Crane Operator Prep: NCCCO CCO

Pass the written CCO Mobile Crane Operator Core Examination. PrepSure is built for working operators — studying in a truck cab at 6am, on a jobsite during a break, or the night before the test. Large type, high contrast, big touch targets, and a real dark mode. No mascots, no streaks, no confetti. A tool, not a game. THE LOAD-CHART TRAINER No other app has one. Read a real capacity grid where structural and stability limits are legible on the chart itself, not buried a tap deeper. Tap any cell to see which limit governs, explained in plain language. Then build your rigging deductions and watch the net capacity fall — because forgetting a deduction is the single most common way to fail the load-chart questions, and this makes that omission impossible to miss. Range diagram and work-area chart included. 400 QUESTIONS AT THE REAL EXAM WEIGHTS Site (20%), Operations (26%), Technical Knowledge (28%) and Manufacturers' Load Charts (26%) — the same proportions the exam uses, so your practice reflects the real thing. Every question was written from public federal regulation and reviewed by a certified crane operator. EVERY ANSWER EXPLAINED Not just which option is right, but why each wrong one is wrong, with the regulation cited and a link to read the actual text. Missed a question? It comes back, spaced so the ones you keep getting wrong come round more often. SIX WAYS TO STUDY Quick 10 · Timed 20 · Full Mock (90 questions, 90 minutes, scored) · Weakest Subject · Missed Questions · Flagged. KNOW WHEN YOU'RE READY A readiness score weighted the way the exam weights its domains — so being strong in a light domain can't hide being weak in a heavy one. WORKS COMPLETELY OFFLINE Every question, chart and explanation lives on your phone. No signal needed, no account, no sign-up. Nothing you do in this app leaves your device — we collect nothing. TRY IT FREE 45 questions free, sampled across all four domains so you can judge the real mix. Unlock everything with one payment. No subscription. IMPORTANT This app prepares you for the WRITTEN Core examination only. It does not prepare you for the practical (hands-on) exam, and it does not cover the specialty exams you also need to be certified. All cranes and load charts in this app are fictional training models created for teaching. They are never manufacturer data and must never be used to plan a real lift.
