Consist of 200+ Questions and Answers
1. If rigging gear is roped 3:1 and a BEAM CLAMP is used to lift a 6,000lb load.
What is the beam capacity
Ans>> 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
2. What are the consequences of misaligned joints on a Rack and Pinion
Ans>> -
Broken Gear teeth. CWT derailment. Excessive wear/ crease the surface of the tube
3. There is a noise coming from a freight door. The sheave is moving, but the
chain is not. What is the problem
Ans>> Oil on the drive chain
1/9
,4. What is the effect when you change a sling angle from 60 degrees to 30
degrees
Ans>> More tension, less capacity. Any angle 30 or less is dangerous
5. Generator runs at 600rpm and has 4 poles, what is the output frequency?-
: 20hz
600/60=10 10x2=20 RPM 60 x frequency / pole/2
6. How many wires are needed for the following circuit? Exclude spares. BCE-
--SPI/BCD---SP2/BCD---SP4/BCD---UR1/BCE---UR2/BCE---DR1/CRE---
DR2/GRD: 11 wires. You do not need the duplicates
7. How must a 9 lead 480/240 motor be wired for High Voltage
Ans>> L1(1) L2(2) L3(3) Low Voltage L1(1-7) L2(2- 8) L3(3-9) 7-4 8-6 9-5 4 5 6
+
120v 0-------0 R2 A R1 GRD
8. There is voltage at the switch, but none at A, what is wrong
Ans>> Open at R2 or R1
9. The close door limit switch is not working, you have power at points 35-8, no
voltage at 1-S2 why
2/9
, Ans>> Door limit switch malfunction
10. The step level switch on an escalator has been tripped, where do you check
Ans>> Upper and Lower Truss assemblies, trips if step sags more than 1/8th inch
11. A motor needs a sleeve bearing replaced, what type of bearing do you
need
Ans>> Friction bearing AKA Sleeve bearing.
Anti-Friction Bearing AKA Ball bearing
12. What type of safeties are required on a 300fpm car
Ans>> Type B wedge clamp
13. What stopping devices are required on vertical platforms
Ans>> 2 pan switches. 15lbs max pressure
14. What are the most common features of Load Weigh
Ans>> Control generator field and Inside express operation
15. At what distance from closed does the gate switch operate
Ans>> 2 inches
3/9
