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:
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 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. 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 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.
