1. During troubleshooting of a traction elevator, the motor
runs but the car does not move when a valid run
command is given. The brake is observed to remain
mechanically engaged. Which condition should be
investigated FIRST?
A. Increase the motor overload setting
B. Replace the governor rope
C. Verify the brake-release circuit and brake coil operation
D. Increase the counterweight mass
Rationale: A traction elevator cannot normally move while its
holding brake remains applied. The mechanic should first
determine whether the brake is receiving the proper electrical
release signal and whether the coil, linkage, and brake
mechanism operate correctly.
────────────────────────────────────────
2. An elevator repeatedly stops at different floors with the
car slightly above or below the landing level. The drive
system otherwise operates normally. Which component
should receive particular attention?
,A. Car-top inspection switch
B. Door restrictor
C. Leveling system and associated position sensors
D. Emergency alarm button
Rationale: Inconsistent floor leveling is commonly associated
with the position-sensing, leveling, or control circuitry that
determines the precise stopping position. The mechanic
should evaluate the sensors, magnets or targets, wiring, and
controller inputs before replacing unrelated components.
────────────────────────────────────────
3. A mechanic is performing work inside an elevator
hoistway. Which practice provides the most appropriate
protection against unexpected movement of the car?
A. Place the elevator on independent service
B. Turn off only the cab lights
C. Apply the required lockout/tagout and verify zero-energy
conditions before beginning hazardous work
D. Leave the doors open at the nearest landing
Rationale: Service controls such as independent service do not
substitute for proper energy isolation when hazardous work is
being performed. Lockout/tagout and verification are
intended to prevent unexpected energization or movement
from electrical, mechanical, hydraulic, or other stored-energy
sources.
────────────────────────────────────────
4. A traction elevator's drive sheave shows significant wear
in the rope grooves. What is the primary concern?
,A. Increased cab lighting voltage
B. Reduced door-opening speed
C. Loss of proper traction and abnormal rope wear
D. Increased alarm-bell volume
Rationale: The geometry and condition of the drive sheave
grooves are critical to the relationship between the hoisting
ropes and sheave. Excessive wear can alter rope seating,
increase slippage or wear, and compromise reliable traction.
────────────────────────────────────────
5. A mechanic notices that an elevator door begins closing
immediately after the reopening device is interrupted,
even though a passenger is still within the doorway.
Which system should be investigated?
A. Counterweight guide shoes
B. Door protective and reopening devices
C. Governor overspeed switch
D. Machine-room ventilation
Rationale: Door reopening devices are intended to detect an
obstruction or passenger in the doorway and initiate
reopening or prevent closing. A malfunctioning sensor,
detector, wiring circuit, or controller input can cause unsafe
door behavior.
────────────────────────────────────────
6. A traction elevator begins making a rhythmic scraping
noise that increases with car movement. Inspection
reveals abnormal wear on one set of guide surfaces.
What is the most appropriate diagnostic approach?
, A. Adjust the governor to compensate
B. Replace the car operating panel
C. Inspect guide shoes, guide rails, alignment, lubrication
where applicable, and related mounting components
D. Increase the door-closing force
Rationale: A movement-related scraping noise originating
near the guide system can result from worn shoes, rail
contamination, poor alignment, improper clearances, or
damaged mounting components. The mechanic should
identify the physical source rather than compensate through
unrelated adjustments.
────────────────────────────────────────
7. During inspection of a hydraulic elevator, the car slowly
settles downward while stopped at a floor. No door
movement is involved. Which condition is most
relevant?
A. Worn door rollers
B. Internal leakage in the hydraulic system or control valve
C. Damaged car operating station
D. Defective hall lantern
Rationale: Unintended downward movement of a hydraulic
elevator while stationary can be associated with leakage
through the control valve, cylinder, packing, or related
hydraulic components. Proper diagnosis requires determining
where pressure is being lost.
