NCCCO Mobile Crane Operator 3

Question 1

What document must a certified mobile crane operator possess while operating a crane?

Accepted Answer

Their NCCCO certification card for the specific crane type being operated

Answer

Operators must carry their NCCCO certification card specific to the type of crane they're operating (lattice boom, telescopic boom, etc.). Different crane types require separate certifications.

Question 2

Before operating any mobile crane, the operator must verify:

Accepted Answer

That annual inspection is current, the crane is set up per manufacturer specs, and all safety devices are functional

Answer

Operators must verify current inspection status, proper setup (outriggers, counterweight), functional safety devices (LMI, anti-two-block, limit switches), and that conditions match the load chart configuration.

Question 3

What is the mobile crane operator's responsibility regarding ground conditions?

Accepted Answer

The operator must evaluate whether the ground can adequately support the crane and refuse to operate if conditions are inadequate

Answer

Operators share responsibility for evaluating ground conditions. Soft, sloped, or undermined ground can cause outriggers to sink or the crane to tip, regardless of what the load chart shows.

Question 4

When operating near other cranes, what is the minimum safe distance to maintain?

Accepted Answer

Enough distance to prevent booms, loads, or lines from contacting each other, as established in the site lift plan

Answer

Multi-crane sites require coordination to prevent collisions between booms, loads, and wire ropes. The lift plan should establish swing limits, exclusion zones, and communication protocols between operators.

Question 5

What must a mobile crane operator do at the end of each shift?

Accepted Answer

Secure the crane (set brakes, lower boom or secure per procedure, turn off engine), complete inspection notes, and report any issues

Answer

End-of-shift procedures include securing all crane functions, documenting any issues observed during operation, completing the daily inspection log, and communicating concerns to the incoming operator or supervisor.
