ANSWERS EXPERT VERIFIED /ALREADY GRADED A+
1. The primary federal agency responsible for enforcing safety and health regulations in the
workplace is....ANSWER....the Occupational Safety and Health Administration (OSHA).
2. The condition where a crane's load suddenly stops falling, causing a dynamic force to be
transferred into the crane's structure and supporting system, is known as....ANSWER....shock
loading.
3. A crane's load chart does NOT typically provide capacity information based
on....ANSWER....wind speed at the load.
4. The primary purpose of a jib is to....ANSWER....increase the crane's hook height and reach.
5. Before making a lift, the operator must ensure the load is....ANSWER....properly rigged and
balanced.
6. The term "two-blocking" refers to....ANSWER....when the hook block contacts the boom tip
or when the headache ball contacts the hook block.
7. A critical lift plan is required for all of the following EXCEPT....ANSWER....a routine lift
within 80% of the chart's capacity.
8. The primary reason for using outriggers or crawlers is to....ANSWER....increase the stability
of the crane by widening its base.
9. The recommended hand signal for "stop" is....ANSWER....arm extended, palm down, held
motionless.
,10. A crane is considered to be operating in its least stable configuration when the load
is....ANSWER....at the maximum radius with the boom at its highest angle.
11. The device used to measure the angle of the crane's boom is called a(n)....ANSWER....boom
angle indicator.
12. The minimum safe distance a crane must maintain from an energized power line of 50kV to
200kV, as per OSHA, is....ANSWER....20 feet.
13. The term "boom hoist" refers to the system that....ANSWER....raises and lowers the boom.
14. The primary safety device designed to prevent two-blocking is the....ANSWER....anti-two-
block system (ATB).
15. A load that is irregularly shaped and whose weight is difficult to estimate is considered
a(n)....ANSWER....non-standard load.
16. Before traveling with a load, the operator must ensure the load is....ANSWER....secured and
carried as low as possible.
17. The load chart is based on a crane that is....ANSWER....level and on a firm, stable surface.
18. The primary purpose of a boom stop is to....ANSWER....prevent the boom from being raised
beyond its highest safe angle.
19. The term "side loading" refers to....ANSWER....a force applied to the side of the boom,
which it is not designed to withstand.
20. The device that measures the horizontal distance from the center of rotation to the center of
the hook is the....ANSWER....radius indicator.
21. A sudden loss of engine power on a crane is most likely an indication of....ANSWER....the
automatic shut-down system activating.
, 22. The "gross capacity" of a crane listed on a load chart is the capacity....ANSWER....before
deductions for the weight of hook, slings, and other rigging.
23. The primary reason for a pre-operational inspection is to....ANSWER....identify any potential
defects or hazards before using the crane.
24. The function of the load hoist brake is to....ANSWER....hold the load automatically when the
control lever is returned to the neutral position.
25. When a crane's load block is not centered over the load, it can cause....ANSWER....swinging
of the load and side loading on the boom.
26. The "working range" diagram on a load chart shows....ANSWER....the areas where the crane
can operate without interference from its own structure.
27. A qualified rigger is responsible for....ANSWER....selecting the proper rigging and ensuring
the load is secure.
28. The term "deductible weight" in rigging refers to....ANSWER....the weight of slings, blocks,
and other rigging hardware that must be subtracted from the crane's gross capacity.
29. The primary danger of operating a crane in high winds is....ANSWER....reduced stability and
loss of load control.
30. The load moment indicator (LMI) system provides the operator with a real-time reading
of....ANSWER....the percentage of rated capacity being used.
31. A "tagline" is used to....ANSWER....control the rotation and swing of a lifted load.
32. The purpose of a swing brake is to....ANSWER....hold the crane's upperworks in a stationary
position.
