ELEVATOR MECHANIC EXAM 2026 FINAL
PAPER SOLVED ITEMS ACCURATE MARKING
◉ A MOV (Metal Oxide Varistor) burns out. You replace it, but cannot
read voltage or resistance. What should you do? Answer: Check
circuit voltage
◉ On a Ward-Leonard circuit the break is set, but the motor is trying
to slip through the break. What is the issue? Answer: Suicide Circuit
◉ You have an old DC motor and are adding an SCR drive, what do
you do to the interpoles? Answer: Leave the interpoles alone. When
adding a SCR drive to the generator, the series loop is removed, as
are the 3 resistors. Everything else remains the same
◉ A hydro runs up with no load, but will not run with a full load.
What is the issue? Answer: The relief valve is set too low
◉ Runby for a 1:1 hits the CWT buffer 4" below the top landing. CWT
runby should be set at 18". How much should the ropes be
shortened? Answer: 1:1-22"
2:1-44"
,◉ You need to work on a freight door retiring cam, you LOTO the
main line but there is still power on the cam. What circuit is still hot?
Answer: Door circuit is still hot, Door Operator Disconnect/ Main
Line Disconnect
◉ The contractor requests that the vertical center of a Rack and
Pinion hoist be moved. How do you do this? Answer: Adjust Tie
Downs and Wall Ties
◉ Working pressure on a Hydro is 400psi. What is the maximum
relief valve setting? Answer: 400psi x 150%= 600psi
◉ What must be installed on a false car before operation? Answer:
Spring Loaded Safeties.
◉ There is slight arcing between the brush and commutator. What
action must be taken? Answer: None.
Heavy arcing=Light brush pressure. Heavy bush
pressure=mechanical wear
◉ If rigging gear is roped 3:1 and a BEAM CLAMP is used to lift a
6,000lb load. What is the beam capacity? Answer: 18,000lbs. Beam
capacity is cut in half with use of clamp, when rigging all blocks,
rope, and clamps will be Equal to the lowest load rating
,◉ How much resistance is measured over a normally closed switch?
Answer: 1.2ohms. should be zero, but will never be that low
◉ A car traveling in the hoistway always stops at the same spot and
blows a fuse. What causes this? Answer: Traveling cable has a
cut/exposed wire or a short
◉ How is a class 1 yearly buffer test preformed? Answer: Car at
bottom landing and on inspection, jump out direction and final
limits. With pit clear, run down to compress buffers, buffers should
fully extend within 90 seconds.
5yr: Full load Full speed
CWT: Full speed Empty
◉ How many strain supports are required on a 350ft raceway?
Answer: 4-1 every 100ft
◉ How is stainless steel drilled out? Answer: Slow speed and
constant pressure
◉ What is the required amount of retainer clips for wedge shackles
and what is the spacing? Answer: Minimum 2 clips. 1st at a
maximum 4x the diameter of the rope
2nd at a maximum 8x the diameter above the 1st clip
, ◉ A 300ohm resistor burns out, but you don't have another one.
How can you make one? Answer: 2 600ohm resistors in parallel is
300ohms. Resistance is half of highest resistor in parallel circuit.
3 225ohm resistors in parallel is 75ohms.
◉ When cutting laminated panels, which direction should the finish
side face? Answer: Finish side facing the cutting edge of the tool.
Blade will burr the backside
◉ How do you cut a finished floor? Answer: Cutting blade away from
finished side
◉ A 480vac stepdown 240vac transformer is connected to a 3 phase
rectifier, what is the output voltage? Answer: 320vac
3 phase full wave = 1.33x output voltage of transformer
1 phase full wave= .9 x output voltage of transformer
◉ A car is loaded with 125% and sinks, why? Answer: Slipping
through the break
◉ If you find a broken or missing barricade what should you do?
Answer: Write up a formal inspection request
