Try these sample questions to review concepts for the HEO Tower Crane NC III exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1What is the primary purpose of performing a visual check of the tower crane before productive operation per CON834310?

A.To identify worn, damaged, loose, or missing parts while the power supply is switched off

B.To test all safety devices at maximum rated load immediately

C.To replace major mechanical components without a checklist

D.To operate the crane at full speed to warm up motors

Explanation: CON834310 requires a visual/walk-around check using the equipment checklist while power is switched off, inspecting OS parts, hook block, wire rope, controls, and base foundation before energizing.

2When should the tower crane operation (function) check be performed according to CON834310?

A.While the power supply is switched on, following the manufacturer's recommendations and equipment checklist

B.Only after the crane has lifted its maximum rated load for the day

C.With all safety devices bypassed to verify motor response

D.After post-operation shutdown when brakes are fully engaged

Explanation: Element 3 of CON834310 specifies operation checks with power on, verifying mechanical components, gauges, controls, and safety devices per manufacturer specifications.

3Which document must be accomplished and submitted after productive operation per CON834310?

A.Daily Equipment Time Report (DETR) according to company rules and regulations

B.Bill of lading for the last load lifted

C.Load chart certification from the manufacturer

D.TESDA National Certificate renewal form

Explanation: Criterion 4.5 of CON834310 requires the operator to accomplish and submit the Daily Equipment Time Report (DETR) as part of post-operation procedures.

4After productive operation, in what position should the tower crane controls be set per CON834310?

A.Neutral position in accordance with the manufacturer's manual

B.Full hoist up position to keep the hook clear

C.Maximum swing speed setting

D.Travel forward engaged to prevent wind movement

Explanation: CON834310 element 4 requires controls set to neutral, safety locks and brakes engaged, and the crane secured per the manufacturer's manual.

5Which PPE items are listed in the CON834310 range of variables for tower crane operation?

A.Hard hat, goggles, gloves, safety shoes, reflectorized vest, and full body harness with double lanyard and rebar hook

B.Cotton coveralls only without head protection

C.Leather apron and welding helmet exclusively

D.Open-toe safety sandals with reflective tape

Explanation: The TR range of variables lists hard hat, goggles, gloves, safety shoes, reflectorized vest, and full body harness with double lanyard and rebar hook.

6During pre-operation visual inspection with power off, which hook block assembly items must be checked per CON834310?

A.Sheaves, hook, and safety latch

B.Slewing motor windings and gearbox only

C.Counterweight bolts on the jib tip only

D.Anemometer calibration certificate

Explanation: Inspection variables include hook block assembly items: sheaves, hook, and latch during power-off visual inspection.

7Which tower crane component supports rotation of the upper works about the vertical mast?

A.Slewing unit

B.Counter jib only

C.Trolley carriage

D.Tie bar exclusively

Explanation: CON834310 lists slewing unit among tower crane components; it enables rotation (swing) about the mast axis.

8An abnormal condition found during component visual check should be:

A.Noted on the checklist and reported to authorized personnel

B.Ignored if the crane still operates

C.Repaired immediately without reporting regardless of severity

D.Documented only after one week of operation

Explanation: CON834310 criterion 2.2 requires abnormal conditions noted on the checklist and reported to authorized personnel.

9Which safety device listed in CON834310 limits crane motion in the hoisting direction?

A.Hoisting limit switch

B.Anemometer

C.Hour meter

D.Boom angle indicator only

Explanation: Limit switches include hoisting, slewing, traveling, trolleying, and derricking. The hoisting limit switch prevents over-hoisting.

10What is the Load Moment Indicator (LMI) primary function on a tower crane?

A.Monitor load and radius to warn when approaching rated capacity

B.Measure engine RPM only

C.Control trolley travel speed automatically at all times

D.Replace the need for a signal person on every lift

Explanation: LMI is a safety device that monitors loading relative to capacity and alerts the operator when limits are approached.
