resistance. What should you do? CORRECT ANSWER: Replace it with a larger MOV
630

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

What causes this CORRECT ANSWER: Traveling cable has a cut/exposed wire or a
short 515

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)

times the diameter of the rope above the first clip. 245
19. A 300ohm resistor burns out, but you don't have another one. How can you make
one? CORRECT ANSWER: 2-600ohm resistors in parallel is 300ohms. Resistance is
half of highest resistor in parallel circuit. 3-225ohm resistors in parallel is 75ohms. 345
20. When cutting laminated panels, which direction should the finish side face?
CORRECT ANSWER: Finish side facing the cutting edge of the tool. Blade will burr the
backside 255
21. How do you cut a finished floor? CORRECT ANSWER: Cutting blade away from
finished side 255
22. A 480vac stepdown 240vac transformer is connected to a 3 phase rectifier, what is
the output voltage? CORRECT ANSWER: 320vac 3 phase full wave = 1.33x output
voltage. 715
23) Car is loaded with 125% and sinks. Why? CORRECT ANSWER: Slipping through
the break
, 24. If you find a broken or missing barricade what should you do? CORRECT
ANSWER: Write up a formal inspection request

ANSWER: Broken Gear teeth. CWT derailment. Excessive wear/ crease the surface of
the tube 850
