NCCCO Tower Crane study plan
NCCCO Tower Crane · Give each week a clear focus.
8 weeks · About 7 hours per week
Load Charts and Rigging
Read a manufacturer load chart and locate rated capacity for a given boom length, radius, and jib configuration
Compute net capacity by subtracting rigging weight and applying the correct capacity deduction
Distinguish structural limits from stability limits on a tower crane chart and state which governs at a given radius
Convert radii and loads between feet/inches and meters, and between pounds and kilograms, without arithmetic error
Your checkpoint
Completed 25-item chart-reading worksheet scored at 90% or better, with every missed item annotated with the specific reason for the error
Load Charts and Rigging & Site Preparation and Crane Setup
Calculate sling tension for two-leg, three-leg, and four-leg bridle hitches at 30, 45, and 60 degree horizontal angles
Determine load weight from volume and material density for steel, concrete, and lumber
Select shackles, hooks, slings, and hardware sized to the calculated load and hitch configuration
Identify site conditions that affect crane setup, including soil type, slope, and adjacent structures
Your checkpoint
A written rigging plan for one simulated lift containing the weight calculation, sling tension, hardware list, and a text-described sketch of the hitch
Site Preparation and Crane Setup
Explain how the crane's foundation requirements relate to the reaction loads the foundation must resist
Estimate ground bearing pressure for the crane's support condition and decide whether a mat or pad is required
Determine minimum clearance distances from energized power lines, adjacent structures, and other cranes
Lay out a crane position that satisfies swing radius, tail swing, and erection and dismantling space
Assemble a site-specific setup checklist from the requirements you derived
Your checkpoint
A written site setup plan for a hypothetical congested urban site with a stated crane position and a text-described clearance diagram justified by specific distances
Crane Assembly, Disassembly, and Climbing
Sequence tower crane assembly from base section through mast, turntable, jib, and counterweight, listing every step in order
Identify the function of mast sections, climbing frame, hydraulic unit, turntable, and counterweight
Describe the climbing sequence and list the conditions that must be satisfied before climbing begins
Recognize pre-assembly inspection points for pins, bolts, and structural members
Your checkpoint
A written assembly-and-climbing procedure with all steps in correct order, self-scored against a checklist rubric with no omissions
Crane Assembly, Disassembly, and Climbing & Lifting Operations
Describe the roles and duties of the assembly director, signal person, and operator during assembly and dismantling
State the wind-speed limits that apply to erection, climbing, and lifting operations
Identify the post-assembly inspection and load-testing requirements that must be met before the crane goes into service
Plan a lift end to end by determining rigging, radius, capacity utilization, and travel path
Your checkpoint
A complete lift plan for one critical or near-capacity lift containing every required field and a calculated capacity utilization percentage
Lifting Operations
Interpret standard hand signals and state the correct radio and voice communication protocol for a lift
Explain how to read the load moment indicator and describe the correct action as the crane approaches a limit
Plan a blind lift and a lift over an occupied area, stating the controls each requires
Determine when taglines are required and identify prohibited practices such as side loading and dragging loads
Your checkpoint
A tabletop walkthrough of five lift scenarios recording the decision made at each triggering condition and the reason for it
Safety, Inspection, and Maintenance
Distinguish daily, monthly, annual, and post-assembly inspection intervals and list what each covers
List the items verified during a pre-shift inspection of wire rope, hooks, brakes, and limit devices
Describe lockout/tagout and the procedure for removing a deficient crane from service
State wire rope removal criteria and the recordkeeping required for maintenance
Identify fall protection and personnel lifting requirements
Your checkpoint
A completed daily inspection checklist plus a written list of ten simulated deficiencies, each paired with the correct corrective action
Site Preparation and Crane Setup & Crane Assembly, Disassembly, and Climbing & Load Charts and Rigging & Lifting Operations & Safety, Inspection, and Maintenance
Complete three timed 60-question practice exams spanning all five domains
Categorize every missed item by domain and by error type (knowledge gap, misread, calculation)
Re-derive the fifteen most common calculations from memory without notes
Condense limits, clearances, and signal definitions onto a single reference page
Your checkpoint
Three practice exams scored at 85% or higher with a written error-analysis log identifying each weak sub-topic
Milestones
Week 2: Score 80% or better on a self-written 20-question quiz on load charts and rigging, with all calculation items shown as worked steps
Week 4: Score 80% or better on a 30-question self-written quiz covering domains 1, 2, and 3
Week 6: Complete the five-scenario tabletop walkthrough with a defensible stated reason for every decision, and score 80% or better on a 25-question lifting-operations quiz
Week 8: Average 85% or higher across three timed 60-question practice exams with no single domain below 75%
