Crane Operator Exam Prep NCCCO

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.
