QUESTIONS WITH VERIFIED CORRECT
ANSWERS 100% GUARANTEED PASS
<UPDATED VERSION>
** An MOV burns out, you replace it but cannot read voltage or
resistance. What should you do? - Answer ✔✔ - Replace it with a
larger one (630)
* On a Ward-Leonard circuit, the brake is set but the motor is trying to
slip through the brake. What circuit is the issue? - Answer ✔✔ -
Suicide circuit (425)
** A Hydro runs up with no load but does not run up with a full load.
What is the issue? - Answer ✔✔ - The relief valve is set too low (805)
** Runby for a 1:1 car hits the CWT buffer 4" below the top landing.
The CWT runby should be set at 18". How much should the ropes be
shortened? - Answer ✔✔ - 22" for 1:1.
For a 2:1 with the same issue is 44".
** You need to work on a freight door retiring cam. You LOTO the
mainline disconnect but there is still power to the cam. What circuit is
still hot? - Answer ✔✔ - Mainline disconnect (535)
** The contractor requests that the vertical center of the Rack and
Pinion hoist be moved. How is this accomplished? - Answer ✔✔ -
Adjust Tie downs/Wall ties (805)
,** Working pressure on a Hydro is 400 PSI. What is the correct Relief
Valve Setting? - Answer ✔✔ - 600 PSI Max. (805)
400 psi x 150% = 600 psi
** A contractor wants to raise the car speed from 100 FPM to 125 FPM.
It currently has a 12" sheave. What size sheave is required? - Answer
✔✔ - 15"
(125 /100 = 1.25 1.25 x 12 = 15)
** There is slight arcing at the Brushes and Commutator. What actions
must be taken? - Answer ✔✔ - None. (430)
"Heavy arcing is due to light brush pressure. Mechanical wear indicates
heavy brush pressure.
** How much resistance is normally measured across a normally closed
switch ? - Answer ✔✔ - 1.2 ohms or 1 to 2 ohms
** A car traveling in the hoistway always stops at the same point and
blows a fuse. What is the problem? - Answer ✔✔ - Traveling cable has
a cut or short
** How is a Class 1 (yearly) buffer test performed? - Answer ✔✔ - At
slow speed and the buffer must return in 90 seconds. (555) *(60
seconds is acceptable) (90 seconds is code)
5 year test (Class 5) is car at rated load and speed. Buffer must return in
90 seconds. CWT at rated speed and buffer must return in 90 seconds.
** How many Strain Supports are required on a 350' raceway? - Answer
✔✔ - 4
One for every 100'
, ** How is Stainless steel drilled out? - Answer ✔✔ - Slow speed and
constant pressure (205)
** What are the required amount of clips for Wedge Shackles and what
is their spacing? - Answer ✔✔ - At least 2, with the first being 4 times
the diameter of the rope from the top of shackle.
Second is 8 times the diameter of the rope from the first.
** Car is loaded with 125% and sinks. Why? - Answer ✔✔ - Slipped
through the brake.
** A 300 Ohm resistor burns out. You don't have a 300 Ohm resistor to
replace it. What can you use to make up the resistor? - Answer ✔✔ - 2
600 Ohms resistors in Parallel. "The resistance is half of the highest
rating in a parallel circuit.
3, 225 Ohm resistors in parallel equal 75 Ohms.
** A 480 VAC Step Down Transformer is connected to a 3 phase
rectifier. What will the output be? - Answer ✔✔ - 320 VDC
480 - 33.33% = 320
** If you find a broken or missing barricade, what do you do? - Answer
✔✔ - Write up a formal inspection request.
** If a Dumbwaiter has 9 square feet in Area,
4 ' High and the rated Capacity is 13.9 lb/ft3, what is the total capacity?
- Answer ✔✔ - 500 lb/ft3.
"The area of a Dumbwaiter is 9 sq' max and is 4' High. Multiply that by
13.9.
