NCCCO Mobile Crane study plan

Define gross capacity, net capacity, and maximum allowable load, and compute net capacity by deducting all lifting-gear weight from the chart value.

Locate the correct boom length and radius intersection on a manufacturer load chart for at least five different configurations.

Distinguish structural limits from stability limits and state which governs at short radius versus long radius.

Calculate working radius from measured boom angle and boom length using the cosine relationship, and verify against a tape measurement.

Apply correct deductions (headache ball, load block, slings, jib, auxiliary sheave) to determine net capacity across 10 chart scenarios.

Determine when parts of line and rated line pull govern capacity instead of the boom table, and compute the effective limit.

Identify the chart notes and warnings that invalidate a capacity value, such as unlevel crane, outriggers not fully extended, side loading, and travel.

Sequence the pre-lift checks an operator completes before the first pick of a shift.

Set up and level a crane on outriggers, verifying float extension, pad contact, and that all tires are clear of the ground where required.

Calculate ground bearing pressure for a given outrigger load and select a mat size that keeps pressure under the soil capacity.

Manage radius by measuring at the load hook and accounting for boom deflection and load swing during the lift.

Sequence a lift plan covering hazard identification, rigging verification, signalperson briefing, and trial lift.

Identify the conditions that require a critical lift plan and list the contents such a plan must contain.

Apply minimum approach distances to power lines for each voltage class and state the required actions following contact.

Describe safe practice for pick-and-carry, travel with a suspended load, and multi-crane lifts, including when each is prohibited.

Explain how wind, side loading, rapid swing, and boom flex affect stability and capacity.

Verify ground conditions, blocking, and levelness before any configuration change or assembly task begins.

Describe the assembly and disassembly sequence for boom sections, and state the duties of the assembly director and the pin and clip verification checks.

Confirm counterweight and jib installation checks and determine when a stowed or swing-away jib changes the load chart in use.

Position a crane on a sample site diagram, calculating clearances and confirming the planned area of operation.

Perform a documented pre-shift inspection covering fluids, tires, wire rope, hook and latch, limit switches, alarms, and outriggers.

Inspect wire rope samples and identify removal criteria including broken wires, kinks, crush damage, corrosion, and diameter reduction.

Separate daily, periodic, and annual inspection requirements and state the record-keeping obligation for each.

Confirm the load chart, operator manual, and capacity decals are present and match the crane's current configuration.

List operator, signalperson, and rigger responsibilities under the applicable consensus standard and OSHA crane rules.

Demonstrate the 20 standard hand signals and the corresponding voice or radio commands, without reference.

Explain signalperson qualification requirements, when a signalperson is mandatory, and the operator's stop-work authority.

State the correct response when a signal is unclear, duplicated, or the load approaches a prohibited zone.

Complete two full-length timed practice exams and break down the score by domain to rank remaining weak areas.

Re-drill every missed load chart item until accuracy on that item type reaches 95%.

Reproduce from memory a one-page reference sheet of capacity formulas, deduction rules, and approach distances.

Verify readiness on the two lowest-scoring domains with a focused 30-question set on each.
