MECHANICS EXAM NEIEP (2026/2027) QUESTIONS WITH
VERIFIED CORRECT ANSWERS || 100% GUARANTEED
PASS UPDATED VERSION
1. What is the primary purpose of Lockout/Tagout (LOTO) procedures in
an elevator hoistway?
ANSWERS> To ensure that hazardous energy sources are isolated and
rendered inoperative before any mechanical or electrical work begins,
protecting the mechanic from unexpected energization or startup.
2. Under ASME A17.1, what is the maximum permitted tripping speed
of a Type B (progressive) safety in relation to the rated speed of the
elevator?
ANSWERS> 125% of the rated speed.
3. When working on an escalator, what must be done before removing
any guards or performing maintenance?
ANSWERS> The main disconnect switch must be locked out, tagged out,
and the stop switch at the upper and lower starting points must be
activated.
4. What is the function of the under-counterweight safety device?
ANSWERS> To stop the counterweight in the event of car overspeed or
free fall in the up direction, preventing the counterweight from crushing
the car.
, 5. Ohm's Law states that voltage (E) equals current (I) multiplied by
resistance (R). What is the formula to find Resistance (R)?
ANSWERS> R = E / I (Resistance = Voltage / Current).
6. What is the purpose of the compensation chain or rope on a traction
elevator?
ANSWERS> To balance the weight of the hoist ropes as the car travels,
ensuring consistent traction and motor load between the up and down
runs.
7. What is the minimum breaking strength of a wire rope sling used for
hoisting materials, relative to its working load?
ANSWERS> The design factor must be a minimum of 5 (breaking
strength is 5 times the working load).
8. In a Type ACME (geared traction) machine, what component
connects the motor to the worm shaft?
ANSWERS> The flexible coupling.
9. What is the function of the phase reversal relay in an elevator
controller?
