HEO Tower Crane NC III study guide
HEO Tower Crane NC III · Work through your exam, one topic at a time.
The HEO Tower Crane NC III credential is a Philippine TVET certification under the Heavy Equipment Operation (HEO) sector, designed for individuals who operate tower cranes in construction, infrastructure, and industrial settings. It is intended for aspiring and practicing operators who need to demonstrate competence in pre-operation inspection, rigging and site preparation, crane setup and dismantling support, safe lifting operations, load control, signal communication, load chart interpretation, lifting plan development, and basic maintenance and troubleshooting. The HEO Tower Crane NC III study guide has 7 sections and about 2,337 words.
01Pre-operation inspection, rigging, and site preparation
This domain tests what you verify before the first lift of a shift: the condition of the machine, the rigging gear, and the ground and airspace around the crane. Examiners want an inspection sequence, not a random walk around the base.
315 words, about 2 min02Tower crane setup, erection, and dismantling support
The NC III operator supports the erection team; the erection supervisor and competent rigger direct the sequence. Your answers must show what you verify and what you refuse to do.
332 words, about 2 min03Safe lifting operations and load control
This domain tests whether you can take a load from ground to set-down without shock loading, overloading, or losing control. The exam favours sequence and judgement over speed.
358 words, about 2 min04Signals, communication, and team coordination
Every lift is a three-way loop between the operator, the signalman or rigger, and whoever controls the site. The exam tests whether you keep that loop closed and unambiguous.
327 words, about 2 min05Load charts, lifting plans, and capacity calculations
This is the numeracy domain. You must read the manufacturer's chart correctly, deduct everything hanging below the hook, and prove the pick is inside capacity.
326 words, about 2 min06Occupational safety, health, and environmental regulations
The exam checks that you can name the governing framework and apply it on a tower crane site: Republic Act 11058 with its implementing rules DO 198-18, the DOLE Occupational Safety and Health Standards, and the project safety plan. Roles: safety officer, safety committee, trained first-aiders, and the operator's duty to report hazards and refuse unsafe lifts.
309 words, about 2 min07Basic maintenance, troubleshooting, and shutdown procedures
The operator maintains and shuts down the crane; the technician repairs it. The exam penalises answers that blur that line.
