Elevator Mechanic Exam (2026) |
Guaranteed Success
• A MOV (Metal Oxide Varistor) burns out. You replace it, but cannot
read voltage or resistance. What should you do? -✓✓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? -✓✓Suicide Circuit
• You have an old DC motor and are adding an SCR drive, what do you
do to the interpoles? -✓✓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? -✓✓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? -
✓✓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? -
✓✓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? -✓✓Adjust Tie Downs and Wall
Ties
,• Working pressure on a Hydro is 400psi. What is the maximum relief
valve setting? -✓✓400psi x 150%= 600psi
• What must be installed on a false car before operation? -✓✓Spring
Loaded Safeties.
• There is slight arcing between the brush and commutator. What action
must be taken? -✓✓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? -✓✓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? -
✓✓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? -✓✓Traveling cable has a cut/exposed
wire or a short
• How is a class 1 yearly buffer test preformed? -✓✓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? -✓✓4-1
every 100ft
, • How is stainless steel drilled out? -✓✓Slow speed and constant
pressure
• What is the required amount of retainer clips for wedge shackles and
what is the spacing? -✓✓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? -✓✓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? -✓✓Finish side facing the cutting edge of the tool. Blade will burr
the backside
• How do you cut a finished floor? -✓✓Cutting blade away from
finished side
• A 480vac stepdown 240vac transformer is connected to a 3 phase
rectifier, what is the output voltage? -✓✓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? -✓✓Slipping through the
break
• If you find a broken or missing barricade what should you do? -
✓✓Write up a formal inspection request
