A contractor wants to raise the car speed from 100fpm to 125fpm, it currently has a 12" sheave. What
sheave is required? - correct answer-
Diam=12" 12/4=3" 25fpm=3" 100fpm + 25fpm= 12"+3"= 15" sheave
A MOV (Metal Oxide Varistor) burns out. You replace it, but cannot read voltage or resistance. What sh
ould you do? - correct answer-Replace it with a larger MOV
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
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 a
re the 3 resistors. Everything else remains the same
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
Runby for a 1:1 hits the CWT buffer 4" below the top landing. CWT runby should be set at 18". How m
uch should the ropes be shortened? - correct answer-22"
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
The contractor requests that the vertical center of a Rack and Pinion hoist be moved. How do you do t
his? - correct answer-Adjust Tie Downs and Wall Ties
Working pressure on a Hydro is 400psi. What is the maximum relief valve setting? - correct answer-
400psi x 150%= 600psi
,What must be installed on a false car before operation? - correct answer-Spring Loaded Safeties.
There is slight arcing between the brush and commutator. What action must be taken? -
correct answer-None.
Heavy arcing=Light brush pressure. Heavy bush pressure=mechanical wear
If rigging gear is roped 3:1 and a BEAM CLAMP is used to liſt a 6,000lb load. What is the beam capacity
? - correct answer-
18,000lbs. 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
How much resistance is measured over a normally closed switch? - correct answer-
1.2ohms. 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
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 t
o compress buffers, buffers should fully extend within 90 seconds.
