3. Who is ultimately responsible for the safety of the crane operation on a worksite?
A. The Signal Person
B. The Crane Operator
C. The Oilerman
D. The Site Supervisor
4. A Qualified Rigger is required when:
A. The load weight is over 2,000 lbs.
B. The load is a pre-engineered building component.
C. The load cannot be directly hooked by the operator and requires a sling.
D. The lift is a critical lift.
5. According to OSHA, a formal documented inspection of the crane (by a competent person)
must be performed:
A. Daily
B. Monthly
,C. Annually
D. Weekly
6. The purpose of a pre-lift meeting is to:
A. Discuss the operator's pay.
B. Review the lift plan, roles, and potential hazards.
C. Inspect the crane's engine.
D. Plan the route for moving the crane.
7. A "Critical Lift" is defined as any lift that:
A. Takes longer than 10 minutes.
B. Involves multiple cranes or is over 75% of the crane's capacity.
C. Is performed at night.
D. Involves a load that is longer than 50 feet.
8. The minimum distance a crane's boom or load should maintain from an energized power
line of 50kV to 200kV is:
A. 10 feet
B. 15 feet
C. 20 feet
D. 50 feet
9. A "Competent Person" is defined as someone who:
A. Has a college degree in engineering.
B. Is capable of identifying existing and predictable hazards and has authority to correct them.
C. Has been operating a crane for more than 5 years.
D. Is the site foreman.
10. The primary purpose of a boom angle indicator is to:
A. Measure the wind speed.
B. Prevent the boom from being raised too high.
C. Provide the operator with the boom's angle relative to horizontal.
D. Calculate the load radius automatically.
Section 2: Crane Operations and Principles
11. The rated capacity of a crane is based on its ability to lift a load:
A. With the boom fully retracted.
B. On a perfectly level, firm surface with outriggers fully extended.
, C. On rubber tires without outriggers.
D. At its maximum boom length and radius.
12. What is the primary cause of crane tip-overs?
A. Mechanical failure of the wire rope.
B. Operator error and instability from exceeding the crane's capacity chart.
C. Sudden gusts of wind.
D. Failure of the outrigger beams.
13. When making a lift, the operator should always hoist the load a few inches and hold it to
check:
A. The fuel level.
B. The brake system and crane stability.
C. The radio connection with the signal person.
D. The travel path for obstructions.
14. The center of gravity of a load is critical because:
A. It determines the color of the slings to use.
B. It must be known to maintain control and balance during the lift.
C. It is only important for loads over 10,000 lbs.
D. It affects the travel speed of the crane.
15. Dynamic loading refers to:
A. The weight of the crane itself.
B. The static weight of the load on the hook.
C. The additional forces imposed on the crane from sudden movements, stopping, or starting.
D. The load chart calculations.
16. Side-loading the boom is dangerous because it:
A. Can cause the load to spin.
B. Can induce severe stress on the boom, potentially causing structural failure.
C. Is an inefficient way to position a load.
D. Is only a problem for lattice booms.
17. The primary safety device that prevents the crane from hoisting a load that is too heavy is
the:
A. Boom Angle Indicator
B. Anti-Two-Block System
