CRANE OPERATOR EXAM PREP: PASS YOUR NCCCO CCO CERTIFICATION The NCCCO written exam requires a 70 percent score. Load charts account for 26 percent of the Core exam. Candidates who fail are almost always weak on load chart math: net capacity calculation, deductions, percentage of capacity, and outrigger vs on-rubber limits. This app is built around exactly that weakness. LOAD CHART CALCULATOR Enter boom length and operating radius. The calculator returns gross capacity, then walks through net capacity step by step: Gross capacity (from load chart by boom length and radius) minus hook block weight minus rigging weight (slings, shackles, hardware) minus jib or auxiliary line weight if applicable equals net available capacity Enter your load weight. Get an instant verdict: GREEN: Safe to lift. YELLOW: Caution — within 90 to 100 percent of capacity. RED: Over capacity — do not lift. Uses generic training data only. Always use the manufacturer's load chart for actual lift planning. 380+ PRACTICE QUESTIONS Core Exam — Required for all CCO operators: Load chart interpretation: boom length and radius intersection, gross vs net capacity, outrigger vs on-rubber capacity. Net capacity calculations: deducting hook block, rigging, and auxiliary equipment. Percentage of capacity: calculating how much of rated capacity a lift represents. Crane setup: outrigger placement, ground bearing pressure, leveling requirements. Site knowledge: overhead power line clearances, grade requirements, ground conditions. OSHA 1926 Subpart CC: certification requirements, pre-shift inspection, critical lifts. ASME B30.5: operating limitations, inspection requirements. Specialty Exams: Lattice Boom Crawler (LBC): boom sections, travel with load, track bearing pressure. Lattice Boom Truck (LBT): outrigger requirements, axle loads, over-the-front vs over-the-side. Telescopic Boom Fixed Cab (TLL): extension and retraction, boom angle and radius. Telescopic Boom Swing Cab (TSS): swing cab operation, telescope sequencing. HAND SIGNAL REFERENCE All standard ASME B30.5 and OSHA hand signals: Hoist, Lower, Stop, Emergency Stop, Use Main Hoist, Use Whipline, Raise Boom, Lower Boom, Swing, Travel, Dog Everything, Extend and Retract Boom. PRE-OPERATION CHECKLIST OSHA 1926.1412 compliant daily inspection: control mechanisms, safety devices (anti-two-block, load moment indicator), wire rope condition, hooks, fluid levels, ground conditions. RIGGING REFERENCE Sling angle capacity loss at 90, 60, 45, and 30 degrees. Wire rope ratings. Shackle loading. Hitch types: vertical, choker, basket. FREE: 5 questions per day, load chart basic verdict, 5 hand signals. No account required. MONTHLY ($9.99/month): Full 380+ question bank, complete Load Chart Calculator, Hand Signal Reference, Pre-Op Checklist, Rigging Reference, progress by exam section, 3-day free trial. ANNUAL ($24.99/year): Everything in Monthly. Save over 74 percent. Best value. LIFETIME ($49.99): One payment. Permanent access.

REAL EXAM FORMAT Skip questions, flag them for review, go back, and change your answers — just like test day. Nothing is revealed until you submit. Core is 90 questions in 90 minutes, each specialty is 26 in 60, matching the published CCO structure. REVIEW EVERY ANSWER After you submit, walk back through the whole exam: what you picked, the correct answer, why it's correct, and the OSHA or ASME standard behind it. Your flagged questions are marked so you can find them fast. FREE SAMPLE EXAM Take a 10-question scored mock exam free, once a day. Same engine as the full test, including the answer review, so you can see exactly where you stand before deciding on Pro. 80 NEW SPECIALTY QUESTIONS Telescopic boom and lattice boom pools covering outrigger position charts, on-rubber capacity, pick-and-carry, LMI, boom hoist and gantry, backward stability, assembly and disassembly, and quadrant charts. The crane type you pick in Settings decides which pool your specialty exam draws from. 580 questions total. BETTER STANDARD REFERENCES 216 questions now cite the standard they come from — ASME B30.5, B30.9, B30.26, OSHA 1926.1402-1404, 1926.1412, 1926.1419-1422 — instead of a generic reference. CORRECTED FIELD MATH The outrigger pad calculator now sizes pads from worst-case corner loading instead of an even four-way split, which understated ground bearing pressure during a lift. Wind derating follows manufacturer-style percentage bands. Choker hitch capacity no longer takes a sling angle reduction that doesn't apply to a single-leg pull. One power line clearance card was corrected: with unknown voltage, maintain 20 feet, or 50 feet above 350 kV. 55 MORE FLASHCARDS Every one of the 16 study guide topics now has spaced-repetition cards, including outriggers, ground bearing pressure, hitches, and OSHA Subpart CC. ALSO IN THIS UPDATE Bookmarked questions now have a home in Settings. Daily study reminders keep your streak alive. VoiceOver labels on hand signals, calculator results, and study cards. Layout scales properly at large text sizes. Faster launch. ### 2.3 — 2026-06-09 What's New • Reset Progress — start over anytime.
