When changing a 1:1 car rated at 600fpm and 2,000lb capacity to a 2:1, what are
the new ratings? - CORRECT ANSWER-300 fpm with 4000lbs capacity. Half the
speed and double the capacity.
A vertical platform lift has a clearance of 1 inch. How much will it have to move to
meet code? - CORRECT ANSWER-Move in 1/4 inch. Code is 3/4 in
A car weighs 2500lbs with a capacity of 2500lbs, The CWT is weighted 40% , how
much is the motor lifting when the car is fully loaded? - CORRECT ANSWER-
2500 (CAR) + 1000 ( 40%)= 3500lbs
5000-3500= 1500lbs lifted by the machine - 240
How must Oxygen and Acetylene tanks be stored? - CORRECT ANSWER-
Vertically, 12 feet apart, or on a cart with a ½ hour fire barrier between them
What is code for sill to sill distance? - CORRECT ANSWER-Minimum- 1/2 in
,Maximum- 1-1/2 in - 525
A contractor wants to raise the car speed from 100 fpm to 125 fpm, it currently
has a 12" sheave. What is required? - CORRECT ANSWER-100 fpm/125 fpm=
12"/ X =15
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
On a Ward-Leonard circuit the brake is set, but the motor is trying to slip through
the brake. What is the issue? - CORRECT ANSWER-Suicide Circuit - 425
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

CORRECT ANSWER-The relief valve is set too low - 815
,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

moved. How do you do this? - CORRECT ANSWER-Adjust tie downs and wall
ties - 850
Working pressure on a Hydro is 400 PSI. What is the maximum relief valve
setting? - CORRECT ANSWER-400 x 150%= 600 PSI - 815
What must be installed on a false care before operation? - CORRECT ANSWER-
Spring Loaded safeties - 110
There is slight arcing between the brush and commutator. What action must be
taken? - CORRECT ANSWER-None
Note: Heavy arcing= light brush pressure, Heavy brush pressure= mechanical wear
, If rigging is roped 3:1 and a BEAM CLAMP is used to lift a 6,000lb load. What is the
beam capacity? - CORRECT ANSWER-18,000lbs -210
How much resistance is measured over a normally closed switch? - CORRECT
ANSWER-.2 Ohms- 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? - CORRECT ANSWER-traveling cable has a cut/exposed wire
or a short - 515
How is a class 1 yearly buffer test preformed? - CORRECT ANSWER-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
