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.
2. Follow Hand Signals
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.
3. Place Ball in Barrels
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.
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.
4. Negotiate Zigzag Corridor with Load
At the Examiner’s direction to start, 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
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.
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.
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.
