NCCER Crane Maintenance, Inspection & Equipment Setup 5

Question 1

What is the purpose of performing a function test at the beginning of each shift?

Accepted Answer

To verify all crane controls, brakes, and safety devices are operating correctly before any load is applied

Answer

Shift function tests verify that all controls, brakes, limit switches, and safety devices respond correctly before the crane is put under load, catching deficiencies when they can be corrected safely.

Question 2

When is a crane hook considered 'twisted' and must be removed from service?

Accepted Answer

When the hook has been twisted more than 10 degrees from the plane of the unbent hook

Answer

Per ASME B30.10, a hook that has been twisted more than 10 degrees from the plane of the unbent hook must be removed from service as this indicates yielding of the steel.

Question 3

What does 'rated capacity' on a crane load chart account for?

Accepted Answer

The maximum load the crane can lift with all specified configuration and radius conditions met, including all safety factors

Answer

Rated capacity represents the maximum allowable lift for a specific configuration, radius, and boom angle and already incorporates the required safety factors established by the manufacturer and standards.

Question 4

During inspection, the crane's travel brake is tested and takes 3 feet to stop the crane on a level surface. What is the correct response?

Accepted Answer

Compare the stopping distance against the manufacturer's specification; adjust or repair if out of specification

Answer

Travel brake stopping distance must be compared against the manufacturer's performance specification for the specific crane model; deviations require adjustment or repair before continued operation.

Question 5

What is the correct storage procedure for a wire rope that has been removed from service but is being retained for future use?

Accepted Answer

Clean, lubricate, coil on a reel with minimum 18-inch diameter, and store under cover off the ground

Answer

Wire rope must be cleaned, lubricated, spooled on a reel of sufficient diameter to prevent kinking, and stored under cover off the ground to prevent corrosion and mechanical damage.
