Introduction:
The purpose of this exam is to assess the comprehensive professional knowledge required for elevator
constructors working with escalator and moving walk systems. This evaluation covers foundational
mechanical and electrical theory, rigorous safety standard applications, and regulatory code
requirements. Spanning a diverse array of technical concepts, the assessment is structured with
multiple-choice and complex scenario-based questions that test diagnostic critical thinking. Candidates
are evaluated on their skills regarding installation, maintenance, and structural troubleshooting, with a
heavy emphasis on real-world application, professional ethics, and operational safety decision-making
necessary to ensure public safety and optimal equipment performance.
Question 1
When aligning an escalator truss during a modernization or initial installation, what instrument is primarily
used to ensure the centerline of the truss matches the building centerline?
A. Laser alignment tool or plumb bob
B. Digital protractor
C. Dial indicator
,D. Dial caliper
Correct answer: 🟢 A. Laser alignment tool or plumb bob
🔴 RATIONALE: A laser alignment tool or a traditional plumb bob is utilized to establish and verify that
the escalator truss centerline aligns precisely with the building's structural centerline marks.
Question 2
According to ASME A17.1, what is the maximum allowable angle of inclination for an escalator installed
in a commercial building?
A. 27 degrees
B. 30 degrees
C. 35 degrees
D. 40 degrees
Correct answer: 🟢 B. 30 degrees
🔴 RATIONALE: Code mandates that the maximum angle of inclination for an escalator cannot exceed
30 degrees relative to the horizontal plane to prevent passenger falls.
Question 3
An escalator step has been damaged by a foreign object caught at the lower combplate. Before
replacing the step, which safety item must be checked and manual reset performed if tripped?
A. Broken drive chain switch
B. Handrail speed monitoring switch
C. Comb-step impact device switch
D. Step upthrust switch
Correct answer: 🟢 C. Comb-step impact device switch
🔴 RATIONALE: The comb-step impact device is designed to detect horizontal or vertical forces
resulting from objects trapping between the step and the combplate, cutting power to the drive motor.
Question 4
,What is the function of the step upthrust switch located at the upper and lower inclines of an escalator
track system?
A. To monitor the speed variation of the steps relative to the handrail
B. To detect if a step has been displaced vertically before entering the combplate
C. To measure the wear on the step chain rollers
D. To cut power if the main drive chain breaks
Correct answer: 🟢 B. To detect if a step has been displaced vertically before entering the combplate
🔴 RATIONALE: The step upthrust switch identifies abnormal vertical movement or displacement of the
step, stopping the escalator to prevent structural jamming or passenger injury at the landings.
Question 5
During a routine maintenance inspection, you observe that the escalator handrail is running slower than
the steps. Which component is likely slipping or requires adjustment?
A. The step chain tensioner
B. The main drive gear
C. The handrail drive friction wheels or chains
D. The auxiliary brake pads
Correct answer: 🟢 C. The handrail drive friction wheels or chains
🔴 RATIONALE: Handrails are driven by friction drive systems synced to the main drive. Slippage or
wear in the handrail drive friction wheels or drive chains causes the handrail to lose synchronicity with
step speed.
Question 6
What is the primary mechanical purpose of the skirt panels on an escalator?
A. To support the handrail guide system
B. To provide structural rigidity to the truss upper chords
C. To close the side gap between the moving steps and the stationary balustrade
D. To cover the electrical wiring channels alongside the incline
, Correct answer: 🟢 C. To close the side gap between the moving steps and the stationary balustrade
🔴 RATIONALE: Skirt panels form the side boundaries of the escalator interior, minimizing the clearance
gap between the moving steps and stationary components to prevent entrapment.
Question 7
What is the maximum allowable clearance between an escalator step and the adjacent skirt panel on one
side, according to ASME A17.1 safety code?
A. 3/16 inch
B. 1/4 inch
C. 3/8 inch
D. 1/2 inch
Correct answer: 🟢 A. 3/16 inch
🔴 RATIONALE: The safety code specifies that the horizontal clearance between the edge of a step and
the adjacent skirt panel must not exceed 3/16 inch to minimize entrapment hazards.
Question 8
While inspecting an escalator drive system, you notice the main drive chain has excessive slack. What is
the correct method for correcting this condition?
A. Removing links from the step chain
B. Shifting the position of the main drive motor or adjusting the chain tension idler sprocket
C. Replacing the step rollers with larger diameter rollers
D. Adjusting the upper track radius curves
Correct answer: 🟢 B. Shifting the position of the main drive motor or adjusting the chain tension idler
sprocket
🔴 RATIONALE: Main drive chain slack is corrected by moving the adjustable motor base mountings or
configuring the designated drive chain tension idler sprocket assembly.
