1) A contractor wants to raise the car speed from 100 100 fpm/125 fpm= 12"/ X
fpm to 125 fpm, it currently has a 12" sheave. What =15
is required?
2) A MOV (Metal Oxide Varistor) burns out. You Replace it with a larger
replace it, but cannot read voltage or resistance. MOV - 630
What should you do?
3) On a Ward-Leonard circuit the brake is set, but the Suicide Circuit - 425
motor is trying to slip through the brake. What is the
issue?
4) You have an old DC motor and are adding an SCR Leave the interpoles
drive, what do you do to 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 The relief valve is set too
full load. What is the issue? low - 815
6) Runby for a 1:1 hits the CWT buffer 4" below the 22" - 235
top landing. CWT runby should be set at 18". How
much should the ropes be shortened?
7) You need to work on a freight door retiring cam, you Door Operator disconnect
LOTO the main line but there is still power on the -535
cam. What circuit is still hot?
8) The contractor requests that the vertical center of a Adjust tie downs and wall
Rack and Pinion hoist be moved. How do you do ties - 850
this?
9) Working pressure on a Hydro is 400 PSI. What is the 400 x 150%= 600 PSI -
maximum relief valve setting? 815
10) What must be installed on a false care before Spring Loaded safeties -
operation? 110
11) There is slight arcing between the brush and None
commutator. What action must be taken? Note: Heavy arcing= light
brush pressure, Heavy
brush pressure=
mechanical wear
12) If rigging is roped 3:1 and a BEAM CLAMP is used 18,000lbs -210
, to lift a 6,000lb load. What is the beam capacity?
13) How much resistance is measured over a normally .2 Ohms- should be zero
closed switch? but will never be that low
14) A car traveling in the hoistway always stops at the traveling cable has a
same spot and blows a fuse. What causes this? cut/exposed wire or a
short - 515
15) How is a class 1 yearly buffer test preformed? Car at the bottom landing
and on inspection, jump
out direction and final
limits. With pit clear, run
down to compress the
buffers, buffers should
fully extend within 90
seconds.
Note: 5 yr is Full load, full
speed - 555
16) How many strain supports are required on a 350 ft 4
raceway? 1 every 100ft - 505-510
17) How is stainless steel drilled out? Slow speed and constant
pressure - 205
18) What is the required amout of retainer clips for At least 2. First clip being
wedge shackles and what is the spacing? 4 times the diameter of the
rope from the top of the
