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.
