1. What is the primary function of an elevator governor?
A. Control car speed during normal operation
B. Engage the door interlock system
C. Prevent overspeed of the elevator car
D. Manage elevator call buttons
The governor is a safety device that trips the safety mechanism if
the elevator exceeds its rated speed.
2. Which type of elevator motor is commonly used for high-rise
buildings?
A. Hydraulic
B. Traction
C. Pneumatic
D. Rack and pinion
Traction motors are more efficient for high-rise elevators because
they use ropes and sheaves instead of fluid power.
3. What does the buffer in an elevator shaft do?
A. Support the counterweight
B. Absorb impact if the car reaches the bottom of the shaft
C. Engage the door mechanism
D. Measure elevator speed
Buffers act as shock absorbers at the bottom of the hoistway to
prevent injury or equipment damage.
,4. The rated load of an elevator refers to:
A. Maximum weight the elevator can lift indefinitely
B. Maximum capacity during emergency operation
C. Maximum safe carrying capacity under normal conditions
D. Weight of the counterweight
Rated load defines the maximum weight the elevator is designed
to safely carry.
5. What is the main purpose of a traction sheave?
A. Guide the elevator rails
B. Transmit motion from the motor to the hoist ropes
C. Support the counterweight
D. Control the elevator door
The traction sheave grips the hoist ropes and moves the elevator
car.
6. Which safety device prevents the elevator from moving with open
doors?
A. Governor
B. Buffer
C. Door interlock
D. Safety brake
Door interlocks ensure the car cannot move unless doors are fully
closed and secured.
7. What is the function of an elevator brake?
A. Move the elevator car smoothly
B. Signal floor arrival
C. Hold the car stationary when stopped
D. Operate the doors
, The brake keeps the car at rest when it is not moving or during
power failure.
8. Which type of elevator uses a piston and fluid to move the car?
A. Traction
B. Hydraulic
C. Rack and pinion
D. Pneumatic
Hydraulic elevators rely on fluid pressure to raise and lower the
car, typically in low- to mid-rise buildings.
9. What is the purpose of the counterweight in a traction elevator?
A. Increase speed
B. Balance the weight of the car and reduce motor load
C. Operate doors
D. Prevent overspeed
Counterweights improve efficiency by reducing the amount of
work the motor must do.
10. The elevator controller is responsible for:
A. Mechanical leveling of the car
B. Coordinating car movement and stopping at floors
C. Maintaining the hoist ropes
D. Activating emergency alarms
The controller interprets user calls and safely manages elevator
movement.
11. In NYC, what is the minimum clearance required between an
elevator car and the hoistway wall?
A. 2 inches
B. 3 inches
