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 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 Four Tasks are:
There is also a Pre-Test
Briefing, a Pre-Test Familiarization Period, and a Pre-Task
Familiarization Period (prior to the zigzag task) with a load.
You will be required to complete all phases of the test in
sequence.
You must report to the test
site at the scheduled time. You are required to bring personal
protective equipment to wear during the test including as a
minimum: hard hat, work boots, and suitable work clothing.
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
For Task 1, Task 3 and Task 4
an “optimum” time limit has been set. 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
twice as long as the optimum time, you will have lost all the
points allotted to that particular task. The “optimum” time for
each task is stated as part of the task descriptions.
PRE-TEST BRIEFING
While you are waiting to take
your test you will have sufficient time to read this description
of the tasks be performed and review the operator’s manuals and
load charts for the crane(s) you will operate. In addition, you
will be informed of the make and model the crane, the boom
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. A spirit level is available if you wish to
verify level.
- None of the target points
or barrels has been placed at a radius that exceeds the
crane’s rated capacity.
- On telescopic boom
cranes, the boom length has been pre-set. You will NOT be
permitted to telescope at any time.
- All hand signals used
throughout the test will in accordance with ASME B30.5.
Circumventing the
Course
"Circumventing the course" on
the CCO Mobile Crane 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; or
- "leapfrogs" from one leg
of the Zigzag Corridor to another with the chain off the
ground; or
- passes more than four (4)
poles consecutively with the chain off the ground, inside or
outside of the corridor.
The Examiner has the authority
to stop the exam at anytime if he 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. An “unsafe” act includes the following:
- Dropping the ball
or Test Weight (on ground, in barrel, etc.);
- Two blocking of
the crane;
- Uncontrolled or
reckless operation;
- Failure to
respond to a “Stop” signal;
- 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 any time for reasons of safety or if
the Examiner determines the candidate is attempting to
circumvent any task. Please ask the Examiner or proctor you have
questions.
If you are
disqualified due to an unsafe act, your case will be reviewed by
IAI and CCO, and you will be notified as to your eligibility for
rescheduling your practical test.
CANDIDATE ID AND
SIGNATURE
Prior to entering the cab, the Examiner will ask you for a
government issued photo identification such as 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 will review with you the
weather conditions and ask you to sign indicating you understand
the instructions for the test, and 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 weather conditions/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 4, when you will go
back to the beginning of either Task 4a or 4b, as
appropriate.
- You will also 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 which 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 with the exclusion of telescoping. 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 or the barrels.
- You must finish the
Pre-test Familiarization Period with the ball under control
in the Start Circle within the 15 minute period.
- The Examiner will notify
you when there are 10, 5 and 1 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 BALL IN STOP CIRCLE
Optimum Time — 1 minute and 30
seconds.
- At the Examiner’s
indication to start (at which point timing will begin) raise
the ball 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 ball reaches 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.
- The Examiner will give
you a stop signal once the ball and chain are under control.
- Points will be deducted
for the following:
— Dragging or contact of chain outside of the circle.
— Hook or ball touching ground either inside or outside of
the circle.
— Hook or ball contacting any part of the course or crane.
TASK 2: FOLLOW HAND SIGNALS
This task is not timed.
- At the Examiner’s
indication to start, bring the ball and chain from the Stop
Circle to the Designated Area.
- You will be asked to
respond to three standard B30.5 hand signals given by the
Examiner.
- The Examiner’s signals
will be:
— Lower the boom and raise the load, and stop;
— Swing, and stop;
— Lower the load slowly, and stop.
- The Examiner may give the
signals in any sequence.
- At the Examiner’s
indication that this task is concluded, return the overhaul
ball to the Start Circle.
- The Examiner or Proctor
will remove the chain at this time.
TASK 3: PLACE BALL IN BARRELS
Optimum Time:
Small Telescopic Crane — three and one-half (3½) minutes.
Large Telescopic Crane — three and one-half (3½) minutes.
Lattice Boom Crane — four (4) minutes.
- At the Examiner’s
indication to start (at which point timing will begin),
bring the overhaul ball from the Start Circle and place it
into Barrel #1. (If you knock over Barrel #1, at the
Examiner’s indication, proceed to try and put the ball in
Barrel #2.)
- The Examiner will
determine when the horizontal white line painted around the
center of the ball has dropped below the rim of Barrel #1,
and will so indicate to you.
- At the Examiner’s
indication, move the ball from Barrel #1 to Barrel #2.
- The Examiner will
determine when the horizontal white line painted around the
center of the ball has dropped below the rim of the barrel.
Hold the ball in Barrel #2 until instructed by the Examiner
to remove it.
- Timing shall stop when
the ball is completely clear of Barrel #2 and the Examiner
has given you a stop signal.
- Points will be deducted
for the following:
— Moving barrel (2 ins. or more)
— Knocking over barrel
— Hook or ball touching ground
PRE-TASK
FAMILIARIZATION PERIOD
(WITH TEST WEIGHT)
This part of the Test is not scored.
- At the Examiner’s
indication, bring the overhaul ball over the Test Weight
located in the Test Weight Circle.
- The load will be attached
to the crane’s hook by the Examiner or Proctor.
- You are allowed to bring
the Test Weight to the designated area where you can get the
feel of the load, test the brake, etc. before beginning the
zigzag corridor 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 4: NEGOTIATE ZIGZAG CORRIDOR
WITH LOAD
Optimum Time:
Small Telescopic Crane — four (4) minutes each direction.
Lattice Boom Crane — three (3) minutes each direction.
Large Telescopic Crane — three (3) minutes each direction.
This task is divided into two
tasks 4A and 4B. 4A requires you to go through the corridor in a
forward direction. 4B requires you to go through the corridor in
a reverse direction. (This is the only task in which the time
allowed differs depending on the crane type you are operating.)
- At the Examiner’s
direction to start (at which point timing will begin), lift
the Test Weight into the air and swing, boom up or down,
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
chain leaves the ground, or touching 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
- Timing will stop when you
have placed the Test Weight on the ground in the Stop Circle
and the Examiner has given you a stop signal. 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 will indicate the weight is not within the
circle and the task continues to be timed.
- At this time the Examiner
will reconstruct the corridor as necessary.
- At the direction of the
Examiner, at which point timing will begin, lift the Test
Weight from the Stop Circle and travel through the corridor
in reverse fashion.
- Timing will stop when you
have placed the Test Weight on the ground in the Test Weight
circle and the Examiner has given you a stop signal. 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 will indicate the weight is not within the
circle and the task continues to be timed.
- The Proctor will then
detach the Test Weight from the overhaul ball hook.
- At the Examiner’s
direction, swing the hook to the Start Circle and allow the
Examiner to attach the chain in readiness for the next
candidate. Remain in the cab until the Examiner gives you a
clear indication that you may leave the cab.
Set the swing brake and lock before leaving the cab.
POST TEST
PROCEDURES
Once you have completed the practical examination:
- The Examiner will record
your performance.
- The Examiner is not
permitted to review your score sheet or discuss your
performance on the test.
- Exam results will be
mailed to you within approximately twelve (12) working days
of International Assessment Institute’s receipt of the score
sheet.
- For tests on any other
cranes you have made formal application to test on, return
to the candidate briefing area.
- If you have completed all
of your tests, you must leave the test site.
