1. What is the primary purpose of a governor in an elevator system?
a) Control door operation
b) Monitor electrical supply
c) Prevent overspeed
d) Provide lighting in the shaft
The governor ensures the elevator does not exceed safe operating
speeds, activating the safety mechanism if necessary.
2. Which type of elevator uses ropes and counterweights?
a) Hydraulic
b) Pneumatic
c) Traction
d) Rack and pinion
Traction elevators rely on ropes and counterweights to move the
car efficiently.
3. What is the standard clearance between an elevator car and the
shaft wall?
a) 5 mm
b) 10 mm
c) 25 mm
d) 50 mm
, The clearance prevents friction and allows smooth operation while
maintaining safety.
4. In a hydraulic elevator, the cylinder is located:
a) Above the car
b) Below the car
c) Adjacent to the control panel
d) Inside the counterweight
Hydraulic elevators have the cylinder under the car to push it
upwards.
5. Which component converts electrical energy into mechanical
motion in elevators?
a) Governor
b) Motor
c) Brake
d) Controller
The motor drives the traction sheave or hydraulic pump, moving
the elevator.
6. What safety device stops the elevator in case of cable failure?
a) Door interlock
b) Limit switch
c) Safety brake
d) Buffer
The safety brake engages the rails if the elevator descends too
quickly or cables fail.
7. How often should an elevator undergo a full load test according to
typical regulations?
a) Monthly
, b) Annually
c) Every 5 years
d) Biannually
Annual testing ensures the elevator can safely carry its rated load.
8. Which type of brake is commonly used in traction elevators?
a) Disc brake
b) Drum brake
c) Electromagnetic brake
d) Hydraulic brake
Electromagnetic brakes hold the elevator in position when the
motor is not running.
9. What does the term “pit depth” refer to?
a) Distance between car and counterweight
b) Distance from top floor to roof
c) Distance from bottom floor to shaft floor
d) Depth of machine room
Pit depth is crucial for safety and clearance of elevator
components at the bottom of the shaft.
10. What is the function of a door interlock?
a) Close doors manually
b) Prevent elevator movement when doors are open
c) Control lighting
d) Engage the motor
Door interlocks ensure the car cannot move with doors open,
preventing accidents.
11. Which fluid is commonly used in hydraulic elevators?
a) Water
