1
00:00:01,266 --> 00:00:04,099
Industrial machinery works around the clock

2
00:00:04,100 --> 00:00:06,100
to manufacture food products,

3
00:00:06,100 --> 00:00:07,500
generate power,

4
00:00:07,500 --> 00:00:09,933
and move suitcases at the airport.

5
00:00:09,933 --> 00:00:11,866
Industrial machinery maintenance workers,

6
00:00:11,866 --> 00:00:13,499
mechanics, and millwrights

7
00:00:13,500 --> 00:00:15,233
make sure industrial machinery

8
00:00:15,233 --> 00:00:17,299
stays on the job.

9
00:00:17,300 --> 00:00:18,700
Machinery maintenance workers

10
00:00:18,700 --> 00:00:20,666
do basic maintenance and repairs,

11
00:00:20,666 --> 00:00:23,166
such as cleaning and lubricating machinery,

12
00:00:23,166 --> 00:00:25,232
performing basic diagnostic tests,

13
00:00:25,233 --> 00:00:27,666
and testing damaged parts.

14
00:00:27,666 --> 00:00:30,132
Using computerized diagnostic equipment

15
00:00:30,133 --> 00:00:31,799
and expertise,

16
00:00:31,800 --> 00:00:34,300
industrial machinery mechanics detect and fix

17
00:00:34,300 --> 00:00:35,933
mechanical problems;

18
00:00:35,933 --> 00:00:38,399
just listening to a machine’s vibration,

19
00:00:38,400 --> 00:00:40,233
they can distinguish a worn belt

20
00:00:40,233 --> 00:00:42,399
from a weak motor bearing.

21
00:00:42,400 --> 00:00:44,733
Millwrights install and disassemble

22
00:00:44,733 --> 00:00:46,166
industrial machines

23
00:00:46,166 --> 00:00:48,132
as well as conduct repairs.

24
00:00:48,133 --> 00:00:50,366
They often move machines within a facility,

25
00:00:50,366 --> 00:00:52,132
carefully categorizing

26
00:00:52,133 --> 00:00:54,466
and sequencing every part.

27
00:00:54,466 --> 00:00:56,266
They use cranes and forklifts

28
00:00:56,266 --> 00:00:59,099
to bring the heavy parts to the new location.

29
00:00:59,100 --> 00:01:00,900
In addition to hand tools,

30
00:01:00,900 --> 00:01:02,266
these workers use welding

31
00:01:02,266 --> 00:01:03,666
and cutting equipment,

32
00:01:03,666 --> 00:01:06,066
and precision-measuring devices.

33
00:01:06,066 --> 00:01:08,566
Because of the high risk of injury on the job,

34
00:01:08,566 --> 00:01:10,999
safety precautions and protective equipment

35
00:01:11,000 --> 00:01:13,900
such as hardhats, steel-toed shoes,

36
00:01:13,900 --> 00:01:16,400
and earplugs are essential.

37
00:01:16,400 --> 00:01:18,233
Industrial machinery mechanics

38
00:01:18,233 --> 00:01:19,833
and maintenance workers

39
00:01:19,833 --> 00:01:22,199
typically work regular, full-time hours,

40
00:01:22,200 --> 00:01:24,200
although overtime is common,

41
00:01:24,200 --> 00:01:26,000
especially for mechanics.

42
00:01:26,000 --> 00:01:28,833
Millwrights may have more variable schedules

43
00:01:28,833 --> 00:01:30,933
with downtime between projects,

44
00:01:30,933 --> 00:01:33,166
as they usually work on a contract basis

45
00:01:33,166 --> 00:01:35,932
to assemble or disassemble machines.

46
00:01:35,933 --> 00:01:38,699
While all 3 need a high school education

47
00:01:38,700 --> 00:01:40,300
to enter the field,

48
00:01:40,300 --> 00:01:41,933
machinery maintenance workers

49
00:01:41,933 --> 00:01:44,433
typically receive on-the-job training;

50
00:01:44,433 --> 00:01:46,199
industrial machinery mechanics

51
00:01:46,200 --> 00:01:47,866
need a year or more of training;

52
00:01:47,866 --> 00:01:50,132
and most millwrights learn their skills

53
00:01:50,133 --> 00:01:51,899
in a 4-year apprenticeship—

54
00:01:51,900 --> 00:01:53,533
although an associate’s degree

55
00:01:53,533 --> 00:01:56,633
in industrial maintenance may suffice.
