NCCCO Mobile Crane

The written exam is computer-based and multiple choice, testing inspection, setup, operation, load charts, signals, and safety knowledge. The practical exam is separate and hands-on: you perform a pre-shift inspection, set up the crane, and complete load-handling tasks while a NCCCO practical examiner scores you against a checklist. You must pass both to be certified.

You take the written exam matching the crane type and configuration you actually operate. Fixed cab (carrydeck-style) telescopic boom, swing cab telescopic boom, and lattice boom are separate exams. Many operators hold more than one designation. Match your exam to the equipment your employer will document for you, not to whichever test seems easier.

Those figures are set and periodically revised by NCCCO, so this page does not quote them. The current question count, time limit, fee, and passing score are published in the official candidate handbook and on NCCCO's website. Check there before you schedule so you are planning around accurate numbers.

Most candidates find the load chart portion hardest, because it rewards precision rather than general familiarity. The operation and inspection material is usually manageable for someone with real seat time. Candidates who have only read about cranes, without practicing capacity problems on an actual chart for their configuration, tend to struggle most.

Estimating radius instead of reading it from the chart, forgetting to deduct stowed jib, auxiliary head, or other attachments from gross capacity, ignoring footnotes and range limitations, confusing gross and net loads, and missing out-of-level or ground-bearing conditions. On the practical side, sloppy pre-shift inspections and rushed hand signals cost points.

Start with load charts: radius, boom angle, boom length, configuration, deductions, and notes. Then move to operation, since much of it depends on chart literacy. Cover setup and inspection next, then hand signals and general safety. Finish by drilling full practice sets and rehearsing the practical sequence on real equipment.

The written and practical results are tracked separately, and NCCCO sets the retake waiting periods and fees for each. Rather than guessing at the rules, check the current candidate handbook on NCCCO's site. In practice, most people who fail one section retake only that section after focused review.

Certification runs on a five-year cycle. Renewal typically involves recertification requirements rather than simply paying a fee, so plan ahead - do not let a lapsed card cost you a job. NCCCO publishes the current recertification options, deadlines, and any required exams or practical re-tests on its website.

NCCCO sets eligibility requirements, which have included minimum age, compliance with a substance-abuse program, and documentation of training or experience depending on the designation. These requirements change, so verify them in the current candidate handbook before you register. Employers can often help document your operating hours.

Practice the exact sequence until it is routine: pre-shift inspection with verbal callouts, setup including leveling and outrigger or tire checks, then smooth controlled load movement with correct hand signals. Work on a crane of the same configuration you are testing on, and have someone watch for the inspection and signaling details you will be graded on.
