Accepted Answer

The crane must be taken out of service immediately until the anti-two-block device is repaired

Question 3

What is the purpose of checking hydraulic hose and fitting condition during a crane pre-shift inspection?

Accepted Answer

To identify leaks, chafing, abrasion, or damage that could result in sudden hydraulic failure during operation

Answer

To estimate how many hours until the next scheduled oil change is needed

Question 5

What should an operator do if a crane's rated capacity placard (load chart) is missing or illegible?

Accepted Answer

Remove the crane from service until the original manufacturer-issued load chart is obtained and installed

Answer

Use the rated capacity of a similar crane model as a reference until the placard is replaced

Answer

Estimate capacities using industry-standard tables and document the estimates in the inspection log

Answer

Operate at 50% of the estimated capacity until the placard is replaced within 30 days

Question 6

During pre-operation inspection, an operator notices that one outrigger beam extension pin is bent. What is the appropriate response?

Accepted Answer

Remove the crane from service; a bent outrigger pin is an immediate removal-from-service deficiency

Continue operations if the bent pin still engages the locking hole

Answer

Use the outrigger with the bent pin only for light lifts under 25% of rated capacity

Answer

Monitor the pin during operations and replace it at the end of the shift
