superior flexibility and strength for traction
elevators.
,3. The minimum overhead clearance for a traction elevator is required to
ensure:
A. More car occupancy
B. Better traction efficiency
C. Safe buffer and equipment space
D. Increased counterweight travel
Rationale: Overhead clearance ensures safe stopping, equipment
placement, and buffer space.
4. What device stops an elevator from operating when the doors are not
fully closed?
A. Governor
B. Door interlock
C. Limit switch
D. Selector
Rationale: Door interlocks prevent motion unless doors are secured.
5. What is the primary function of a buffer in an elevator shaft?
A. Slow normal operation
B. Absorb impact energy during an emergency stop
C. Prevent overspeed
D. Assist the counterweight
Rationale: Buffers protect the elevator car and counterweight if they travel
too far.
6. Which type of elevator uses a sheave and counterweight system?
A. Hydraulic
B. Roped hydraulic
C. Rack-and-pinion
, D. Traction
Rationale: Traction elevators use ropes, sheaves, and counterweights.
7. In elevator electrical systems, what does a “limit switch” prevent?
A. Overspeed
B. Overtravel beyond designed limits
C. Power supply fluctuations
D. Excessive door force
Rationale: Limit switches stop the car if it passes normal stopping points.
8. The counterweight in a traction elevator typically equals:
A. 10% of rated load
B. Car weight + 40–50% of rated load
C. Passenger weight only
D. Car weight only
Rationale: Counterweights offset a portion of the load to reduce motor
effort.
9. Which component provides acceleration and deceleration control in
modern elevator drives?
A. Star-delta starter
B. Variable frequency drive (VFD)
C. Fuse block
D. Door controller
Rationale: VFDs allow smooth and efficient motor speed control.
10. What type of hydraulic oil is commonly used in hydraulic elevators?
