Tower Crane Operator

Practical Exam Outline

The following is an outline of the practical testing procedure, as provided to candidates at the time of testing.

CANDIDATE INFORMATION AND INSTRUCTIONS

The following sections describe the specific tasks that you will be performing when taking the Practical Examination. It is important that you understand these instructions. If there is anything you do not understand, please request clarification from the Examiner.

TASKS

The Three Tasks are:

VIEW VIDEO EXAMPLE:

If you are not able to view the video, click here to update your computer with the latest version of Java.

There is also a Pre-Test Briefing, a Pre-Test Familiarization Period, and a Pre-Task Familiarization Period (prior to the Load Circle task) with a load. You will be required to complete all phases of the test in sequence.

The Test Site Coordinator is responsible for setting the testing schedule. If you are familiar with the operation of the test crane, you may elect to test first to allow other candidates time to review the operator’s manuals and load charts. Otherwise, selection shall be by random drawing or by assignment of the Test Site Coordinator.

During the Practical Examination, you are under the direction of the Examiner and must follow the Examiner’s directions at all times.

Once you have completed all of the tests you are taking, you must leave the testing area. Only personnel involved in the administration of the test are allowed in the test area.

TIME LIMITS

An optimum time limit has been set for all tasks and is stated as part of the task descriptions. If the task is completed within this time period, you receive no time penalty.

Once you exceed this time limit, you will lose points on a gradual basis. If you take one and a half times as long as the optimum time, you will have lost all the points allotted to that particular task. At two times the optimum time the Examiner may end the task and move on to the next task.

PRE-TEST BRIEFING

While you are waiting to take your test, you will have sufficient time to read this description of the tasks to be performed and review the operator’s manual and load chart for the crane you will operate. In addition, you will be informed of the make and model of the crane, the load hook height, jib length, and the weight of the test load. You will also watch a short video showing all the tasks you will be required to perform during the examination.

Note that:

  • The crane's LMI system (if the crane is so equipped) has been correctly programmed and will not interfere with the proper operation of the crane.
  • The crane has been set up and leveled.
  • None of the target points have been placed at a radius that exceeds the crane's rated capacity.

CIRCUMVENTING THE COURSE

Circumventing the course on the NCCCO Tower Crane Operator Practical Exam is defined as when the load:

  •  Leaves the Zigzag Corridor and passes more than one pole without touching them before re-entering the corridor
  • Leapfrogs from one leg of the Zigzag Corridor to another with the chain off the ground
  • Passes more than four poles consecutively with the chain off the ground, inside or outside of the corridor

All points for a task are lost if a circumvention occurs. The Examiner has the authority to stop the task at any time if he/she feels that the candidate is attempting to circumvent any task.

UNSAFE ACT

If, at any time during the Pre-Test Familiarization Period or during the test, you commit an unsafe act, you will be disqualified from continuing with the test. Unsafe acts include but are not limited to the following:

  • Dropping the load hook or Test Weight (on ground)
  • Uncontrolled or reckless operation
  • Failure to respond to a stop signal
  • Contacting an obstruction with the crane or Test Weight
  • Load touching any part of the candidate’s body
  • Touching the crane with load hook or load
  • Any action that in the judgment of the Examiner could endanger personnel or equipment at the Test Site.

The Examiner has the authority to stop the test at any time for reasons of safety. Please ask the Examiner if you have questions.

If you are disqualified due to an unsafe act, your case will be reviewed by IAI and NCCCO, and you will be notified as to your eligibility for rescheduling your Practical Exam.

CANDIDATE ID AND SIGNATURE

Prior to beginning the examination, the Examiner will ask you for a photo identification, such as a driver’s license.

The Examiner will ask if you have read the Candidate Information and Instructions and will answer any questions you may have. He/she will review with you the weather conditions and ask you to sign indicating that you understand the instructions for the test and that you agree with the Examiner’s assessment of the weather conditions.

WEATHER CONDITIONS/EQUIPMENT PROBLEMS

The Examiner will use an anemometer to check the wind speed and record weather conditions on your score sheet.

The Examiner has the responsibility to determine if weather conditions/equipment problems are such that a test needs to be suspended. If the test is interrupted due to equipment problems, the procedure for restarting will be as follows:

  • You will resume the test at the beginning of the task you were performing at the time of the interruption, except for Task 3, when you will go back to the beginning of either Task 3a or 3b, as appropriate.
  • You will be entitled to a Pre-Test or Pre-Task Familiarization Period before resuming the test.
  • If you resume the test on a different machine, you will have the option of starting the entire test over from the beginning.
  • If the testing is delayed to a different day, the test must be restarted from the beginning.

PRE-TEST FAMILIARIZATION PERIOD

  • You will be allowed 15 minutes to familiarize yourself with the crane and to examine anything on the crane that you feel is necessary to operate it comfortably.
  • You will be allowed to get the feel of the controls and run the crane through its functions. The jib length has been preset. The brakes and other devices have been set according to the crane manufacturer’s recommendations.
  • You may not interfere with the test course, lift the Test Weight, or shadow the Zigzag Corridor and Load Circle.
  • You must finish the Pre-test Familiarization Period with the load hook under control in the Start Circle within the 15-minute period.
  • The Examiner will notify you when there are ten, five, and one minute(s) remaining.
  • If you are ready in less than 15 minutes, you may indicate this to the Examiner.
  • If, at the end of the Pre-Test Familiarization Period, you feel you are not ready to take the examination, you should notify the Examiner. You will have, in effect, disqualified yourself from taking the examination at this time, and you will be required to sign to that effect on the Candidate Score Sheet.

TASK 1: PLACE LOAD HOOK AND CHAIN IN STOP CIRCLE

Optimum Time — 1 1/2 minutes

  • At the Examiner's indication to start at which point time will begin,raise the load hook and chain at least 10 ft. off the ground to clear all obstacles and personnel.
  • Bring it from its starting position in the Start Circle to the Stop Circle.
  • Once the load hook and chain reach the Stop Circle place it there such that the chain suspended from the hook makes contact with the ground inside the circle and remains there.
  • Once the chain makes contact with the ground inside the circle, you are not permitted to lift the chain off the ground.
  • The Examiner will give you a stop signal once the load hook and chain are under control.
  • Points will be deducted for the following:
    • Dragging or contact of chain outside of the circle.
    • Load hook touching ground either inside or outside of the circle.
    • Load hook or chain contacting any part of the course (e.g., poles).
    • Lifting the chain off the ground after it has made contact with the ground inside the circle.

PRE-TASK FAMILIARIZATION PERIOD (WITH TEST WEIGHT)

This part of the Examination is not scored.

  • At the Examiner's indication, bring the load hook over the Test Weight located in the test Weight Circle.
  • The load will be attached to the crane's load hook by the Examiner or Proctor.
  • You are allowed to bring the Test weight to the designated are where you can get the feel of the load, test the break, etc. before beginning the Load Circle task.
  • You may not swing the load outside of the designated area or shadow the zigzag course.
  • You will be allowed a maximum of five (5) minutes for this Pre-Task Familiarization, by the end of which period, you must have placed the Test weight on the ground in the Test Weight Circle with the rigging taut.
  • The Examiner will notify you when there is one (1) minute remaining.

TASK 2: PLACE TEST WEIGHT IN LOAD CIRCLE

Optimum Time --- Four  minutes (4:00)

  • At the Examiner’s indication to start at which point timing will begin, bring the Test Weight from the Start Circle to the Load Circle.
  • Swing, trolley or hoist as necessary to place the est Weight on the ground completely within the Load Circle.
  • The Examiner will then five the hoist and swing signal and this will indicate that you should then hoist and swing to place the Test Weight on the ground in the Start Circle.
  • Do not let any part of the Test Weight make contact with the PVC barriers that surround the Load and Star Circles.
  • Timing will end when you have placed the Test Weight on the ground in the Start circle.  Task is not complete until the load is placed completely within the outside perimeter of the circle ad the Examiner has given you a stop signal.  If the Examiner has not given you a stop signal, this will indicate that the weight is not within the circle and the task continues to be timed.
  • Points will be deducted for the following:
    • Knocking ball off pole.
    • Knocking pole over.
    • Exceeding the optimum time.
    • Hitting any part of the course.

TASK 3: NEGOTIATE ZIGZAG CORRIDOR WITH LOAD:

Optimum Time - Three minutes each direction (3:00).

This task is divided into two tasks 3A and 3B.  3A requires you to go through the corridor in a forward direction.  3B requires you to go though the corridor in a reverse direction.

  • At the Examiner’s direction to start at which point timing will begin, lift the Test Weight into the and swing, trolley or hoist up or down as you judge necessary to guide the load through the Zigzag corridor without touching the ground with the Test Weight, or raising the Test Weight so high that the chains leave the ground, or knocking over any part of the PVC barrier.  Points will be deducted for the following:
    • Knocking ball off pole
    • Moving pole base off line
    • Knocking pole over
    • Chain leaving ground
    • Load touching ground
    • Circumventing the task
    • Exceeding the optimum time
  • Timing stops when you have placed the Test Weight on the ground in the Stop Circle and the Examiner has given you a stop signal. The task is not complete until the load is placed completely within the outside perimeter of the circle and the Examiner has given you a stop signal. If the Examiner does not give you a stop signal, this indicates the weight is not within the circle, and the task continues to be timed.
  • The Proctor will then detach the Test Weight from the load hook.
  • At the Examiner’s direction, swing the load hook to the Start Circle and allow the Examiner to attach the chain in readiness for the next candidate. Remain in the cab or at the operator’s station until the Examiner gives you a clear indication that you may leave. Set the swing brake and lock before leaving.
