COMPLETE ELEVATOR MECHANIC LICENSE
PREP 2026 VERIFIED EXAM QUESTIONS WITH
FULL EXPLANATIONS
This comprehensive study resource features meticulously
verified multiple-choice questions with full, step-by-step
explanations designed to mirror the actual exam. It covers
critical mechanical math, safety code compliance, advanced
electrical troubleshooting, and rigging techniques essential for
certification success. Perfect for rapid review, this guide
guarantees mastery of key concepts to help you pass your
licensing test on the very first try.
1. What is the primary purpose of a governor in an
elevator system?
A) To control the cab doors
B) To monitor and limit elevator overspeed
C) To regulate the main power supply
D) To smooth out the ride quality
Answer: B
Rationale: The governor is a critical safety device
that detects when an elevator is traveling faster
than its rated speed. If overspeed occurs, it trips the
safety switch and mechanically engages the car
safeties to stop the cab.
,2. Which type of rope is most commonly used for
elevator hoisting due to its balance of flexibility and
strength?
A) Left lay synthetic rope
B) Right regular lay carbon fiber
C) Right regular lay steel wire rope
D) Lang lay copper wire rope
Answer: C
Rationale: Right regular lay steel wire rope is the
industry standard for hoist ropes because its
construction resists twisting, offers high tensile
strength, and provides excellent flexibility over
sheaves.
3. In a hydraulic elevator, what component prevents oil
from flowing back into the reservoir from the
cylinder?
A) Control valve
B) Check valve
C) Scavenger pump
D) Muffler
Answer: B
Rationale: The check valve allows hydraulic fluid to
flow in only one direction (into the cylinder) and
seals automatically to prevent fluid backflow,
maintaining the elevator's position when stopped.
,4. What is the minimum clearance required between
the car sill and the landing sill according to ASME
A17.1?
A) 0.25 inches
B) 0.5 inches
C) 1.25 inches
D) 1.5 inches
Answer: B
Rationale: ASME A17.1 safety standards dictate
that the running clearance between the car
platform sill and the hoistway landing sill must be
no less than 0.5 inches (13 mm) to prevent
mechanical interference.
5. Which electrical device protects an elevator motor
from damage caused by an overload condition over
an extended period?
A) Circuit breaker
B) Thermal overload relay
C) Fuse
D) Isolation transformer
Answer: B
Rationale: Thermal overload relays are designed to
mimic the heating profile of the motor windings.
They trip and cut power when sustained excess
current threatens to burn out the motor.
, 6. What mechanical tool is specifically used to verify
that elevator guide rails are perfectly plumb during
installation?
A) Laser level and rail alignment gauge
B) Dial indicator
C) Tram string and caliper
D) Spirit level and plumb bob
Answer: A
Rationale: Modern rail installation relies on laser
levels combined with specialized rail alignment
gauges to ensure absolute vertical precision
(plumb) over long vertical hoistway distances.
7. What type of safety is required for elevators
operating at speeds greater than 150 feet per
minute (fpm)?
A) Type A instantaneous safeties
B) Type B wedge-clamp safeties
C) Type B progressive safeties
D) Type C oil-buffer safeties
Answer: C
Rationale: For speeds above 150 fpm, Type B
progressive safeties are mandatory because they
apply a continuous, gradual braking force to bring
the car to a safe stop without injurious deceleration
forces.
