1. A contractor wants to raise the car speed from 100fpm to 125fpm, it currently has a 12"
sheave. What sheave is required?
CORRECT ANSWER
100fpm / 125fpm = 12" / X= 15"
2. A MOV (Metal Oxide Varistor) burns out. You replace it, but cannot read voltage or
resistance. What should you do?
CORRECT ANSWER
Replace it with a larger MOV 630
3. On a Ward-Leonard circuit the break is set, but the motor is trying to slip through the
break. What is the issue?
CORRECT ANSWER
Suicide Circuit 425
4. You have an old DC motor and are adding an SCR drive, what do you do to the interpoles?
CORRECT 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.

,5. A hydro runs up with no load, but will not run with a full load. What is the issue?
CORRECT ANSWER
The relief valve is set too low 815
6. 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?
CORRECT ANSWER
22" 235
7. 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?
CORRECT ANSWER
Door Operator Disconnect/ Main Line Disconnect 535
8. The contractor requests that the vertical center of a Rack and Pinion hoist be moved. How
do you do this?
CORRECT ANSWER
Adjust Tie Downs and Wall Ties 850
9. Working pressure on a Hydro is 400psi. What is the maximum relief valve setting?
CORRECT ANSWER
400psi x 150%= 600psi 815

,10. What must be installed on a false car before operation?
CORRECT ANSWER
Spring Loaded Safeties 110
11. There is slight arcing between the brush and commutator. What action must be taken?
CORRECT ANSWER
None
Note: Heavy arcing=Light brush pressure, Heavy bush pressure=mechanical wear 430
12. If rigging gear is roped 3:1 and a BEAM CLAMP is used to lift a 6,000lb load. What is the
beam capacity requirement?
CORRECT ANSWER
18,000lbs.
Note: 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 210
13. How much resistance is measured over a normally closed switch?
CORRECT ANSWER
1.2ohms. should be zero, but will never be that low
14. A car traveling in the hoistway always stops at the same spot and blows a fuse. What
causes this
CORRECT ANSWER
Traveling cable has a cut/exposed wire or a short 515

, 15. How is a class 1 yearly buffer test preformed?
CORRECT 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.
Note: 5yr: Full load Full speed CWT: Full speed Empty 555 (may be 60 on test)
16. How many strain supports are required on a 350ft raceway?
CORRECT ANSWER
4. 1 every 100ft 505-510
17) How is stainless steel drilled out?
CORRECT ANSWER
Slow speed and constant pressure 205
18. What is the required amount of retainer clips for wedge shackles and what is the
spacing?
CORRECT ANSWER
At least 2. First clip being maximum 4 times the diameter of the rope from the top of the
shackle, and the second clip is maximum 8 times the diameter of the rope above the first
clip. 245
