1. What is the primary purpose of a governor in an elevator system?
A) Control the door operation
B) Limit the maximum speed of the elevator
C) Monitor the weight load
D) Operate the emergency alarm
Answer: B) Limit the maximum speed of the elevator
Rationale: The governor acts as a safety device to prevent the elevator from
exceeding its rated speed, activating the safety brakes if necessary.
2. Which of the following is considered a “hoistway” component?
A) Control panel
B) Elevator cab
C) Elevator pit
D) Traction sheave
Answer: D) Traction sheave
Rationale: The hoistway includes components that guide and move the elevator,
such as rails, ropes, and the traction sheave.
,3. What is the standard frequency of periodic elevator inspection in BC for
passenger elevators?
A) Monthly
B) Every 6 months
C) Annually
D) Every 5 years
Answer: B) Every 6 months
Rationale: BC’s Safety Standards Act requires elevators to be inspected semi-
annually to ensure operational and safety compliance.
4. The term “counterweight” in an elevator system refers to:
A) A weight used to balance the elevator cab
B) A weight that slows the cab in emergencies
C) A device to prevent door malfunction
D) A device used in hydraulic elevators only
Answer: A) A weight used to balance the elevator cab
Rationale: The counterweight reduces the energy required to move the cab and
helps maintain smooth operation.
5. Which of the following is a common cause of elevator overspeed?
A) Misaligned door operator
B) Malfunctioning governor
C) Worn elevator cab flooring
D) Loose control panel buttons
Answer: B) Malfunctioning governor
Rationale: The governor monitors elevator speed and triggers safety brakes if
speed limits are exceeded; a malfunction can lead to overspeed.
,6. What is the purpose of the buffer in the elevator pit?
A) Reduce cabin vibration
B) Slow and absorb impact if the elevator reaches the bottom of the hoistway
C) Keep the counterweight aligned
D) Protect the control panel
Answer: B) Slow and absorb impact if the elevator reaches the bottom of the
hoistway
Rationale: Buffers act as a safety mechanism, absorbing impact energy in case of
an over-travel scenario.
7. In a traction elevator, the ropes attach to:
A) The governor
B) The counterweight and the elevator cab
C) The pit buffer
D) The door operator
Answer: B) The counterweight and the elevator cab
Rationale: Traction ropes connect the cab and counterweight to transmit motion
and balance the system.
8. What type of braking system is typically used in elevators?
A) Disc brakes only
B) Friction brakes
C) Spring-applied, electrically released brakes
D) Drum brakes
Answer: C) Spring-applied, electrically released brakes
Rationale: This design ensures that brakes automatically engage in the event of
power failure, providing safety.
, 9. Which device is used to prevent the elevator from moving when doors are
open?
A) Door interlock
B) Safety governor
C) Brake caliper
D) Pit buffer
Answer: A) Door interlock
Rationale: Door interlocks ensure the elevator cannot move while doors are open,
preventing accidents.
10. What is the primary purpose of the hydraulic elevator pump?
A) Lift the counterweight
B) Supply oil under pressure to move the piston and lift the cab
C) Activate the governor
D) Control the door operation
Answer: B) Supply oil under pressure to move the piston and lift the cab
Rationale: In hydraulic elevators, the pump provides hydraulic fluid under pressure
to move the cab smoothly.
11. Which of the following is a requirement for elevator pit lighting?
A) Minimum of 100 lux at floor level
B) Only emergency lighting is required
C) Motion-sensing lights only
D) No lighting required if the elevator is operational
Answer: A) Minimum of 100 lux at floor level
Rationale: Adequate lighting in the pit ensures safe maintenance and inspection.
12. What is the function of the buffer stop on a traction elevator counterweight?
