1. What is the primary purpose of an elevator governor?
a. To control the cab lighting
b. To regulate door speed
c. To initiate overspeed safety action
d. To increase motor torque
Rationale: The governor monitors elevator speed and, when an
overspeed condition occurs, activates the appropriate safety
mechanism. This helps prevent uncontrolled car movement and
provides an important layer of protection.
2. Which component supports the elevator car and transfers its load
to the suspension system?
a. Door operator
b. Governor
,c. Car frame (sling)
d. Limit switch
Rationale: The car frame, commonly called the sling, surrounds or
supports the elevator car and provides the structural connection
between the car and its suspension means.
3. What is the main function of elevator guide rails?
a. Supply electrical power to the car
b. Operate the hoist motor
c. Guide the car and counterweight along a controlled path
d. Control passenger access
Rationale: Guide rails provide a rigid vertical path for the elevator car
and counterweight. They also interact with safety devices when
required.
4. In a traction elevator, what component provides the driving force
for the suspension ropes?
a. Governor
b. Traction sheave
c. Door restrictor
d. Pit ladder
,Rationale: The traction sheave is driven by the hoisting machine and
grips the suspension ropes sufficiently to move the car and
counterweight.
5. What is the principal purpose of an elevator counterweight?
a. Increase door closing force
b. Reduce governor tension
c. Balance a substantial portion of the car load
d. Replace the car safety
Rationale: A counterweight balances the weight of the empty car plus
a specified portion of its rated load. This reduces the power required
by the hoisting machine.
6. Which device normally detects excessive elevator speed?
a. Encoder
b. Door lock
c. Governor
d. Push button
Rationale: The governor is specifically designed to sense excessive car
speed. At a predetermined tripping speed, it initiates the safety
sequence.
7. What is the purpose of a car safety?
, a. Control the elevator lights
b. Prevent door vibration
c. Stop or hold the car when a dangerous overspeed condition occurs
d. Increase travel speed
Rationale: The car safety is a mechanical safety device that engages
the guide rails when properly actuated, helping stop or restrain the
elevator car.
8. What is a major hazard associated with working in an elevator pit?
a. Excessive passenger traffic
b. Unexpected movement of elevator equipment
c. Excessive cab lighting
d. Low push-button voltage only
Rationale: Elevator equipment can move unexpectedly during
inspection, maintenance, or testing. Proper lockout/tagout, clearance,
communication, and safe work procedures are essential.
9. Before servicing energized elevator equipment, what should
normally be performed?
a. Increase motor speed
b. Remove all warning labels
