HEO Tower Crane NC III study plan

List every pre-operation inspection item for a tower crane (structure, wire rope, hook block, limit switches, brakes, anemometer, earthing) from memory, then verify against a manufacturer manual and mark gaps

Demonstrate and narrate a full daily inspection walk-around in under 15 minutes, calling out each check and its reject criteria

Identify and correctly name 10 rigging components (sling types, shackles, hooks, master links, turnbuckles) and state their inspection rejection points

Summarize the OSH requirements that govern crane operation on site, including PPE, permit-to-work, and exclusion zone rules, in a one-page note

Compute tension in each leg of a two-leg and four-leg sling at 30, 45, and 60 degrees from horizontal, and explain why the angle factor changes capacity

Select rigging for three given loads (symmetrical, off-centre, and sharp-edged) and justify sling type, protection, and number of legs

Describe how to verify the load's weight and centre of gravity before lift, including using markings, shipping documents, and trial lift

State the hand and radio signals used for hoist, lower, slew, trolley, stop, and emergency stop, and practise them until recall is automatic

Explain the sequence of a safe lift from pre-lift briefing to load landing, including trial lift, tag lines, and slew/trolley coordination

Identify the causes and prevention of load swing, and describe how to control a swinging load without shock loading the crane

Run a mock pre-lift briefing covering roles of operator, rigger, signalman, and banksman, and record who confirms what

Practise radio communication using standard phrases (clear, stand by, hoist slow, stop) and eliminate ambiguous words from your script

Read a tower crane load chart and extract rated capacity for five combinations of radius, jib configuration, and hoist line (single vs double reeve)

Calculate net capacity by deducting hook block, slings, and any jib attachments from rated capacity, and flag lifts where net capacity is exceeded

Explain the effect of wind, out-of-service condition, and travel/erection states on chart values, and state the wind speed at which lifting must stop per the manual

Draft a simple lifting plan for a load near 80% of chart capacity, including radius, weight, rigging, ground bearing, and exclusion zone

Describe the sequence of tower crane erection: foundation and base checks, mast section installation, climbing, slew unit, jib and counter-jib assembly, and counterweight placement

List the roles and responsibilities of the erection supervisor, riggers, and operator during erection and dismantling, and state who authorizes each step

Identify ground bearing and foundation requirements, including the need for a documented bearing capacity check and proper drainage

Explain the tie-in/anchor procedure and the checks performed before, during, and after climbing

Recalculate capacity for a crane after a configuration change (jib length, reeving, or counterweight) and explain why the chart must be re-read

Produce a lifting plan for a tandem or critical lift, including load share calculation and communication protocol

Explain the purpose and content of the crane's documentation pack: load chart, manual, inspection records, and operator certification

Identify common causes of tower crane collapse or overload incidents and the control that prevents each

Summarize the regulatory duties for crane operation, inspection intervals, and record keeping, and list the documents an operator must be able to produce on request

Describe the daily and periodic maintenance tasks within operator scope (lubrication points, rope inspection, brake check, limit switch test) and what must be escalated to a technician

Explain the out-of-service and shutdown procedure, including parking the crane, isolating power, and securing the jib in wind

Outline emergency response for power failure, brake failure, fire, and a load left suspended

Complete a full timed mock assessment covering inspection, rigging, signal recall, and two capacity calculations, and score it against the pass criteria

Re-study your three weakest areas identified by the mock and write a short correction note for each

Deliver a complete, verbalized lifting operation from inspection through landing, as if examined, and self-assess against a rubric

Confirm exam-day logistics, permitted materials, and identification requirements
