Practice1
1. A contractor wants to raise the car speed from 100fpm to 125fpm, it cur-
rently has a 12" sheave.What sheave is required
Answer: Diam=12" 12/4=3" 25fpm=3" 100fpm + 25fpm= 12"+3"= 15" sheave
2. A MOV (Metal Oxide Varistor) burns out.You replace it, but cannot read voltage or resistance.What should
you do
Answer: Replace it with a larger MOV
3. On a Ward-Leonard circuit the break is set, but the motor is trying to slip through the break.What is the
issue
Answer: Suicide Circuit
4. You have an old DC motor and are adding an SCR drive, what do you do to the interpoles
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
5. A hydro runs up with no load, but will not run with a full load.What is the issue
Answer: The relief valve is set too low
6. 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
Answer: 22"
7. 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
Answer: Door Operator Disconnect/ Main Line Disconnect
8. The contractor requests that the vertical center of a Rack and Pinion hoist be moved. How do you do this
Answer: Adjust Tie Downs and Wall Ties
9. Working pressure on a Hydro is 400psi.What is the maximum relief valve setting
Answer: 400psi x 150%= 600psi
10. What must be installed on a false car before operation
Answer: Spring Loaded Safeties.
11. There is slight arcing between the brush and commutator.What action must be taken
Answer: None.
Heavy arcing=Light brush pressure. Heavy bush pressure=mechanical wear
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
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
13. How much resistance is measured over a normally closed switch
Answer: -
1.2ohms. should be zero, but will never be that low
14. A car traveling in the hoistway always stops at the same spot and blows a fuse.What causes this
Answer: Traveling cable has a cut/exposed wire or a short
15. How is a class 1 yearly buffer test preformed
Answer: Car at bottom 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.
5yr: Full load Full speed
CWT: Full speed Empty
16. How many strain supports are required on a 350ft raceway
Answer: 4.1 every 100ft
17. How is stainless steel drilled out
Answer: Slow speed and constant pressure
18. What is the required amount of retainer clips for wedge shackles and what is the spacing
Answer: Minimum 2 clips. 1st at a maximum 4x the diameter of the rope 2nd at a maximum 8x the diameter above
the 1st clip
19. A 300ohm resistor burns out, but you don't have another one. How can you make one
Answer: 2 600ohm resistors in parallel is 300ohms.Resistance is half of highest resistor in parallel circuit.
3 225ohm resistors in parallel is 75ohms.
20. When cutting laminated panels, which direction should the finish side face
, Answer: Finish side facing the cutting edge of the tool. Blade will burr the backside
21. How do you cut a finished floor
Answer: Cutting blade away from finished side
22. A 480vac stepdown 240vac transformer is connected to a 3 phase rectifier, what is the output voltage
Answer: 320vac
3 phase full wave = 1.33x output voltage
23. A car is loaded with 125% and sinks, why
Answer: Slipping through the break
24. If you find a broken or missing barricade what should you do
Answer: Write up a formal inspection request
25. What are the consequences of misaligned joints on a Rack and Pinion
Answer: -
Broken Gear teeth. CWT derailment. Excessive wear/ crease the surface of the tube
26. A dumbwaiter is 9sqft in area, 4ft high, and capacity is 13.9lb/ft3.What is total capacity
Answer: 9 x 4 x 13.9= 500lbs Max capacity
27. You must enter a pit with a toxic atmosphere, how do you proceed
Answer: Fol- lowing proper OSHA procedure with proper training and PPE
28. When changing a 1:1 car rated at 600fpm and 2,000lb capacity to a 2:1, what are the new ratings
Answer: 300fpm 4,000lbs capacity
