Practice questions based on the published NCCCO mobile crane operator exam outlines and the consensus safety practices the trade runs on. CCO and NCCCO are marks of the National Commission for the Certification of Crane Operators; this site is not affiliated with or endorsed by NCCCO. Capacity always comes from the load chart for the machine and configuration in front of you, and wind, ground-bearing and permit limits are set by the manufacturer's manual and the authority having jurisdiction — never from a practice question.
